Xiaohu Jiang · Computer Knowledge and Technology · 2015
Taking into account the problem of poor effect and slow matching in image mosaic caused by phenomena such as the rotation and the differences in light intensity, a steady image stitching algorithm based on SIFT and improved RANSAC is proposed, specifically including SIFT feature extraction, image registration and the weighted average image fusion. Among them, the paper focuses on the image registration at this stage, this phase includes an initial matching and accurate alignment. Experimental results show that the proposed image mosaic method can not only yield good results for images with overlap region that existence translation, rotation, image scaling, image viewing angle and illumination changes, and compared with the original RANSAC algorithm, the improved method has lower computational complexity, less stitching time, and splicing efficiency has been significantly improved.
