| 摘 要： | 在真实感的人脸动画系统中,纹理贴图技术是其中一个很重要的环节,它直接关系到系统的逼真度和动画的效果。提出特定人脸模型的纹理映射的技术,用圆柱投影把人脸单独3幅渲染图展开成3幅新的视图,再用多分辨率技术把这3幅新的贴图进行无缝拼接,以得到全视角无缝贴图,最后用该无缝贴图对特定人脸模型进行渲染。实验表明,该方法所得到的人脸纹理贴图非常逼真。

| Abstract: | In practical facial animation system,texture mapping is a key technique,which greatly determines the effects of animation.A new method is introduced,which extends three single mappings of facial texture to new ones by using cylindrical projection,then global seamless texture is realised through multi-level technique.At last,the global seamless mapping is used to map the special face model.This method can produce high quality facial texture. |
