摘要: 激光跟踪测量系统具有测量精度高、实时快速、动态测量、便于移动等优点,因此,对激光跟踪仪进行现场校准和精度检测是非常有必要的.为了验证LT300激光跟踪仪的测量精度是否满足实际测量要求,用该激光跟踪仪检测固定点的测量精度和标准花岗岩三角尺的平面度.改变三角尺的测量距离和测量角度,得到测量精度与测量角度和测量距离的关系,从而得到在实际测量位置下的测量精度.Abstract: Laser tracker has the advantages of high precision, real-time, dynamic and easy to be moved etc. The site calibration and accuracy testing of the laser tracker are very necessary in actual measurement. The error of fixed points and the plane error of standard granite set square was measured by the LT300 laser tracker in order to verify the precision of the laser tracker. The relationship between measuring accuracy and distance can be found by changing the angle and distance between set square and the laser tracker. So the measuring accuracy of the LT300 laser tracker was obtained on the actual location.
