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
First Claim
1. A motion capture system, comprising:
- a calibration frame for calibrating positions of a fixed camera for motion capture and a moving camera for capturing a real background;
a fixed camera for capturing the calibration frame and a background marker or a corner point in a real background, and movement of a moving subject;
a moving camera for moving and capturing the real background; and
a motion capture processor for generating 3D motion data that extracts and automatically integrates a geometric correlation of the fixed camera and the moving camera with the real background.

Abstract
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.

5. A method, comprising:
-
using a fixed camera for motion capture; capturing a real background using a moving camera; extracting a geometric correlation of the fixed camera and the moving camera; and using the extracted correlation to capture motion of a real moving subject and generate 3D motion data automatically integrating the captured motion with the real background. - View Dependent Claims (6, 7, 8, 9)
