Leica AT960激光跟踪仪测量精度分析

Precision Analysis of Leica AT960 Absolute Laser Tracker

以Leica AT960激光跟踪仪为例,在分析其测量基本原理的基础上,结合国内外测量精度分析方法,对激光跟踪仪的测角精度、测距精度、激光相对于靶球入射角对精度的影响以及环境因素引入的测量误差分别进行了详细的实验分析,并对激光跟踪仪现场测量的点位坐标进行了测试。实验结果表明,激光跟踪仪的各项测量精度均符合其标称精度,其测量结果具有较高可靠性。

Taking Leica AT960 as an example,this paper first analyzes laser tracker’s measurement principle,and then integrates the domestic and foreign measurement accuracy analysis method,the angle measurement error,the distance-measuring error,incident angle error of laser,and the error introduced by environmental factors.What’s more,the coordinate error of Leica AT960 is analyzed in detail.The experimental results show that the accuracy of the laser tracker conforms to its nominal accuracy,and the measurement results possess high reliability.
