Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 As shown, a kind of anti-cheating method by iris recognition provided by the present invention comprises:

[0014] A pre-stored database of people matched with iris features;

[0015] Before the tested person performs the drinking test, identity verification is first required, that is, the human eye needs to be identified through the iris test instrument, and M iris features of each tested human eye are obtained at the same time, and then the obtained iris features are compared with the The database is compared to obtain the information of the tested person;

[0016] In the process of identification, the iris tester always locks the eyes of the person. During the period after obtaining the information of the person under test and before obtaining the drinking information, the iris tester always tracks the eye...

Abstract

The invention provides a method for preventing cheating through iris recognition. The method comprises the steps of acquiring M iris characteristics of a tested person through an iris testing instrument, performing comparison with a database for acquiring information of the tested person; continuously tracking the eyes of the tested person by the iris testing instrument, and acquiring a leas N iris characteristics in each frame in a tracking process; in a time period between acquiring the information of the tested person and receiving the expired gas of the tested person for performing drinking testing, if the number of the continuous frames in which the iris characteristics cannot be acquired in the obtained image is larger than S, performing alarming or reminding the tested person of performing iris recognition testing again; and if the iris characteristics cannot be acquired or the number of the acquired iris characteristics is smaller than N in S continuous frames, determining no leaving of the tested person, and acquiring drinking testing information of the tested person. The method can realize in-time tracking for the iris of the tested person for preventing substitution in testing, and furthermore can judge whether substitution in testing occurs according to the iris recognition condition in the preset number of continuous frames.

Description

technical field [0001] The invention relates to a method for preventing cheating in drinking tests, in particular to a method for preventing cheating by train drivers through iris recognition. Background technique [0002] Alcohol testing by flight attendants is an important part of flight attendants leaving, leaving, and entering and exiting apartments. Due to fingerprint identification and other methods, there may be a situation where the tester himself leaves to let others take the test after the person is identified; and during the drinking test, there is also the phenomenon of proxy testing, because in the past, the alcohol tester only took pictures of the alcohol test at the moment of the alcohol test, and then specially took pictures afterwards. To prevent cheating by comparing the wine test photos with the standard photos of flight attendants, the real-time performance is poor and the workload is heavy. Contents of the invention [0003] The technical problem to b...
