基于ALOS-2-SAR影像的建筑物检测与分析
Detection and Analysis of Building Based on ALOS-2 SAR Imagers
摘要
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 extract-ed 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 that①Cloude decomposition can analyze the features of dual-polarized SAR images,and quickly detect and identify the taller build-ings and parallel buildings.②The 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.关键词
