摘要：Our work addresses the correction and update of road map data from georeferenced aerial images. To positionally correct the existing road network location from the imagery, we use an active contour ("snakes") optimization approach, with a line enhancement function. The initialization of the snakes is based on the existing vector road data coming from the National Topographic Database of Geomatics Canada, and from line junctions computed from the image by a new detector developed for this application. To generate hypothesis for new roads, a road following algorithm is applied, starting from the line intersections, which are already in the existing road network. Experimental results are presented to validate the approach and to demonstrate the interest of using line junctions in this kind of applications
