The 3D laser scanner gets mounted on the top of the stacker/ reclaimer machine and scans the entire stockpile to provide a real time 3D Profile and Volume of the stockyard as the machine is in operation, thus allowing for accurate inventory management with real time volume, Mass and 3D profile of the stockpile. The system can further be extended to provide anti-collision, yard management, and completely manless machine operation. Our Stacker / Reclaimer Machine mounted Laser Scanners with an association with Triple-In, Germany and Lynx Process, Brazil is in operation in the biggest iron ore mine in the World that is Carajas Vale, Brazil for Providing1. Volume and 3D Profile of the Stockpile in Real Time Dynamically 3D Laser Type 2. Anti- Collision of the Machinery 3. Material Tracking on the Belts4. Quality Report (Different grades of Coal marked with different colour on the stockpile).5. Manless Operation of the Stacker Machine where 1 operator can control 6-8 machines and movement of machine happens without any manual intervention 6. Complete Yard Management System The 3D laser scanner gets mounted on the top of the stacker machine  to give real time 3D Profile and Volume of the Stockyard as the machine is in operation, thus allowing for accurate inventory management with real time Volume, Mass and 3D Profile of the Stockpile.
