What the processing of image and the technical characteristic for being related to method than equity were all made of is the prior art, is not belonging to the utility model and is protected
Range
Fig. 2 is the system architecture diagram based on the access control system for referring to hand vein recognition in the utility model specific embodiment.At this
In utility model specific embodiment, finger vein machine, gate inhibition's host, data server are included based on the access control system for referring to hand vein recognition
And IOT client, wherein refer to that vein machine connects gate inhibition's host by RS485 bus, and by Ethernet through Ethernet exchanging
Machine wireless connection data server, gate inhibition's host connect data server and IOT client through Ethernet switch by Ethernet
End, its working principles are as follows:
When gate inhibition's unlock to be carried out, finger is placed in by user first refers to vein machine, so that finger is located at ccd image biography
On sensor and it is located under near-infrared LED, near-infrared LED projects infrared ray to finger, after part infrared ray can penetrate finger
It is received by ccd sensor.Since, there are red blood cell, red blood cell can absorb infrared ray, therefore near-infrared LED lamp is downward in finger
Infrared ray and after finger is projected, in the image that ccd sensor captures, black is presented at the vessel position in finger, and
Image at non-vascular position is then shown as white, and the finger vein image that final ccd sensor captures is the double-colored display of black and white
Flat image.Because there is some difference for the vascular distribution or trend of everyone and every finger, ccd sensor
The finger vein image captured can become unique key with everyone as the image information for recognizing each user
Spoon.
After ccd image sensor captures finger venous image information, by the corresponding finger vein image data compression of user
It is sent to data server after encapsulation, data server decompression contracts after reading refers to vein compressed package, and user is referred to vein image
It is pre-stored with user and refers to that the data in intravenous data library are compared, it is more due to being stored in advance in finger intravenous data library
The finger vein image data of position user then refer to appointing in vein image data and finger intravenous data library when data server receives
One finger vein image can correspond to, then it is assumed that user authentication for the first time success.
When user authentication for the first time success, data server then will be proved to be successful for the first time information and be back to gate inhibition master
Machine refers to vein machine and IOT client to start secondary identity authentication, and the camera that gate inhibition's host can start front end at this time carries out
Facial image shooting, to obtain the facial image of active user, and is sent to IOT client for the facial image of acquisition, by IOT
Client carries out feature identification to the facial image of acquisition, and is compared with pre-stored face database, if compare at
Function then sends secondary identity authentication successful information and is back to gate inhibition's host, by gate inhibition's host access control unlock, if can not compare
Function, then it is counter to send secondary identity authentication failure information to gate inhibition's host, the prompt information that gate inhibition opens failure is issued by gate inhibition's host.
In conclusion a kind of access control system based on finger hand vein recognition of the utility model, which passes through to utilize, refers to that vein machine obtains hand
Refer to that vein verification information verifies the identity of user for the first time, and after being verified for the first time, the camera for starting front end is obtained
Facial image is taken, and identification is carried out to facial image by IOT client and is compared to realize secondary identity authentication, realizes one kind
Gate inhibition's technology that is highly reliable, highly-safe and being not easy replacement forgery.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Anyone skilled in the art can repair above-described embodiment under the spirit and scope without prejudice to the utility model
Decorations and change.Therefore, the rights protection scope of the utility model, should be as listed in the claims.
