The scanning target is a metal mine goaf located approximately 650 meters underground. We conducted detailed and accurate scanning of the goaf and built a complete 3D model of the mine cavity, providing comprehensive data support for subsequent backfilling operations.
The mine features narrow passages, complex surroundings and crisscross routes. Long-term disuse has rendered some areas hazardous and inaccessible to conventional scanning equipment. Poor lighting and single access passages across m
