Abstract : Recent progress in computer science makes it feasible to manipulate real object surfaces with computers. One of the resulting needs is the ability to build models o f such surfaces. In this thesis, we address the problem of the reconstruction of curved object surfaces from image sequences. Planar image contours of such objects, the occluding contours, provide rich and robust geometric information about the surface shape. In particular, local shape reconstruction can be achieved when three or more occluding contours of the surface are available. In this context, we present a global method that builds surface descriptions, from occluding contours sequences, which are based on triangular meshes. In order to improve the reconstruction procedure, different important aspects are taken into account such as the correction of noise effects and the detection of surface concavities. A number of experimentations on simulated and real data are shown throughout this document to illustrate each step of the method.
