Abstract 

This talk presents a stereo-vision system for a complete 3D model reconstruction. A multi-view modeling technique including registration and integration of multiple range images is presented. A pose estimation and integration technique of two 3D pose-models is also presented for a complete 3D model reconstruction. In order to reconstruct a complete 3D model of an object, we record two poses of the object, register and integrate two pose-models to a complete 3D model. Coarse registration between two pose-models is facilitated by a novel pose estimation technique. The pose is estimated by matching stable tangent plane (STP) of each pose model with the base tangent plane (BTP) which is invariant for a vision system. After the pose estimation, two pose models are then integrated to a complete 3D model. A fast and accurate point-to-plane registration technique is also presented.
