Paper Abstract

A new ortho updating method by means of the aerial triangulation which Ground Control Points (GCPs) are auto matched from the existing ortho photos and DEM has been introduced in the paper. In this new method, a two steps automatching arithmetic have been used: the one is used in auto matching between the adjacent aerial photos in order to auto transferring tie points of the block; the other is used to matching the tie points with the existing ortho photos by the aid of DEM, if the matching succeed, the ground coordinates of the tie points could be obtained and then it could be used as a GCP in the aerial triangulation. Therefore, the ortho updating method presented in the paper could not only extract tie points, but also could extract enormous GCPs to calculate the Exterior Orientation parameters (EOP) of the aerial images with high accuracy and high reliability.
