A portable 3D scanner based on structured light and stereo camera

To reconstruct the 3D model of a large structure, multiple measurement from various angle are required. In this paper, we propose a portable 3D scanner system which combines narrow-baseline stereo camera and consumer video projector. In proposed system, we can settle camera and projector in arbitrary position and angle. The relative position of camera and projector is automatically calibrated from image sequences. The proposed system realizes high measuring flexibility, because stereo camera and projector do not need to be fixed.
