A system (30) and method (100) are provided for monitoring an eye (22) to determine eye closure. The system (30) includes a video imaging camera oriented to generate images of an eye (22), and a video processor (32) for processing the images. The processor (32) includes an edge detector (54) for detecting edges (80) of the eye (22) in the image, and a line selector (58) for generating lines (72, 74, 76) at any of select angles (Æ) representative of the detected edges (80). The processor (32) 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 (Æ). The system (30) may be employed on a vehicle (10) to determine the eye closure state of a driver (20) of the vehicle (10). |
