This paper studies an automatic 3D shape reconstruction of objects using images taken by a camera from different views based on photometric stereo technique. The automated data acquisition system consists of a camera, lighting system that consists of 60 LED bulbs, and a turntable rotated by a computer-controlled stepping motor. We use photometric stereo techniques, which recover surface normals of an object on a per-pixel basis from a set of images captured from a fixed viewpoint under various lighting directions, and then recover the height field function from the normals. Finally we merge all the height field function to reconstruct the object. Examples are provided to demonstrate the effectiveness of the proposed method.
