摘要
在基于多边法的四路激光跟踪三维坐标测量系统中,猫眼逆反射器的光学误差是影响系统自标定和坐标测量精度的重要因素。对猫眼逆反射器的光学误差进行了分析和测量,介绍了测量原理、测量装置及相应的数据处理方法。实验结果表明,被测猫眼的最大光学误差约为4μm。
In the four-beam laser tracking 3D coordinates measuring system which is based on multilateration principle, the optical error of the cat＇s eye retro-reflector is an important factor which has a significant influence on system self-calibration and coordinates measuring accuracy. The optical errors of cat＇s eye retro-reflector are analyzed and measured, and measuring principal, sets and corresponding data processing method are introduced. Experiment result shows that the maximum optical error of the measured cat＇s eye retro-reflector is approximately 4 μm.
