Abstract
In the practical application of infrared image mosaic technology, in addition to the requirement of high stitching precision, the stitching speed should be increased as much as possible. In this paper, an improved SURF method, in which the BRISK descriptor and the Canny edge detection are applied to SURF feature extraction, is proposed based on the practical application requirements of infrared image mosaic technology. In the phase of feature extraction, SURF feature point detection is combined with Canny edge detection and the BRISK descriptor effectively to create the Edge SURF-BRISK feature. In the phase of feature matching, the threshold-adaptive hierarchical clustering method is adopted as the search strategy, and the RANSAC algorithm is used to eliminate the feature points of mismatching. In the phase of image fusion, the image gap is eliminated by a weighted fusion method. Experiments show that the infrared image mosaic method in this study can effectively improve the matching accuracy and stitching speed when stitching infrared images in complex scenes.关键词
