ransac是常用的稳健计算机视觉的方法，可用于两幅影像的配准。本源代码用仿摄模型模拟两影像的几何变形，用ransac算法来剔除错误匹配点，得到最终的仿摄参数。-ransac is commonly used in computer vision of a stable, two images can be used for the registration. Imitating source code model perturbation two images of the geometric deformation, ransac algorithm used to remove erroneous match point, imitation is the ultimate parameter perturbations.
