| Abstract: | In this paper,based on combination of HJ-1 satellite remote sensing image data contained in the multi-spectral and morphological characteristics of information,an effective extracting bridge from the HJ-1 image method has developed.The method includes the following steps：①image pre-processing;②principal component analysis;③image segmentation;④mathematical morphology.Using this satellite data,we test information extraction of the bridge.Experiments show that the method can quickly and efficiently extract the bridge information,which has a certain value in the transport industry. |
