The invention provides an approximate image difference detection method based on a domestic CPU, and belongs to the technical field of image contrastion.The method comprises the steps that a feature matching algorithm is used, the transformation relation of two approximate images is worked out, homography transformation is established, a detection area is determined, the determined area is divided, and difference judgment is conducted on the divided area; the method comprises the following steps of: determining whether the areas have differences or not, marking the areas with the differences, and finally clustering the detected difference points through a clustering method so as to solve the difference part of the two approximate images. The method has good applicability to image states, illumination changes, image viewing angles and the like, and the problem of difference detection of approximate images is solved. 本发明提供一种基于国产CPU的近似图像差异检测方法，属于图像对比技术领域，本发明使用特征匹配算法，求出两幅近似图像的变换关系，建立单应性变换并确定检测区域，通过对确定区域划分，对划分区域进行
