Paper Abstract

In this paper, a automatic approach of geometry precision checking for digital ortho-image (DOM), especially for a batch of DOM, is proposed. Automatic image matching between DOM with various resolution was performed in the DOM checking based on reference DOM with higher resolution. Automatic extraction of linear feature was used in the DOM checking based on reference vector map with higher precision. A lot of experiments testify that the method of this paper can improve the efficency and reliability of checking method of DOM image for geometry precision.
