  • Patent number: 9020199
    Abstract: A secondary curve, the ends of which coincide with the inner corner and the outer corner of the eye, is determined successively, and the total of the edge values of the pixels overlapping the secondary curve is calculated as an evaluation value. Next, a characteristic curve is generated on the basis of data made up of the calculated evaluation value and the Y-coordinate of the intersection between the secondary curve and a straight line passing through the center of a line segment whose ends coincide with the inner corner and the outer corner of the eye. Then, the reference positions for the upper eyelid and the lower eyelid of the eye are set on the basis of the result of an attempt to detect a pixel group occurring because of the red-eye effect in a search area defined on the basis of peaks in the characteristic curve.

  • Patent number: 8824739
    Abstract: A lower eyelid search window (W2) matching the pixels constituting the edge of a lower eyelid is transformed so that the lower eyelid search window (W2) fits the pixels constituting the edge of the lower eyelid. Then, the position of the centroid of the transformed lower eyelid search window (W2) is set as the lower eyelid reference position. Consequently, the lower eyelid reference position can be accurately set even if the lower eyelid search window (W2) is different in shape from the edge of the lower eyelid. Then, it is possible to accurately detect the degree of opening of the eyes of a driver and thus accurately determine the degree of wakefulness of the driver.

  • Publication number: 20140126776
    Abstract: Distances between edges which are detected and paired from images which show a driver's face are computed sequentially. Based on a change in the computed distances, a low-probability candidate for a pair of eyelid edges is eliminated. The edge pairs ultimately remaining as a result thereof are detected as upper eyelid edge and lower eyelid edge pairings. It is thus possible to carry out a detection which takes into account not only a feature which is near to an eyelid edge, but also movement as an eyelid. Accordingly, it is possible to accurately detect edges of a driver's eyelids.

  • Patent number: 8498449
    Abstract: An eye part detecting device has an image input section (21) for acquiring a face image, an eyelid edge labeling section (24) for detecting upper eyelid candidates and lower eyelid candidates which satisfy predetermined conditions for upper eyelids or lower eyelids in the face image, and an eyelid determination section (27) for comparing combinations of the upper and lower eyelid candidates to determine the combination of the upper and lower eyelid candidates whose relation best satisfies a predetermined condition as the upper and lower eyelids. The eyelid edge labeling section (24) classifies the horizontal edges and vertical edges calculated by an edge calculating section (23) into the upper eyelid candidates and the lower eyelid candidates according to a degree of how well the predetermined conditions are satisfied.

  • Patent number: 8139819
    Abstract: A computer (30) obtains a facial image acquired by picking up an image of a person subjected to image pickup from a camera (10), and estimates a facial expression of the person subjected to image pickup based on the obtained facial image. Next, the computer obtains an eye open level of the person subjected to image pickup based on the facial image, and sets a threshold of the eye open level based on the estimated facial expression of the person subjected to image pickup. When the eye open level exceeds the threshold, the computer (30) determines that the eye of the person subjected to image pickup is opened. Moreover, when the eye open level does not exceed the threshold, the computer determines that the eye of the person subjected to image pickup is closed.
