Research on design and recognition of color markers in motion capture system

The motion capture system based on visible light needs a kind of artificial marker which can be recognized efficiently. Designs of existing markers are mostly based on black and white texture features that apply to static recognition. This paper designs a color marker and its recognition methods. It can reduce time complexity and make motion capture system based on visible light possible. We experimented on different sizes and postures, illumination conditions, image resolutions, to analyze factors that influence on recognition of color marker.
