| 摘 要： | 针对传统方法及机器学习方法对大量三维人脸数据、训练样本数量与质量依赖性大的问题，采用基于光照立体的方法，利用人脸图像重建三维人脸。综合利用基于法线的模型变形法和非刚性变形法，提出一种基于法线的非刚性变形算法。利用SFS算法计算顶点法线，然后使用法线和局部刚性约束使参考模型变形，进而得到与参考模型具有一致网络结构的三维人脸模型，从而得到三维人脸图像。该方法与传统方法相比，节省了大量样本要求，并且立体效果更好。

| Abstract: | Aiming at the problem that traditional methods and machine learning methods depend on a large number of 3D face data， the number and quality of training samples， this paper uses the method based on lighting stereo to realize the reconstruction of a three-dimensional face from a face image. A non-rigid model deformation algorithm based on normal is proposed， which combines a normal based deformation algorithm and a non-rigid model deformation algorithm. The SFS is used to estimate the normal of the vertices， then updated normal are used to deform the reference face model with local rigid constrain， finally a deformed 3D face model is obtained， which has the same mesh structure with the reference model， thereby obtaining a 3D face image. Compared with the traditional method， the proposed method can save a lot of sample requirementsand the stereo effect is better. |
