给定栅格图象及其变形后的栅格图象，请你首先确定各栅格交叉点的位移，然后采用控制栅格的方法编写实现图象几何校正的程序。

实验图象：point.bmp, point_sp.bmp, tiger_sp.bmp



自己写的，函数分离，有注释-To set the raster image and its deformation raster image, you first determine the displacement of the crossing point of each grid and control grid method for the preparation of the image geometric correction procedures. Experimental images: point.bmp point_sp.bmp tiger_sp.bmp



written by myself, function sperated and　with comments
