Researchers at the Fraunhofer Institute for Digital Media Technology in Germany are creating a vehicle-based system called Eyetracker that monitors a drivers face for signs of drowsiness. When certain patterns in eye and facial movements that indicate a lack of awareness are detected, the system triggers warnings to keep the driver alert. Debuting at the VISON trade fair in Stuttgart next month, the system is driven by two separate, small cameras mounted in the car, linked to a small matchbook-sized processor.
Professor Husar of the IDMT explains below:
“What we have developed is a small modular system with its own hardware and programs on board, so that the line of vision is computed directly within the camera itself. Since the Eyetracker is fitted with at least two cameras that record images stereoscopically – meaning in three dimensions – the system can easily identify the spatial position of the pupil and the line of vision.”
