Description

  The present invention relates to an apparatus and a program for calculating an altitude difference.

  2. Description of the Related Art A golf support device that provides various information to a golf player while playing a golf course is known. For example, Patent Document 1 describes that information such as the distance from the current location to the green is displayed on the screen.

JP 2013-039423 A

  For golf players, the distance from the current location to a destination such as green is useful information, but the altitude difference between the current location and the destination is equally useful. However, in the conventional golf support apparatuses, there is no model that can display information regarding the altitude difference.

  The reason for this is that it is difficult to obtain the difference in height from the current location to the destination location with a precision that can be used as a reference for play (eg, accuracy of ± 1 m) in a portable small device that can be used on a golf course. It can be mentioned. For example, as a method for obtaining an altitude difference, a method for calculating from an atmospheric pressure, a method for measuring altitude by a GPS function, a method for obtaining from numerical altitude data (mesh data) and latitude and longitude, etc. can be considered. The goal cannot be achieved.

  That is, since the atmospheric pressure fluctuates depending on weather conditions, it is not possible to obtain the altitude at the current point only from the atmospheric pressure. Therefore, even if the altitude of the destination point is known, the altitude difference between the current point and the destination point cannot be obtained. In addition, altitude measurement using the GPS function has low accuracy, and the altitude difference cannot be obtained with an error that can be used as a reference for play. Further, the numerical elevation data has a large data capacity, and it is not realistic to store the numerical elevation data for many golf courses in a portable device. Furthermore, numerical elevation data has a problem that the mesh has coarse meshes (even the most accurate data provided by the Geographical Survey Institute has meshes of 5 meters). Although there is no method, the golf course has a lot of steep terrain, and in places where the altitude difference between meshes is very large (such as depressions), the altitude obtained by interpolation does not match the reality and the player's confidence in the display is impaired It will be.

  The present application discloses an invention that addresses all or some of the above problems or other problems. The present application is not limited to calculating altitude difference as reference information for golf play, and various apparatuses and programs such as an apparatus and program for calculating altitude difference that can be used in various fields are disclosed.

  In the present application, for example, the invention described in each of the following configuration examples is disclosed.

<Configuration example 1>
A portable device having a function of notifying a difference in altitude between a current location in a location area including a reference location and a destination location corresponding to the reference location and the destination location,
Storage means for storing reference area information indicating a position of the reference area, and reference height difference information for calculating a reference height difference that is an altitude difference between the reference area and the destination point;
Position acquisition means for acquiring position information of the current location;
Atmospheric pressure measuring means for measuring atmospheric pressure;
A reference atmospheric pressure holding means for holding a reference atmospheric pressure that is an atmospheric pressure measured by the atmospheric pressure measurement means when the current point is within the reference area;
Altitude difference notification means for calculating and notifying an altitude difference between the current location and the destination location based on the current atmospheric pressure measured by the atmospheric pressure measurement device at the present time, the reference atmospheric pressure, and the reference altitude difference information The apparatus characterized by having.

  According to such a configuration, the user can know the altitude difference between the current location and the destination location within the place area, and can use it to grasp the positional relationship between the current location and the destination location. Knowing the altitude difference between the current location and the destination location is useful for golf, orienteering, skiing, snowboarding, and mountain climbing.

  The place area is an area including a reference area and a destination point. The reference area is an area in the place area, and the destination point is a point separated from the reference area in the place area. When the place area is an area of a route where a person moves from the reference area toward the destination point, an area on such a route, or an area including such a route, the user can move from the current point to the destination. You can know the difference in height. The location area may include one reference area or a plurality of reference areas. The place area may include one destination point or a plurality of destination points. The reference area may correspond to a plurality of destination points. When there are a plurality of reference areas, each reference area may correspond to a plurality of destination points. The destination point may correspond to a plurality of reference areas. When there are a plurality of destination points, each destination point may correspond to a plurality of reference areas.

  The reference area information may be, for example, coordinate data that defines the boundary of the reference area. However, if the reference area information is the coordinate and radius data of the center of the reference area, the amount of data stored in the storage unit can be further reduced. The reference area information may be, for example, point information, for example, latitude / longitude information. For example, a plurality of latitude and longitude information groups may be used, but a single latitude and longitude information may be used. For example, the latitude / longitude point may be set as the reference area, but a predetermined area including the latitude / longitude point may be set as the reference area. The predetermined area may be, for example, a radius of 10 meters with the latitude / longitude point as the center. When there are a plurality of reference areas, the storage means may store the positional information of the plurality of reference areas in association with the target point.

  The reference altitude difference information may be the altitude between the reference area and the destination point, but if the difference between the reference area and the destination point is an altitude difference, the amount of data stored in the storage means can be reduced.

  In this configuration, since the altitude difference is calculated using the atmospheric pressure measured by the atmospheric pressure measurement means, the amount of data stored in the storage means can be reduced as compared with the case of calculating using the digital elevation data stored in the storage means. In addition, the altitude difference can be calculated by faithfully reflecting the undulations in a narrower range. Even if the reference area or the destination point is changed, it is only necessary to change the position information of the reference area and the reference altitude difference information in the storage means, so that the data update is easy. When there are a plurality of reference areas and / or destination points, reference height difference information may be stored in the storage means in association with each combination of the reference area and the destination point.

なお、上記式（１）、（２）における「101325（Pa）」は、海面気圧の標準値であるが、上記式（３）の高度差を求めることが目的であるため、上記標準値を使用しても問題はない。（（式３）で海面気圧の値が標高値算出に与える影響が差し引かれるので、（３）の高度差の算出値に海面気圧の値は殆ど影響しない。） The altitude difference between the current location and the destination location may be obtained, for example, by subtracting the altitude difference between the reference area and the current location from the reference altitude difference. The altitude difference between the reference region and the current point may be calculated using, for example, a well-known mathematical formula indicating the relationship between the atmospheric pressure difference and the altitude difference from the atmospheric pressure difference between the reference atmospheric pressure and the current atmospheric pressure. Such mathematical formulas are well known. For example, the current atmospheric pressure is CP, the reference atmospheric pressure is TP, and the following equations (1) to (3) may be used for calculation.

In addition, “101325 (Pa)” in the above formulas (1) and (2) is a standard value of the sea level pressure, but the purpose is to obtain the altitude difference of the above formula (3). There is no problem using it. (In (Equation 3), the influence of the sea level pressure value on the altitude value calculation is subtracted, so the sea level pressure value has little effect on the altitude difference calculation value in (3).)

  For example, the atmospheric pressure measuring means may be an atmospheric pressure sensor. The position acquisition means may be a GPS receiver, for example. The notification by the notification means may be notification by voice, but may be notification by visual display.

<Configuration example 2>
The relationship between the reference area and the target point is set so that the time normally required for movement from the reference area to the target area is a time that can be considered that a change in atmospheric pressure due to weather fluctuations does not normally occur. apparatus.

  The present configuration pays attention to the fact that the inventor rarely changes so as to greatly affect the altitude difference calculation for a relatively short period of time, and the time normally required for the movement from the reference area to the target area is as follows. Since the relationship between the reference area and the target area is set so that the atmospheric pressure change due to weather fluctuations can be regarded as not normally occurring (for example, within 10 minutes to 30 minutes), while moving from the reference area to the destination point The altitude difference between the current location and the destination location can be calculated accurately. The time when it can be considered that a change in atmospheric pressure due to weather fluctuations does not normally occur may be a time when no atmospheric pressure change occurs in cases other than extreme weather conditions such as a typhoon. The pressure change does not occur, for example, when the change in the pressure difference due to the pressure change has a pressure change smaller than an error allowed in light of the purpose of use of the apparatus. The relation between the reference area and the target point may be a positional relation, and the positional relation may be determined in consideration of the speed that can be taken by the moving means from the reference area to the target area. For example, when the moving means is on foot, the distance may be within a few tens of minutes on foot. In this configuration, even when the destination point cannot be visually recognized from the current location due to an obstacle (for example, a hill or a forest), the user may be able to know the altitude difference between the current location and the destination location.

<Configuration example 3>
The reference area is a place area that can be regarded as having no difference in altitude, and is a start position in the place area when the user carries the device and aims at the target point. Device to do.

  In this configuration example, the user can move from the start position in the local area toward the target point, and thereafter can know the difference in altitude between the current position in the local area and the target point. Further, since it can be considered that there is no altitude difference in the reference area, the altitude difference between the current point and the destination point can be accurately calculated regardless of the reference atmospheric pressure measured at any point in the reference area. The fact that there is no difference in altitude may be, for example, an altitude difference that is smaller than an error allowed in light of the purpose of use of the device.

<Configuration example 4>
The location area includes a plurality of sets of the reference area and the destination point corresponding to the reference area,
The storage means stores the reference area information and the reference height difference information for each of the sets,
The apparatus further includes set selection means for selecting the set,
The altitude difference notification means includes the current atmospheric pressure, the reference atmospheric pressure measured by the atmospheric pressure measurement means when the current point is in the reference area of the set selected by the set selection means, and the reference for the set. An apparatus for calculating an altitude difference between the current location and the destination location based on altitude difference information.

  If comprised in this way, the altitude difference of the present location and the destination point about the group selected from the plurality of groups may be calculated and notified. For example, the set selection means may select a set based on the position information of the current location. For example, a set including a reference region closest to the current location may be selected.

<Configuration example 5>
The spatial region includes a plurality of partitioned regions;
The partitioned area includes the set, respectively.

  If configured in this way, the location area is a relatively wide area, and it takes a long time to move from one point to another within that area, and the difference in altitude is greatly affected during that time. Even if a change in weather conditions can occur, the location area is divided into a plurality of divided areas, and within each divided area, a short time that does not cause a change in weather conditions (for example, within 10 minutes) By setting the reference area and the destination point so that it can move from the reference area to the destination point within 30 minutes), the difference in altitude between the current point and the destination point can be accurately calculated in each divided area. . For example, if the location area is a mountain course, and it takes a long time (for example, several hours) to move from the mountain entrance to the top, the mountain course is divided into a plurality of divided areas that can be moved in a relatively short time. It is good to divide.

<Configuration example 6>
The altitude difference notifying means notifies an altitude difference between the current location and the target location included in the one partitioned area when the current location is within one partitioned area.

  In the present configuration example, it may be possible to notify the altitude difference between the current location and the destination location within each partitioned area.

<Configuration example 7>
The device is characterized in that the local area is an area within a golf course, and the destination point is a point on a green.

  In this configuration, information useful for golf play such as the difference in altitude between the current location and the location on the green may be provided to the player at the golf course. In golf, the time for playing a one-hole golf course is relatively short (usually about 10 to 20 minutes), and during that time, it is greater than the accuracy (eg, ± 1 m) required as reference information for play. Since the weather conditions rarely change so as to affect the difference in altitude, if the location area is a one-hole golf course in the golf course, the current location and the destination location are sufficiently accurate as reference information for play. It is good because the altitude difference can be provided to the player. In the configuration example 7 that cites the configuration example 5, if the location area is a golf course having a plurality of holes (for example, a golf course from the 1st hole to the 9th hole) and the partition area is a 1-hole golf course, each hole It is good to know the altitude difference between the current position and the point on the green at the golf course. The point on the green may be, for example, the center of gravity of the green. The calculation and notification of the altitude difference between the reference area and the current location in this configuration may be performed at intervals of, for example, 5 seconds. This is because a difference in altitude may change greatly when a player walks for about 5 seconds on a golf course.

<Configuration example 8>
The reference area is an area including a tea ground.

  In this configuration, because the player always passes the tee ground in accordance with the rules of golf, it is possible to measure the reference atmospheric pressure more reliably by setting the reference area to include the tee ground, Since the area including the tee ground often has a small difference in altitude, the difference in altitude between the current point and the destination point can be accurately calculated.

<Configuration example 9>
The storage means further stores reference point information indicating a position of a reference point located in the reference region,
The reference altitude difference is an altitude difference between the reference point and the destination point.
The reference atmospheric pressure holding means holds the atmospheric pressure measured by the atmospheric pressure measuring means as the reference atmospheric pressure when the current point is closest to the reference point.

  In this configuration, it is highly probable that the closer to the reference point, the smaller the difference in altitude from the reference point is, so the difference in reference altitude is the difference between the reference point and the destination point, and the current point is closest to the reference point as the reference pressure. By using the pressure measured at the time, the altitude difference between the current point and the destination point can be calculated with higher accuracy.

<Configuration example 10>
The spatial region includes a plurality of the reference regions;
The storage means stores the reference area information and the reference height difference information about the reference area for each of the plurality of reference areas,
When the current location passes through the plurality of reference areas in the process of moving to the destination location,
The altitude difference notification means calculates an altitude difference between the current location and the destination location using the reference altitude difference information for the reference area that is closest to the current location.

  In this configuration, the reference altitude difference information for multiple reference areas is stored, and the altitude difference between the current position and the destination point is calculated using the reference altitude difference information for the reference area that is closest to the current position. It is good because it is highly probable that the current altitude difference can be calculated.

<Configuration Example 11>
The apparatus characterized in that the reference region is a geometric shape.

  In this configuration, since the reference area has a geometric shape, the reference area may be easily set. The geometric shape may be a circle, a square, or the like. For example, when an external shape of an area (for example, a tee ground) to be included in the reference area is determined by looking at an aerial photograph or by actually measuring with GPS, a geometric shape including the external shape is set as the reference area. Good. For example, in the case of a circle, a point (for example, the center of gravity) within the outer shape may be selected as a reference point, and a circle drawn so as to include the outer shape with the reference point as the center may be set as the reference region. Inclusion may be circumscribed, for example. For example, the reference area may be defined by data indicating a geometric shape. For example, vector data indicating a geometric shape, mathematical formulas indicating a geometric curve, and data of coefficients thereof may be used, but it is preferable to simply use center coordinate data and radius data of a circle.

<Configuration example 12>
The altitude difference informing means has a function of informing the reference altitude difference in place of the altitude difference between the current location and the destination location when the current location is within the reference area.

  In this configuration, when the current location is within the reference area, a more reliable reference altitude difference may be notified. For example, if the reference area is an area that includes the tee ground, the player can be sure of a highly reliable altitude difference with a margin when the player is at the tee ground. . In addition, when the said current point is outside the said reference | standard area | region, it is good to provide the function which calculates and alert | reports the altitude difference of the said present point and the said destination point based on present atmospheric pressure, reference | standard pressure, and reference | standard altitude difference information.

<Configuration Example 13>
The altitude difference notification means notifies the reference altitude difference and the altitude difference between the current location and the destination location in the same notification mode.

  In this configuration, it is not necessary to give the user a sense of incongruity or complexity due to the notification mode changing depending on whether the altitude difference displayed by the altitude difference notification means is the reference altitude difference or the altitude difference between the current location and the destination location. The notification mode is the same, for example, the display position, font, display size, display color, etc. when displaying the altitude difference on the display screen may be the same.

<Configuration Example 14>
The storage means further stores position information of the destination point,
The apparatus according to claim 1, wherein when the distance between the current point and the destination point is equal to or less than a predetermined value, the altitude difference notifying means does not notify the altitude difference.

  When the user comes close to the destination point, it becomes easier for the user to measure the altitude difference between the current point and the destination point. On the other hand, the closer the current point is to the destination point, the longer the time from the reference air pressure measurement time. It is assumed that the calculation error of the altitude difference due to weather fluctuations during that period is likely to increase. In this configuration, since the altitude difference is not notified when the distance between the current location and the destination location is below a certain value, the possibility of giving the user the impression that the reported altitude difference does not match the visual measurement is reduced. I can do it. In the range of 30 m, it is easy for a normal player to measure the altitude difference, so the constant value is preferably 30 m.

<Configuration Example 15>
History storage means for storing a history of the current location entering the reference area;
The altitude difference notifying means makes the altitude difference non-notifying when there is no history that the current location has entered the reference area.

  When the current location is not yet in the reference area, the altitude difference between the current location and the destination location cannot be calculated, so the user can be informed that the altitude difference has not been calculated by not reporting the altitude difference. I can do it. The non-notification mode in this configuration may be different from the non-notification mode in Configuration Example 12. For example, when the altitude difference notification by the altitude difference notification means is performed by displaying a digital numerical value, the non-notification of the configuration example 12 is performed in such a manner that the numerical value is not displayed (the display position of each digit of the numerical value is made blank). The non-notification in the configuration example 13 is preferably performed in a mode in which a bar is displayed at the display position of each digit of numbers such as “---”.

<Configuration Example 16>
The spatial region includes a plurality of the destination points;
The altitude difference notifying means calculates and notifies an altitude difference between the current location and the destination location for each of the plurality of destination locations.

  In this configuration, since the altitude difference between the current location and the destination location for multiple destination locations is displayed on a single screen, the user can operate the current location and destination location for each destination location without having to operate the device. It is good because you can know the altitude difference between the points. For example, the location area may have two left and right destination points, such as a green on a golf course, and if the right or left destination point can be used changes for each location area, It is not necessary to perform an operation of selecting a target destination point for each area. The notification of the altitude difference for each of the plurality of destination points may be displayed on a single screen, for example.

<Configuration Example 17>
The storage means further stores position information of the destination point,
The apparatus further comprising distance notifying means for notifying a distance between the current point and the destination point.

  In this configuration, since the distance and altitude difference between the current location and the destination location are notified, the user may be able to more easily understand the positional relationship between the current location and the destination location.

<Configuration Example 18>
A program for causing a computer to realize the function of the apparatus according to any one of Configuration Examples 1 to 17.

  The configurations described in the above-described configuration examples and the like may be combined to the extent that no contradiction occurs. In addition, a new configuration example may be configured by arbitrarily combining the constituent elements described in each configuration example and the like within a range where no contradiction occurs.

  Hereinafter, a golf support device and a program thereof according to an embodiment of the present invention will be described with reference to the accompanying drawings. The golf support device of the present embodiment displays the course layout of the actual golf course, measures the latitude and longitude of the current location, and moves the player along with the distance and altitude difference between the current location and the destination such as green. This is a golf support device that notifies in real time, and is also referred to as a golf navigation device.

  1 and 2 show a preferred embodiment of a golf support apparatus 1 according to the present invention. The golf support apparatus 1 includes a display unit 3 on the upper surface of a flat, substantially rectangular case 2. The display unit 3 constitutes a touch panel. If the backlight is built in and the backlight of the screen is turned on when a button is operated or the screen is touched, visibility is improved. A charging lamp 8 is disposed on the rear side of the upper surface of the case 2.

  A power button 4 is arranged on the side surface of the case 2. The power button 4 is used not only for turning the power on / off but also as a point registration button and a touch / lock switching button for touch panel operation. Specifically, when the control unit 11 recognizes that the power button 4 is pressed and held for a long time (for example, 2 seconds or more) in the power-off state, the power is turned on, and the control unit 11 displays a predetermined main menu screen on the display unit 3. indicate.

  Further, when the power button 4 is operated for a short time in the power-on state, the control unit 11 executes a point registration function. The point registration function will be described later. When the power button 4 is pressed and held while the power is on, the control unit 11 alternately switches the lock / release of the touch panel. That is, if the current state is locked, the operation is canceled and the operation using the touch panel is enabled. If the current state is the release state, the operation is switched to the locked state and the operation using the touch panel is disabled. The current state is notified by an icon drawn at a predetermined position on the display unit 3.

  Further, an openable / closable terminal cover 7 is attached to the rear surface of the case 2, and when the terminal cover 7 is opened as shown in FIG. 1B, the microUSB terminal 9 is exposed. The microUSB terminal 9 can be charged by connecting an AC adapter.

  The case 2 includes a control unit 11, a storage unit 12 connected to the control unit 11, a GPS receiving unit 13, an atmospheric pressure sensor 14, a geomagnetic sensor 15, a posture sensor 16, and a battery 17.

  The control unit 11 includes a microcomputer including a CPU, ROM, RAM, flash memory, various peripheral circuits, an interface, and the like. When the power is turned on, the controller 11 is supplied with power from the battery 17 and starts operating. The control unit 11 executes various processes described later by implementing the OS and application program recorded in the flash memory or the like on the RAM and executes them, thereby realizing various functions. The control unit 11 is connected to the display unit 3, the power button 4, and the like. The control unit 11 receives an operation signal from the power button 4 and controls the display on the display unit 3.

  The storage unit 12 is configured by a recording medium such as an internal memory or a removable external recording medium (such as a micro SD memory card). The storage unit 12 includes a golf course data storage unit 12a and a processing data storage unit 12b.

  The golf course data storage unit 12a stores golf course data that is data related to a plurality of golf courses at one or more golf courses in and outside of Japan. In the present embodiment, a golf course for one hole is called a “golf course”, and a plurality of golf courses (for example, a golf course from 1st hole to 9th hole, 10th hole to 18th hole) Is called “course”. A golf course (or an area including the same), a course (or an area including the same), and a golf course (or an area including the same) may correspond to the “location range” in the claims.

  Here, in order to explain golf course data, a general golf course 20 will be described with reference to FIG.

  As shown, the golf course 20 includes a tee ground 21 and a green 22. In the figure, a golf course 20 having two tee grounds 21 and two greens 22 is shown. In general, the number of teeing grounds in a one-hole golf course 20 is one to three. In general, there may be only one green on the golf course 20 with one hole, or there may be two greens on the left and right. When there are a plurality of tee grounds 21, it is generally determined which tee ground 21 is used by specifying a golf course, agreement between players, and the like. When there are two greens 22 on the left and right, which green 22 is used is generally determined by the designation of the golf course. The golf course 20 may have one or more obstacles 24 such as a bunker or a pond. The golf course 20 may include fairways, roughs, and the like. There is a moving route 23 such as a cart road between one golf course 20 and the golf courses before and after the golf course 20 (the golf course 20 of the first hole is between the clubhouse and the like).

  The golf course data includes a layout image and hole data for each golf course 20 at each golf course.

  The layout image is image data for displaying the layout (shape) of each golf course 20 on the display unit 3.

  The hole data includes section latitude / longitude, object data, tee data, and automatic movement point data.

  The section latitude / longitude is the latitude / longitude of the four corners of the section area 25 set for each golf course 20. The partition area 25 is an area that includes an area where the player can move during play on the golf course 20. In the present embodiment, the partition region 25 has a quadrangular shape. The partition area 25 is set as a sufficiently wide area including the golf course 20.

  The object data is data indicating the latitude and longitude of various objects in the golf course 20. Specifically, the object is from a destination point 28 set on the green 22, an edge closer to the tea ground 21 of the green 22 (hereinafter referred to as a “front green edge”), and a tea ground 21 of the green 22. It includes an edge on the far side (hereinafter referred to as a “green side green edge”), an obstacle 24, and the like. The destination point 28 is set near the center of the green 22. More specifically, the center of gravity of the polygonal shape when the polygonal shape that roughly matches the green 22 is drawn by looking at the aerial photograph or the course design drawing is set as the target point 28. For the golf course 20 having two greens 22 on the left and right, the latitude and longitude of the destination point 28, the front side green edge, and the front side green edge of each of the left and right greens 22 are stored as object data. (Hereinafter, the destination point 28 of the left green 22 is referred to as “left destination point 28”, and the destination point 28 of the right green 22 is referred to as “right destination point 28”.) When there are a plurality of obstacles 24, The latitude and longitude of each obstacle 24 is stored as object data.

  The tee data is data related to the reference area 26 set for each tee ground 21 in the golf course 20.

  The reference area 26 is set as a circular area including the tee ground 21. Specifically, the outer shape of the tee ground 21 (or an area where the tee ground 21 may be set) is determined by looking at aerial photographs, course design drawings, etc., and drawn so as to circumscribe the outer shape. A circle is the reference area 26. When there are a plurality of tea grounds 21, a reference area 26 is set for each tea ground 21, and tee data is set for each reference area 26. Although the figure shows a case where a plurality of reference areas 26 do not have overlapping areas, the plurality of reference areas 26 may have overlapping areas.

  The tee data includes tee coordinates, tee radius, and left and right reference height differences. The tee coordinates are the latitude and longitude of the reference point 27 that is the center of the reference region 26. The tee radius is the radius of the reference region 26. The reference area 26 is defined by a tee coordinate and a tee radius. By defining the reference area 26 with the tee coordinates and the tee radius, the amount of data stored in the storage unit 12 can be reduced.

  The left reference altitude difference is the altitude difference between the reference point 27 and the left destination point 28, and the right reference altitude difference is the altitude difference between the reference point 27 and the right destination point 28. The difference between the left and right reference altitudes is calculated from the altitude value at the reference point 27 and the altitude value at the left and right destination points 28. These elevation values are the four elevations closest to the target point (reference point 27 or destination point 28) among the base map information numerical elevation model elevation points, which are grid-like elevation point data prepared by the Geospatial Information Authority of Japan. It is calculated using a value obtained by smoothing the point value. For the golf course 20 having only one green 22, only the left reference height difference is set.

  The automatic movement point data is data relating to the movement area 29 for determining the movement of the player from the previous golf course (or club house) to the golf course 20. The movement area 29 is a circular area set in the vicinity of the movement route 23 on the near side of the golf course 20. The movement area 29 is set to an appropriate size and position that can reliably determine the movement of the player to the golf course 20. A plurality of movement areas 29 are set when it is necessary to determine the movement of the player to the golf course 20, such as when there are a plurality of movement routes 23. The automatic movement point data includes the latitude and longitude and the radius (automatic movement point radius) of the center point of the movement area 29.

  In addition to the above, the golf course data is information related to the golf course (golf course ID and category, golf course name (kanji, reading, English, abbreviated), etc. ), Country code, telephone number, postal code, prefecture ID (region overseas), prefecture name (region name overseas), time zone, address, golf course division maximum latitude / longitude, golf course division minimum latitude / longitude, etc.) And course information (course ID, course name (kanji, reading, English, abbreviated), hole number addition number, next course ID, etc.), other information related to the golf course (hole number, PAR number, etc.) Including. Further, the golf course data includes altitudes such as the reference points 27 and objects as surplus data.

  The processing data storage unit 12b stores a numerical value used in a later-described altitude difference calculation display process, a calculated numerical value, and the like.

  The GPS receiving unit 13 measures the latitude and longitude of the current location based on a signal from GPS hygiene and provides it to the control unit 11. The atmospheric pressure sensor 14 measures the current atmospheric pressure and provides it to the control unit 11. The geomagnetic sensor 15 obtains the azimuth and angle that the golf support apparatus 1 faces by measuring the geomagnetism and provides it to the control unit 11. The posture sensor 16 includes an acceleration sensor and a gyro sensor, and provides the control unit 11 with information indicating whether the golf support apparatus 1 is in the portrait orientation or the landscape orientation.

  Hereinafter, the function of the control unit 11 will be described based on a specific display screen. When the control unit 11 determines that the latitude / longitude of the current location measured by the GPS receiving unit 13 has passed the moving region 29, the control unit 11 reads out the hole data of the golf course 20 including the free moving point data for the moving region 29. The golf navigation screen 30 displaying the layout image of the golf course 20 is displayed on the display unit 3. FIG. 4 shows an example of the golf navigation screen 30 when the golf course 20 has two left and right greens 22 (when the hole data includes object data for two left and right destination points 28).

  In the center of the golf navigation screen 30, a layout image of the golf course 20 currently being played is displayed so that the green is on top. In addition, a self-icon 31 is displayed at a position corresponding to the place where the user is in the drawn layout image (latitude and longitude of the current location acquired from the GPS receiver 13), and corresponds to the pin position (cup position) on the green. A flag icon 32 is displayed at the location. Thereby, the player can know the course layout, the direction of the green 22, and the like. Further, a distance 33 from the current position to an obstacle such as a pond or a bunker on the golf course 20 is displayed, and further, a concentric circle line 34 centered on the self icon 31 and a position on the concentric circle line 34 from the current position. Distance 35 is displayed. Thereby, the player can know the distance to the obstacle on the golf course 20 and the approximate distance to an arbitrary place on the golf course 20. By knowing these pieces of information, the user can confirm how to capture each hole even in the first course. The distance 33 to the obstacle can be switched between display / non-display by operating a button displayed below the golf navigation screen 30 or the like.

  The control unit 11 further detects the direction in which the present device is directed based on the output of the geomagnetic sensor 15 and draws the direction as a direction indicating line (dotted line) 36 composed of an arrow and a dotted line on the golf navigation screen 30. To do. The starting point of the direction indicating line 36 is the current position (self icon 31). As a result, when the user changes the direction while holding the apparatus, the direction indicating line 36 on the display screen turns in accordance with the direction of the apparatus. By doing so, it can be confirmed that there is a target point ahead. Therefore, even when the field of view is bad or far away due to fog or the like, or when trees or obstacles exist, the direction can be accurately known.

  Further, the control unit 11 displays the green data display units 37L and 37R on the left and right sides of the golf navigation screen 30, and displays the distance and altitude difference to the object on the left green 22 in the left green data display unit 37L. In the right green data display section 37R, the distance to the object on the right green 22 and the altitude difference are displayed.

  More specifically, the control unit 11 displays the three distances D1 to D3 and the altitude difference ED in the upper and lower four stages in the green data display units 37L and R. The first stage distance D1 is the distance between the current point and the shore side green edge, the second stage distance D2 is the distance between the current point and the destination point 28, and the fourth stage distance D3 is the distance between the current point and the current point. This is the distance of the front green edge. The control unit 11 calculates and displays these distances from the latitude and longitude of the current location and the latitude and longitude of the destination location 28 and the like stored in the object data. The third level altitude difference ED is the altitude difference between the current point and the destination point 28. A method for calculating the altitude difference ED will be described later. The units of the distances D1 to D3 and the altitude difference ED displayed on the green data display units 37L and 37R are meters or yards, and the control unit 11 can operate the buttons displayed below the golf navigation screen 30 by the user. Switch between meter display and yard display accordingly. The control unit 11 calculates the distances D1 to D3 and the altitude difference ED only when the current location measured by the GPS receiving unit 13 is within the partition area 25 and the current location cannot be measured. When the current point is outside the partition area 25, “---” is displayed as the distances D1 to D3 and the altitude difference ED.

  Thus, since the distances D1 to D3 and the altitude difference ED for both the left and right greens 22 are displayed, the player can operate the device even when the right or left green 22 is changed for each hole. Even without performing the above, it is possible to know the distances D1 to D3 and the altitude difference ED for the green 22 to be known.

  Further, the control unit 11 determines that the distance D1 between the current point and the shore green edge is green, the distance D2 between the current point and the destination point 28 is white, and the distance D3 between the current point and the front green edge is red. The altitude difference ED is displayed in the same color as the distance D2 between the current location and the destination location 28. Thus, the player intuitively knows that the distances D1 to D3 are distances to different points, and that the distance D2 and the altitude difference ED are the distance and altitude difference between the same points (the current point and the destination point 28). Easy to understand.

  5 and 6 show the golf navigation screens 30a and 30b displayed by the control unit 11 when the player performs a flick operation on the display unit 3 while the golf navigation screen 30 of FIG. 4 is displayed. Show. FIG. 5 shows a golf navigation screen 30a displayed when a left flick operation is performed. Only the left green data display portion 37L is displayed on the left side of the screen, and a hazard indicating the distance to the obstacle 24 is displayed on the right side of the screen. A distance display unit 38 is displayed. FIG. 6 shows a golf navigation screen 30b displayed when a right flick operation is performed. Only the right green data display portion 37R is displayed on the right side of the screen, and a hazard indicating the distance to the obstacle 24 is displayed on the left side of the screen. A distance display unit 38 is displayed. In this way, the player displays both the left and right green data display portions 37L and R according to his / her preference (golf navigation screen 30), or one of the left and right green data display portions 37L and R and the hazard distance display portion. 38 (golf navigation screens 30a, 30b) can be selected. When the golf course 20 has only one green 22 (when the hole data does not include object data for the right destination point 28), the control unit 11 always displays the golf navigation screen 30a similar to FIG. Even when the flick operation is performed, the golf navigation screens 30 and 30b in the modes of FIGS. 4 and 6 are not displayed. In this specification, when it is not necessary to distinguish between the golf navigation screens 30, 30 a, 30 b, they are simply referred to as “golf navigation screen 30”.

  As shown in FIG. 4, the control unit 11 displays a hole icon 40 indicating information on the golf course 20 such as a hole number and the number of pars at the top of the golf navigation screen 30. The hole icon 40 shown in the figure indicates that the golf course 20 currently being displayed is the eighth hole and the number of pars is “4”. When the hole icon 40 is touched, the control unit 11 changes the golf course 20 displayed on the golf navigation screen 30. For example, if the golf course 20 of the 8th hole is displayed as shown in the drawing, the control unit 11 sequentially displays the 9th hole, the 10th hole, and the like on the display unit 3 every time the hole icon 40 is touched.・ ・ Display the golf navigation screen 30 for the golf course 20.

  On the golf navigation screen 30, a distance between three points can be displayed by touching an arbitrary point on the layout image. That is, when the control unit 11 detects a touch operation on the layout image, the control unit 11 displays the icon 41 at the touched position as shown in FIG. 7, and from the current point to the touched point. The distance 42 and the distance 43 from the touched point to the destination point 28 are calculated and displayed. Thereby, the player can know the distance of the second and third shots, and can set an accurate course strategy.

  In addition, the player can register a point on the golf course 20 based on a switch operation or the like while the golf navigation screen 30 is displayed. That is, when the power button 4 is operated shortly, the control unit 11 acquires the latitude and longitude of the current location from the GPS receiving unit 13 and stores them in the storage unit 12 together with the time at that time. The point registration can be used, for example, for recording a point where the ball is actually hit. When the spot-registered spot exists in the layout image displayed on the golf navigation screen 30, the control unit 11 draws the spot registration icon 44 at the corresponding position as shown in FIG.

  In the state where the golf navigation screen 30 is displayed, when it is detected by the signal from the posture sensor 16 that the golf support apparatus 1 is turned sideways, the control unit 11 displays the display on the display unit 3 in FIG. It switches to the horizontal golf navigation screen 50 shown. In the horizontal golf navigation screen 50, the vicinity of the green 22 in the layout image is enlarged and displayed. Thereby, the player can see a detailed state near the green 22 by a simple operation of changing the orientation of the apparatus. In the horizontal golf navigation screen 50, the control unit 11 includes a left green data display unit 51L that displays a distance D2 from the current point to the left destination point 28 and a distance D3 to the front green edge of the left green 22; While displaying the right green data display portion 51R displaying the distance D2 from the point to the right destination point 28 and the distance D3 to the front green edge of the right green 22, the distance to the heel side green edge and the current point The height difference between the destination point 28 and the destination point 28 is not displayed. This simplifies the screen and makes it easier for the player to grasp the display contents. When the horizontal golf navigation screen 50 is displayed, if the golf support device 1 is detected to be in the vertical orientation by the signal from the posture sensor 16, the control unit 11 displays the display on the display unit 3 as golf. Switch to the navigation screen 30.

  FIG. 10 shows a flow of the calculation display process of the altitude difference ED executed by the control unit 11 when the current point of the golf support apparatus 1 is located in the partitioned area 25 of the golf course 20. The control unit 11 executes this calculation display process using the hole data read from the golf course data storage unit 12a when the golf navigation screen 30 is displayed. As described above, when the golf course 20 has two left and right greens 22, the altitude difference ED is calculated and displayed in the left and right green data display portions 37 </ b> L and 37 </ b> R. Here, processing related to the calculation display of the altitude difference ED (the altitude difference ED displayed on the left green data display unit 37L) for the left green 22 will be described. However, in the description, the processing related to the calculation display of the altitude difference ED for the left green 22 may be mentioned.

  The control unit 11 is based on the condition that the control unit 11 has determined that the current point has passed the moving region 29 based on the latitude and longitude of the current point measured by the GPS receiver 13 and the automatic moving point data of the golf course 20. The calculation display process is started.

  When the calculation display process starts, in step S1, the control unit 11 sets the minimum tee distance TLm used as a process parameter to an initial value. As this initial value, a numerical value (for example, 256 m) sufficiently larger than the tee radius of all the reference areas 26 stored in the golf course data is used.

  In subsequent step S2, the control unit 11 specifies the reference region 26 of the reference point 27 closest to the current point from the latitude and longitude of the current point measured by the GPS receiving unit 13 and the tee coordinates of each reference region 26 (hereinafter, referred to as “the reference point 26”). The distance TL between the current point and the reference point 27 of the nearest tee area NT is calculated together with the reference area 26 identified in step S2 as “nearest tee area NT”.

  In the subsequent step S3, the control unit 11 determines whether or not the current point is in the nearest tee area NT, that is, the distance TL is the tee radius of the nearest tee area NT (the tee radius of the nearest tee area NT is “tee radius Tr”). Or not.) Judge whether it is less.

  If the determination in step S3 is affirmative (Yes), the controller 11 determines in step S4 whether the distance TL is less than the minimum tee distance TLm.

  If the determination in step S4 is affirmative (Yes), the control unit 11 updates the value of the minimum tee distance TLm to the distance TL in step S5. As described above, when step S5 is executed, the minimum tee distance TLm is smaller than the initial value. Therefore, in step S8 described later, the player determines whether the minimum tee distance TLm matches the initial value. After entering the golf course 20 for the first time, it is possible to determine whether there is a history of entering the reference area 26 even once.

  In step S6, the control unit 11 determines the difference between the left and right reference altitudes for the latest tee area NT (the left reference altitude difference is “left reference altitude difference LTD”, and the right reference altitude difference is “right reference altitude difference RTED”. Are extracted from the hole data, and the left and right reference altitude differences LTED and RTED and the reference pressure TP, which is the measurement value of the pressure sensor 14 at that time, are stored in the processing data storage unit 12b. In step S6, the left and right reference altitude differences LTD and RTED for the reference area 26 of the reference point 27 where the current point is closest in the course of movement of the player within the golf course 20, and the reference atmospheric pressure TP at the point of closest approach are obtained. It is held in the processing data storage unit 12b. If the determination in step S4 is negative (No), the control unit 11 skips steps S5 and S6.

  In step S7, the control unit 11 displays the left reference altitude difference LTD stored in the processing data storage unit 12b as the altitude difference ED of the green data display unit 37L. Thereby, when the golf support apparatus 1 is in the reference area 26, the altitude difference between the reference point 27 and the destination point 28 calculated in advance based on the elevation value of the base map information numerical elevation model elevation point is displayed on the display unit 3. Is done. Therefore, the player can see an accurate altitude difference between the reference point 27 and the left destination point 28 at a timing when there is a margin for confirming the altitude difference, such as waiting for another player's tee shot.

  If the determination in step S3 is negative (No), that is, if the current location is not in the reference area 26, the process proceeds to step S8.

  In step S8, the control unit 11 determines whether the minimum tee distance TLm is equal to the initial value. If the determination is affirmative (Yes), that is, if there is no history of entry into the reference area 26, the control unit 11 does not calculate the altitude difference ED, and in step S9, the green data display unit A bar ("---") is displayed as an altitude difference ED of 37L. Thereby, the player can know that the altitude difference ED between the current location and the destination location 28 has not been measured.

  If the determination in step S8 is negative (No), that is, if the minimum tee distance TLm is smaller than the initial value, the control unit 11 determines the distance DLG from the current point to the left destination point 28 in step S11. It is calculated to determine whether the distance DLG is less than a certain value GN. If the determination is affirmative (Yes), in step S12, a blank (“”) is displayed as the altitude difference ED of the green data display unit 37L. As a result, the altitude difference ED is not displayed in the range below the certain value GN from the green, which is considered to be easy for the player to measure the altitude difference, and the altitude difference that can be caused when the altitude difference ED that does not match the player's eye is displayed. It is possible to prevent a decrease in the player's confidence in the ED display. It should be noted that 30 m is used as the constant value GN in step S11 when the green data display portions 37L and 37R are displayed in meters, and 30 yards are used when displayed in yards. Regardless of meter display or yard display, when 30 m is used as the constant value GN, for example, 30 m is approximately 33 yards, so in the yard display, a blank (“ ) To prevent the user from feeling uncomfortable.

  If the determination in step S11 is negative (No), in step S13, the control unit 11 measures the reference atmospheric pressure TP and the left reference altitude difference LTD stored in the processing data storage unit 12b, and the measurement of the atmospheric pressure sensor 14 at that time. Based on the current atmospheric pressure CP as a value, a calculated value CED of the altitude difference between the current point and the left destination point 28 is obtained and displayed as the altitude difference ED of the green data display portion 37L.

As a specific calculation method, the control unit 11 calculates the altitude difference ΔH by the following formulas (1) to (3), and subtracts the altitude difference ΔH from the left reference altitude difference LTD to obtain the calculated value CED. Ask.

  In golf, the time required to play one golf course 20 is about 10 to 15 minutes, and it is considered that the influence on the current atmospheric pressure CP due to the change in weather conditions within that time is very small. Therefore, the altitude difference between the current point and the destination point 28 can be accurately calculated and displayed, and the player can use the displayed altitude difference ED as a reference for play.

  After executing steps S7, S10, S12, and S13, the control unit 11 waits for about 1 second, and then shifts the process to step S2. Thereby, the processing of steps S2 to S13 is repeatedly executed, and the display of the altitude difference ED is updated about every 1 second.

  The preferred embodiments have been described above, but the shapes, dimensions, materials, functions, operation modes, control modes, control parameters, operation modes, etc. of the devices, systems and programs or their elements, members, etc. in the above embodiments are examples. These can be changed.

  For example, in the above embodiment, the case of the golf support device 1 used on a golf course has been described as an example. However, the purpose of use of the device of the present invention is not limited to golf, and the current point in orienteering, skiing, snowboarding, mountain climbing, etc. It is also possible to use a device that notifies the altitude difference of the destination point.

  In the above-described embodiment, the case where the reference area 26 is an area including a tea ground has been described. However, the reference area may be an area that coincides with the tea ground or may be an area other than the tea ground. Moreover, there is no restriction | limiting in the area of a reference region, For example, the area of a reference region may be infinitely narrow. For example, the reference region may be a single point having no area.

  In the above embodiment, the case where the destination point 28 is near the center of the green 22 (more precisely, the center of gravity of a polygon drawn so as to roughly match the outline of the green 22) has been described. Other points, for example, other points in the green 22 or points outside the green 22 may be used. The destination point does not need to be a single point having no area, and may be a set of a plurality of points, or may have a certain area.

  Moreover, you may comprise so that a destination point can be set by a user's operation. For example, in many golf courses, the position of the cup changes from day to day. Therefore, if the user can set the cup position of the day as the destination point, it is more convenient because the altitude difference between the current point and the cup position of the day is displayed. For example, the destination point may be set such that the control unit 11 sets the latitude and longitude of the position touched by the user on the golf navigation screen 30 or the horizontal golf navigation screen 50 as the destination point. When the destination point is configured to be set by the user's operation, for example, the elevation value of the base map information numerical elevation model elevation point in the green 22 (or near the green 22) is stored in the storage unit 12 as hole data, The control unit 11 calculates the elevation value of the destination point set by the user using the values obtained by smoothing the elevation values of the four base map information numerical elevation model elevation points closest to the destination point set by the user The reference altitude difference may be calculated using the calculated altitude value.

  The method of calculating the altitude difference between the current location and the destination location, the type and format of the data used for the calculation, etc. are not limited to the aspect of the embodiment, and can be any other appropriate method, type and format.

  Moreover, although the control part 11 demonstrated the case where the control part 11 memorize | stores the latitude longitude of the present location when the point registration operation was performed in the memory | storage part 12, for example, operation of point registration was performed Sometimes, the control unit 11 changes the altitude difference between the current point and the destination point by the display calculation process at that time together with the latitude and longitude of the current point at that time (the left and right green data display units 37L and R in Steps S7 and S13). The displayed altitude difference ED) may be recorded in the storage unit 12. The data recorded in this manner may be configured to be displayed on the display unit 3, or may be configured to be output to a personal computer or the like via the microUSB terminal 9 or the like, and may be displayed on the personal computer. The data should be displayed by calculating the distance and altitude difference between the two registered points, so that the player can fly distance and altitude difference (the altitude difference between the points where the ball flew). ) Since the flying distance of the ball is affected by the difference in altitude (whether it is a shot shot or a shot down), it is useful for the player to know the altitude difference together with the flight distance.

  In addition, although the golf support apparatus 1 shown in FIG. 1 is in a form suitable for hand-held carrying, the golf support apparatus 1 can also be an apparatus that can be worn on the wrist or the like in the form of a wristband or the like. When it is possible to attach to the wrist or the like, it is possible to detect the player's swing with an acceleration sensor or the like, and the control unit automatically performs point registration for the point where the swing is detected.

  The base incorporated in the golf support apparatus 1 may be provided with a water-repellent coat, which can be used with confidence even when the golf support apparatus 1 is wet due to unexpected heavy rain.
