| 摘 要： | 介绍空三加密更新测量实际上就是利用已成图的旧控制成果资料,在将要更新成图与新飞的航片上,利用原有的旧像控点成果再适当布测少部份新像控点,通过现有的自动空三选点量测AAT3.4及光束法区域网平差PATB-NT软件系统进行空三加密更新量测、平差、解算作业的过程。本方案在是否能达到航测大比例尺1∶1000的数字化成图的精度要求上进行了实际探讨与论述。

| Abstract: | In fact,aerial triangulation revision measurement will layout few control points of the photograph on new aerial photo in updating map area using control result of old maps.Though the use of automatic aerial triangulation point selection software AAT3.4 and bundle block adjustment software PATB-NT finish the aerial triangulation revision measurement,adjustment and solution.This paper discussed whether we can achieve the accuracy of digital mapping of 1： 1000 maps. |
