Research on Workpiece Image Registration based on SIFT Algorithm

Abstract

With the development of digital image processing and computer vision technology, image registration technology has become an extremely important technology in the field of image processing. In recent years, many scholars at home and abroad have carried out in-depth research on image registration, and proposed a variety of effective image registration methods. The most classical one is scale invariant feature transform (SIFT) proposed by Lowe. SIFT features keep good invariance under the conditions of image rotation, angle transformation, affine transformation and scale scaling. As an important part of image registration, feature matching has always been a hot topic. The main work of this paper is image registration based on SIFT algorithm, which aims to search and match feature points.
