POS辅助UCD航空摄影测量直接地理定位误差分析
Error Analysis of Direct Georeferencing in POS Associated UCD Photogrammetry
摘要
本文分析了POS辅助UCD相机航空摄影测量直接地理定位误差的来源，根据望城测区进行了实际精度分析，结果表明采用地面元分辨率为7.2厘米的UCD影像，将POS直接获取的外方位元素经偏心角改正和相机内方位元素自检校改正后，通过直接安置可以满足1：1000地形图的成图精度要求。Abstract
This paper analyzes the error origins of DG in POS associated UCD camera photogrammetry and the true precision based on WangCheng project, we can get the collusion of that using the GSD 7.2 cm image of UCD,the exterior orientation of POS that has been calibrated by boresight angles and the interior orientation by camera self-calibration, through DG can satisfy precision specification for topographic mapping at a scale of 1:1000. 关键词
