ABSTRACT:
An eye detection method of a drowsy driving alarming system comprises the steps of: binarizing a driver's face image from a CCD camera, extracting candidate areas existing in pair into a binary face image, determining one candidate pair from among the candidate pairs as nostrils, setting the remained candidate pairs forming equilateral triangles in relation with the nostrils as eye candidate pairs, and determining a candidate pair forming the smaller equilateral triangle to be the driver's eyes.
