Mixed motion capture system and method
A mixed system for capturing motions of an object and its use method is disclosed. The mixed system includes at least one inertial sensor module and at least one optical marker mounted on the object, and at least two optical cameras. Each inertial sensor module measures inertial information and spatial attitude information, and each optical camera captures image information of the at least one optical marker. Based on the collected information, a receiving processor respectively generates inertia-based position information and optics-based position information, and further integrates the above information to obtain position information of the object. Integration may involve assignments of different weights to the inertia-based position information and the optics-based position information based on respective measurement errors of the at least one optical marker and the at least one inertial sensor module. The inertia-based position information may be corrected based on biomechanical constraints and/or external constraints.
