Abstract

Aiming to solve the problem of abnormal missing holes occurred in 3D reconstruction mesh models frequently, this paper proposed a novel method that hole-defect identification automatically and detail-preserving surface repair around the hole. Firstly, in order to determine whether the hole was a real defective hole, it detected the context irregularity and contour irregularity of the missing region. After that, it detected and matched the feature lines around the hole, which were to form the fundamental surface of the hole area, and then it introduced unconstrained triangulation for basal surface. Finally, it made use of the anisotropy of mesh to refine and adjust morphologically to improve the topological and geometric properties of the mesh. The experimental results show that the proposed method can identify the defective hole and restore the hole area's detail features of triangular mesh models effectively.
