| Abstract: | Analyze SIFT algorithm for feature extraction and matching, and by using the matching strategy of improved algorithm of SIFT eigenvector match pairs＇ uniqueness constraint, propose a bidirectional matching algorithm. Based on existing matching results, the algorithm introduces matching uniqueness constraint to further reduce matching error during matching between real-time image and reference image sequences, thus to find the known landing area in real-time image and improve image matching accuracy. Experiment results show the method is effective. |
