AI Technical Summary
Existing ground-penetrating radar (GPR) technologies struggle to accurately detect and map underground longitudinal structures like pipes due to clutter interference from soil reflections, which current methods either rely on inaccurate clutter modeling or degrade target signals during filtering, and are limited to 2D detection on uniform grids.
A method for detecting buried longitudinal structures using GPR that involves constructing a 3D point cloud from multiple radar acquisitions, filtering clutter by searching for substantially aligned points, and identifying lines in 3D space to characterize objects like pipes and conduits, without relying on statistical clutter modeling.
Effectively reduces clutter in 3D imaging, enabling accurate detection and mapping of underground structures by identifying spatially coherent reflections, improving the precision of GPR in locating pipes and conduits.
