摘要
多公共点坐标联测法对点数量及其分布要求高,文章介绍仅需两仪器间通视的球心拟合法和双面法,基于间接测量激光跟踪仪原点的原理实现狭小空间坐标联测。分析了两种方法在不同范围下坐标联测精度,实验结果表明:两仪器相距5m时,球心拟合法、双面法的平移参数精度均优于0.050mm,旋转角参数精度分别为0.7″和1.5″。
Multi-common point coordinate transformation method has high requirements on point′s number and spatial distribution.The spherical center fitting method and dual-face method,all based on indirectly measuring laser tracker′s origin,are used to achieve coordinate transformation.The coordinate transformation parameters accuracy of mentioned methods are analyzed in different spacing between laser trackers.Experimental results indicate when laser trackers are 5m apart,the translation parameter accuracy for spherical center fitting method and dual-face method both methods are less than 0.050mm and the rotation parameter accuracy are 0.7"and 1.5",respectively.
