提出一种基于法向距离的法矢方向调整算法,主要思想是根据法向距离阈值,把散乱点划分为平坦点和非平坦点两种类型-We divide the scattered points into p lanar points and non 2p lanar pints according to the threshold value of a given norm al distance.

基于l1,l2 NORM 的最小二乘法，岭回归等算法，懂的人一看就知道好用，利用SVD进行计算的-Based on L2, NORM L1 least square method, ridge regression and other algorithms, the people who understand the good use, the use of SVD for calculation
