­Hella has given details of the Opel Eye system for General Motors Europe's new Opel/Vauxhall Insignia, stating that it can read both speed-limit and no-passing signs and even notify drivers when speed restrictions have been lifted.

Depending on light conditions, the system begins to recognize and repeatedly read signs at 100 m (330 ft). It starts by focusing on circular patterns and then identifies the numbers inside them via contour comparison. If a picture matches an image of a road sign in the car’s software, the sign is displayed in the instrument panel.

“On German highways, lanes sometimes have different speed limits,” said Dr. Christoph Schmidt, Engineering Group Manager of GME Electronics. "The Opel Eye is able to correctly register the relevant one every time."

The system displays the most relevant information for safe driving. If two signs are recognized in close proximity to one another, the most safety-critical takes precedence.

The notices are displayed for a few seconds as a symbol in the center of the instrument panel. In addition, drivers can recall the image by pressing a button on the steering wheel.

Opel Eye gives more accurate information than portable navigation systems with stored speed limits because the camera works in real time. If a speed limit changes, for example due to road construction, Opel Eye detects it.

The processors are able to recognize traffic signs because most are designed uniformly in line with the Vienna Convention on Road Signs and Signals. Established in 1968, the agreement has standardized road signs in more than 80 countries.
