Abstract

The invention discloses an optical motion capture data processing method based on a dynamic template. By establishing a motion characteristic database, an improved optical motion capture data processing method based on a rigid body is provided; and the method stresses on solving the problem that the rigid body structure is damaged during motion, and establishes a dynamic matched template through the motion characteristic database so as to effectively solve the problems of mismatching and error accumulation because the prior rigid body matching only uses a unique match template. By using the information retrieval of the motion characteristic database, the method automatically adjusts length error parameters of each rigid body during tracking and matching, and automatically finishes without manual intervention during processing; and single-frame data processing time consumption meets the real-time requirement of motion capture.

Description

technical field [0001] The present invention relates to optical human body motion capture scattered data processing, especially to eliminate the error accumulation problem in data processing caused by noise data and missing data. Background technique [0002] In recent years, with the advancement of computer software and hardware technology, Virtual-Reality (VR) technology has developed rapidly. The research on motion capture data processing is one of the important research fields of VR technology. The representation of geometric and behavioral characteristics in the generated space (virtual environment) mainly includes two main aspects: Facial Expression Simulation and Human Motion Synthesize. It is widely used in many industries such as industry, agriculture, transportation, culture, education, health and sports in the real world, especially in the fields of sports science research, sports training guidance, modern film and television, animation and game production. It has...
