Smooth surface reconstruction from image sequences

This paper addresses the problem of 3D surface reconstruction using image sequences. It has been shown that shape recovery from three or more occluding contours of the surface is possible given a known camera motion. Recent algorithms allow the estimation of a 3D depth map of points on extremal contours. We present our approach which is based on local approximations up to order two of the surface. Such reconstruction must then be followed by a global surface description stage. This is done by constructing a triangulation of the reconstructed points and by performing a regularisation step in order to correct perturbations which affect the reconstruction. Experiments on real data were conducted which have proved the reliability of the method.
