摘　　要：针对光学三角测量中物距、像距及系统结构参数间的非线性关系 ,本文通过设置辅助变量及组合参数 ,使变量间关系线性化 ,然后根据实测数据采用最小二乘法拟合出组合参数的准确值 。The relation among the object distance, image distance and system construction parameters is nonlinear in optical triangulation. In order to linearize the relation auxiliary variables and composite parameters are set in this paper. Then these parameters can be approximated with least square method, as a consequence the large scale laser range system can be calibrated accurately.
