Feature-preserving and adaptive regularizing algorithm for triangular meshes

In order to improve the triangular mesh quality of the mesh models reconstructed by industrial CT slice images, the mesh regularization algorithm combining the vertex adjustment and feature factors was presented. Introducing the improvement degree of the local mesh quality and the model feature factors as the control condition of the mesh adjustment, the local detail features of the original model were retained. The way of self-adaptive control mesh adjustment was adopted according to the normal vector threshold increasing regularity, different curvature features were identified automatically. Compared with the existing methods, experimental results show that the presented method can better regulate the triangular mesh while preserving the details features of the original model.
