三维人脸恢复是视觉交互的一个难点问题,提出了一种从视频中实时恢复三维人脸的新方法.该方法利用主动形状模型进行人脸特征点提取和跟踪,确保了三维形状恢复和特征跟踪的有效性和一致性;采用非刚体形状和运动估计方法构建三维形变基,有效地适应人脸形状变化的多样性;采用非线性优化算法估算人脸姿态和三维形变基参数,实现了三维人脸形状和姿态的实时恢复.实验结果表明,该方法不仅能从视频中实时恢复三维人脸模型,而且可有效跟踪人脸各种姿态的变化.

A major challenge for vision-based user interfaces has been the construction of 3D face models in real-time. This paper proposes a novel method for recovering 3D faces from monocular videos. First, active shape model (ASM) was used to extract and trace face features in videos, guaranteeing the validity and consistency of model recovery and feature tracking. Next, a motion algorithm based on non-rigid structures was adapted to create 3D deformable shape bases as sources for a variety of face shapes. Finally, a nonlinear optimization algorithm was introduced to estimate the parameters of the face pose to be applied to the deformable model so as to rapidly reconstruct a 3D image. Experimental results proved the effectiveness of the proposed method; it robustly recovers 3D shapes and poses from videos in real-time.
