旧空三成果在新航摄资料中的应用研究

Research on the Application of Old Aerial Triangulation Product in New Aerial Photography Datum

对新航摄资料进行航测成图的常规方法是重新布设外业像控,并进行空三加密。这种方法的缺点是作业时间长、投入多、未充分利用旧有资料。本文研究的内容是应用旧的空三成果和外业像控成果,对新航摄资料进行空三加密,并利用几种方法检验成果的可靠性。

The usual method for aerial photogrammetry mapping by new aerial photography datum is resetting control points and implementing aerial triangulation. The shortage of this method is that,it has long product time, high cost and hasn＇t used existing datum well. The research contents of this paper is to implement aerial triangulation by new aerial photography datum using old aerial triangulation production and control points, and to check the production reliability using several ways.
