Reconstructing 3D Face from Multiple Uncalibrated Images

In order to reconstruct realistic 3D face model in facial animation,this paper presents a method to reconstruct 3D face model from multiple uncalibrated images.First,we build morphable models through a model normalization method based on regular grid deformation.Second,we label no more than 14 key points manually on each image,and reconstruct individual face geometry by fitting the key points on the face images.Finally,we render the face model into shape-free texture on each view,and fuse the five shape-free textures into one smooth texture image.The reconstruction results show that our method can generate realistic individual face model in the case of less manual interaction.
