Description
Technical field
The present invention relates to electronic field more particularly to a kind of dining room payment systems based on recognition of face.
Background technique
In some large and medium-sized enterprises, public institution (such as hospital, school), factory, business premises or industrial park,
It is designed with internal dining room, facilitates the life of employee, provides welfare for employee.Most of the payment system in existing dining room is to pass through
First supplement the payment management mode of brush IC card payment with money.It is mainly employee and a small number of visitors or outer in the consumer group in dining room
Carry out personnel.For employee, employing unit has the welfare of various criterion；It, will be by enterprise or list for the visitor of public affair reception
It is received by dining standard position；For other visitors, visitor oneself is needed to pay dining expense.
Currently, in actual use, the dinning card of employee, which is easy to appear, to be falsely used or for brush, the more people's consumption of a card,
To waste the welfare that employee gives in employing unit.For belonging to the visitor of public affair reception, host organization is desired with accurately
Ground records have dinner personnel and reception department, avoids public affair reception from being abused, causes unnecessary extravagance and waste.And oneself is paid
The visitor's consumption taken, it would be desirable that capable of having dinner, it is quick and conveniently to pay.It is existing meeting therefore, it is necessary to a kind of new means of payment
On the basis of having payment function, it can fundamentally prevent other people and falsely use or for brush dinning card phenomenon, to avoid wasting, save
About cost, payment flow mode are more accurate, convenient and quick.
Summary of the invention
In view of the foregoing deficiencies of prior art, the present invention provides a kind of dining room payment system based on recognition of face,
To solve the above technical problems.
Dining room payment system provided by the invention based on recognition of face, comprising:

In the present embodiment, further include input module, the password of number and letter composition can be inputted by input module,
Input module can use the keyboard input structure of entity, can also be using input structures such as touch screens, in the present embodiment, branch
The process paid can be carried out using two different modes:
Mode one:
S11 according to all-in-one machine identify as a result,
If recognition result is registration user, user is reminded to input password:
If password authentification is correct, display screen shows that user information, payment system are deducted fees, and shows this consumption gold
Volume and remaining sum.
If password authentification mistake, selected from face recognition result similarity meet the top N user of recognition threshold into
Row password match, the if it exists correct user of password match, then the display screen display correct user information of password match, payment are
System is deducted fees, and shows this spending amount and remaining sum；If all user passwords cannot match, consumption not can be carried out.
S12 not can be carried out " brush face " consumption and payment then if nonregistered user.
Mode two:
S21 reminds user to input password first；
S22 finds the user of registration by password match, establishes and identifies small library, then carries out recognition of face in small library；
S23 face recognition result meets recognition threshold, selects the user of highest similarity threshold value for final recognition result, shows
Display screen shows user information, and payment system is deducted fees, and shows this spending amount and remaining sum；
S24 face recognition result is unsatisfactory for recognition threshold, not can be carried out brush face consumption and payment.
After payment process, the information of charging can be shown on all-in-one machine by communication module.The information of statistics can also
To be accessed according to the instruction of user, and it is shown on all-in-one machine.
As shown in Fig. 2, in this example it is shown that unit include the first display module 1 and the second display module 2, it is described
The display screen of the display screen of first display module 1 and the second display module 2 is backwards to being arranged, using the first display module 1 and second
Display module 2 carries out shuangping san, is set backwards by the display screen of the display screen and the second display module 2 of the first display module 1
It sets, consumer can be made to see a screen, staff sees a screen, it is preferable that can be to set between display module back and shell
It is equipped with movable part, by using the mode of flexible connection, in order to carry out angular adjustment.
In the present embodiment, further include the second verifying for carrying out secondary verifying when the first authentication unit authentication failed
Unit, second authentication unit include IC card identification module, and the IC card identification module is connect with control unit.
In the present embodiment, In vivo detection module includes three-dimensional image pickup device, binocular camera shooting device, near-infrared detection apparatus
Or the combination of one or more of action command living body detection device, In vivo detection module are mainly used to the image of detection acquisition
It whether is true man, to prevent malicious person from forging and stealing other people biological characteristic for authentication, by In vivo detection function,
Judge whether the biological characteristic submitted comes from lived individual, action command living body detection device can use recognition of face skill
The current In vivo detection technology of art is generally by the way of instruction action cooperation, such as face turns left, turns right, opens one's mouth, blinks, and refers to
Cooperation mistake is enabled then to be considered to forge deception.Only infrared detecting device be based on optical flow method and realize, without instruct cooperation, detection at
Power is higher.According to optical flow method, determined respectively using the time domain variation and correlation of the pixel intensity data in image sequence
" movement " of location of pixels.Three-dimensional image pickup device can use 3D camera shooting face, obtain the 3D of corresponding human face region
Data, and be further analyzed based on these data, finally judge that this face is from living body or non-living body.It is based on
The 3D human face data of living body and non-living body selects the feature of most discrimination to train classifier, utilizes trained classification
Device distinguishes living body and non-living body.The feature of selection had both included global information, also contained local information, such feature
Be conducive to the stability and robustness of algorithm.Binocular camera is special based on skin material specific to multispectral technology and face
Sign.Under the irradiation of multispectral light source, collected real human face material and various forgery face materials can be in special cameras
It is middle apparent difference occur.This species diversity can be quantified by image processing techniques and machine learning method.Utilize depth
Mode of learning allows computer that can independently judge whether sample to be detected is real human face, to reach the work of prosthetic supervision
The purpose that physical examination is surveyed.
