Abstract

In this article, we present a strategy to report in an automatic way significant changes on a map by fusion of recent images in various spectral bands. We focus on industrial scenes where changes concern objects like man-made structures and water areas. The approach is a two-stage processing. The first one concerns the detection of cartographic objects that do not exist anymore. The second one concerns the detection of new objects by a multispectral classification of the images. For configurations of partial overlapping between map and images, it is difficult or even impossible to formalize the approach suggested within a probabilistic framework. Thus, the Dempster-Shafer theory is shown as a more suitable formalism in view of the available information, and we present several solutions. Experimental results are presented.
