Abstract
A triangulation Algorithm of Depth Images based on Self-adaptive Quadrangle mesh is proposed in this paper. Depth images will be triangulated in two steps. Firstly, self-adaptive quadrilateral mesh is generated based on depth images. Row and column pixels of quadrilateral mesh can be obtained using uniform sampling method. Quadrilateral mesh is generated by connecting adjacent row and column pixels. Secondly, each quadrangle consists of two diagonals and triangulation is generated by selecting diagonals with larger directional angle difference.
