颅面复原技术以头骨与面貌相互关系规律为科学依据,广泛应用于刑侦、考古等领域.本文综述了计算机辅助3D颅面复原技术中数据采集、颅面复原、复原后面部表情修饰等方法的进展情况.重点介绍以特征点及其软组织厚度为基础的颅面皮肤的复原技术,及曲面拟合方法的改进.最后,指出颅面复原后续工作的发展方向.

Facial reconstruction is a kind of scientific technology which is based on the rules of the relationship between skull and skin. It is widely applied in the fields such as criminalistics, archeology and so on. This paper introduces the whole process of computer aided 3D facial reconstruction, which including 3D reconstruction of a digital skull, reconstruction of skin from skull data, facial expression and animation etc. Various existing methods about the phases mentioned above are also reviewed. The focus of this paper is on reproducing three-dimensional facial skin based on a small quantity of landmarks and their corresponding tissue thickness, and improving of surface fitting. At last, the tendency of facial reconstruction is given.
