| 摘 要： | 提出一种利用2张正交照片和细分曲面进行真实感三维人脸建模的方法,并实现了不同模型间的三维变形.为了构造个性化的人脸几何模型,将网格简化、自由曲面变形和细分结合起来,得到多个层次细节下的人脸模型;再经过纹理融合和映射,完成个性化的真实感三维人脸建模;同时利用线性插值实现了同拓扑真实感模型间的光滑变形.实验结果表明：该方法不仅可以进行有效的真实感三维人脸建模,而且变形简单流畅,具有广阔的应用前景.

| Abstract: | A new approach is proposed for modeling individualized and photo-realistic 3D human face and morphing between two heads. The approach is based on subdivision surface and two orthogonal photographs. To construct individualized geometric model, mesh optimization and free-form deformation are combined with subdivision to obtain the fine details of individualized models at different resolution levels. Then texture merging and mapping are applied to geometric model to achieve a photo-realistic representation of individualized 3D model of human face. Finally, 3D morphing between two models with the same topology is realized by simple linear interpolation. Experiment results validate our approach and show that it is not only effective in realistic facial modeling but also easy and fast in 3D morphing and therefore has a wide range of downstream applications. |
