Abstract: |
One of the key issues of the virtual studio based on the electromechanical tracking is camera calibration and initial alignment. This paper analyzes the structure and request of the virtual studio based on the electromechanical tracking, and proposes flexible methods to calibrate and align the camera in the virtual studio based on the electromechanical tracking. Both simulated experiments and the real data are used to verify the methods. The results demonstrate that the proposed methods is easy to manipulat and satisfy the needs of the virtual studio system. |
Keywords: virtual studio camera calibration camera alignment virtual reality electromechanical racking |
