Supervoxel-based multi-level region growing method for surface point cloud extraction in intersecting tunnels

Mine intersecting tunnels are characterized by multi-directional connectivity, irregular surface morphology, and complex ancillary pipelines and facilities. Existing methods often fail to achieve complete extraction of tunnel surface point clouds. Therefore, this paper proposes a precise extraction method for interse...
