本文以定位器支撑的大部件调姿系统为研究对象,通过激光跟踪仪测得大部件上多个测点坐标数据。针对各点在不同坐标系下测量点值不匹配且各点精度要求有差异的问题,提出了最小二乘法评估大部件位姿的模型,并利用权值实现对多个测点数据进行误差分配优化,为大型部件的位置姿态评估计算提供一套有效的解决方案。
In this paper, the locating system of large parts supported by the locator is taken as the research object, and the coordinate data of many measuring points on the large part are measured by laser tracker. Aiming at the problem that each point does not match the point values in different coordinate systems and the precision of each point is different, a least square method is proposed to evaluate the pose of large parts. The weight distribution of multiple points Optimized to provide an effective solution for the evaluation of the position and attitude of large components.
