Abstract
Motion capture system has been used in various fields. At present, optical motion capture is most popular motion capture system. However, optical motion capture is often complex, costly and limited by the infrastructure itself. Here we propose to use stereo camera information and Inertial Measuring Units (IMU) to obtain a precise motion measurements at all time. The combination of the two systems thus overcomes the weaks point of each. On stereo camera information, we use optical flow and stereo processing. IMU data are obtained using coordinate transformation with correlation coefficient. Occlusion is resolved using correlation coefficient. To build a motion capture system using sensor fusion by these methods.
