Design of Motion Capture System Based on MEMS.

In sports training, the optical motion capture is limited by complex data processing equipment, space constraints and other issues. This paper presents a design of motion capture system based on MEMS. The system includes the target module and PC module. The former is used to collect human motion information with MEMS sensors, and uploads data to the host computer. The later reproduces human movements in real time by building a virtual mannequin with VTK. Experimental results show that this method can effectively reproduce human motion with the error in 1 degree.
