Description
Technical field
The present invention relates to the member system systems of iris recognition, belong to third generation technical field of biometric identification.
Background technique
Member card management system is the meeting for the exploitation of the industry situations such as chain special counter, brand shop, store, consumer entertainment place
Member's comprehensive management platform develops member system based on member card marketing mode, and multi-functional member card function can help to look forward to
Industry expands the consumer group, and cash register member card management, is integrated, supplemented with money, member's analysis integrated management, is disappeared by system to member
Take the analysis of data, the data informations such as the high product of loyalty and the high member of the level of consumption, sales volume is obtained, so as to administrative staff
Dynamic and market strategy is scientifically adjusted, promotes the enhancing of corporate member's loyalty, product category optimization, increases corporate sales volume
And profit.Member card management system is to corporate member's basic document, consumption, integral, Stored Value, promotion and preferential policy through letter
Breath management, reaches businessman and client and keeps good connection at any time, to allow client's Double Spending, improves customer loyalty, real
The purpose that existing achievement increases.Member card management system also has other than membership promotion abundant and member card management function
Member's all-purpose card function provides a variety of member card functions, and such as member card consumption, member card is supplemented with money, member card gives a discount, member card
Integral, the modification of member card accumulated point exchanging, member card rebating, member's clip pin, the management of member card account, member card transfer accounts, member card
It the functions such as checks account, really embodies the one card for multiple uses of member's card software, the characteristics of all-purpose card is used.Meanwhile enterprise can pass through meeting
Member's card system carries out comprehensive management to member, enterprise can understand at any time shops, member, member card consumption, side
It helps enterprise to mitigate terminal management difficulty, effectively carries out member system marketing.
In the prior art, most of using card managing, it is more advanced to be verified using biotechnology
Management, and iris recognition biotechnology has just developed in this field.When carrying out authentication with iris, acquisition is iris
Characteristics of image, feature existing for ability when referring to living body.Within the system, the eye eye of non-living body is to cannot get iris image spy
Sign, thus can not identify, to also can not just fake.When carrying out authentication with iris, acquisition is rainbow inside eye
Film image feature, rather than the characteristics of image of eye surface.Thus, there is no any due to the damage of eye surface, abrasion, does
The brings cognitive disorders such as dry or overly wet.Authentication is carried out with iris, and when obtaining eye iris image, eye eye need not be with
Equipment contact, gently one puts, identification can be completed.Antihygienic problem and eye when this mode does not have an eye contact arrangement
Portion's eye surface feature may be replicated brought safety problem, and avoid the Psychological inadaptability for being taken as and examining object, together
When will not be because that can not be identified after dirt contamination.Iris recognition mode is located inside of eye, the external factor such as temperature due to iris
Influence degree can be ignored, be suitable for almost all users.User's acceptance is good.In addition to without being sent out with scanner surface
Other than raw directly contact, the scanning process of this Noninvasive is not only simple but also naturally, alleviates user due to worrying sanitation degree
Or using trouble and resisting psychology that may be present.Because having vivo identification, internal feature and contactless 3 sides of front
The feature in face, it is ensured that the iris feature of user is difficult to be forged.So iris authentication system security level is high, it is particularly suitable for
It is used in the high place of safety requirements.There is also following advantages compared to the prior art: (1) belonging to interior physiological characteristic, will not grind
Damage, it is more difficult to forge, there is very high security.(2) blood vessel feature usually becomes apparent from, recognizable, and anti-interference is good.It (3) can be real
Existing non-contact measurement, wholesomeness is good, is easy to as user's receiving.The above technology has the drawback that: acquisition equipment has special want
It asks, designs relative complex, manufacturing cost height.
Summary of the invention
The purpose of the present invention.
The present invention is exactly the difference for employee and visitor, allows employee using iris, visitor is checked card using identity card, and is mentioned
The member system system of iris recognition out.
The technical solution adopted in the present invention.

Circuit, the above arm processor of cortex A8, LCD display circuit, LCD display, audio output circuit, loudspeaker, RS232/485
Conversion circuit, access controller are communicated, power supply is connected by power driving circuit with the above arm processor of cortex A8, iris
Acquisition Circuit is connected with the above arm processor of cortex A8, and SD card passes through at SD card interface circuit and the above ARM of cortex A8
Device to be managed to be connected, intercommunication visual information is transferred to LCD display by LCD display circuit by the above arm processor of cortex A8,
Audio prompt is spread out of by loudspeaker by audio output circuit, the above arm processor of cortex A8 is to iris recognition and circuit
Between logic communication controlled, the above arm processor of cortex A8 configures near infrared light led camera, carries out iris figure
As extraction and digitized processing, wherein iris recognition is followed the steps below:
The first step, training and projection iris image obtain five candidate iris images by the matching of classifier, and training obtains
Optimized image feature；
Best test image is found in five candidate iris images in second step, classifier；
Third step is determined verifying criterion by matching key point number, and the setting maximum iris descriptor of match point number is most
Possible item obtains target iris image by characteristic matching.
Preferably, the power module: the DC power supply of 12V is provided for access controller circuit system；Ethernet connects
Mouthful: it is responsible for the information transmission of remote network control, while provides downstream interface for intelligent domestic gateway；Voice module: according to rainbow
Film recognition result and access control information, to disengaging, personnel issue voice reminder information；Push-button interface: opening the door, it is true to request and open the door
The push-botton operation recognized sends low and high level signal by I/O interface.
Preferably, the voicefrequency circuit mainly includes that audio outputs and inputs processing circuit.Due to audio output signal
It is the analog signal that voltage is more than ten millivolts, thus power amplifier need to be first passed through and carry out gain adjustment, and A/D conversion circuit is turned
