面向应用的个性化3D人脸模型快速生成技术
|
摘要
真实感3D人脸模型生成技术是计算机图形领域研究的热点问题之一,但已有的相关方法存在真实感差、算法复杂度高、局限性多、实用性弱等问题.在分析3D人脸模型姿态矫正和模型变换方法基础上,研究基于一张人脸正面图像和普通3D人脸模型、采用关键特征点匹配和真实感纹理映射方法构建个性化3D人脸模型的方法,最后利用基于C++和OpenGL实现的原型系统进行实验分析.实验结果表明该方法计算简单、建模效率高,且适用于影视特效制作、3D网络游戏、医学美容等领域.
Realistic 3D face modeling has become the focus of researches in computer graphics,but the existing researches have not provide a convenient,efficient,realistic 3D face models generation method.Based on the analysis of pose correction and transformation of 3D face model,a method of personalized 3D face modeling by matching a few key feature points is discussed,which need only a face picture and a common 3D face model.Then,a prototype system was implemented using C++ and OpenGL,and the experimental results suggest that the proposed method is easy and efficient,and can be widely used in film and advertising,3D network games,and medical hairdressing,etc.
