Purpose.
S402, the shooting of 2D facial image is carried out to match the 2D facial image with 2D facial image template；
Optionally, in a kind of application scenarios, in order to improve the shooting quality of 2D facial image, based on progress 2D face figure
When as shooting, narrowband infrared beam is provided to illuminate face, and then carry out the shooting of 2D facial image.
Further, narrowband infrared beam can be provided by above-mentioned washers, be provided highly diffuse, not properly
To light rather than clear-cut light beam, be particularly suitable for shooting 2D facial image in the case of light environment is poor.
The present embodiment, in order to reduce the power consumption of Image Acquisition, in step 402A, human body is incuded by range sensor
At a distance from door body, to be carried out according to the distance controlling infrared image sensor time for exposure of 2D man face image acquiring, and
Reduce the time of acquisition 2D facial image, improves the performance of system entirety.
S403, judge whether the 2D facial image matches with 2D facial image template；
S404, structure light progress 3D face figure is based on when the 2D facial image and the success of 2D facial image template matching
As shooting is to match the 3D facial image with 3D facial image template；
In the present embodiment, as previously mentioned, if locally carrying out 2D recognition of face, identity legitimacy authentication device packet in door lock
Memory is included, 2D facial image template is stored on the memory, which is infused by face template
Volume process obtains.
If the 2D facial image and the success of 2D facial image template matching tentatively show that the identity of human body living body is closed
Method.
In the present embodiment, when carrying out the shooting of 3D facial image in step s 404, lattice structure light is provided and forms speckle knot
Structure light projects face, and then carries out the shooting of 3D facial image.In the present embodiment, when the 2D facial image and 2D facial image
When template matching is unsuccessful, then tentatively show that human body living body does not have the permission by gate inhibition channel, still, not assert certain
It is illegal.In addition, the 3D facial image shooting based on lattice structure light is increased, thus further progress people in the present embodiment
The anti-counterfeit recognition of face, by the matching of the 3D facial image and 3D facial image template, thus further determine whether illegally,
To improve the accuracy of identity legitimacy certification.
Herein, there is no the restriction of uniqueness for structure light, be actually also possible to coded structured light or fringe structure light.
The present embodiment, in step 404, human body is incuded at a distance from door body by range sensor, according to
Distance controlling infrared image sensor carry out 3D man face image acquiring time for exposure, and reduce acquisition 3D facial image when
Between, improve the performance of system entirety.
Herein, it should be noted that carry out the infrared image sensor of 2D man face image acquiring and 3D man face image acquiring
It can share, can also be separately configured.
S405, judge whether the 3D facial image matches with 3D facial image template；
When the 3D facial image and 3D facial image template matching it is unsuccessful when, alternatively, when the 2D facial image with
When 2D facial image template matching is unsuccessful, following steps S406 is executed；
S406, the video for recording field range；
In the present embodiment, the video of field range is recorded in step S406, comprising: carry out based on infrared induction structure light black
The recording of white video, and/or, the recording of color video is carried out based on RGB three primary colors structure light.
S406B, door lock driver driving gate is controlled when the 3D facial image and the success of 3D facial image template matching
Lock unlock；
S407, the video of recording is uploaded onto the server to be sent to front end by the server and verify, and received
The control instruction that the front end issues is to control the driving door lock unlock of door lock driver or keep locking.
Herein, it should be noted that if show that human body living body is illegal by 3D recognition of face, whether opening gate
Permission just gives artificial control, which realizes especially by the APP in front portion, if in front end
On APP, the administrator of gate inhibition thinks that gate inhibition can be opened, then operation generates a remote control commands to service on front-end A PP
The remote control commands are sent to embeded processor again by device, the server, thus the opening of access control.
Specifically, the interaction between access control system and front end is realized by wireless network module, wireless network module ratio
As wifi module is connected to home router.
Herein, it should be noted that the access control system in above-described embodiment, including the various channels that can be passed through, including
The current door of people, the door etc. of vehicle pass-through.Such as bank, hotel, parking lot management, computer room, armory, safe care registry, cubicle, intelligence
Change cell, factory etc..
Herein, it should be noted that be in the 2D facial image and 2D facial image template matching in Fig. 4 embodiment
The shooting of 3D facial image and matching are carried out after success.But in other embodiments, carrying out the shooting of 3D facial image
And matching can also be independent of the 2D facial image and the successful court verdict of 2D facial image template matching, it can also
It is accordingly, subsequent to work as the 2D facial image and 2D facial image template to be parallel to the shooting of 2D facial image and matching
With success and the 3D facial image and the success of 3D facial image template matching, then the driving door lock unlock of door lock driver is controlled.
