已知图象4点坐标和转换后图像相对应4点坐标， 利用openCV求出homograghy 3x3 矩阵， 然后输出变换后图像,There is an input image called "warpin". The goal is to warp this image so that the tiles are approximately square, that is the camera is rotated to look down, which produces an image call

给定两幅图像，人工指定四对点，程序会根据点对计算出两幅图像的变换对图像进行配准-warp image for registration

该程序利用MATLAb语言进行Ｈｏｍｏｇｒａｐｈｙ矩阵计算，即从３维空间到２维空间的变换-The the program utilizes MATLAb language Homography matrix calculated from the 3-dimensional space to the transformation of the two-dimensional space
