Abstract

The invention provides a physical education teaching auxiliary system based on a motion identification technology and an implementation method of the physical education teaching auxiliary system. The system is applicable to a personal computer (PC) or an embedded host. The system comprises a movement data collection module, a movement data acquisition module, an identification and training module and a virtual teaching environment module. The device is characterized in that: a micro-inertia measurement unit and an inertia parameter extraction unit are arranged in the movement data collection module; and a movement information resolving unit transmits data which is output by the inertia parameter extraction unit to a multi-sensor data fusion unit for resolving. The movement situation of a target is reflected comprehensively in an inertia tracking mode and an optical tracking mode, so a tracking range is effectively expanded, measurement accuracy is improved, and the problems that the integral information of the target cannot be acquired in the inertia tracking mode, complicated movement identification cannot be performed and sensitivity is poor are solved. A brand new teaching mode is provided for physical education teaching, and a physical education teaching method is digitalized, multi-media and scientifically standardized.

Description

technical field [0001] The invention relates to the fields of human-computer interaction, action recognition and computer-assisted teaching, in particular to a construction method of a physical education teaching auxiliary system. Background technique [0002] At present, the methods of motion tracking are divided into: inertial tracking, optical tracking, force and mechanical tracking, electromagnetic tracking, acoustic tracking and so on according to different sensing elements. At present, the commonly used motion tracking technologies in the field of human-computer interaction are inertial tracking technology and optical tracking technology. Inertial tracking technology, by setting an inertial measurement unit on the target to measure data such as acceleration and angular velocity, based on this, use mathematical tools to solve the problem and obtain the motion of the target. The characteristics of inertial tracking are simple implementation and strong anti-interference;...
