Embodiment 1

[0027] An examination and certification system applied to big data iris recognition candidates, the hardware structure is installed at the entrance of the examination room, which includes an iris collector 10, an AD converter 11, a digital signal processing chip 3, a data storage 4, an ARM processor 12 and a release device 5. The iris collector 10 is connected to the AD converter 11 , and the iris image information collected by the iris collector 10 is input into the AD converter 11 and converted into a digital image. The AD converter 11 is connected to the digital signal processing chip 3 , and the iris image information converted by the AD converter 11 is transmitted to the digital signal processing chip 3 for processing. The digital signal processing chip 3 is connected to the ARM processor 12 , and the digital signal processing chip 3 transmits the results of image processing and identification analysis processing to the ARM processor 12 for control and management. The AR...

Embodiment 2

[0030] On the basis of the first embodiment, the iris collector 10 is IRISPASS, BM-ET300 or BM-ET500, and the front end of the lens of the iris collector 10 is installed with an infrared cutoff filter device. The infrared cut-off filter device can be used to filter out infrared light to collect a color image of the iris.

Embodiment 3

[0032] On the basis of Embodiment 1 or Embodiment 2, the AD converter 11 is an AD converter 11 of AD7705 produced by AD Company. AD7705 is an AD converter suitable for low frequency measurement instruments produced by AD company. It can directly convert the weak iris image information received from the iris collector 10 into a serial digital signal output without the need for an external instrumentation amplifier. And the AD7705 has achieved 16-bit error-free good performance, and the on-chip programmable amplifier can set the input signal gain. The first notch of the digital filter can be set by adjusting the turn-off time and update rate of the internal digital filter through on-chip control registers. With a +3V supply and a 1MHz master clock, the AD7705 consumes only 1mW. AD7705 is an ideal circuit based on microcontroller (MCU) and digital signal processor (DSP) system, which can further save cost, reduce volume and reduce system complexity. Applied to microprocessor (...

Abstract

The invention discloses an examinee examination authentication system applied to big data iris recognition, belongs to an examinee examination authentication system hardware structure in the technical field of identity authentication, and aims to provide the examinee examination authentication system hardware structure applied to the big data iris recognition. The examinee examination authentication system has the technical scheme that the examinee examination authentication system comprises an iris collector, an AD (Analog / Digital) converter, a digital signal processing chip, a data memory, an ARM (Advanced RISC Machines) processor and a releasing device, wherein the iris collector, the AD converter, the digital signal processing chip, the data memory, the ARM processor and the releasing device are arranged on an examination room entrance; the iris collector is connected with the digital signal processing chip through the AD converter; the digital signal processing chip is connected with the releasing device through the ARM processor; the data memory is connected with the digital signal processing chip; the iris image information collected by the iris collector is converted into a digital image through the AD converter, and the digital image is input into the digital signal processing chip to be processed; and the processed signal is input into the ARM processor to control the releasing device to be opened or closed.

Description

technical field [0001] The invention belongs to the technical field of identity authentication, and relates to a hardware structure of a candidate examination authentication system, in particular to a hardware structure applied to a big data iris recognition candidate examination authentication system. Background technique [0002] With the increase in the scale and number of various examinations year by year, although the examination management agencies have taken various measures to prevent them, they still cannot effectively eliminate the phenomenon of taking exams. The fairness and impartiality of examinations infringed the interests of examinees and disturbed the social order. At present, in all kinds of examinations, candidates enter the examination room with their admission tickets. The monitoring teacher can only judge whether the photos of the candidates on the admission tickets are consistent with the naked eye, and cannot guarantee the admission of impostor candid...
