IRIS BIOMETRIC RECOGNITION MODULE AND ACCESS CONTROL ASSEMBLY

摘要

An iris biometric recognition module includes technology for capturing images of an iris of an eye of a person, whether the person is moving or stationary, and whether the person is located near the iris image capture device or at a distance from the iris image capture device. The iris biometric recognition technology can perform an iris matching procedure for, e.g., authentication or identity verification purposes. The iris biometric recognition module can be incorporated into, for example, a door lock assembly and other access controlled devices, mechanisms, and systems.

主权项

1. An iris biometric access control system comprising:
one or more non-transitory machine readable storage media, and, embodied in the one or more non-transitory machine readable storage media: an iris image capture module to
by a face imager, detect the presence of a human face in a capture zone defined at least in part by a field of view of the face imager;in response to detection of the human face in the capture zone, align a lens of an iris imager with an iris of the detected human face;operate an illuminator to illuminate the iris; andoperate the iris imager to produce a plurality of digital images; and an iris image processing and matching module to:
select one or more of the received iris images for matching;extract a usable portion from each of the selected iris images;compare the extracted portion of each of the selected iris images to a reference iris image; andin response to the comparison of the extracted portions of the selected images and the reference image, operate an access control mechanism.
