Intelligent tennis racket teaching auxiliary system and method and tennis racket

Abstract

The invention relates to an intelligent tennis racket teaching auxiliary system. When the tennis racket hits a tennis ball, an acceleration sensor measures the real-time acceleration in the swing direction of the tennis racket, a gyroscope sensor measures the real-time angular velocity in the swing process of the tennis racket, a micro-controller module determines the real-time swing parameter value of the tennis racket according to the real-time acceleration value and the real-time angular velocity value and sends the real-time swing parameter value to a server, the server generates an effective movement track of the tennis racket according to the real-time racket swing parameter value in a preset time period and calculates a similarity value between the effective movement track and a standard movement track, and an exerciser continuously exercises to improve the similarity value so as to achieve the movement shaping of the exerciser. By means of the tennis racket, a tennis practicer can finish shaping of standard racket swinging actions, the tennis skills are improved, the injury phenomenon is avoided, and the tennis practicing interestingness is also improved. The invention further relates to an intelligent tennis racket teaching auxiliary method and a tennis racket.
