Abstract

A method for the automatic registration of imagery and maps is presented, using a combination of photogram-metric and active contour model techniques. Roads appearing on the map and in the imagery are modeled as active contours, and their positions in the image determined by energy minimization on an energy surface calcu-lated as a function of edge strength. The rest positions of the contour models in the image are required to be projections of their map positions, thus maintaining the known shape of the roads. The image orientation parameters are refined as part of the road location process, yielding a simultaneous, consistent determination of the road locations and the imaging parameters and allowing well-determined features to assist the location of weaker ones.
