Overview of Image Matching Based on ORB Algorithm

ORB image matching is of great significance in the field of image processing, which is mainly used in navigation, target recognition and classification, image stitching and remote sensing registration. Based on the existing literature on ORB algorithm research, this paper first introduces the classic ORB algorithm. Then, the various improved algorithms of ORB are expounded, and the performance index of image matching algorithm based on feature points is introduced. Finally, the shortcomings of the ORB algorithm are pointed out and the development direction of the algorithm is prospected.
