Automated wheel handling systems are required to identify over thirty different wheel types and sizes without human intervention. Wheels are randomly orientated on conveyors with a small Data Matrix code marked directly on each wheel that is used for identification. The surface finishes of wheels makes reliable reading of these codes challenging for standard barcode readers.
Cognex tire solutions deliver robust, high-speed, wheel identification using propriety code-reading algorithms that are able to reliably locate codes despite random placement and orientation of wheels on the conveyor. Once the Data Matrix code is located, code reading algorithms adapt to any changes in code appearance caused by marking or contrast differences between the code and its background to achieve high read rates.
