Combing structured light measurement technology with binocular stereo vision

3D measurement technology is one of the important research fields in computer vision. 3D measurement based on binocular stereo vision is a typical measurement technique. In this paper, the structured light technology is combined with binocular stereo technology. The structured light can increase the feature of object's surface, so we can reconstruct the surface of object more robustly. In this paper, we establish the 3D imaging system, obtain the point of 3D coordinates on the imaging plane, and then extract the center of the stripe image. Based on the stripe center, we propose a new method of matching. At last, we reconstruct the 3D surface of the object by calculating the interception points of two rays with analytical solutions. The experimental results show that the method is feasible and efficient.
