Dual-Module Bench-Line Extraction and Surface-Object Segmentation from UAV LiDAR Point Clouds in Open-Pit Mines Using Neighborhood Geometric Analysis and an Enhanced PointNet++ Network

Open-pit mines contain rapidly changing terrain, discontinuous bench structures, and mixed artificial–natural objects, which complicate automated three-dimensional mapping. This study presents a dual-module workflow for UAV LiDAR point clouds. Module A characterizes local geometry using normal and curvature descriptors...
