高分辨率SAR与光学影像联合调绘研究

摘要

In order to solve the problem of low efficiency of annotation in topographic map, on the basis of analyzing the characteristics of SAR and optical images, the annotation method is used to combine high resolution airborne SAR image with optical image, and the experiment of 1∶5 000 topographic map annotation has been carried on.Finally, the workload of SAR image, Google Earth image and joint annotation are used to make the contrast analysis with the method of Analytic Hierarchy Process.It turns out that the field work is reduced greatly, and the working hours is shortened by the method of joint annotation.%为解决地形图测绘中外业调绘效率低问题,在分析SAR影像与光学影像特点基础上,利用高分辨率机载SAR影像与Google Earth影像联合调绘方法,进行1∶5 000地形图调绘实验.通过层次分析法对SAR影像、Google Earth影像以及联合调绘方法的工作量进行对比分析.结果表明:联合调绘方法能大大减少外业工作量,缩短作业时间.
