基于序贯InSAR技术的建筑物形变监测方法
Building Deformation Monitoring Method Based on Sequential InSAR Technology
摘要
Abstract
To meet the demands for continuous and accurate monitoring of urban buildings,we proposed a rapid and reliable building deformation monitoring method by integrating sequential adjustment with multi-temporal interferometric synthetic aperture radar(MT-InSAR)technology,which employed a two-stage adaptive filtering to mitigate the impact of noise on interferometric image pairs.We used MT-InSAR to obtain the deformation parameters of existing images,and used sequential adjustment for the overall solution,significantly enhancing computational efficiency.We used 50 Sentinel-1 images acquired over Fuyang from November 1,2022,to July 11,2024,to compare sequential InSAR with traditional MT-InSAR techniques.Results demonstrate that both methods yield consistent surface deformation monitoring outcomes,with root mean square errors of deformation speeds and cumulative displacements within the sub-millimeter range.Moreover,the sequential InSAR method reduces computational time by 51.891 9%compared to the traditional approach.Continuous monitoring of urban building deformation by sequential InSAR method is conducive to the urban safety risk evaluation.关键词
