Vision targets tyres

Cognex Corporation has introduced two systems for automatically identifying tyres and wheels.

The first system is the TIS-8000 Tyre Identification System. This provides in-process verification and identification of tyres using specialised machine vision software that recognises tyre treads and sidewalls. Common applications include tracking and sorting tyres during manufacturing, verifying the correct tyre models prior to mounting onto wheels, and ensuring the correct sequence of tyres prior to shipping.

The second system, the WIS-8000 Wheel Identification System, automatically recognises wheel spoke patterns, wheel finish, and other features to ensure the presence of correct wheels. Common applications include identifying wheels prior to balancing and ensuring that the correct wheels are paired with the correct tyres for a particular vehicle.

The TIS-8000 and WIS-8000 systems use Cognex’s PatMax geometric pattern matching technology. The technology, which has several patents pending, recognises specific part features – such as treads and spoke patterns – despite variations in part position, scale, or appearance.

The TIS-8000 and WIS-8000 identification systems are equipped with a Cognex PC-based machine vision frame grabber, Sony XC-55 camera kit, identification and verification application software, network connectivity software, and specifications for lighting and light booth construction.
