摘要: 结合SAR(合成孔径雷达)图像的特性,提出一种基于融合的SAR图像中机场跑道边缘提取新方法。该方法同时采用串行融合与并行融合两种方式,对同一地区机场的2幅不同SAR图像进行处理。提出了融合MRoA算子与MSP-RoA算子和形态学开、闭运算以及融合多幅结果图的思想,通过真实SAR图像实验,证实了该算法能够较准确和全面地提取出机场跑道边缘。

Abstract: A new method for the extraction of airport runways based on fusion in SAR images whose characteristic property is taken into account is proposed.Serial fusion and parallel fusion are adopted simultaneously and 2 SAR images of the same area taken with different sensors are used for image processing.The fusion of MRoA algorithm,MSP-RoA algorithm and opening operator,closing operator in mathematical morphology together with the fusion of several result images are proposed.Compared with other methods,the experimental results of the proposed method based on image fusion using real SAR images are much better in reservation of information and boundary as well as correctness of airport runways.
