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.
