Research on the Auxiliary Training System of Tai Chi Fitness Qigong Based on Computer 3D Image Vision Technology

Based on Kinect motion capture technology, this paper developed a set of auxiliary teaching software suitable for Tai Chi practice in view of the movement requirements of beginners. This teaching system can show students the standard moves of Tai Chi. A Kinect software system based on motion capture technology is established to realize the standardized measurement of motion capture. The collected data are filtered and de-nosed and stored to form a standard motion database. By collecting the data of the subjects' tai chi movement process, the subjects' movement process is presented in the form of color images in the interface window. The bone data is corresponding to the color image, and the key nodes in the image are identified. After the two sets of data are collected, the Dynamic Time Wide (DTW) method is used to deal with the corresponding frame matching problem. By assigning the rotation information of the connection points to the corresponding Unity3D human body model. Experiments show that the method adopts motion capture technology, DTW and other methods, and has been effectively coordinated with Unity3 3D simulation software for practice and scoring.
