Abstract:Threedimensional modeling is a basic problem in the field of computer graphics and computer vision. Face with its unique common and strong personality and other characteristics, as many advanced 3D modeling algorithm experimental platform. However, due to the diversity of face, complexity, the establishment of a strong sense of the goal of threedimensional face model has become a challenge for many researchers, computer simulation of specific threedimensional face, both in academic research and practical applications are of great significance. On the basis of combing the literature, this paper summarizes the research results of real threedimensional face modeling theory and practice, summarizes the research methods of 3D face reconstruction in recent time, and analyzes the advantages and disadvantages of various 3D face reconstruction methods, a few issues to be further studied and future trends.
Key Words:realistic 3D facial modeling; 3D data acquisition; virtual reality; computer vision
0引言
随着计算机图形学及虚拟现实等技术的发展,尤其是虚拟播音员的出现,基于虚拟人物设计的研究被广泛重视。人脸包含了大量的特征信息,是辨别人物最主要的器官,特定人脸的计算机模拟研究具有重要意义。真实感三维人脸模型在影视制作、计算机游戏、远程教育、医学美容、智能识别等应用中举足轻重。在学术研究方面,三维人脸重建与表情口型模拟、人脸识别、医学图像处理、人机交互等研究课题相辅相成,其研究成果可推动相关研究。Parke[1] 20世纪70年代建立了第一个脸部模型,其后研究不断深入。真实感三维人脸重建可分为两种途径:①采取三维扫描仪等较复杂的硬件装置,辅以一些较简单的算法来获取人脸的几何和纹理数据;……
