Problems solved by technology

The inertial tracking technology is characterized by simple implementation and strong anti-interference; the disadvantage is that it cannot fully obtain the motion characteristics of the tracked target, and can only reflect the motion characteristics of the tracked target limitedly and partially
The feature of optical tracking technology is that it can fully reflect the movement of objects with high precision; the disadvantage is that it is difficult to realize and the tracking range is small
The above-mentioned inventions only use one of the single technologies, the source of the technology is single, and the disadvantages are obvious.

Abstract

A tennis motion capturing and analyzing method is characterized by comprising the steps of binding a mark point and a tennis racket, installing a camera on the dead ahead of a motion area, wherein the camera is used for capturing images of a motion area and obtaining inertia parameters of motion of the tennis racket mark point, collecting a digital image of the tennis racket, inputting the digital image to a general-purpose computer, obtaining a digital video image of motion of the tennis racket, collecting the inertia parameters of the motion of the tennis racket mark point, resolving the collected inertia parameters and the digital video image, fusing data of multiple sensors, obtaining a motion mode of the tennis racket mark point, identifying a motion pattern according to the motion mode of the tennis racket mark point, and identifying and analyzing captured motions.

Description

technical field [0001] The invention belongs to the cross fields of computer image processing technology, motion capture analysis technology and virtual reality technology, and in particular relates to a tennis motion capture and analysis method. Background technique [0002] Currently, New Generation Co., Ltd. CN1662283 discloses a tennis game system, which includes a game machine connected to a television receiver via an AV cable and a racket-shaped input device that provides operation input to the game machine. The input device instructs the tennis player on the hitting side displayed on the monitor screen to play. At this time, the game processor included in the game machine calculates the predicted return position of the opposing tennis player, and compares the current position of the hitting side tennis player with the predicted returning position to determine whether the predicted returning position is on the hitting side tennis player. If the judging device judges t...
