摘要
大量的三维网格是建立在三维扫描数据的基础上,有效地去除在扫描过程中引入的噪声成为3D造型技术中的一个关键问题。双边滤波在图像平滑中具有非常优良的效果,将其运用到3D模型去噪,提出了一种各向异性的网格去噪算法,所给出的局部估计方法同时分别考虑顶点邻域三角形的空间距离和邻域三角形切平面信号的影响,使去噪的效果更加接近原始实物模型。
A mass of 3D meshes are obtained by 3D scanning, and it＇s a key problem to eliminate the noises causing by scanning process. Bilateral filtering is used very successful in image denoising, it can also be used in mesh denoising. An anisotropic bilateral filtering method is introduced in mesh denoising, local estimates in which are involved both space distances and tangent planes of adjacent triangles of the mesh.
