Patent ID: 11895404
Assignee: WORLDCOIN FOUNDATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. An iris scanning device, comprising:
a first camera that is configured to:
capture an image of a face of a user of the iris scanning device;

a second camera that is configured to:
capture an image of an eye of the user subsequent to the image of the face of the user being captured;

a gimbal having a mirror mounted thereon;
a facial feature detector that is configured to:
identify facial features of the user based upon the image of the face of the user, the facial features of the user comprise a predicted location of the eye of the user; and
compute a desired angle between the eye of the user and the mirror mounted on the gimbal based on the facial features of the user; and

control circuitry that is configured to:
subsequent to capture of the image of the face of the user, adjust an orientation of the gimbal based upon the facial features of the user such that an angle between the eye of the user and the mirror mounted on the gimbal is the desired angle, wherein the image of the eye of the user is captured upon the orientation of the gimbal being adjusted, wherein the mirror mounted on the gimbal is oriented to cause the image of the eye of the user to be captured;

wherein the facial feature detector is further configured to:
identify features of the eye of the user based upon the image of the eye of the user; and
determine whether the image of the eye of the user satisfies criteria based upon the features of the eye, wherein a code is generated based upon the image of the eye of the user when the image of the eye satisfies the criteria; and

wherein the control circuitry is further configured to:
adjust the orientation of the gimbal having the mirror mounted thereon based upon the features of the eye when the image of the eye of the user does not satisfy the criteria, wherein the mirror mounted on the gimbal is oriented to cause a second image of the eye of the user to be captured by the second camera upon the orientation being adjusted based upon the features of the eye.
