Method and system for obtaining running distance of tennis player

Abstract

The invention relates to a method and system for obtaining the running distance of a tennis player. The method comprises the following steps that S0, establishing a rectangular coordinate system with the long side of a tennis court as the X axis and the short side of the tennis court as the Y axis; S1, the Bluetooth base station receiving a broadcast signal of the Bluetooth positioning tag at a first frequency; S2, the positioning server analyzing the position of the Bluetooth positioning tag through the broadcast signal, wherein the position comprises the position of a tennis ball body and the position of an athlete; S3, calculating the position difference between the tennis ball body and the athlete according to the position, and if the position difference is smaller than a first threshold value, executing S4; S4, if the corresponding X-axis movement direction of the tennis ball body is changed, executing S5; S5, recording the ball catching position of the athlete; and S6, repeating the steps S1-5, obtaining the ball receiving moment and the ball receiving position of the next sportsman of the sportsman, and defining the distance between the two ball receiving positions as the running distance.

Description

technical field [0001] The invention relates to the field of tennis, in particular to a method and system for obtaining running distance of a tennis player. Background technique [0002] Tennis is one of the ball games. The tennis court has a net at intervals. The two sides of the game each occupy one side of the court. The players hit the ball with a tennis racket. [0003] Tennis players have stable medium-speed sparring, medium-speed stable and varied shots, good control of the direction of the shot, good control of receiving and serving, etc. are important evaluations to evaluate whether a tennis player has an excellent level. Among them, through the control of the tennis ball, the tennis player makes the opponent's running distance between two catches the greater, the easier it is to exhaust the opponent's physical strength and thus improve the probability of winning. However, the traditional method of obtaining the athlete's running distance is single, and simply uses...
