摘要
研究了基于多边法的三维坐标测量系统的自标定问题 ,并首次给出了四路激光跟踪干涉仪和测量点布局的一些指导性原则。首先从系统自标定的数学模型入手 ,指出影响系统自标定的各个因素。通过大量的计算机仿真 ,研究各个因素对系统自标定的影响规律。最后综合得到了系统自标定应遵循的一些指导性原则 ,这些原则对于实际操作时进行合理的系统自标定。
Self calibration of 3D coordinate measuring system based on multi lateration principle is discussed, the optimal method about the arrangement of the four laser tracking interferometers and the measuring points is proposed. The mathematical model of self calibration is presented at first, the factors related to the precision of self calibration are discussed through a large number of computer simulations. Finally the directive principle for proper self calibration is given, which is significant for self calibration with high precision and even improving measuring precision of the whole system.
