| Abstract: | This paper presents a method of construction matrix for projectivetransformation which includes parallel trans formation and centre (perspe-ctive) transformation. Construction of matrix with this method is onlyto require of a transformation system was given out. And it is based onthe principle of geometry. Application proves out that the method has theadvantages of the object, the brief, satisfing the need of every projectivetransformation. |
