| 摘 要： | 首先对4种常见的尺度和旋转不变特征算子：SIFT,SURF,MSER,ORB进行简单的介绍。为定量比较各种特征算子在航空影像自动转点中的性能,本文提出了3种与倾斜影像相关的指标,并结合常用的4种指标组成本文的7个定量评价指标。在此基础上,采用一组倾斜影像数据进行了试验,结果表明,SURF/SIFT算子在航空倾斜影像空三转点中具有相对较好的性能,MSER次之,而ORB的效果较差。

| Abstract: | This paper briefly introduces four common scale and rotation invariant feature extraction operators： SIFT,SURF,MSER and ORB at first then three criterion related to oblique images aerial triangulation are proposed and combined with four regular used quantitative evaluation indicators to evaluate the tie point transferring processing on oblique images aerial triangulation. After that,a serial of aerial oblique images are used to perform the comparative study. The experiment result reveals that SURF and SIFT algorithm can achieve better results on oblique images aerial triangulation,followed by MSER algorithm,while ORB obtain bad results. |
