Embodiment Construction
[0017] The present invention will be further described below in conjunction with drawings and embodiments.
[0018] A specific embodiment of the motion reconstruction method based on the sparse input signal of the present invention includes the following steps:
[0019] 1) Choose the free and open HDM05 action library as the source of the action database;
[0020] 2) Read all 216 action clip files into the action database, reorganize them in units of frames, and synthesize one frame based on the average value of every 4 consecutive frames, and obtain a total of about 260,000 frames, each with 93 dimensions action database;
[0021] 3) Calculate the corresponding position, rotation angle, rotation angular velocity and rotation angular acceleration of each frame respectively;
[0022] 5) An index structure based on a K-D tree is established for each frame of rotational angular acceleration data;
[0023] 6) In the online state, use the FAB inertial motion capture device to ob...
