立体视觉系统摄象机标定自动化

A New Method of Auto──Calibration for Stereo Vision System

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．

This method of auto-calibration based on passive vision, and its auto- calibration control is presented firstly. This method based on traditional method is used to obtain 3D coordinate of laser speckle with laser detection, to obtain 2D image coordinate with optimal inquiry algorithm, to resolute in projected matrix with linear least square method. The experiment result and the auto-calibration precision was provided at the same time.
