基于标准模型的三维人脸建模与控制

METHOD OF 3D FACE RECONSTRUCTION BASED ON STANDARD MODEL AND FACIAL EXPRESSION

提出了一种通过两幅正交人脸照片合成三维人脸模型的方法.该方法依据MPEG-4标准定义的特征点标记照片,将其与三维标准模型的特征点进行匹配调节,然后采用铰线形变方法对网格化正面照片进行曲面化,进而将曲面化的三维人脸与标准三维模型合成得到真实感人脸,在此基础上通过三维坐标驱动实现人脸的表情控制,最后通过实验验证了该方法的有效性.

Syntheticed 3D model of human face using two orthogonal face photos, marked the two photos according to the characteristics points based on the MPEG-4 standard. And then adjusted the standard 3D model＇s characteristic points to match the photos＇ points, deformed the front grid photos used the special bezier curve deformation method, using the result photos and the standard 3D model to synthetic realistic face. Finally realized the control of mouth-shape change based on the 3D coordinates driven.
