基于GPS辅助空三的像控布设方案分析

Preliminary Investigation on Control Point Layout of GPS-supported Aerotriangulation

介绍了GPS辅助空三的基本原理,利用某测区的SWDC数码相机航摄资料,对GPS辅助空三加密的不同方案进行了分析,验证了《全球定位系统(GPS)辅助航空摄影技术规定(征求意见稿)》中对加密分区的划分规定及其精度,并提供了一些建议,有一定的参考价值。

This paper introduced the principle of GPS-supported aerotiangulation.Using SWDC digital photographic,we analyzed different schemes of GPS-supported aerotriangulation.It proved to be true that dividing aerotriangulation area in specifications for GPS-supported aerial photography that was reference to the similar projects.What's more,we proposed some logical suggestions which could be valuable for the surveying works.
