D point cloud grid
4.0
Application background 3D point cloud mesh, applied to 3D reconstruction, by structured light scanning to obtain the 3D point cloud data, the point cloud data reconstruction and generate triangles. Key Technology Using the edge extension to construct the triangulation algorithm is:1 select two data points, connected as the initial baselineThird search 2 points along the fixed side of the baseline, generate the first Delauney triangle3 new baseline with two new edges of a triangle4 repeat the 2,3 until all the baseline is processed.So in the algorithm, respectively, a number of functions are used to obtain third points, according to the cosine value to determine the triangle, build a triangular network. Are based on the idea of the algorithm
