摘要
基于激光多边法的坐标测量系统可实现无目标点自标定,其测量精度受到自标定精度的影响。而系统的布局方式是自标定精度主要影响因素之一。通过对无目标点自标定模型误差传递规律的理论分析,对系统的布局方式进行优化,优化结果为直角三棱锥布局。仿真结果表明,直角三棱锥布局提高了自标定精度,从而保证了系统的测量精度。
Abstract
The three-dimensional (3D) coordinate measuring system based on laser multi-lateration can realize the non-target self-calibration. Its measurement accuracy is influenced by the self-calibration accuracy. However, the layout of the system is one of main impact factors on the self-calibration accuracy. By theoretical analysis of the non-target self-calibration model, the result of the system layout optimization is the tri-rectangular pyramid layout. Simulation results show that the tri-rectangular pyramid layout can improve the self-calibration accuracy, thus can ensure the system accuracy.
