Abstract
Multi-camera calibration parameters are needed in free-viewpoint video system to obtain virtual viewpoint. Most existing calibration technologies are for single camera and further research is needed for multi-camera calibration. A multi-camera calibration method based on 2D plane calibration algorithm combined with stereo vision calibration is proposed in this paper. Camera intrinsic parameters can be obtained using 2D plane calibration algorithm. Through transforming the world coordinate system, the unique extrinsic parameters are got. The validity of the proposed method is verified by experiments.
