激光雷达坐标测量系统的测角误差分析
Angle measuring error analysis of coordinate measuring system of laser radar
摘要
Abstract
In order to design coordinate measuring system of laser radar precisely, based on the measuring principle and structure of laser radar coordinate measuring system, a angel measuring error model was built with three main system errors of peipendicularity error of pitch axis and azimuth axis, tilt error of reflector and tilt error of incident laser beam. After theoretical analysis, the maximum error values of single point coordinate measurement from 10m, were 124. 1μm, 447. 9μm and 242. 4μm. The results show that, in the design of laser radar coordinate measuring system, it is necessary to strictly control system error parameters like peipendicularity error of pitch axis and azimuth axis, tilt error of reflector and tilt error of incident laser beam in order that the measuring system has high measurement accuracy when measuring in large space. Besides, parameter calibration and error compensation are required to improve the measurement accuracy.关键词
