| Abstract: | According to practical applications,this paper extracted the information of the road,which were overlooked and low contrast in the high-resolution remote sensing images road characteristics analysis,by semi-automatic urban road network extraction method based on statistical information.At the same time,it returned to the middle and the bottom of the results to further verification after dealing with extraction in the high-level knowledge during the road extraction,in order to prove the method is effective. |
