A 3D-Shape Reconstruction Method Based on Coded Structured Light and Projected Ray Intersecting Location

This paper proposes a 3D-shape reconstruction method based on coded structured light. Projecting color pseudo-random coded pattern on surface of object and using the thought of ray intersecting location, 3D shape reconstruction can be implemented by seeking the intersection point of the projection ray and the imaging ray. The former is projected ray of a feature point at projector side, and the later is image ray of the same feature point received by camera. Experimental results show that this method is effective.
