【摘要】 描述了一种基于一维插值的人头像三维表面的重建方法。该方法从几个不同侧面的人体头部条形图获得人头像的三维条形图，经过型值点的提取，一维三次样条插值，三维重建，进而得到任意分辨率的人体头部三维曲面的数字表示及三角形、四边形网格图等表示形式。一维插值与传统的三维曲面重建的二维插值方法相比较，算法简单，三维曲面重建所需的时间也较少。该方法已在PIII 800PC机上进行了验证，获得了较好的效果。更多还原

【Abstract】 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更多还原
