Based on a two-view vision system technique and basic geometrical principles, a new algorithm for 3D texture recovery is proposed in this paper. The basic principle is to acquire two projected images from a surface and derive the characteristic line vector from each projection followed by the estimation of the normal vector of the surface. Also a new method for the estimation of the characteristic line vector is presented, called the fanshape pyramid structure algorithm. The algorithm has proved to superior to the traditional spectrum method. It can easily be extended to the multiview case or to the processing of image sequences in order to yield an improved estimation. In addition, the algorithm offers reduced computation and a simple structure for parallel implementation.
