摘要
给出透视变换定义,研究了透视变换与透视对应的关系,利用直射变换可分解为透视变换,得出直射变换的充要条件,进而给出直射变换的透视定义.
The definition of perspective transformation is presented, the relation between perspective transformation and perspective correspondence is studied. A sufficient and necessary condition of collineatory transformation is derived through decomposing collineatory transformation into perspective transformation. Furthermore, we can give perspective definition of collineatory transformation.
