摘    要:分析了用于建筑物测量的高分辨率SAR叠掩及角反射器效应等成像要素,并将其与高分辨率快鸟卫星图像融合,实现了建筑物屋顶信息的提取。进一步利用SAR叠掩得到的建筑物高度信息和快鸟图像得到的建筑物屋顶信息实现了建筑物的三维重建。与实地测量数据相比较,计算结果精度较高,从而验证了这种三维重建方法的可行性。

关 键 词:高分辨率  SAR  叠掩  融合  三维重建

Abstract:This paper analyzed the layerover and corner reflection of building in high-resolution SAR image,and the roof information of building in Quickbird optical image.The information of building's height,width and location was extracted from SAR image,and the information of building's roof was extracted by fusing the SAR image with optical image.The 3D reconstruction of buildings was finished with the height computed from SAR image and the housetop outline obtained from Quickbird image.Compared with the real information about some buildings,the information obtained from test images is accurate and the method of 3D reconstruction is a good ideal.
Keywords:high-resolution   SAR   layerover   fusion   3D reconstruction
