Paper Abstract

This paper describes the use of Disparity Space for automatic stereomatching, differential rectification and DEM production. Any matching technique which produces local (potentially ambiguous) matches can be incorporated within the Disparity Space system. A fast, optimal solution is obtained using Dynamic Programming. We have combined image intensity, local edge magnitude, local edge orientation and the output from a Laplacian of Gaussian to obtain very dense range maps. Experimental results with close range images are reported. The method has been implemented on a UNIX Workstation and is highly suitable for implementation with parallel processors.
