Abstract

We propose in this paper a method to reconstruct geometrical primitives of a scene in the context of an interactive modelling system. For this type of reconstruction we use various pieces of information given by the operator: the name of the primitive and its contours in the first image. We exploit these pieces of information to extract contours of the object in a sequence of image and generate a criterion. The minimization of the criterion leads to determine location and size of the primitive which can be a cylinder, polyhedron, circle... We even propose to improve the quality of the reconstruction of primitives reconstructed separately by adding pieces of information about the whole scene. We generate a global criterion whose minimization leads to better reconstructions of the primitives. We obtain good results on real images.
