Applications of the LMS511-21100 Lite in Industry
- AGV/AMR and Outdoor Autonomous Vehicles: Provides accurate 2D scanning data with a range of up to 80 m, supporting environment perception, obstacle detection, positioning, and autonomous navigation for AGVs and AMRs in factories, warehouses, ports, and outdoor logistics areas.
- Area Monitoring and Object Detection: Used for non-safety monitoring of large areas to detect the presence and movement of vehicles, goods, and machinery. Suitable for container yards, outdoor warehouses, and production facilities.
- Material Level Measurement and Conveyor Monitoring: High accuracy of ±12 mm enables continuous level measurement of bulk materials in silos and tanks, as well as flow monitoring on outdoor conveyor belts.
- Logistics and Port Management: Supports vehicle access control, container positioning, cargo dimensioning, and process optimization in outdoor logistics thanks to its fog suppression capability and long-range performance.
- Object Classification and Identification: High scanning frequency allows collection of point cloud data for cargo classification, vehicle shape recognition, pallet detection, and object dimension measurement on automated production lines.
AUMI has supplied the LMS511-21100 Lite for numerous outdoor AGV projects, logistics monitoring systems, and warehouse management applications at manufacturing plants across Vietnam.
