Abstract
Reconstruction models extracted from industrial computed tomography data may contain holes. A novel smooth hole-filling method is proposed. Firstly, we fill the holes by the minimum area triangulation, and then use refinement and edge swap principle to refine the obtained patch meshes. Finally, we compute vertex normal vector based on a mean filtering for weighted averaging face normals, the vertex is regulated in the new vertex direction by the mean curvature method. The experimental results show that the proposed approach can approximate the original missing meshes and smooth transition with the surrounding meshes.
