摘要: 针对影视动画领域,利用LS_5000型三维激光扫描仪,提出了一套真实感三维人脸快速建模算法。只需输入真实演员人脸的三维扫描点云和未定标的照片,以及极少的人工交互,即可生成虚拟演员真实感的三维人脸模型(包括几何模型、纹理模型和面向动画的可变模型)。实验结果表明,算法输出的模型简洁规范,可直接应用于实际的影视动画制作,提高了人脸模型建模效率。

Abstract: Using LS_5000 3D laser scanner, an efficient realistic 3D face modeling algorithm was proposed to create virtual actor for film and TV animation. Inputting the point cloud data and uncalibrated photographs of the real actors face as well as little user interaction, the algorithm can generate realistic 3D face models including geometry model, texture model and deformable model for expression animation. Experiments show that the output 3D face is ideal to be directly used for film/TV animation and can enhance the speed of facial modeling.
