融合光学信息的阵列干涉SAR三维成像
3D Imaging of Array Interferometric SAR with Integrated Optical Information
摘要
Abstract
Synthetic aperture radar(SAR)three-dimensional(3D)imaging technology provides vertical resolu-tion and effectively addresses the issue of image stacking in SAR imaging.However,existing technologies face challeng-es,including long data acquisition periods and high costs,and the reconstruction results are prone to noise interference,which may lead to the presence of outliers.To overcome these limitations,a novel method that integrates optical informa-tion with array interferometric SAR(array-InSAR)for 3D imaging is proposed in this paper.The proposed method incor-porates the prior geometric information from optical images to constrain the SAR 3D reconstruction process,thereby ex-panding the data sources,reducing the cost of SAR data acquisition,and effectively correcting outliers.Specifically,the method first performs an initial 3D imaging process and establishes the registration relationship between the optical and SAR images using the initial 3D point cloud.The optical image is then segmented based on its geometric structure,and the segmentation results are applied as a constraint during the SAR reconstruction.Finally,the 3D reconstruction re-sults,constrained by geometric information,are obtained.The validation using the measured data demonstrates that the proposed method significantly reduces outlier scatter points in the 3D reconstruction,resulting in high-quality 3D point clouds that simultaneously incorporate optical and SAR textures.This approach shows promise in addressing the chal-lenges of heterogeneity encountered in the fusion of optical and SAR two-dimensional(2D)images,providing a solid foundation for subsequent target interpretation based on the fused images.关键词
