Research and Application of Data Preprocessing of Highway Slope Deformation Monitoring System

Deformation extraction of building facade using ground-based interferometric synthetic aperture radar assisted by 3D laser scanning technology

“…The corresponding point cloud slant range projection coordinates can be calculated using (4). Compared to the reference in [13], utilizing (3) or (5) can make it easier to analyze the deviation effects of pitch angle ω and side inclination angle κ on point cloud slant range projection.…”

“…It is challenging to fully exploit the performance of satellite-borne InSAR technology in localized small-area scenes on the ground surface as well as in monitoring applications of special deformation directions due to the limitations of side-view angle, spatial resolution, and revisit period of satellite-borne SAR sensors. The advent of Ground-based Synthetic Aperture Radar Interferometry (GB-InSAR) technology has introduced a novel approach for high-precision surface deformation monitoring and analysis in these specialized scenarios [1][2][3][4]. After more than two decades of development, GB-InSAR technology is now progressively moving from the experimental validation stage to the stage of core technological improvement, engineering structure, and geohazard monitoring application promotion.…”

Research on structural health monitoring methods for bridge structures

“…In the past, bridge health monitoring methods mainly included convergence instrument, level instrument, total station instrument, etc. [5][6][7]. Although these methods are more practical, they cost a lot of manpower and material resources and are not cost-effective [8][9].…”
