建筑物的提取和检测涉及诸多社会领域和经济效应。为了实现对建筑物信息的快速提取与分析,利用双极化SAR影像数据对所选研究区建筑物进行研究分析。通过Cloude分解对双极化SAR影像进行极化散射特征提取,并结合灰度共生矩阵提取的纹理特征,实现对城市建筑物信息的高精度、高效率的提取与分析。结果表明:(1)通过Cloude分解能够较好地对双极化SAR影像特征进行分析,快速实现对较高建筑物和平行建筑物的检测与识别。(2)利用灰度共生矩阵能有效地提取SAR影像的相关统计量的纹理特征并对其进行融合,实现对建筑物的高效率、高精度、全类型的识别检测。
Abstract:The extraction and detection of buildings involve many social fields and economic effects. In order to achieve rapid extraction and analysis of building information, we used dual-polarisation SAR image data to study and analyze buildings in the selected study area. We extracted the polarised scattering features from dual-polarised SAR images by Cloude decomposition. Combined with the extracted texture features by grey scale covariance matrix, we realized the high-precision and high-efficiency extraction and analysis of urban building information. The results show that(1)Cloude decomposition can analyze the features of dual-polarized SAR images, and quickly detect and identify the taller buildings and parallel buildings.(2)The texture features of SAR images can be extracted and fused with the grey scale covariance matrix to realize the high-efficiency, high-precision and all-type recognition and detection of buildings.
