解析空中三角测量的作业流程研究

Analytical Aerotriangulation-engineering Research

介绍了VirtuoZo AAT软件解析空三加密的主要流程,结合本次设计的区域进行解析中三角测量加密,总结出在作业过程中提高精度和作业效率的一些方法。解析空中三角测量的作业流程主要包括测区基本参数的设置、影像列表的建立、全自动内定向、确定航带间的相对位置、自动提取连接点、连接点的编辑和PATB平差软件的使用。论述了在使用Vir-tuoZo AAT软件进行解析空中三角测量加密的过程以及在操作中可能出现的问题,提出通过精确刺点、多次加密等方法来解决,从而使测量精度得以改善。

This paper is to study the processes of Analytical aerotriangulation. Combining the territory of designing in this paper of photogrammetry-based theory of knowledge is to the air encryption. Then it introducts the major process of the air triangulation analytical in the VirtuoZo AAT software and its principal. Meanwile it sums up some ways to improve the accuracy of actual operation and using the VirtuoZo AAT sofftware to the air encryption. Analysis of aerial triangulation processes are very important,which contains the basic parameters of the test zone settings,images of the establishment of the list,with automatic orientation,established with flights between the relative position,automatically extract connection point,the connection point of editing and the use of PATB. This article discusses the use of analytical software VirtuoZo AAT air encryption process and the possible problems,through the precise point,multiple stab encryption and other methods to solve the above question. So we put forward some useful proposals.
