摘　　要：三维人脸的重建是二维半雕刻系统的核心内容,提出了一种从正、侧面图像上自动提取特征点来修正通用模型从而重建三维人脸的方法。首先使用特征点模板匹配的方法自动提取出特征点,然后以这些特征点为依据,通过整体变换和径向基插值来修正通用模型得到特定人脸。同时建立了一个人脸模型库来获得特征点模板,并且提出了一种分块存储的方法可以更精确地针对脸部不同区域进行重建。实验验证,这种方法效率高、交互操作少、取得了满意的重建效果。3D Facial Reconstruction is the central part of 2.5D Carve System. In this paper, a reconstruction approach based on a general model is proposed. The algorithm starts by computing the 3D coordinates of automatically extracted facial feature points. The coordinates of the feature points are then used to deform a generic face model to obtain a 3D face model for that person. We construct a face database and put forward a new method by which the whole face model are divided into many parts according to its structure. Preliminary experiments for lace reconstruction show encouraging results.
