Embodiment Construction

[0053] See figure 1 , the anti-counterfeiting iris identity authentication method for smart glasses of the present invention includes the following steps: (1) in the initialization stage of the user smart glasses, extract the user's eye images under different lighting environments as a reference image, extract and save the reference image The user's iris feature is used as the reference iris feature;

[0054] (2) On the basis of ambient light, a random sequence of incident light intensity changes is generated to stimulate the user's eyes to make the pupils shrink accordingly. At the same time, dynamic user eye images are collected at intervals of 0.1s to obtain a The eye image sequence that changes and changes, and simultaneously extract and save the user's iris feature in each dynamic eye image of the user as the iris feature to be tested;

[0055] (3) In step (2), the pupil diameter in each of the user's dynamic eye images collected while extracting the user's iris feature...

Abstract

The invention provides an anti-fake iris identity authentication method used for intelligent glasses. According to the method, requirements for periphery devices are low, multiple faking methods can be detected, and the high-adaptability anti-fake purpose is achieved. The method comprises the steps of (1) extracting standard images and saving user iris characteristics in the standard images as standard iris characteristics; (2) generating a random incident light intensity change sequence based on ambient light to stimulate the eyes of a user, collecting a dynamic user eye image, obtaining an eye image sequence, and extracting and saving user iris characteristics in the dynamic eye image as iris characteristics to be detected; (3) obtaining a pupil diameter change sequence through the dynamic user eye image and calculating the matching rate Pass1 between the pupil diameter change sequence and the incident light intensity change sequence; (4) selecting an image to be authenticated from the dynamic user eye image, selecting a comparison standard image from the standard images, and calculating the matching rate Pass2 of the iris characteristics of the image to be authenticated and the iris characteristics of the comparison standard image; (5) obtaining an authentication result according to the Pass1 and the Pass2.

Description

technical field [0001] The invention relates to the field, in particular to an anti-counterfeiting iris identity authentication method for smart glasses. Background technique [0002] Forrester Research, an independent technology market research organization, pointed out in a report "Smart Body, Smart World" that the next computing revolution will be wearable devices wrapped in sensors, rather than smartphones and tablets. Wearable computing equipment refers to the technology of "wearing" computers on the body. Its concept was first proposed in 1955. The original intention was to collect and predict live data in real time in the "roulette" gambling game. In 1991, Carnegie Mellon University (CMU) in the United States developed the wearable computer VuMen1 for engineering maintenance, which consists of a tiny computer and glasses-like display; "Warrior" inherited and developed the architecture of VuMen1, and added a network communication module on the basis of computers and g...
