ABSTRACT:
A system and method are provided for monitoring an eye to determine eye closure. The system includes a video imaging camera oriented to generate images of an eye. The system also includes a video processor for processing the images generated with the video imaging camera. The processor includes an edge detector for detecting edges of the eye in the image and a line selector for generating substantially horizontal first and second lines representative of the detected edges. The processor determines the state of eye closure, such as eye open or eye closed, based on distance between the first and second lines. The system may be employed on a vehicle to determine the eye closure of a driver of the vehicle.
