固定视场光电经纬仪标校方法初探

采用固定视场和固定指向工作方式的光电经纬仪,其视场覆盖范围小,且无法进行倒镜和方位等间隔拍摄,因而不能采用具有动目标跟踪能力的普通光电经纬仪的标校方式进行标校。针对这一难题,从标校塔设计、真值测量和数据处理三个方面进行分析,提出配置多个点目标和线目标的标校塔设计思路,指出获取点目标位置真值和线目标姿态真值测量的可行途径,从试验设计、抗差估计、迭代计算等方面讨论角度测元误差模型参数的算法设计思路,给出姿态测元的计算方法和角度测元与姿态测元精度统计方法。

Discussions on Calibration of Photoelectric Theodolite with Put View

Nowadays a special kind of photoelectric theodolite appears,which works with the put view and points to a fixed point.Since its view scope is narrow and it can't work with the converse lens or with the azimuth angle changed by every small and identical step,its calibration can't be carried out like the common photoelectric theodolite,which is capable of tracking a moving target.This paper discusses the above problem in designing calibration tower,acquiring true values of position of point target and attitud...
