Paper Abstract

A new projecting pattern is designed based on the principle of Pseudo-Random coding in this paper, and its decoding method is also studied according to Mathematical Morphology. Here, we initiate a new way which makes the feature points of two adjacent windows to validate with each other. By this way, we not only assure the validity of the matching result, but also resolve the problems of shadowing when the coded structured light is projected into the surface of the complex 3D scene, and overlapping of some parts of coding picture because of the different shooting angles of the camera, which results in the matching error of the feature points. The results of the experiments prove that the method has the advantages of simplicity and high speed. Through this approach, we can realize the automatic extracting and matching of the feature points with high accuracy.
