激光跟踪坐标测量系统的双线法基点自标定

激光跟踪三维坐标测量是一种新型的大范围坐标测量方法.在实际测量中,系统首先要经过标定,确定系统参数,然后才可以进行测量.因此,系统参数自标定的精度直接影响测量的精度.为了分析误差起因,提高标定精度.提出了一种新型的标定方法,用激光干涉仪双直线法来标定测量系统的基点坐标,通过仿真和实验,证明该标定方法可提高激光跟踪系统基点坐标的标定精度.

Double Line Method of Base Point Self Calibration in Laser Tracking Coordinate Measuring System

Laser tracking 3D coordinates measurement is a new kind of wide range coordinates measuring method.In actual measuring,the system must be calibrated and definite which parameters firstly.After that it just can be used to measure.Therefore,precision of measuring can be affected directly by precision of the base point self calibration.In order to analyse the cause of error and advance calibrating precision.A new kind of calibrating method is proposed.That is laser interferometer double line method,which is us...
