In general, golf is recognized as an exercise that helps a lot for physical and mental health and is in the spotlight, and recently, as a popular exercise that has exponentially formed a large number of enthusiasts, the game of golf is 18 depending on how the game is operated. The hole is played in 3 or 4 rounds, and the golfer with the lowest number of strokes by combining these results is the winner.

However, as mentioned above, since golf rounds many holes, victory or defeat tends to depend on the concentration and physical health of the golfers, and the accuracy of the swing. , The desired distance and accuracy can be obtained only when an effective impact is applied in the correct posture.

That is, when the golfer swings, if the impact position applied by the golfer deviates from the position at which the golf ball is struck, the golf ball cannot be hit with the maximum force, so the flying distance is reduced and the accuracy is significantly reduced.

Accordingly, many golfers make great efforts such as lessons, video viewing, and filming to correct their swing posture in order to obtain better results according to their individual needs, but it is very difficult to understand the exact position of impact performed by the golfer. Because it was difficult, it was not possible to obtain satisfactory results for the time or cost invested.

Recently, efforts are being made to analyze one's swing pattern through various types of swing analysis devices, and swing information such as the speed of the batted ball, swing speed, and swing trajectory can be checked through equipment located on the screen golf course.

However, the screen-type swing analysis device as described above requires a large space, and there was a disadvantage in that it was not possible to analyze the swing in real time while actually playing on the golf course. There were time and financial difficulties as they had to visit the

In this case, the input unit 240 is provided in the form of a slide bar and a jog shuttle indicating the playback timing of the analyzed image, and may receive a playback control command capable of adjusting the playback timing back and forth and playing it back.

Through the analysis video, the user can visually recognize the impact timing, swing trajectory (movement of the swing axis), and power for each swing section, which are the moments when the effort is strongest during the swing, and correct the swing motion based on the swing timing guide. can go

6 is a diagram illustrating an analysis image for self-correction according to an embodiment of the present invention. Referring to FIG. 6, the analysis image 70 includes an image reproduction area 71 in which a reproduced image is displayed, a club type selection area 72, a swing trajectory 74 analyzed based on the body axis 73 in the reproduced image, It may include a swing timing guide 75 , an impact timing 76 , and a slide bar 77 provided based on the body axis 73 of the reproduced image corresponding to the specific club type selected in the club type selection area 72 . .

The server 300 may analyze the swing trajectory 74 through the received swing information to provide a swing trajectory corresponding to the time at which it is reproduced, and may display the impact timing 76 so that it can be recognized. In addition, the user can check the analyzed image by adjusting the playback time by using the slide bar 77 or a separately provided jog shuttle tool.

At this time, when a specific club type is selected in the club type selection area 72 , the server 300 provides a swing timing guide according to the corresponding club type, but sets the impact timing to 100% of the swing power and sets each swing section on the swing trajectory. By providing the swing power value, the user can intuitively recognize the impact timing and swing motion can be corrected.

As such, in the swing self-correction system according to an embodiment of the present invention, the user can visually check the difference between the impact zone and the swing zone in real time, so that the user can intuitively analyze the actual swing and perform self-correction. Accordingly, the batted ball flying distance may be increased and the frequency of occurrence of a miss shot may be minimized.
