Algorithms of curvature estimation and data simplification of scattered point cloud data are studied . local surface curvature properties on scattered - point data are estimated using a parametric quadric surface approximation , and the key step is local base surface parameteration method which resolves parameteration of scattered - point data . an algorithm is presented for simplifying the scattered point cloud data based on curvature restriction
实例表明,本文算法的简化结果既较好地保留了形状特征,同时使点的分布以点云密集的强制保留区为中心,在向附近扩散的过程中逐渐变稀,避免简化后点云的局部过密或局部过稀的情况。
