图结构在航空遥感图像特征点匹配中的应用
Application of graph structure in aerial image feature matching
摘要
Abstract
The aerial remote sensing image captured on the sea has the characteristics of dynamicity, monotonous and similar patterns, which may result in mismatches in feature matching. In order to remove the mismatches and improve the efficiency, a feature point matching algorithm based on graph structure is proposed. There are two stages in feature matching process, coarse matching and fine matching. In the coarse matching, Speeded Up Robust Features(SURF )is used to get an initial matching results. In the fine matching, Restricted GTM(RGTM)is proposed. Both local spatial structure and global information are considered. KNN graphs are constructed by the initial points. Then feature matching is converted to graph matching and global transformation error is used to restrict the matching convergence. The experimental results show that the proposed algorithm is more efficient and accurate than GTM.关键词
