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 a plurality of lines at multiple angles representative of the detected edges. The processor determines the state of eye closure, such as eye open or eye closed, based on the number of lines at selected angles. The system may be employed on a vehicle to determine the eye closure of a driver of the vehicle.
Claims19
A system for monitoring an eye and determining eye closure, said system comprising:
- a video imaging camera oriented to generate images of an eye;
- and
- a video processor for processing the images generated with the video imaging camera, said video processor comprising an edge detector for detecting edges of the eye in the image and a line selector for selecting a plurality of lines representative of the detected edges at multiple selected angles, said processor determining a state of eye closure based on the number of said lines at selected angles.
A vehicle eye monitoring system for monitoring an eye of a person in a vehicle and determining eye closure, said system comprising:
- a video imaging camera located on a vehicle and oriented to generate images of an eye of a person in the vehicle;
- and
- a video processor for processing the images generated with the video imaging camera, said video processor comprising an edge detector for detecting edges of the eye in the image and a line selector for selecting a plurality of lines representative of the detected edges at multiple angles, said processor determining a state of eye closure based on the number of said lines at selected angles.
A method of monitoring an eye and determining eye closure, said method comprising the steps of:
- arranging a video imaging camera to generate images of an eye;
- generating an image of the eye;
- processing the image to identify edges of the eye in the image;
- generating a plurality of lines representative of the edges at multiple selected angles;
- and
- determining an eye closure state based on the number of said lines at selected angles.
