On the other hand, golf is a sport that is rapidly becoming popular in Korea, and the number of people who enjoy golf is greatly increasing due to the influence of producing many excellent players around the world.

In general, golf is a game in which players compete for superiority and superiority in the number of strokes required until a player hits a golf ball using a golf club on a field called a field and puts it into a predetermined hole. It's an athletic game.

In particular, in golf, since the hitting at the moment of impact determines the direction and distance of the golf ball, the player's concentration and hitting accuracy determine victory or defeat, and the accuracy of hitting is greatly influenced by the player's golf swing motion. It is possible to obtain the desired direction and distance only by hitting accurately.

That is, before the golf swing, an address operation is performed to aim the directivity angle of the golf club head with respect to the golf ball. distance can be obtained.

Therefore, in order to learn the correct golf swing movement, golfers watch a golf game, observe the movements of professional players, or obtain information while watching golf instruction broadcasts, but there is a limit to improving golf skills only through theoretical learning.

Therefore, beginners who are new to golf need to receive direct instruction on the correct swing from a golf coach, and even experienced players should constantly train for an accurate golf swing based on the swing they have already learned. If it is learned, it is difficult for the golfer to recognize it and correct the posture.

Therefore, the present invention compares and analyzes the directivity angle of the club head with respect to the golf ball at address and the directivity angle of the club head with respect to the golf ball at impact during swing practice using a golf club to obtain swing information on whether the golf swing is accurate or not. We would like to propose a golf swing practice system that informs users and enables accurate swing practice without the guidance of a golf coach.
