Abstract:

合成孔径雷达(syntheticapertureRadar,SAR)影像的精确配准是使用SAR影像准确分析矿区变形的前提。虽然目前已有的影像配准算法很多,但是直接应用于SAR影像配准的效果还不够理想。为此,提出了一种集成互补不变特征的配准方法。该方法首先利用Canny边缘检测算法对影像进行区域分割,利用获得的分割区域进行粗匹配,然后应用改进Canny边缘特征的SIFT算法进行精匹配,最终获得精确配准的SAR影像。该方法能够降低由单纯使用SIFT特征进行匹配所产生的巨大计算量。通过实验分析可知,该方法能够准确配准矿区SAR影像,为矿区变形分析和综合治理提供高质量的影像数据。
