Method of establishing a general mathematical model of structured light 3D vision

In this paper, the principle of structured light 3D vision is briefly introduced and the method of establishing its general mathematical model is given in detail. Applying perspective, translation and rotation transforms in homogeneous coordinate system to structured light 3D vision, the model possesses the advantages of high accuracy, great simplicity and high generality. This gives the conveniences on reconstructing the surface coordinate of an object.
