摘要: 构造任意拓扑结构人脸网格的人脸动画定义表是基于MPEG-4的任意拓扑结构人脸动画系统的关键.通过搜索三维模型的二维纹理图像特征,提出一种自动地在任意拓扑结构三维人脸模型上定位特征点的方法.通过利用任意拓扑结构人脸模型上的三维特征点变形标准人脸模型,并根据标准人脸模型的动画定义表,实现了自动、准确地构造任意拓扑结构人脸模型动画定义表的方法.给定一个任意拓扑结构三维人脸模型,通过文中方法可以全自动地驱动所给人脸模型做动画.Abstract: The key point in a MPEG-4 based facial animation system is the construction of the FaceDefTables. We proposed an automatic method to locate feature points on 3D facial models and then construct FaceDefTables for arbitrary facial models based on the FaceDefTables for the standard facial model. At last, we implemented the facial animation system that can animate arbitrary facial model based on the FAPs realistically.
