[0001] The utility model relates to the technical field of motion capture, in particular to a tracker used for whole-body motion capture. Background Art

[0002] Motion capture is to set trackers on the key parts of moving objects. The motion capture system captures the position of the trackers, and then processes the data of three-dimensional space coordinates through computers. When the data is recognized by the computer, it can be applied in animation production, gait analysis, biomechanics and ergonomics.

[0003] Existing trackers are generally fixed to key parts by glue or straps, but due to the large amplitude of some movements, the tracker is prone to offset during the capture process, thus affecting the results of motion acquisition.
