Embodiment Construction

[0035] The preferred embodiments of the present invention will be described in detail below.

[0036] The present invention uses a pressure sensor, and the pressure sensor deforms after receiving the pressure of an object to generate pressure sensing data. Such as figure 1 As shown, the pressure sensors deployed on the table tennis table and the racket surface respectively acquire pressure sensing data, and then send it to the server, and the server recognizes the effective serve according to the characteristics of the effective serve during the table tennis game.

[0037] If the table tennis players are numbered as A and B, then the numbers of the table and racket are the numbers of the corresponding opponents; the pressure sensor is deployed on the table top of the ball, and the pressure sensing area covers the entire table; the pressure sensor is deployed on the surface of the racket, and the pressure The sensing area covers the entire racket face. The sampling time inter...

Abstract

The invention discloses a system and method for identifying effective ball serving during a pingpong competition on the basis of touch feedback. The system comprises a module for obtaining pressure sensing data and judging whether a pingpong ball collides with a table or not, a module for reading historical data and extracting the number of times that the pingpong ball is collided with a racket and collision moments, a module for judging whether the number of times that the pingpong ball is collided with the racket and the collision moments accord with effective ball serving features or not, and a module for judging whether the number of the racket collided with the pingpong ball accords with the effective ball serving features or not. Pressure sensors are distributed on the surface of thepingpong table and on the surface of the racket to obtain the pressure sensing data, then the pressure sensing data is sent to a server, and the server recognizes effective ball serving according toan effective ball serving rule during the pingpong competition. The system solves the problem that a pingpong sport system based on the internet of things cannot simply and effectively recognize effective ball serving during the pingpong competition.

Description

technical field [0001] The invention belongs to the technical field of intelligent table tennis, and in particular relates to a system and method for recognizing an effective serve during a game of table tennis based on tactile feedback. Background technique [0002] The existing table tennis sports system based on the Internet of Things uses table tennis sports video or image analysis to identify effective serves during the game, but the disadvantages are high computational complexity and poor timeliness. To this end, a system and method for effective serve recognition in table tennis games based on tactile feedback is proposed. Contents of the invention [0003] The technical problem to be solved by the present invention is that the table tennis sports system based on the Internet of Things cannot simply and effectively identify the effective serve during the table tennis game, and proposes an effective serve recognition system and method for the table tennis game based ...
