MIXED MOTION CAPTURING SYSTEM AND METHOD

摘要

A mixed motion capturing system and method. The mixed motion capturing system comprises at least one inertial sensor module (101), at least one optical marker (102), at least two optical cameras (103), and a reception processor (104). The inertial sensor module (101) is connected to the reception processor (104), the optical cameras (103) are connected to the reception processor (104), and the inertial sensor module (101) and the optical marker (102) are installed on an object to be measured. The inertial sensor module (101) measures inertia information and space attitude information; the optical cameras (103) acquire image information of the optical marker (102); the reception processor (104) generates inertia-based position information according to the inertia information and the space attitude information, generates optical marker point-based position information according to the image information, and integrates the inertia-based position information with the optical marker point-based position information, so as to generate position information of the object to be measured. The mixed motion capturing system combines advantages of optics-based motion capture and advantages of inertia-based motion capture, and can avoid disadvantages of the two motion capturing modes at the same.
