网络数据拉氏滤波的主要影响因素及其改进

The Main Factors and Improved Methods of Laplacian Filter for Triangular Meshes

对测量网络数据用正交试验法确定了影响Laplacian滤波的主要影响因素,针对Laplacian方法容易丢失特征和体积收缩大的缺点,提出了Laplacian方法的一种改进算法,改进后的算法在滤波除噪的同时,较好地保持了模型特征,减少了体积收缩。

This paper analyses the main factors which ＇affect the Laplacian filter with the help of orthogonal experiment approach on data of measuring triangular meshes. According to the false of Laplacian that makes model lose feature and shrink volume easily, improved algorithm is given out. The improved methods keep shape or feature, and reduce the shrinking of volume while smoothing the meshes.
