A New Modeling Method on Skull Defect Repair
To obtain the fairing surface model of the loss part of detective skull rapidly, a new modeling method on skull defect repair is proposed in this paper. This method is to adopt the surface reconstruction algorithm to construct the local model of defective skull based on the sub-pixel cube model. The holes feature on the surface is automatically identified by adopting the dihedral angle criteria algorithm, and two three dimensional polygons are generated by searching the boundary edge of the hole. The polygon is triangulated based on the minimum area principle, and the mesh is refined based on the shortest edge principle. The weighted umbrellaoperator is appfied to control the curvature transformation of the patching mesh for smoothing it, and the fairing surface patch is generated. Then, the prosthesis model of defective skull is generated by Boolean calculation between every two key models. The modeling efficiency and precision are too higher.
