【摘要】 针对由单幅照片进行三维人脸自动重建的问题,提出了基于一般模型变形的快速三维重建方法.先通过稀疏形变模型获取照片人脸特征点的深度信息,再将一般人脸模型变形到特定人脸,并使用基于肤色模型的插值合成皮肤纹理.实验证明,三维人脸重建方法快速简便,且只需单幅人脸照片,真实感强,并且可生成多种姿态、光照和表情的人脸图像,有较好的应用价值.更多还原

【Abstract】 According to the problem of 3D face reconstruction from one image,this paper proposed a quick face reconstruction approach based on morphing a generic model.First depth information of the given image is got by fitting sparse morphable model to 2D feature points.Then a generic model is deformed to particular face model.It also proposed a skin model based texture mapping technique to better synthesise the side face texture.The experiments show that this approach is fast and efficient and requires only one image;the result is realistic.As various poses,illuminations and expressions can be generated by the 3D model,this approach can be well applied in many fields.更多还原
