Eye Detection Method and System
First Claim
1. An eye detection method for detecting a degree of eye opening and closure of a testee, comprising:
- detecting a location of an eye pupil, a location of an inner eye corner and a location of an outer eye corner of an eye of the testee;
calculating an eye width according to the location of the inner eye corner and the location of the outer eye corner;
multiplying the eye width by a specific ratio to obtain an eye height;
generating a region of interest with a center on the location of the eye pupil, a length equal to the eye width, and a width equal to the eye height; and
determining a ratio of the eye occupying a detection area in the region of interest, and determining the degree of eye opening and closure of the testee accordingly.

Abstract
An eye detection method for detecting a degree of eye opening and closure of a testee includes detecting a location of an eye pupil, a location of an inner eye corner and a location of an outer eye corner of an eye of the testee; calculating an eye width according to the location of the inner eye corner and the location of the outer eye corner; multiplying the eye width by a specific ratio to obtain an eye height; generating a region of interest with a center on the location of the eye pupil, a length equal to the eye width, and a width equal to the eye height; and determining a ratio of the eye occupying a detection area in the region of interest, and determining the degree of eye opening and closure of the testee accordingly.

10. An eye detection system for detecting a degree of eye opening and closure of a testee, comprising:
-
a photography device, for detecting a location of an eye pupil, a location of an inner eye corner and a location of an outer eye corner of an eye of the testee; and a processor, coupled to the photography device, for performing the following steps; calculating an eye width according to the location of the inner eye corner and the location of the outer eye corner; multiplying the eye width by a specific ratio to obtain an eye height; generating a region of interest with a center on the location of the eye pupil, a length equal to the eye width, and a width equal to the eye height; and determining a ratio of the eye occupying a detection area in the region of interest, and determining the degree of eye opening and closure of the testee accordingly. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. An eye detection method for detecting a degree of eye opening and closure of a testee, comprising:
-
performing an image binarization on an eye image within a region of interest, to generate a binarized image having an eye region and a non-eye region; performing a filling process on the binarized image to eliminate a noise in the eye region determined to be the non-eye region; detecting an area of the eye region within a detection area in the region of interest after the filling process is accomplished; and determining that the eye of the testee is closed when a number of times the ratio of the eye region occupying the detection area smaller than a threshold value is detected in a specific period of time reaches a specific number.
