We present a low cost, hybrid active/passive 3D scanning system based on an off-the-shelf camera, a laser stripe illuminator and a turntable. The system combines the good accuracy ...

Abstract We present an effective framework for segmenting 3D shapes into meaningful components using the curve skeleton. Our algorithm identifies a number of critical points on the...
