随着SAR分辨率的不断提高,建筑物在SAR图像上表现出越来越明显的几何结构特征,这些特征为重建建筑物三维模型提供了重要的信息。主要论述了建筑物在SAR图像上的成像几何结构,并给出了利用SAR图像上建筑物L型的叠掩结构反演建筑物三维结构的理论基础和方法,最后通过实验证明了该方法的可行性。 With the continuous improvement of SAR resolution, buildings show more and more obvious geometric structural features in SAR images. These features provide important information for reconstructing 3D models of buildings. This paper mainly discusses the imaging geometrical structure of buildings on SAR images and gives the theoretical basis and method of using inverted L-shaped superimposed structures of SAR images to invert the three-dimensional structure of buildings. Finally, feasibility.
