WIPO Patent Application WO/2021/082636
Kind Code:
A1
Abstract:
A region of interest detection method and apparatus, a computer-readable storage medium and a terminal device. The method comprises: acquiring an image of an eye to be detected (S101); detecting an eye key point in the image of the eye so as to obtain position information of each eye key point in the image of the eye (S102); calculating a gaze feature value according to the position information of each eye key point in the image of the eye (S103); and determining an eye region of interest according to the gaze feature value (S104). In this method, there is no need to use an expensive precision instrument, with image analysis processing instead being performed on the image of the eye, so as to calculate the gaze feature value according to the position information of the eye key points, and the eye region of interest can be determined thereby, such that the cost is greatly reduced, and the method can be applied more widely.
