specific Embodiment approach
[0060] First, preprocess the large-capacity motion database, perform feature extraction and segmentation for each motion data, and construct a motion index, and then perform intuitive and efficient 3D human motion data retrieval based on demonstration performances according to the process, see image 3 . Connect the motion sensor, set its global reference coordinate system, and input the standard 3D human skeleton, see figure 1 (a), if the user only pays attention to local body movements, such as the movement of the upper body, only need to select 5 feature nodes of the chest, left elbow, right elbow, left wrist, and right wrist, and use 5 motion sensors to obtain demonstration performance movements of the upper body , specify the corresponding relationship between the motion sensor and joint points through program interface interaction or input configuration files, and then place the motion sensor on the corresponding parts of the human body, seefigure 1 (b), after pose align...
