高分辨率影像基于影像对象的受损道路提取

摘要

基于影像对象对高分辨率影像中的受损道路进行提取，并重点介绍了易康软件中的影像分割，形成影像对象，建立道路规则库，进而提取出道路信息，并判断受损道路信息。以龙门乡受灾区为例进行试验，利用易康软件对影像进行分割并提取受损道路信息，表明基于影像对象的思想在易康对受损道路进行提取是可行的。%In this paper , it extracts high resolution images of the damaged road based on the image object , and introduces ecognition ’ s image segmentation , forming image objects , building the rules of the road base in order to extract the information of road and getting the damaged road information .Taking Longmen township disaster area as an example , it used ecogniton software to segment the image and get the information of the damaged road , which is demonstrated that the idea of image object is useful in extracting damaged road.
