Abstract

In order to solve the problem of complex target extraction from SAR image, a fast and efficient algorithm of automatic extraction under the guide of GIS is described here. Firstly, since GIS data and SAR image are heterologous data, it is very necessary to convert vector data to image file. Secondly, select a basic target which is easy to extract in SAR image and get the feature points, so that GIS data and SAR image can be registered by modified SURF. Thirdly, nested layer of interest target on SAR image and marking suspicious areas. Take the road extraction for example, two experiments are carried out: road extraction without GIS; road extraction with GIS data. By narrowing the extract region, speed and accuracy of extraction are improved.
