Motion capture involves measuring an object's position and orientation in physical space, then recording that information in a computer-usable form. Optical motion capture systems are based on high contrast video imaging of retro-reflective markers, which are attached to the object whose motion is being recorded. Optical systems are the most expensive of the motion capture systems. The operational costs are also higher, being more similar to film or video production. Tracking time can be much greater than the actual capture session and may vary unpredictably, depending on accuracy requirements, motion difficulty, and the quality of the raw data captured. In spite of these disadvantages, several vendors have released commercial optical motion capture systems for computer animation, because it generates quite realistic data.
The key issue of optical motion capture is the development of effective marker tracking algorithm and the manually tracking post-processing system. We developed an optical motion capture post-processing system for tracking lost markers easily. For an easy work we proposed stereoscopic display on 3D markers viewer. The effect of stereoscopic display in post-processing system gives view independent and easy manual tracking work
