摘要:

简要介绍了一种多方位城区高分辨率SAR图像的信息获取和地物重建方法。该方法的整个流程包括用恒虚警率(CFAR)检测器检测边缘,用平行线Hough变换从边缘提取建筑物的像,根据提取的建筑物像的统计特性,给出有各方位的像估计建筑物参数的方法。用该方法对四方位PiSAR图像做试验,得到了较好的结果。最后给出了该方法的实际应用建议。

关键词: 高分辨率SAR城区遥感    
Abstract:

A novel approach for information retrieval and 3D-object reconstruction using multi-aspect high-resolution SAR imagery of urban area is briefly introduced. It includes CFAR edge detection of SAR images, automatic extraction of building images and Maximum-likelihood estimation of building
parameters. The fidelity of this approach is demonstrated by a building reconstruction experiment on a set of square-path Pi-SAR images.

Key words: High-resolution SAR    Urban Remote sensing
