Reconstruction of the 3D Surface of Head Based on 1D Interpolation

This paper presents a method which is based on 1D interpolation to reconstruct the 3D smooth surface of head. Based on the several part-line-head of profiles, a 3D line-head is reconstructed, and then three steps are needed, including distilling the control points, interpolating based on 1D-cubic-spline, reconstructing the 3D-surface. After these steps, the 3D digital surface of head with the arbitrary resolution is formed, and the surface can be described by triangle-grids, rectangle-grids or other forms. Compared with traditional 3D surface reconstruction methods, such as two-dimension interpolation, the algorithm has several advantages, such as simple arithmetic, and little time spending for reconstruction. The algorithm has been implemented on a PIII 800 PC coming out with good results
