【Abstract】 This paper presents an image orientation and matching algorithm, which is based on correlative matching method. This algorithm makes use of image correlation to realize image orientation and matching. And through pyramid algorithm, it also compensates the shortage of large computing caused by correlation. It has been proved in auto detect system of actual printing quality that this algorithm has the properties of high precision and speed.更多还原
