SAR图像建筑物成像特性及重建研究方法

Research Methods on the Reconstruction and Imaging Characteristics of Building from SAR Image

基于SAR图像中平面屋顶建筑物的成像机理,介绍SAR图像中建筑物的信息获取和重建方法,包括成像特性、建筑物平面长条屋顶的提取、建筑物高度计算。通过成像原理,利用建筑物二次散射亮线及叠掩、阴影区域定位建筑物屋顶区域,再结合叠掩、阴影区域反推出建筑物高度的计算公式,实现建筑物三维重建。

Introducing the research method of building information acquisition and reconstruction from SAR image,which based on the imaging mechanism of flat rectangular roof building in SAR,including imaging characteristics,building flat strip roof extraction,building height calculations.Through the imaging principle,using secondary scattering bright lines and layerover and shadow to locate the building roof region,combined with layerover and shadow region to calculate height,achieve three-dimensional reconstruction of the building.
