Industry Applications

Karst cave, no light, no signal, no existing topographic maps

Transform inaccessible, hard-to-survey caves into digitized archives.

Gob areas and roadways; no GNSS signal; lighting moves with the working face.

Keep personnel away from hazardous areas. Periodically compare roadway deformation and support status for early warning.

Underground civil air defense structure with dense beams, columns, and piping; unstable signal.

Enable inspection and record creation across the entire space; transform hidden hazards into measurable, schedulable tasks for resolution.

Large-scale indoor building with high ceilings, complex structure, and dense equipment

Capture indoor 3D data quickly without scaffolding.

The cross-section of the integrated duct is approximately 2–3 m wide, with utilities routed along the walls and limited lighting.

Zero personnel entry; precise and traceable defect locations; significantly improved per-kilometer file creation efficiency

The tunnel lining is a semi-circular concrete shell with no natural light and weak signal inside.

Internal inspection without lane closure; defect locations automatically geocoded

Existing underground parking garage with dense column grids and high ceiling piping.

Short operational window: drones complete inspections rapidly.

Cement, mineral powder, and coal silos: wall wear and material levels are difficult to monitor visually.

Drones enter the warehouse for inspection without human entry; inventory levels and losses are quantifiable.

Silo: Grain surface height, flatness, and bridging position detection

Personnel entry logging, with in-warehouse status captured via imaging.

Box girder interior: narrow, elongated, enclosed, and unlit.

Drones fly in for inspections to detect hidden defects early.

Drainage Culvert/Box Culvert: Sediment Accumulation and Blockage Inspection

Personnel entering the culvert is hazardous. Drones traverse the culvert to quantify sediment accumulation.
