GPS技术在空中三角测量中的应用

Application of GPS for Aerial Photogrammetry

介绍了GPS在空中三角测量的应用情况,以南宁市某县的一个测区数据为例,通过设计几种不同的试验方案,并用VirtuoZo软件分别进行处理,同时把结果与常规空三测量的试验数据精度进行对比,证明了GPS辅助空中三角测量的优越性。

The paper introduces the application of GPS for the aerial photogrammetry,Whose dates were from one test area of a country in Nanning.We design different measures for the test.Then by using VirtuoZo-AAT software,we can get the final consequence.This paper is focused on,through the test data accuracy analysis of the GPS-supported aerial triangulation compared with the traditional aerial triangulation.It is to prove the superiority of GPS-supported aerial-triangulation.
