Vision Based Locating
De Vision Based Locating System works as follows:
- Optical Position Markers, OPM’s (2D matrix codes) are strung under the roof of the warehouse. Size and number of OPM’s are determined by the height of the roof.
- A vision sensor, mounted on the roof of the forklift truck, observes the OPM’s and determines position and orientation of the forktruck.
- The pallet is also identified by a vision sensor, mounted on the boom. Two other sensors determine the height of the fork, and the exact moment that a pallet is being picked up or put down.
- Software on the forktruck determines the new location in three dimensions and translates the X, Y, Z coordinates to a bin location, which is passed on to the server application, that communicates to WMS and/or ERP systems.
Mieloo & Alexander demonstrated earlier in 2013 in a test at Monsanto Antwerp on behalf of the Flanders Institute of Logistics, that the 100% location accuracy at floor and racklocations can be easily achieved with the Vision Based Locating System. All movements of pallets (but also big bags, pallet boxes, IBC’s, etc.) made with forklifts and palletjacks: goods receipt, put-away, internal movements, picking and goods issues, are registered automatically.
- Efficiency: no manual barcode scanning.
- 100% loading accuracy!
- 100% locating accuracy: no more Mancos or backorders, elimination of cycle counting.
- Safety: operators don’t have to get of their forktrucks to make manual scans.
- Transparency of warehouse processes: driving distances, routes chosen, ration between loaded/unloaded trips, etc.
