Description
Technical field
The present invention relates to a kind of schemes that can expand recognition of face number of users, belong to third generation biological identification technology neck
Domain.
Background technology
In the prior art, it is most of using card managing, it is more advanced to be verified using biotechnology
Management, and recognition of face biotechnology has just developed in this field.Recognition of face is one kind of recognition of face, belongs to biological knowledge
Not, face identification system is exactly to obtain personal face distribution map by face recognition instrument first, from face distribution map according to special
Alignment algorithm extracts characteristic value, and the image of face is obtained by camera, the digital picture of face is stored in computer system
In, characteristic value is stored.During face alignment, face figure is taken in real time, extracts characteristic value, with advanced filtering, image two-value
Change, refine means to digital image zooming-out feature, compared with face characteristic value in host is stored in, using complicated matching algorithm
Face characteristic is matched, so as to carry out identity authentication to individual, confirms identity.
When carrying out authentication with face, acquisition be face characteristics of image, refer to feature existing for ability during live body.
In the system, the face of non-living body is to cannot get facial image feature, thus None- identified, so as to also can not just fake.With
When face carries out authentication, acquisition be facial image feature inside face rather than face surface characteristics of image.Cause
This, there is no any due to the damage on face surface, abrasion, drying or the cognitive disorders brought such as overly wet.Body is carried out with face
Part certification, when obtaining face facial image, face need not be contacted with equipment, gently one be put, you can complete identification.This mode does not have
There are antihygienic problem during hand contact arrangement and face surface characteristics that may be replicated caused safety problem, and avoid
The Psychological inadaptability for examining object is taken as, while will not because of None- identified after dirt contamination.User's acceptance is good.Except nothing
Beyond need to being contacted directly with scanner surface, the scanning process of this Noninvasive is not only simple but also naturally, alleviates user
The resisting psychology that may be present due to worry sanitation degree or using trouble.Because there are the vivo identification of front, internal spy
The feature for contactless 3 aspects of seeking peace, it is ensured that the palm feature of user is difficult to be forged.So face identification system is safe
Grade is high, and the place high particularly suitable for safety requirements uses.But it there is problems in the prior art to be solved： (1)
Belong to interior physiological characteristic, will not wear, it is more difficult to forge, there is very high security.(2) blood vessel feature usually becomes apparent from, and easily distinguishes
Know, anti-interference is good.(3) non-contact measurement can be achieved, wholesomeness is good, is easy to receive for user.(4) it is not easy to be hindered by watch face
The influence of trace or greasy dirt.More than technology has the drawback that：Collecting device has particular/special requirement, and design is relative complex, manufactures cost
It is high.
CPU card：Also referred to as smart card, with microprocessor CPU, storage unit and chip behaviour in the integrated circuit in card
Make system COS.CPU card equipped with COS is equivalent to a microcomputer, not only with data storage function, while has life
The functions such as order processing and data security protecting.CPU card is applicable to the multiple fields such as finance, insurance, traffic police, government industry, tool
There is the user's space big（Human face data can be stored）, reading speed is fast, supports the features such as one card for multiple uses, and passed through Chinese people
Bank and the certification of national ministries and commissions.
The content of the invention
The purpose of the present invention.
The present invention proposes a kind of side that can expand recognition of face number of users to improve the safety coefficient of access control system
Case.
The technical solution adopted in the present invention.

It identifies and is controlled the logic communication between circuit, cortex A8 more thans arm processor configuration camera, visitor is into pedestrian
Face image is extracted and digitized processing, wherein recognition of face follow the steps below：
The first step, training and projection facial image obtain the facial image of five candidates by the matching of grader, and training obtains
Optimized image feature
Optimal test image is found in five candidate face images in second step, grader：
3rd step is counted out to determine verification criterion by matching key, and it is most that setting, which matches maximum face descriptor of counting out,
Possible item by characteristic matching, obtains target facial image.
Then, by CPU card reader, face characteristic data are stored onto CPU card, every time when identification, from CPU card
Upper reading face characteristic data, in this way, can be with the number of users of infinite expanding recognition of face, it is ensured that recognition of face adapts to various
Identify place.
