针对靶场光电经纬仪多传感器不平行度误差传统修正方法参数测量困难、局限性大、修正效果差等问题,利用脱靶量角度合成原理,提出了一种基于坐标变换的不平行度误差修正方法。经实验证明:该修正方法可将经纬仪非主测量系统的测角精度提高到5″以内,且算法简单、通用性强,满足靶场多传感器装备高精度测量和数据处理的要求,推广应用价值大。

A Non-parallelism Errors Correction Method for Photoelectric Theodolite With Multi-Sensors

In order to solve the problems such as measurement difficulty,limitation and poor correction effect of the traditional correction method for the multi-sensor non-parallelism error of the photoelectric theodolite in the shooting range,an error correction method of non-parallelism based on coordinate transformation is proposed by using the angle synthesis principle of miss distance.The experimental results show that the correction method can improve the angle measurement accuracy of the theodolite non-main measuring system to within 5″,and the algorithm is simple and versatile,which meets the requirements of high-precision measurement and data processing of multi-sensor equipments in the shooting range,and has great application value.
