基于OpenCV环境的SIFT、SURF、ORB算法比较分析

Comparative Analysis of SIFT and SURF and ORB Algorithms Based on OpenC V Environment

介绍SIFT算法、SURF算法和ORB算法原理,分析3种算法在特征点的提取帧率与匹配数目上的差别。实验结果表明:ORB算法在特征点的提取帧率最高,SURF算法次之,SIFT算法最低;SIFT算法的匹配数目最高,SURF算法次之,ORB算法最低。

The SIFT algorithm,SURF algorithm and ORB algorithm principles were introduced and their differences in extraction frame rate and matching number of feature points were analyzed to show that,the ORB algorithm has the highest extraction frame rate and then comes the SURF algorithm and the SIFT algorithm in turn; as for the matching number of feature points,the SIFT algorithm has the highest matching number and then comes the SURF algorithm and the ORB algorithm in turn.
