一种基于联合双边滤波的网格细节过滤方法

A Mesh Detail Filtering Method Based on the Joint Bilateral Filtering

三维扫描技术被广泛应用于三维模型构造,使得三维模型拥有很多细节,但是用户在对三维模型进行模块控制时,常需要忽略掉那些细节,因此,需要对精细网格进行细节过滤。该文提出一种基于联合双边滤波的网格细节过滤方法。它使用原网格的高斯滤波结果作为后续双边滤波的法向量成分,再进行滤波,以得到最终结果。实验结果表明该方法不仅可以去除噪声,过滤细节,同时还能够保持原网格的大体信息,利于得到模型有语义的网格块。

3D scan technologies widely using in 3D modeling,make the 3D models contain many details.But when people manipu late the 3D model in blocks,these details often need be ignored.So the fine mesh need detail filtering.This paper proposes a mesh detail filtering method based on the joint bilateral filtering.It smoothes the original mesh as the normal component in the later bilat eral filtering,and then obtain the result.Experiments show that this method not only denoises,filters the detail,but also maintains the original mesh’s large scale information that is useful for obtaining model’s semantic blocks.
