Embodiment Construction
[0029] The preferred embodiments of the present invention will be described in detail below.
[0030] The present invention applies table tennis motion positioning technology and pressure sensor, wherein the table tennis positioning technology refers to the technology of calculating the real-time position of the table tennis ball during the movement through the existing Internet of Things device and positioning method; the pressure sensor deforms after being subjected to the pressure of the object to generate pressure sensory data. Such as figure 1 As shown, the Internet of Things components (such as signal strength positioning components, etc.) deployed in the table tennis system for table tennis positioning obtain table tennis position data, and the pressure sensor deployed on the racket surface obtains pressure sensing data. In the present invention, the hitting of the table tennis ball by the racket is divided into two situations of serving and returning the ball, and oth...

The invention discloses a positioning-based ping-pong battle service recognition system and method. The system comprises a module for obtaining pressure sensing data and judging whether a racket hitsa ping-pong ball or not, a module for reading the position and coordinates of the ping-pong ball and a module for judging whether the action of hitting the ping-pong ball through the racket is ball service or not. An internet-of-things assembly, such as a signal intensity positioning assembly, used for positioning the ping-pong ball is arranged in a ping-pong system to obtain ping-pong position data, and a pressure sensor is arranged on the surface of the racket to obtain pressure sensing data. The action of hitting the ping-pong ball through the racket indicates ball service and ball returning, and other ball hitting conditions except ping-pong battles are not considered. The ball needs to be thrown before ball service, the moving speed of the ping-pong ball is low, the moving speed of the ping-pong ball is high before ball returning, and a server judges whether the action of hitting the ping-pong ball through the racket is ball service or not on the basis. The system solves the problem that a ping-pong ball moving system based on the internet of things cannot easily and effectively recognize ping-pong battle service.
Description
technical field [0001] The invention belongs to the technical field of intelligent table tennis, and in particular relates to a positioning-based system and method for recognizing a serve in a game of table tennis. Background technique [0002] The existing table tennis sports system based on the Internet of Things mainly uses table tennis sports video or image analysis to identify the game's serve, and its disadvantages are high computational complexity and poor timeliness. To this end, a positioning-based system and method for identifying serve in a table tennis game is proposed. Contents of the invention [0003] The technical problem to be solved by the present invention is that the table tennis system based on the Internet of Things cannot simply and effectively identify the table tennis match serve, and proposes a positioning-based table tennis match serve recognition system and method. [0004] The present invention applies table tennis motion positioning technolog...
