摘要
提出一种能够实现目标微小角度精密测量和空间精密角度定位的新型光电测量系统。首先建立了基于动态光学理论的光电小角度测量模型和空间基准传递模型,阐述了系统测量原理;然后基于测量模型和误差来源进行总体的方案设计,提出以降低误差为目的的系统方案设计,并且使用最小二乘法进行角度误差补偿;最后进行了系统小角度测量精度和空间定位角度精度测试。最终实验结果表明,小角度测试误差±0.6″,空间角度基准传递(横竖轴)误差≤1″,可以满足通常条件下的使用要求。
A novel electro-optical measurement system that can achieve precise micro-angle measurement and precise spatial angle positioning is proposed in this paper. Firstly, this paper establishes a photoelectric micro-angle measurement model and a spatial reference transfer model based on the dynamic optical theory, and rigorously elaborates the system measurement principle. Then, based on the measurement model and error sources, the system overall scheme design with the aim of reducing error is proposed, the overall scheme design was conducted, and the least squares method is used for angle error compensation. Finally, the tests for the system small-angle measurement accuracy and spatial angle positioning accuracy were conducted. The final experiment results show that the small-angle test accuracy reaches ±0.6″ and the spatial angle reference transfer test accuracy is 1″(2 D axes), which meets conventional usage requirements.
