As to the problem that plane ' s normal has two opposite direction , we using " direction spread " to resolve it . examination result show that adopting adjacent points " main normal direction as current point ' s normal direction can resolve that problem and provide reliable information to points " classification 对于法向量存在两个相反方向的问题，本文使用了“方向传播”的方法，由邻域中法向量的主流方向确定待求点的法向量方向，实验结果表明可以较好地解决法向量方向不统一的问题，为后续的数据点分类提供可靠依据。
