Scoring system and method for ball-hitting sports

Abstract

The invention discloses a scoring system for ball-hitting sports. The system comprises a microphone array module, a positioning module, a collision type classification module and a scoring module. Themicrophone array module is provided with two or more microphones and used for collecting a voice signal of collision of balls and different planes during ball sports and conducting voice recording; the positioning module extracts the time difference of the voice signal reaching different microphones and a reaching angle of the voice signal according to the voice signal collected by a microphone array, and accordingly the balls are positioned in real time; the collision type classification module is used for identifying the collision type of the balls and the planes through a classification method; the scoring module is used for conducing scoring on the game process according to the rule of the ball-hitting sports, collision type identification and ball positions. The invention further correspondingly discloses a scoring method of the system. According to the system, through the time difference of collision voice reaching the microphones, the positions of the balls are calculated, thetracks of the balls are recorded, the scores of athletes are distinguished by distinguishing different kinds of collision sound, and the aims of motion track recording and scoring are achieved.

Description

technical field [0001] The invention relates to the field of sound information processing, in particular to a scoring system and scoring method for batting sports. Background technique [0002] Most batting sports are internationally recognized sports, such as table tennis. The basic rules of the game are to separate the two ends of the table by counting the ball, and then the two sides take turns to serve the ball to the other side. and the opponent's two desktops, to return the ball, you need to wait for the ping pong ball to touch your own table, and then hit the table tennis back to the opponent's table. First to reach twenty-one points wins. In addition, there are other rules in the table tennis game. For example, if the serve touches the net to complete, it needs to be re-served. The two sides take turns serving five balls. Aforesaid table tennis only needs to set up a ball net with appropriate height between two ball table tops, and then each player holds a racket, ...

Problems solved by technology

[0003] At present, scoring in table tennis is mainly done by a number of referees visually watching the game process, and then scoring and displaying the visual observations. The above-mentioned table tennis scoring method has been followed for a long time. More, and the objectivity of human judgment is still insufficient, especially in normal practice, there is often a lack of referees. At this time, only the players can score by themselves. This scoring method is easy to affect the game due to subjective judgment. Moreover, if the scoreboard is used for scoring, it is time-consuming and will interrupt the game, so it is not ideal. If the score is scored by memory, it is troublesome and prone to forgetting and miscalculation.

[0004] At present, the trajectory of the table tennis ball is mainly recorded by the camera. This recording method is expensive and requires image processing technology to obtain the trajectory of the ball, which requires a large amount of calculation.
