Automatic serve system and method

Abstract

The invention provides an automatic serve system and method. The automatic serve system comprises a controlled serve unit which is arranged on one side of a court, an induction unit which is arranged inside the court and a control unit; the controlled service unit is used for serving a ball to an athlete based on a received launch angle range; the induction unit is used for inducing springback information of the ball after the athlete catches the ball; the control unit which is connected with the induction unit and the controlled serve unit is used for analyzing a corresponding launch angle range with the athlete ball catching error rate being higher than a preset threshold value based on a launch angle when the controlled serve unit serves the ball and the corresponding springback information, and transmitting the obtained launch angle range to the controlled serve unit. Accordingly, according to the automatic serve system, the corresponding launch angel range with the highest ball catching error rate is obtained by analyzing the ball return condition of the athlete, the controlled serve unit is controlled to place extra emphasis on ball serving angles, and accordingly a purpose of training a weak link of the athlete is achieved.

Description

technical field [0001] The invention relates to a control field, in particular to an automatic serving system and method. Background technique [0002] With the systematization of athlete training, the way of sparring has been changed from manual to ball machine, in order to achieve the purpose of high-intensity training of athletes. [0003] Existing automatic ball-serving machines, such as table tennis ball-serving machines etc., are based on mechanical random angles. Smarter ball machines are usually supplemented by cameras to identify the player's position and posture, and then control the speed and angle of the ball. [0004] Although the existing technology can control the serve according to the player's position and posture, it lacks data analysis on the player's return error rate, and similarly, it is impossible to optimize training for the player's weakness. [0005] In view of the continuous update of athletes' training needs, technicians need to improve the auto...
