The core step of building three-dimensional face statistical model is to establish a point-to-point correspondence among 3D faces in database.
三维人脸统计模型的建立的核心步骤是确立三维人脸数据库中点对点的对应关系。
As the data points of 3d faces are huge in size and face has a complex physiological structure, thus establishing point-to-point correspondence is a very difficult problem.
由于三维人脸数据点多，人脸生理结构复杂，因而确立点对点的对应关系是非常棘手的问题。
A one-to-one correspondence between the points on two lines determined by a given point, not on either line, called the center of perspectivity or point of perspectivity.
由一给定点确定的、两条直线上的点之间的一一对应，该给定点不在这两条直线上，称为透视中心或透视点。
