This plugin has an experimental version available!
LasBuildSeg is an automated processing pipeline and Python library designed for extracting accurate building footprints from LiDAR point cloud data (.las/.laz format). Key Features & Workflow: • Automatically calculates adaptive height and TRI (Terrain Ruggedness Index) thresholds based on coarse-scale nDHM analysis. • Utilizes CSF (Cloth Simulation Filter) for robust ground filtering and DTM generation. • Implements morphological opening and FXAA-style edge smoothing for noise reduction. • Offers advanced false-positive elimination tools, including height variance, convex hull ratio, and elongation filters. • Supports per-connected-component alpha shape extraction to prevent vegetation merging and deliver crisp building boundaries. • Exports ready-to-use vector footprints reprojected into Web Mercator (EPSG:3857) alongside debug layers for threshold tuning.
