摘要
光电经纬仪在外场使用中,由于潮湿、冲击等多种环境因素影响及其系统同步、器件性能变差、软件等原因,造成图像与测量数据同帧合成出错,精度严重下降,数据不能使用。由于外场检测条件有限,错帧合成不易发现,外场检测方法亟待解决。文章基于经纬仪存储系统的图像与测量数据同帧合成设计策略及合成方法,分析错帧合成的表现特征,针对外场使用条件,提出采用动态测量固定目标法检测同帧合成的正确性,并进行了测试验证,该方法简便、实用。
Error in same-frame synthesis occurs when photo-electric theodolite is used in airfield, due to the influences of surroundings and equipment factors, such as humidity, impact, asynchronous, performance degradation, and so on. This will induce accuracy decline and unusable measurement data. Therefore, it is an important issue that how to find the different-frame image and data synthesis in airfield. A method was presented to determine whether the image and data were correctly synthesized in airfield, based on the strategy and method of same-frame synthesis using original image and measured data in storage systems. The dynamic measurement of the fixed target shows this method is simple and practical.
