摘要
基于平面射影几何中二维射影变换不变元素的存在性及其求法,讨论了二维射影变换不变点与不变直线结合关系的分布特征,从理论上分析了二维射影变换不变元素的结构,并给出了不变元素的分布对射影变换的影响.
This article mainly discussed the distributed characteristics of the associative relation between the invariant point and the invariant straight line in terms of the existence of invariant elements and its solution for two - dimensional projective transformation. The structure of the invariant elements of two - dimensional pro- jective transformation is analyzed theoretically, on which the influence of the invariant elements distribution is proposed furthermore.
