The acquired measurement information is stored in the data storage unit 200 (S14).

The control unit 400 determines whether the number of swings of the user stored in the data storage unit 200 has reached the preset effective swing count (S16). The number of effective swings can be set appropriately for each user. For example, it can be automatically set in consideration of the user's mobility, average score, age, etc., and on the other hand, the user can directly set the number of times of recovery.

If it is determined in step S16 that the predetermined number of effective swings has been reached, the reference swing data calculated based on the measurement information belonging to the number of valid swings is set (S18).

The reference swing data is information on the swing trajectory, the position and direction of the head and the grip at important points of the swing trajectory, the speed when the backswing and the downswing are performed, and the like. In the swing data belonging to the effective swing count, Distance, direction, speed, and the like of the data.

The reference swing data is compared with the swing data of the professional golfer provided in the external data providing unit 250 (S20).

The control unit 400 determines whether the reference swing data and the swing data of the professional golfer are within a predetermined deviation range (S22). The predetermined deviation range may be an error range that can be calibrated by the user. For example, if the variation value of the trajectory, velocity, and posture generated when the user hits the ball using the same golf club is within a predetermined deviation range .

In step S22, if the reference swing data and the swing data of the professional golfer are within a preset deviation range, it is checked whether to continue the swing analysis (S24). If the swing analysis is not continuously performed, the use of the golf swing posture correction system is terminated.

In case of continuing the operation, it is checked again whether to reset the number of effective swings or the like and to change the setting (S26).

In the case of resetting again and changing the setting, the work for storing information corresponding to the number of effective swings is performed in the data storage unit 200.

On the other hand, when the reset is not proceeded, the swing information is continuously analyzed in a state in which the predetermined effective swing count is used as it is.

If it is determined in step S22 that the reference swing data and the swing data of the professional golfer are not within the preset deviation ranges, it is checked whether the swing analysis is continuously performed (S28). In the case of continuous progress, the swing information is continuously analyzed while using the predetermined effective swing count as it is. On the other hand, when the swing analysis is not continuously performed, the use of the golf swing posture correction system is terminated.

As described above, the golf swing posture correcting system using the swing motion of the screen golf user according to the present invention has the swing trajectory, the position and direction of the head and the grip at the important points of the swing trajectory, A process of comparing and analyzing the repeated swing data made by the screen golf user and the swing information data provided from the outside in a state in which the speed when performing the downswing is acquired by using a plurality of measurement sensors provided in the screen golf driving range To provide feedback to screen golf users.
