Golf training aid system and method thereof {SYSTEM SUPPPORTING GOLF PRACTICE AND METHOD THEREFOR}

The present invention relates to a golf practice assistance system for forming a correct swing motion during golf practice, and more particularly, to a golf practice assistance system and method for comparing and analyzing the swing position of the actual swing by setting the correct swing position It is about.

Golf, which was recognized as a high-end sport, is increasingly recognized as a popular sport and is recognized as a sport that helps a lot in physical and mental health. Golfers play 18 holes three or four rounds, depending on how the game is played, and the golfer with the lowest average overall score is the winner. Because of the many rounds, concentration, physical health, and accuracy are the winners. . Here, the accuracy is highly dependent on the golf swing posture, and the correct accuracy and flying distance can be achieved only by hitting the correct posture.

Therefore, the golfers watch the golf game to closely observe the golfer's posture to obtain the correct golf swing posture, or get information by watching the golf teaching broadcast provided through television. However, this method can not be directly compared to your swing posture, the effect is limited. The best way is to get direct guidance from a professional at the field where you practice golf, but this can be costly and inconvenient because you have to spend time with the specialist or wait a lot for guidance.

In order to solve this problem, devices have been developed to record and provide the swing posture of the exerciser during golf swing practice, or to provide a video recording of the swing posture of the professional golfer or expert along with the swing posture of the exerciser. come.

Golf exerciser using a conventional video is composed of a camera, a key control unit, a main control unit, a video recording device, a video output device divided into a main screen and an auxiliary screen, a money input device and a golf ball supply device have.

The exercise of the exerciser's swing is photographed through a camera, and the captured exerciser's image is recorded on the image recording apparatus under the control of the main controller and is output on the main screen of the image output apparatus.

On the other hand, if the exerciser inputs an operation command to the main control part through the key control unit in advance and selects a specific player and swing type to compare, the swing of the specific player previously stored in the video recording device is displayed on the auxiliary screen of the video output device. The operation is output to the comparison screen.

At this time, if the swing motion of the exerciser is displayed on the main screen for a certain time, the main screen is paused and the swing motion of a specific athlete is displayed on the auxiliary screen for a certain time. In this way, the swing motion of the exerciser and the swing motion of a specific athlete are sequentially displayed on the main screen and the sub screen at regular time intervals.

The conventional video golf exerciser helps the exerciser to have a correct swing posture by correcting his posture by comparing his swing motion with that of a specific player.

However, the conventional video golf exerciser is limited in the following points.

First, since the swing movements of the exerciser and the swing movements of a specific athlete are displayed at regular time intervals, the exerciser cannot easily compare at a glance. In order to solve this problem, even if the main and sub-screens display the swing movement of the exerciser and the swing of a specific athlete at the same time, it is not easy to see the difference between the two swing movements in the continuous motion video.

Second, there is a disadvantage that the swing motion of the exerciser and the swing motion of a specific player are not displayed in synchronization. In order for the practitioner to effectively compare his / her own swing motion and the swing motion of a specific player, a correspondence relationship must be established between his / her specific swing motion and the specific player's swing motion. However, the conventional video golf exerciser does not have this synchronization process.

The present invention has been proposed in order to solve the above problems, by clearly limiting the distinction operation of the swing during golf practice, facilitates the golfer to repeatedly reproduce and acquire the correct swing, and allows the trainer to teach golf It is an object of the present invention to provide a golf training assistance system and a method for making it convenient.

In addition, the server 30 displays the virtual lines 21a; 21b; 22; 23 that guide the swing trajectory of the user H. After the user H enters the turn at bat, the virtual line is displayed. When the display unit 21a; 21b; 22; 23 is displayed, the address posture may be corrected while observing the display unit 20. On the contrary, after the user H takes an address posture, the server 30 moves the virtual lines 21a; 21b; 22; 23 on the display unit 20 so as to fit the user H. It may be.

Meanwhile, the mobile device 130 may be used for swing photography. Like the photographing units 10a and 10b and the display unit 20 connected to the server 30, the mobile device 130 may include a mobile photographing unit 110 and a mobile display unit 120 to start swing photographing. .

The mobile device 130 communicates with the server 30 through a wireless communication network, and the swing image of the user H is photographed by the mobile photographing unit 110 and displayed on the mobile display unit 120. The server 30 displays the virtual lines 21a; 21b; 22; 23 on the mobile display unit 120 in response to a request of the mobile device 130.

2) swing posture shooting step (step S 200)

This step includes the step of photographing the swing posture of the user (H) by the photographing unit (10a; 10b; 110) to generate a video.

This step is a step in which the recorded swing image is recorded after all preparations are completed in the previous swing photographing preparation step (step S 100). When the captured swing image needs to be extracted as a still image according to each swing step, the server 30 stores the swing image of the user H and the server 30 stores the swing image. Synthesizing with imaginary lines 21a; 21b; 22; 23.

In addition, since the club of the user H moves when the user H swings, the club line 23 needs to be regenerated and displayed at regular time intervals.

3) Swing posture determination step (step S 300)

This step is divided into a step of determining the swing posture in real time while photographing the swing posture and a step of determining the swing posture by extracting a still image from the stored swing image after the swing is finished.

In the real-time determination step, the server 30 stores the relationship between the side lines 21a and 21b and the club line 23 and the relationship between the front line 22 and the club line 23 when the user swings. Computing the swing result information in real time with reference to a relationship table. The relationship table shows the lines and the positions where they are arranged in space. For example, at a particular point in time, two lines are conditioned to meet or abut vertically, and the relationship table is created according to this condition.

The swing result information stores a user's swing video, swing accuracy, and the like. The swing accuracy may be calculated using an image analysis technique to be described later.

The step of determining the swing posture by extracting a still image, the server 30 is the relationship between the side line (21a; 21b) and the club line 23 and the front line 22 and the club line ( Dividing the relationship of 23) into frames according to the stored relationship table, generating the virtual club line 23 extending from the rear of the club of the user H in the divided frame by the server 30; The server 30 calculates the swing result information with reference to the relationship table.

5A, 5B, and 5C are views illustrating an embodiment of a display unit swinging in a correct posture according to the golf practice method of the present invention.

5A-5C show each step of the correct swing posture in front and side with imaginary lines. The swing posture may be displayed on the display unit 20 (120). Preferably, the swing posture step may be divided into 10 steps. According to the swing postures shown in FIGS. 5A to 5C, the utilization of the golf training assistance system of the present invention can be maximized. For example, referring to step 2 of FIG. 5A, which represents the second stage of a correct swing, it is preferred that the club and sideline 21a nearly cross, and to step 3 of FIG. 5A, which represents the third stage of a correct swing. It is preferable that the extension line of the club line 23 intersect with the front line 22.

In addition, as a tool for analyzing the swing posture, it is possible to use a variety of image analysis techniques that can be applied. For example, in the case of a still image, the leg of the user H, the angle of the upper body, the shape of the arm, the angle of the club, and the like are recognized using conventional image recognition technology to extract data.

The extracted value can be processed in three ways. The first method sends a warning message or guides the posture correction if the user H has not set up the correct posture. In the second method, when the club of the user H moves, the data extracted in real time may be guided in real time with the swing of the user H. Motion pictures can also be analyzed using the technique of analyzing still images. That is, the still image analysis technique is applied after extracting a still image from a moving image at predetermined time intervals. Such a guide is also possible by the instructor, but more preferably it can be handled automatically by the server. The third method extracts the swing posture of the user H, which has already been taken, as a step-by-step image image, and analyzes the image by the image analysis technique to guide correction of the posture.

In the image recognition technology as described above, recognition efficiency may be further improved by using a mechanical learning model called a known support vector machine (hereinafter, referred to as SVM). The SVM is one of the machine learning methods mainly used in the field of image recognition, and extracts characteristic elements such as color, edge, and shape from an image and expresses it as a mathematical function. And, by repeating this function thousands of times to tens of thousands of times through the computer device, the computer device that executes this function to automatically analyze and grasp the shape of the image through the training through the mechanical iterative learning Methodology. As a machine learning method that can be used in the present invention in addition to the SVM, a known machine learning method such as ADA Boost algorithm, Bayesian Network, Neural Network, etc. may also be employed. .

The swing accuracy is calculated based on whether the swing is performed from the data calculated by applying the above analysis technique, if the swing is actually performed, and whether the accuracy at the time of swing is within the required range.

As described above, the relationship between the side lines 21a and 21b and the club line 23 or the relationship between the front line 22 and the club line 23 is generally stored in a database as a relationship table.

4) Swing result transmission step (step S 400)

In this step, the swing result information is transmitted to the display unit 20. In addition, the swing result information may be transmitted to the mobile device 140. The swing image of the user H may be transmitted with data about the swing accuracy calculated in the swing posture determination step (step S 300) or a counselor's advice message about the swing. The user H can effectively correct the swing by using the received image and data.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and it is common in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
