A method and system for obtaining running distance of a tennis player

Abstract

The present invention relates to a method and a system for obtaining the running distance of a tennis player. The method includes the following steps: S0, taking the long side of the tennis court as the X axis, and taking the short side of the tennis court as the Y axis to establish Cartesian coordinate system; S1, the Bluetooth base station receives the broadcast signal of the Bluetooth positioning tag at the first frequency; S2, the positioning server analyzes the position of the Bluetooth positioning tag through the broadcast signal, and the position includes a tennis sphere Position and player position; S3, calculate the position difference between the tennis ball and the player according to the position, if the position difference is less than the first threshold, execute S4; S4, if the corresponding X-axis motion direction of the tennis ball changes, execute S5; S5, record the player's ball-catching position; S6, repeat steps S1-5, obtain the player's next player's ball-catching time and ball-catching position, and define the distance between the two ball-catching positions as the running distance.

Description

technical field [0001] The invention relates to the field of tennis, in particular to a method and a system for obtaining the running distance of a tennis player. Background technique [0002] Tennis is one of the ball sports. There are nets between the tennis courts. Both sides of the game occupy one side of the court. Players hit the ball with tennis rackets. [0003] Tennis players have a stable medium-speed sparring, hitting a medium-speed stable and varied shot, good control of the direction of the shot, and good control of the receiving and serving are important evaluations for evaluating whether a tennis player has an excellent level. Among them, the tennis player, through the control of the tennis ball, makes the opponent run the longer the distance between two more catches, the easier it is to exhaust the opponent's physical strength and improve the probability of winning. However, the traditional method of obtaining the running distance of an athlete is simple. Th...

Problems solved by technology

However, the traditional method of obtaining the running distance of athletes is single, and simply uses a high-speed camera to locate the athlete's two receiving positions to calculate the running distance. This method requires a lot of manpower, and the accuracy of the calculation results is low.
