In this paper a new vision based method for 3-D geometric model construction and pose determination of a curved object is proposed. The key concept in the proposed method is to derive the 3-D object information using some planar patch passing through the object stripe junctions or silhouette edges. This patch will be referred to as a virtual plane. We can derive the virtual plane to obtain the 3-D object stripe junctions or the 3-D silhouette edges of some specific primitive curved objects. Based on the derived 3-D object information, we propose two methods to estimate the shape parameters of primitive objects. The shape parameters completely specify the geometric model of the primitive object. The shape parameters also reflect the pose information (location and orientation) of the object. Experimental results indicate that our method for determining the 3-D surface points and shape parameters of primitive objects are accurate and fast.
