The embodiment of the invention discloses an identity identification method and device, equipment and a storage medium. The method comprises the following steps that: obtaining a
grey level histogramcorresponding to the
grey level image of an eye image; according to the
wave crest positions of a
pupil and an iris in the
grey level histogram, determining a first grey level threshold value, and according to the first grey level threshold value, determining an iris
mask image; according to the projection of the iris
mask image on a two-dimensional coordinate axis, determining
pupil parameters; if an internal and external eccentricity determined on the basis of the
pupil parameters is not greater than a preset eccentricity threshold value, according to the projection of the grey level image on the two-dimensional coordinate axis, and the first grey level threshold value, determining the internal boundary parameter of the iris; according to the internal boundary parameter, determining theiris external boundary parameter in the grey level image; and according to the internal boundary parameter and the external boundary parameter, determining an iris area in the grey level image, and carrying out identity identification on the basis of the iris area. By use of the method, the technical problem of poor identity identification means instantaneity on the basis of the iris in the priorart is solved, and the speed of identity identification based on the iris is improved.
