Based on traditional image stitching technique, improved RANSAC and NISwGSP algorithms are proposed, which both boosted the number of matched points and significantly improved the algorithm efficiency. The operations include using secondary matching based on grid partitioning for feature points, optimizing the algorithm through multi-threaded concurrency and optimizing parameters to reduce computational complexity. Finally after incorporating the seam estimation strategy, the ghosting phenomenon in large-disparity image stitching has been alleviated.
