Matching with FLANN. … WebFLANN algorithm was used to pre-match feature points, and RANSAC algorithm was used to optimize the matching results, so as to realize real-time image matching and recognition. Experimental results show that the proposed algorithm has better accuracy and better matching effect than traditional image matching methods.
