讨论了基于被动视觉的摄象机标定方法，并完全实现了自动控制．该方法在传统标定方法基础上，以激光探测手段获取场景点（激光斑点）的三维坐标（３Ｄ）；以三步优化查询算法得到该场景点图象坐标（ ２Ｄ）；采用线性最小二乘算法求解摄象机透视投影矩阵．同时介绍了实验系统，给出了实验结果和精度． The method of camera calibration based on passive vision is discussed, and the automatic control is fully realized. Based on the traditional calibration method, the three-dimensional coordinates (3D) of the scene spot (laser spot) are obtained by laser detection. The image coordinates (2D) of the scene spot are obtained by the three-step optimization query algorithm. The linear least squares Solve the camera perspective projection matrix. At the same time, the experimental system is introduced and the experimental results and precision are given.
