Patent ID: 10699420

Abstract:
An eyeball tracking method and apparatus, and a device. The method comprises: acquiring a facial grey-scale image set to be detected (101); judging whether the contour of an eyeball iris is determined in an N-th frame facial grey-scale image in the facial grey-scale image set to be detected (102); if not, detecting an eyeball pupil in the N-th frame facial grey-scale image, and determining the central position of the eyeball pupil in the N-th frame facial grey-scale image (103); in the N-th frame facial grey-scale image, taking the central position of the eyeball pupil as a centre to determine a grey-scale image region corresponding to an eyeball window (104); and according to the grey-scale image region corresponding to the eyeball window, determining the contour of the eyeball iris in the N-th frame facial grey-scale image (105). By judging that the contour of an eyeball iris is not determined in a facial grey-scale image, the tracking of the contour of the eyeball iris can be automatically adjusted, and an eyeball pupil is positioned again. By means of the present invention, the accuracy rate of eyeball tracking is improved, and an eyeball can be automatically identified to detect the central position of an eyeball pupil.
