WebDec 20, 2024 · Feature-matching using BRISK. ... FLANN is a matcher object, it will give us matches that may contain some inaccuracy, to eliminate inaccurate points we use Low’s ratio test, here I’ve made a ... 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.
