Opel Eye

The innovative Opel Eye improves driving safety, reduces stress and can even prevent costly speeding tickets. Located between the windshield and the rear-view mirror, the Opel Eye aids drivers in two different ways: Traffic Sign Recognition function and Lane Departure Warning.

Traffic Sign Recognition reads speed limit- and no-passing signs and displays them on the instrument panel. Depending on light conditions, the system begins to recognize and repeatedly read signs at 100 meters. The system always displays the most relevant information for safe driving, filtering out many signs that may overwhelm drivers.

The information is displayed for a few seconds as a symbol in the center of the instrument panel between the main round dials. Drivers can recall the image any time by pressing a button on the steering wheel. Traffic Sign Detection can be activated via a sub-page in the car’s onboard computer menu.

Lane Departure Warning alerts drivers when they unintentionally stray out of their lane. This helps prevent a dangerous situation, such as a driver falling asleep at the wheel. Lane Departure Warning can be switched on or off via a button. When active, it warns the driver with an acoustic signal and a blinking icon on the instrument panel.

Lane Departure Warning uses a second signal processor and software to filter lines and longitudinal patterns at speeds above 50 km/h. This enables the system to recognize the traffic lane. By using specific algorithms that define the conditions in which alerts are given and by noticing steering wheel and turn-indicator movements – signaling an intentional lane change – the system is designed only to intervene at the appropriate moment.

Opel Eye Image Processing

The Opel Eye camera captures and refracts light rays on the lens. A sensor changes that image into electronic signals, just like the photo receptors in the human retina. An analog-to-digital convertor codes these signals into binary data, which is then compared with stored images of traffic signs. If the camera finds a match and recognizes a sign, the image pops up on the vehicle display. The accuracy and recognition rate therefore depends greatly upon how many images the system has saved in its memory – and how closely the road signs follow the standards laid out in the Vienna Convention on Road Signs and Signals.
