为了保证立体视觉系统形状恢复的测量精度，提出了一种新的高精度标定方法。从感兴趣对象获取的一些标准点被用作标准世界点。有四个旋转矩阵和平移矩阵需要校准，第一个是左摄像机和世界坐标之间，第二个是右摄像机和世界坐标之间，第三个是左摄像机和右摄像机之间，最后一个是右摄像机和左摄像机之间。透镜畸变参数包括径向畸变和切向畸变。该标定方法具有精度高、操作简便、可靠性高等优点。
In order to ensure the measurement precision for shape recovery from a stereo vision system, a novel high precision calibration method is presented. Some standard points acquired from the object of interest are used as standard world points. There are four rotation matrices and translation matrices that need to be calibrated, the first is between the left camera and the world coordinate, the second is between the right camera and the world coordinate, the third is between the left camera and the right camera, and the last is between the right camera and the left camera. The lens distortion parameters include radial and tangential distortion. The merits of the calibration method are its high precision, easy of operation, and high reliability.
