This paper describes a new approach to recover Circular Generalized Cylinders (CGC) using deformable models . This class includes many objects present on industrial site (pipes) or on the natural environment (human leg, tree trunk) . First, we propose a modeling algorithm of objects with constant cross-section radius, called Uniform Circular Generalized Cylinder s (UCGC). With this assumption, reconstruction is possible from a single view of the object. In the case of a single image, the cross - section radius cannot be estimated . If this radius is unknown, reconstruction is achieved up to a scale factor. The model 3D axis i s parametrized by a B-spline curve . After a coarse initialization, the model changes shape to fit the object c...
