高分辨率SAR图像建筑物三维成像几何结构分析

3D Geometrical Feature Analysis of Buildings on High-resolution SAR Image

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。

As the ability of SAR to acquire high-resolution image is increasing,the geometrical features of building,which provides important clue to reconstruct 3D model of building,are becoming clearer.We discussed the imagery configuration of building on SAR image,and present how to use these geometrical features to reconstruct 3D model of building.At last,two SAR slice images which contain remarkable L-shape layover of building were experimented on to verify the feasibility of this method.
