光电经纬仪CCD相机作用距离分析研究

Analysis and Research on the Working Distance of CCD Camera in Photoelectric Theodolite

光电经纬仪作用距离是衡量其测量能力的重要指标,是其作用威力的具体体现。论文通过某型光学测量装备使用环境特点和设计要求,从相机靶面尺寸、像面照度和像面与背景对比度三个方面,对光电经纬仪可见光CCD相机对海对空作用距离能力进行了理论分析,验证了在外场使用条件下可满足设计指标要求。并结合作用距离理论计算值和外场试验实际测量数据真值进行对比,分析存在不同原因,提出了装备使用建议。

The working distance of photoelectric theodolite is an important index to measure its measuring ability,and it is the concrete embodiment of its working power. In this paper,according to the use environment characteristics and design requirements of a certain type of optical measurement equipment,theoretical analysis and estimation are made on the sea-to-air action distance of visible light CCD camera of field photoelectric theodolite. Combined with the test data,it is verified that it can meet the design index requirements under the use conditions of field,and some suggestions for equipment use are put forward.
