摘　　要：因特网环境下 ,与面部相关的三维造型具有广泛的应用前景 .为此 ,采用全景深度图象及其对应的全景颜色图象来描述面部三维模型 ,在此基础上 ,进行面向因特网环境的面部三维变形操作 ,并通过虚拟现实造型语言 ,在网络浏览器中 ,采用合理的折衷方法来实现 .实验结果表明 ,通过适当的自动网格划分和逼真的纹理映射等措施 ,可以在保证较好逼真度的情况下 ,使描述的数据量尽可能小 ,适合于因特网中应用 .该研究可为网上虚拟交流、网上播音、网上远程教育等提供技术支持 .应用该技术可望有效地改善因特网的人机交互界面 ,提高网络趣味性 .There is a wide foreground for 3D modeling concerned with faces under Internet environment. Panoramic range image and its corresponding panoramic color image are used to describe 3D faces in this paper. Based on it, 3D morphing of faces under the internet environment is introduced, and is attempted with reasonable tradeoff methods by using virtual reality modeling language in world wide web browser such as Microsoft internet explorer with cosmo player plug in. The results show that: with reasonable designs such as proper automatic mesh subdivision and realistic texture mapping, the describing data could be made as small as possible to fit for applications in the internet; meanwhile realistic efforts could also be guaranteed. Such a research could supply technical supports for virtual communication, virtual broadcasting and tele education in the Internet. It is expected to improve the interface and to increase the interesting of the Internet by using such a technology.
