二维射影对应与透视对应的关系

The relations plane projective correspondence and perspective correspondence

研究二维射影对应与透视对应的关系,给出二维射影对应是透视对应的充要条件,得到二维射影对应可分解若干次透视对应,进而给出二维射影对应的几何意义。

This paper studies the relations between plane projective correspondence and perspective correspondence and present a necessary and sufficient condition that plane projective correspondence become perspective correspondence. Furthermore, in this paper, we have decomposing plane projective correspondence into perspective correspondences. We can give geometry meaning of plane projective correspondence.
