Abstract: This disclosure provides a pupil localization method, a device, an apparatus and a storage medium. The method comprises: preprocessing a pupil image; generating a first projection curve and a second projection curve on horizontal and vertical axes of two-dimensional coordinate axes respectively according to the preprocessed image; determining a first pair of dividing points and a second pair of dividing points on the first projection curve and the second projection curve respectively according to a pre-configured threshold; and determining center coordinates of the pupil according to the first pair of dividing points and the second pair of dividing points. This disclosure obtains projection curves through a simple operation of the preprocessed image on the two-dimensional coordinate axes, and then intercepts the dividing point on the projection curves according to the preconfigured threshold to determine the center coordinates of the pupil.
