- Chessboard pattern is popular in most of state-of-the-art camera calibration toolboxes. However, because of its geo-metric symmetry, it results in ambiguous extrinsic parameters or requires manual intervention to select the correct corre-spondences of extracted corners in image. In this paper a deformed chessboard pat-tern is designed to automatically accom-plish camera calibration and metric recti-fication. We mainly utilize the cuboid bound of optical center to automatically obtain the correct correspondences of four extreme corners. The real experi-ments are shown to verify the correctness of the proposed technique.
