Real-time video based motion capture system based on color and edge distributions

This paper proposes a real-time, video based motion capture system using two video cameras. Since conventional video based motion capture systems use many video cameras and take a long time to deal with many video images, they cannot generate motion data in real time. On the other hand, the prototype system proposed uses a few video cameras, up to two, it employs a very simple motion-tracking method based on object color and edge distributions, and it takes video images of the person, e.g., x, y position of the hand, feet and head, and then it generates motion data of such body parts in real time. Especially using two video cameras, it generates 3D motion data in real time. This paper mainly describes its aspects as a real-time motion capture system for the tip parts of the human body, i.e., the hands, feet and head, and validates its usefulness by showing its virtual reality (VR) application examples.
