Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
According to an aspect of an embodiment of the present invention, a distance display method is provided, which is applied to a terminal. In the embodiment of the present invention, the terminal includes, but is not limited to, a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, a pedometer, and the like.
As shown in fig. 1, the distance display method includes:
step 101: a first input by a user of a first geographic location and a second geographic location in a map screenshot is received.
The map screenshot is obtained by screenshot of a map displayed in map application software. The map screenshot may be a screenshot shared by other terminals, that is, before receiving a first input of a user on a first geographic position and a second geographic position in the map screenshot, the method further includes: receiving the map screenshot sent by other terminals; or the user can capture a screenshot of the map displayed in the map application software through the terminal.
The first input described herein is a trigger operation for displaying a straight-line distance between two geographic locations. The first input includes, but is not limited to: at least one of a pressing operation, a sliding operation, and a clicking operation.
Step 102: in response to the first input in step 101, a straight-line distance from the first geographic location to the second geographic location is determined according to the geographic distance information corresponding to the single density independent pixel.
The geographic distance information corresponding to a single Density independent pixel (Density independent pixel) herein refers to an actual geographic distance corresponding to a Density independent pixel, for example, the actual geographic distance corresponding to a Density independent pixel is 100 m.
The geographical distance information corresponding to the single density-independent pixel is obtained by calculation according to the scale information of the map displayed in the map application software in screenshot and the size information of the map screenshot. After the geographic distance information corresponding to the single density-independent pixel is obtained through calculation, the geographic distance information corresponding to the single density-independent pixel can be stored in additional information of the map screenshot, for example, in an Exchangeable image file format (Exif for short) of the map screenshot, the geographic distance information corresponding to the single density-independent pixel is concentrated in a certain designated field.
The density-independent pixels are independent of the resolution of the terminal screen and the screen density, the universality is good, and the calculated linear distance is more accurate.
Step 103: the straight-line distance from the first geographic location to the second geographic location is displayed in the map screenshot.
In this step, the linear distance from the first geographic position to the second geographic position determined in step 102 is displayed in the map screenshot for the user to view.
In the embodiment of the invention, a user can directly perform touch operation on any two places on the map screenshot, so that the distance between the two places can be quickly acquired on the map screenshot, and therefore, firstly, a distance measuring tool is not needed to be used for acquiring the linear distance between the two places, and the trouble of finding the entrance of the distance measuring tool is avoided; secondly, after the user does not need to manually input two places, the linear distance between the two places is obtained through route planning, and the threshold height is reduced; thirdly, after the map screenshot is obtained, the use of map application software can be reduced, and the electric energy consumed by starting a GPS function in the map application software is reduced; and fourthly, when the screenshot is shared by other users, the linear distance between any two geographic positions on the screenshot can be obtained even if no map application software is installed on the terminals of the other users, and the screenshot is convenient for the users to use.
For example, when a user views commuting information near a destination, the user wants to know information such as a subway station, a bus station, or an obvious landmark building near the destination. The user can quickly know the linear distance between two points near the destination (for example, a building at the destination and a nearby subway station) through the method provided by the embodiment of the invention so as to assist in judging the destination, and what commuting mode needs to be selected after the user leaves the subway station, and then the user can select walking, riding a bicycle, getting on the bus, and the like, thereby greatly facilitating the use of the map by the user.
To better understand the first input operation provided by the embodiments of the present invention, the embodiments of the present invention provide two embodiments, as follows:
example one
As shown in fig. 2, this embodiment includes:
step 201: and receiving the simultaneous pressing operation of the first geographical position and the second geographical position by the user.
In the first embodiment, the first input is a pressing operation performed on the first geographical location and the second geographical location together.
Step 202: in response to the pressing operation in step 201, when the pressing operation continues for a preset duration, determining a linear distance from the first geographic location to the second geographic location according to the geographic distance information corresponding to the single density-independent pixel.
In this step, the terminal starts timing after receiving a pressing operation performed by a user on both the first geographic position and the second geographic position in the map screenshot, and determines a linear distance from the first geographic position to the second geographic position according to the geographic distance information corresponding to the single density-independent pixel when the pressing operation lasts for a preset duration.
Step 203: the straight-line distance from the first geographic location to the second geographic location is displayed in the map screenshot.
For example, as shown in fig. 3, point a in the diagram corresponds to a first geographic location, and point B in the diagram corresponds to a second geographic location. When a user wants to view A, B the straight-line distance between two points, the user can press point a with a touch control body (such as a finger, a touch control pen, etc.), then press point B with a touch control body (such as a finger, a touch control pen, etc.), start timing when both points A, B are pressed, determine the straight-line distance from the first geographic position to the second geographic position when the pressing operation lasts for a preset time (such as 2 seconds), and mark and display the straight-line distance from the first geographic position to the second geographic position in the map screenshot. It will of course be appreciated that it is also possible to press A, B two points at the same time.
In the first embodiment, the distance between the two places can be obtained by clicking the two places simultaneously, and the operation is simple and convenient.
Example two
As shown in fig. 4, this embodiment includes:
step 401: and receiving a sliding operation of the user on the map screenshot.
In the second embodiment, the first input is a sliding operation performed on the first geographic position and the second geographic position. The starting point of the sliding operation is a first geographic position, and the end point of the sliding operation is a second geographic position.
Step 402: in response to the sliding operation in step 401, a straight-line distance from the first geographic position to the second geographic position is determined according to the geographic distance information corresponding to the single density-independent pixel.
In step 402, when the terminal receives the sliding operation with the starting point as the first geographic position and the ending point as the second geographic position, the terminal determines the linear distance from the first geographic position to the second geographic position according to the geographic distance information corresponding to the single density-independent pixel.
Step 403: the straight-line distance from the first geographic location to the second geographic location is displayed in the map screenshot.
For example, as shown in fig. 5, point a in the diagram corresponds to a first geographic location, and point B in the diagram corresponds to a second geographic location. When a user wants to view A, B the straight-line distance between two points, the user may touch point a with a touch object (e.g., a finger, a stylus, etc.), then control the touch object to move toward point B, lift the touch object when the touch object touches point B, determine the straight-line distance from the first geographic location to the second geographic location, and then mark and display the straight-line distance from the first geographic location to the second geographic location in the map screenshot.
Optionally, when A, B two points are not displayed on the current screen simultaneously (e.g. point a is displayed on the current screen and point B is not displayed on the current screen), for example, when the user performs A, B two-point touch more accurately, the map screenshot may be displayed in an enlarged manner, at this time, part of the map screenshot may not be displayed on the current screen, at this time, the touch object may be controlled to move towards point B, when the touch object moves to the edge of the screen, the map screenshot may move along the direction opposite to the direction of movement of the touch object, and when point B is displayed, the user controls the touch object to move to point B again, so that the viewing of the straight-line distance may be made without being limited to the range visible on the current screen, and the range of the distance measurement may be extended. Alternatively, in this case, when the straight-line distance is displayed, the map screenshot may be reduced to display A, B at the same time, and then the straight-line distance between A, B points may be marked and displayed.
Optionally, during the sliding process of the touch body, a connection line may be displayed, so that the connection line connects the first geographic position and the end position of the sliding operation.
For example, as shown in fig. 5, a connecting line 401 (a solid line or a dashed line) may be drawn with point a as a starting point, connecting point a and the end of the touch object sliding (i.e. the end position of the moving end of the sliding operation) to show the association between the two points.
In the second embodiment, two places for calculating the linear distance are selected through the starting point and the terminal of the sliding operation, the operation is simple and convenient, the linear distance can be checked without being limited in the range visible by the current screen, and the range of distance measurement is expanded.
Optionally, before the receiving a first input of a first geographical location and a second geographical location in the map screenshot by the user, the method further comprises: receiving screenshot operation of a user; responding to the screenshot operation, and carrying out screenshot on the map displayed in the map application software to obtain the map screenshot; determining geographical distance information corresponding to a single density-independent pixel in the map screenshot according to the scale information of the displayed map and the size information of the map screenshot; and adding the geographical distance information corresponding to the single density-independent pixel to the additional information of the map screenshot.
In the embodiment of the invention, when the terminal detects the screenshot operation, whether the application software running in the foreground is the map application software can be judged firstly, and the judgment can be specifically carried out through the package name of the application software or the image recognition technology. When the application software running in the foreground is map application software, screenshot is carried out on a map displayed in the map application software, and meanwhile, the scale information of the current map is obtained. And then, carrying out data conversion through the obtained scale information and the size information of the screenshot to obtain the geographical distance information corresponding to the single density irrelevant pixel, and adding the geographical distance information corresponding to the single density irrelevant pixel into the additional information of the screenshot. When the straight-line distance from the first geographical position to the second geographical position is displayed in the screenshot according to the first input, the straight-line distance from the first geographical position to the second geographical position in the screenshot can be determined and displayed according to the geographical distance information corresponding to the single density-independent pixel.
Optionally, in the embodiment of the present invention, when a map in the map application software is subjected to screenshot, a manner for user interaction may be provided to obtain the map scale information. When screenshot is carried out, if the application software running on the current foreground is judged to be map application software, the system pops up similar prompt information such as 'whether map information is detected at present and scale information needs to be acquired' for selection of a user, and after the user confirms that the scale information is acquired, a pop-up interactive frame is popped up for the user to select and store the scale information.
In the embodiment of the invention, in order to avoid the influence of different screen resolutions and screen densities, the geographical distance information corresponding to the single density independent pixel is calculated. The specific calculation method is as follows:
first, the related concepts will be explained as shown in table 1.
TABLE 1
Take scale information as an example, 1cm on the map represents a distance of 200 meters. First, the number of pixels a included in 1cm on the screen is calculated, where a is dpi/2.54(1 inch is 2.54cm), the number of dps included in 1cm is b, which is obtained from px is dp similarity, and b is a/similarity, which is a actual distance c indicated by a single dp pixel is 200/b (actual distance represented by 1 cm/number of dps included in 1cm on the screen).
Optionally, in response to the first input, determining a straight-line distance from the first geographic location to the second geographic location according to the geographic distance information corresponding to the single density-independent pixel includes:
in response to a first input, determining a density-independent number of pixels between an image corresponding to a first geographic location and an image corresponding to a second geographic location; and determining the straight-line distance from the first geographical position to the second geographical position according to the geographical distance information corresponding to the single density-independent pixel and the density-independent pixel number between the image corresponding to the first geographical position and the image corresponding to the second geographical position.
Suppose that the coordinates of the image corresponding to the first geographical position are A (x1, y1), and the coordinates of the image corresponding to the second geographical position are B (x2, y2), wherein the coordinates of the image are the coordinates of the center point of the image, and the unit of the coordinates is pixel px.
First, from the coordinates of A, B two points, the density-independent pixel (unit dp) distance d1 between A, B two points is calculated. Wherein the number of pixels between two points can be calculated A, B according to Pythagorean theorem
Then, the number D of pixels is converted into the number D1 of dp, that is, the density-independent pixel distance D1 between two points A, B is obtained, D1 is D/density, then, the geographic distance value c corresponding to a single dp pixel is obtained from screenshot additional information (such as information of a specified field in Exif), and finally, the straight-line distance D between two points A, B is obtained, that is, D1 is obtained.
In summary, in the embodiment of the present invention, a user can directly perform touch operations on any two locations on a map screenshot, so as to quickly obtain a distance between the two locations on the map screenshot, and thus, firstly, a distance measurement tool is not needed to be used to obtain a linear distance between the two locations, and a trouble of finding an entrance of the distance measurement tool is omitted; secondly, after the user does not need to manually input two places, the linear distance between the two places is obtained through route planning, and the threshold height is reduced; thirdly, after the map screenshot is obtained, the use of map application software can be reduced, and the electric energy consumed by starting a GPS function in the map application software is reduced; and fourthly, when the screenshot is shared by other users, the linear distance between any two geographic positions on the screenshot can be obtained even if no map application software is installed on the terminals of the other users, and the screenshot is convenient for the users to use.
