摘　　要：用计算机模拟人体由于其广泛的应用正在得到越来越多的重视,而作为人的最主要特征的人脸的研究也成为了计算机图形领域最具挑战性的课题之一。此论文介绍了散乱数据插值和DFFD变形方法相结合的一般人头模板修改方法。作者利用该方法从两张互相垂直的照片重建出了特定人脸的几何结构。该方法增强了DFFD变形方法对轮廓形状的控制能力,同时保持了DFFD方法的细节调整能力,最后此论文对模型采用了多方向纹理映射技术重建出了真实感人脸模型。Because of its wide application, computer human simulation is becoming more and more important. Head as the most important character of human has become the most challenging subject of computer graphics. A generic head modification method is introduced in this article, and this method is a combination of scatter interpolation method and DFFD deformation method. By this method the author reconstructs geometry structure of a special human face from two orthogonal pictures. This method has improved outline shape control ability of DFFD method, and at the same time, it can maintain detail adjust ability of DFFD method. Finally this article presents multi-direction texture mapping technique to reconstruct real human face.
