An Automatic and Robust Approach to 3D Face Reconstruction
Hu Q · Microcomputer Information · 2007
3D facial model have been widely used in many fields,such as video telephone,video conference,movie making,PC game,face recognition,etc. Multiple images are usually used in 3D facial modeling and faces in images must be natural expression. This paper proposes an approach to using frontal and lateral 2D image,to reconstruct a 3D face. First of all,facial features are extracted from the face in the 2D image,which contain many useful information for 3D reconstruction. Then a generic 3D face model is adopt-ed to fit a special face in the 2D image by means of scaling,shifting and rotating. Then,facial texture is obtained from the image. After mapping the 3D face model co-ordinates into the texture space,texture co-ordinates of the 3D face model can be generated. Experimental results show that the developed method to reconstruct 3D face is effective and robust.
