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, and a video processor for processing the images. The processor includes an edge detector for detecting edges of the eye in the image, and a line selector for generating lines at any of select angles representative of the detected edges. The processor determines the state of eye closure, such as an open eye or closed eye, based on an angle between two of the lines that select angles. The system may be employed on a vehicle to determine the eye closure state of a driver of the vehicle.
