垂直射影 [chuí zhí shè yǐng]
vertical projection
- 摘要针对单张人像的三维姿态计算，结合面貌测量和射影几何的理论提出了一种方法：首先在人面部的平面区域内，选取眼角点，口角点，鼻翼点建立人脸模型;然后根据人脸平面上两个相互垂直的特征线投影到照片上的灭点位置，求出人脸平面的旋转方向。
Abstract Aiming at 3D pose computation from single facial image, a method was proposed based on the theory of anthropometry in face and projective geometry: first, corners of eyes and mouth, and nosewing points were selected to establish facial model within facial plane; then, the orientation of face was determined based on the location of vanishing points in image, which were resulted from two perpendicular features lines in perspective project.
