Abstract : One of the most interesting tasks of scene analysis is the reconstruction problem, which is the problem of finding a three-dimensional description of a scene from two or more projections. When the scene is assumed to be composed of man-made objects bounded by quadric surfaces, the reconstruction process is simplified if the border lines in each project are given by means of straight-line segments and conic arcs. Since each projection is a digitized picture, a preprocessing stage produces a description of the boundaries in terms of point sequences. This report discusses an algorithm for converting the point sequence description to an analytic description using conic arcs and straight line segments. (Author)
