| 摘 要： | 针对当前DInSAR地表形变区检测依赖于人工的现状,提出基于Hough变换的环状地表形变区自动提取方法。该方法在外部DEM的辅助下,由干涉数据获取去地形效应的差分干涉图,在对差分干涉图进行边缘提取的基础上,利用Hough变换实现环状地表形变区的自动提取。采用青海门源震区Sentinel-1A数据和山东济宁矿区ALOS PALSAR数据分别进行环状地表形变区自动提取实验,验证了本文方法的有效性。

| Abstract: | To get rid of the dependence of DInSAR surface deformation zone detection on manpower,an automatic extraction method of DInSAR annular surface deformation region based on Hough transform is presented.It aims at processing interference data to get the differential interferogram with topographic effect removed using external DEM.Based on the edge extraction of the differential interferogram,Hough transform is used to extract the annular surface deformation region automatically.Experiments are carried out with Sentinel-1A data of Qinghai Menyuan area and ALOS PALSAR data of Jining mining area which validates the proposed method. |
