In this paper, the author's demonstrate a 3D object modeling system utilizing a setup which consists of two CMOS color cameras and a projector by making use of structured light and stereo vision. The calibration of the system is carried out using a calibration pattern. Images are taken with stereo camera pair by projecting structured light onto the object and a 3D point cloud is reconstructed by using both unipolar constraint of stereo vision and gray-code constraint of structured light. Additionally, separate 3D point clouds are extracted performing ray-plan intersection between camera-projector pairs.
