Paper Abstract

In this paper, we present a matching method for DSM generation from multiple images based on feature points, which introduce the coarse-to-fine strategy, geometrically constrained matching and relaxation technology, the matching is guided by the information in the object and make full use of the information in both image and object space. A match appearing in any pair has the chance to survive, and very dense disparity maps are obtained. Experiments have been performed and the height accuracy of the derived DSM is about 3 pixels.
