摘　　要：创建逼真的三维人脸模型一直以来都是计算机图形学领域一个极富有挑战性的课题。利用左右斜侧面照片生成具有纹理信息的三维人脸。分别对两张左右斜侧面人脸照片通过纹理三角剖分和仿射变换映射至标准纹理模板,再利用计算机视觉和facegen生成的人脸数据库上应用中的算法生成一个三维真实几何模型,最后将纹理映射三维模型生成具有纹理信息的三维人脸。结果表明方法的合成结果与真实人脸在模型以及纹理方面具有较好的相似性。Generating realistic 3D face model is a challenging task in computer graphics and computer vision.This paper proposed a method of 3D face reconstruction method based on two half-frontal photos.Firstly,it designed a texture template.Secondly,the photos were mapped to formal texture template through triangulation and affine transformation respectively.Thirdly,computer vision techs and an algorithm based on a face database produced by facegen were used to generate a three-dimensional model of the real face.Lastly,after the texture was mapped to the three-dimensional model,the final three-dimensional face was created.The experiments show that results of the reconstruction approach is greatly similar to real face in 3D model and texture.
