Description

[0001] The present invention relates to a golf swing analysis apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for analyzing a golf swing, and more particularly, to an apparatus for analyzing swing, swing type, shot type, swing tempo, and the like by analyzing a motion of a golf club.

Golf is a sport in which clubs strike the ball and reach the target point. To increase the distance of the ball in golf or to blow the ball in the desired direction, accurate hitting angles, striking points, striking strength and accurate swing trajectory are required. Especially, it is necessary to fly the stopped ball accurately. Therefore, the accuracy of impact including impact angle and impact point, impact strength, impact and swing trajectory must be harmonized so that the distance of the ball becomes long and the pitch is improved.

The golf swing can be roughly divided into drivers' long driving shots, short irons such as irons, and putting with putters. Although the swing is somewhat different depending on the club's choice, the most basic swing tricks are square impact (right angle strike) and flat swing trajectory close to the target line. With this hit, you can get a straight ball with a large distance that does not bend.

Many tools have been devised to correct golf swing, some of which are being used. These tools are used to diagnose the principle of golf swing using ancillary equipment and to prepare for actual swing. There are not many tools that can judge and correct in real swing. In general, a method of diagnosing a swing motion by using a tool is widely used in a high-speed video shooting by a video camera such as a camcorder, and a two-dimensional motion picture is obtained about a swing motion of a practitioner. And the swing motion of the practitioner is diagnosed and analyzed in comparison with the reference image of the standardized swing motion. This method requires expensive reading equipment such as expensive video shooting equipment, installation of shooting equipment, expensive software and coaches, and the practice is complicated and expensive.

The following Prior Art 1 relates to a swing speed training golf club for attaching a speed detecting sensor to a golf club head and a display means at a grip portion to display the maximum speed of the head. However, these tools are meant to indicate the maximum speed of the golf club head during swing and do not analyze the exact swing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

1 is a block diagram showing an internal configuration of a golf swing analysis apparatus according to the present invention.

In one embodiment of the golf swing analysis apparatus of the present invention, the swing sensing unit including at least one of the acceleration sensor and the gyro sensor, the microphone for sensing the sound and the acceleration information in the acceleration sensor, the angular velocity information in the gyro sensor, And a swing analyzer for analyzing swing and swing type using the received sound information.

The swing sensing unit includes an acceleration sensor and a gyro sensor for acquiring basic information for determining whether a swing occurs as a user uses the golf club. When the user swings the golf club, the golf club moves in the form of a kind of simple movement, so that the acceleration (speed) and the angular velocity (angle) are changed. In order to analyze the motion of the golf club, the swing sensing unit acquires velocity information and angle information through an acceleration sensor and a gyro sensor, and provides the information to the swing analysis unit.

The swing analyzer is configured to analyze the swing using the signal received from the swing detector. In the present invention, the swing, the type of swing, the type of shot, and the like are analyzed in various embodiments, and the details will be described later.

Since the golf swing basically follows the shape of the simple movement, the speed information and the angular information at the time of the golf swing reveal a clear pattern difference (usually, when swing, the speed, acceleration information, swing If not, a random velocity, acceleration information is obtained). Accordingly, the swing analyzing unit determines whether or not the swing is based on whether the speed / angle information that can be determined by the swing is acquired, and analyzes the type of the swing according to the pattern of the speed / angle information during the swing.

An example of determining the swing type and swing type in the swing analysis unit will be described in detail.

One golf swing is largely addressed (stopping the golf club near the golf ball and determining the swing), back swing (pulling the golf club backward after the address in preparation for applying force), downswing And a follow swing (an operation for pushing the ball forward after hitting the golf ball).

In order to determine whether a golf swing is to be performed and to analyze a swing type, it is first necessary to determine whether the current user's motion is taking an address action. At the address, the user takes action to stop the golf club for a predetermined time near the golf ball. That is, at the address, the velocity / angle of the golf club is maintained or the amount of change is kept below a certain threshold value. Therefore, the swing analyzer determines the speed / angle information received from the swing sensing unit as an address state when the speed / angle information does not change below a specific threshold for a predetermined time. In other words, if the acceleration information received by the acceleration sensor or the angular velocity information received by the gyro sensor does not fluctuate below a specific threshold for a certain period of time, it is judged as an address state.

It is determined whether the back swing operation and the down swing operation are performed subsequently. As described above, since the golf swing, particularly the back swing, the down swing, and the follow swing is a single-swing motion with the user's upper body as the central axis, depending on whether the speed / Down swing / follow swing. In addition, you can analyze the trajectory of each swing and analyze the swing tempo when combined with time information.

In one embodiment of the present invention, the velocity (acceleration) and angle information received from the swing sensing unit are analyzed to determine whether the golf ball is impacted (hit). Whether or not an impact is applied to the golf ball uses an instant change amount of the acceleration information or an instant change amount of the angular velocity information. To distinguish this, Fig. 3 will be described.

FIG. 3 is a graph showing an example of determining an impact occurrence in the swing analysis unit in the golf score device of the present invention.

3 shows the time-dependent output of the acceleration sensor after a downswing. It can be seen that the amount of change in the acceleration value in the x, y, z axis on the three-dimensional space is shown, and that the instantaneous change amount of the acceleration is approximately more than the specific threshold value in comparison with the other time periods. As the head of the golf club contacts the golf ball, the acceleration of the golf club changes during the process of transmitting the force due to the swing to the golf ball. Thus, it can be determined whether or not the impact has occurred. Based on this, you can distinguish between practice swing and actual swing. During the practice swing, the golf ball and the golf club are not in contact with each other, so the amount of acceleration variation is kept within a certain threshold range. That is, if it is determined that a swing is detected but no impact has occurred, it is determined that the swing is a practice swing.

Meanwhile, the present invention includes a microphone for sensing sound, and the swing analyzer can determine the occurrence of an impact using sound information received from the microphone. When a golf ball is hit, that is, when an impact is generated, a sound is generated as the golf club head and the golf ball hit each other. In this embodiment, the impact is detected by detecting a hit sound using a microphone. The golf swing analyzer according to the present invention detects a hit sound to determine whether the sound corresponds to the sound when the ball is hit, and analyzes the swing based on the determination.

This embodiment can be particularly useful for distinguishing whether the ball is correctly positioned or grounded. It is very important to hit the ball precisely during a golf swing, and many players, especially beginners, can hit the ground without a ball. In this case, if the swing is analyzed based only on the variation of the acceleration, there is a problem that the acceleration / angular velocity change over a specific threshold value is detected even when the ground is hit, so that the swing can not distinguish between the ball swing and the ground swing.

In the present invention, the sound is sensed by using the microphone and the swing is analyzed by using the swing. Thus, it is possible to determine whether the swing is accurate.

Meanwhile, in one embodiment of the present invention, the swing analyzer can classify types of shots by analyzing velocity information or angle information at the time of a backswing or a downswing, and an amount of change in acceleration at the time of impact. This embodiment will be described on the basis of FIG. FIG. 4 is a graph for explaining a method for distinguishing a putting and a shot in the swing analyzing unit in the golf swing analyzing apparatus of the present invention.

FIG. 4 is a graph for explaining a method for distinguishing a putting and a shot in the swing analyzing unit in the golf scoring apparatus according to the present invention. FIG. 4A is a graph briefly showing the movement of the golf club during putting, and FIG. 4B is a graph briefly showing the movement of the golf club when the shot.

If the shot is a kind of long-distance ball to send the golf ball near the green, the putt is the one to put the ball into the hole cup in the green. Therefore, the putting and the shot are distinguished by using the swing trajectory, the range, the acceleration information at the time of impact, and the amount of acceleration change.

The putting has a smaller angle of back swing, down swing, and follow swing than the shot, and the swing speed is also slower. On the other hand, the impact strength is weak. Therefore, in the present embodiment, when at least one of the speeds v1 and v2, the angular information? 1 and? 2, and the acceleration change amounts? A1 and? A2 detected during the swing of the user are less than preset values Putting is judged as a putting, and when it is more than that, it is judged as a shot.

In another embodiment of the present invention, the swing analyzer classifies the type of swing using the angle information of the club head when an impact occurs. This will be described on the basis of FIG.

FIGS. 5 and 6 are diagrams illustrating an example of classifying the swing using the golf swing analysis apparatus of the present invention. 5A to 5E show points at which an impact occurs between the golf ball and the golf club head.

In the course of a golf game, it is necessary to apply a backspin or forward spin to the ball or generate a left / right spin, considering the various factors such as the distance between the target point and the current point, and the topography. In order to analyze whether the balls are matched to respective needs, the swing analyzing unit in the embodiment of the present invention uses the angle information of the club when the impact occurs. The angle between the club head and the ground differs from the case where a point of a golf ball is aligned with the point of e, compared with a case where the ball is matched with a quiver (the impact is applied to the point c). This can be confirmed through FIG. 6 (a). The arrow indicates the direction in which the club head moves. 6 (a), 6 (a), 6 (c) and 6 (e) respectively show the movement of the club head when a, c and e in FIG. When a point is aligned, a forward spin occurs and a back spin occurs when the point e is aligned. On the other hand, in FIG. 6 (b), slices, rectangles, and hooks are generated depending on which of the center, left, and right sides of the ball are aligned (a slice is created when b is aligned with a right hand, and a hook is generated when d is aligned .) The impact of the point b, c, or d can also be detected using the angle information detected by the swing detection unit at the time of impact, so that the swing analysis unit can determine the type of swing.

Meanwhile, in an embodiment of the present invention, the swing analyzer can distinguish the swing by comparing the angle information in the address state with the angle information in the impact state. In this embodiment, it is possible to analyze whether or not the player has swung as intended.

The player places the golf club in the addressing operation in accordance with his / her desired swing. Therefore, when the address operation is performed, the angle information of the club head is compared with the angle information at the time of impact, and if it is within the error range, it can be determined that the swing has been performed as desired by the player. On the other hand, if the angle information between the address and the impact differs by more than a certain range, it can be judged that the swing can not be performed as desired. Therefore, the swing analyzer of the present invention can judge whether the ball is hit as well as distinguishing the type of swing by comparing the address state with the angle information at the time of impact.

In another embodiment of the present invention, the golf swing analyzer further includes a database in which the GPS sensor and the geographical information of the golf course are stored, and the swing analyzer compares the position information and the golf course position information received from the GPS sensor to determine the type of the shot .

The GPS sensor is a configuration for receiving position information and can acquire the current position (position information matched with the time information) of the user using the golf swing analysis apparatus.

The GPS sensor receives the GPS signal and transmits the current position information. The database stores the location information of the golf course. By providing the position information of the golf course to the swing analysis section, the swing analysis section combines the position information with the position information acquired from the GPS sensor so that the current position of the golf course The green of the hole, and a similar detailed location), and the type of shot can be determined based on this analysis. This embodiment will be described with reference to FIG.

2 is a diagram illustrating an example of analyzing shots by combining swing information and position information. Fig. 2 exemplarily shows one hole of a golf course, and A, B, C, and D indicate various positions in one hole. A is the tee box which is the starting point of the golf game, B, C is the fairway, D is the green, and the flag model shows the position of the hole cup.

The swing analysis unit analyzes the position information received from the GPS sensor and the golf course geographical information received from the database to determine the swing position at which the user swings in the golf course. Analyze the swing or putting, and the type of swing (tee shot, fairway shot, etc.).

For example, in FIG. 2, swing is performed at both the points A and B, while the swing at the point A is a tee shot and the swing at the point B is a fairway shot. When using acceleration, angular velocity, and sound information alone, it may be difficult to distinguish between a tee shot and a fairway shot. However, when the swing is analyzed by combining position information as in the present embodiment, the above shots can be distinguished . Shots at points C and D, ie, chip shots and putts, can be distinguished by the same method. That is, by analyzing the swing information in combination with the position information, it becomes possible to distinguish the types of shots in more detail and concretely.

In one embodiment of the present invention, the apparatus may further include a memory for storing at least one of swing analysis information, a type of shot, and a shot position. The memory stores a variety of information analyzed by the swing analysis unit, and is provided so that it can be used to restore the user's swing. In other words, it is possible to analyze what is recorded in a specific golf course or a specific hole by using accumulated data stored in the memory, and to analyze the distance, the accuracy of putting by each shot, and the swing tempo, swing The trajectory can also be restored. To this end, the memory can store the position information of the golf course and the data of each swing in association with each other.

In an embodiment of the present invention, the location analyzer may further include a position analyzer for analyzing the position information received from the GPS sensor and the golf course position information received from the database to calculate the distance.

It is one of the most important information about the distance of each shot in the golf game. In the present embodiment, the position information between consecutive shots is compared with the position information of the golf course to calculate how much distance each shot has recorded, how much distance to the target point (green) remains, and the like to the user can do. That is, according to the present embodiment, the apparatus of the present invention can replace the role of the caddy.

Meanwhile, in another embodiment of the present invention, the position analyzer may analyze the type of shot suitable for the user according to the current position information, the position information of the golf course, and the distance to the target point. By analyzing the distance from the fairway to the green, the mileage of each user stored in the memory, and the old information stored in the memory, This may be provided to the user.

According to an embodiment of the present invention, a communication unit for communicating with an external device may be further included. Thus, information analyzed / computed by the swing analysis unit, information stored in the memory, and the like can be transmitted to an external device. In an external device (such as a smart phone, a PC, or a server) Provide for systematic management. In addition, a file for updating the internal structure of the golf swing analysis apparatus can be transmitted and received through the communication unit.

In another embodiment of the present invention, an output unit may be further included. The output unit outputs a swing analysis result and the like of the swing analysis unit. The output unit can be implemented by a speaker (voice signal), a display (visual signal), and the like, and the form is not limited.

In one embodiment of the present invention, the user may further include an input unit capable of inputting golf club information to be used in the current shot, wherein the memory stores the inputted golf club information as at least one of the swing analysis information, Can be stored and matched with any one of them. Thus, the user can analyze and recreate his swing information and distance information for each golf club, and can analyze the position and time of the club during the golf game.

Meanwhile, the golf score device of the present invention is preferably manufactured to accurately collect and analyze information on the swing of the user. As an example thereof, the present invention can be applied to a club-type, a wrist band type, or an glove- .

FIG. 7 is a diagram illustrating an example in which a golf swing analysis apparatus of the present invention is worn by a user. The wrist band type is attached to the wrist in the form of a wristwatch, for example, to position the golf scoring device on the wrist, which serves as a rotation axis of the golf club, to obtain information necessary for the swing analysis. As another example, in the case of the glove detachable type, the golf scoring device may be detached and attached to a glove to be worn in a golf game using a velcro or the like. In the case of the glove detachable type, since the golf scoring device is attached to the outside of the wrist, the swing can be analyzed by reflecting the snap action of the wrist. On the other hand, the club-mounted type is advantageous in that it does not need to be attached directly to the user's wrist.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. You should see.
