CORRELATION EXTRACT METHOD FOR GENERATING 3D MOTION DATA, AND MOTION CAPTURE SYSTEM AND METHOD FOR EASY COMPOSITION OF HUMANOID CHARACTER ON REAL BACKGROUND IMAGE USING THE SAME

Provided are a method for extracting a correlation to generate 3D motion data, and a motion capture system and method using the extracting method to easily compose a humanoid character on a real background image. Cameras for motion capture are installed in a real background capture location (such as an outdoor location or in a studio), and the correlation between motion capture fixed cameras and a moving camera for capturing a real background image is obtained to capture 3D motion data prior to performing motion capture for integrating a humanoid character, so that even when there is interaction between a 3D figure and an actual prop such as a chair or table within the captured space, a humanoid character can easily be composed with the real background.
