The following specific embodiment is in connection with above-mentioned accompanying drawing explanation the present invention.
The specific embodiment
As shown in Figure 1, be the applied environment schematic diagram of Intelligent pick-proof system of the present invention.In the present embodiment, this Intelligent pick-proof system 24 runs in security door 2.Described security door 2 also comprises that the camera head 20 that is connected with data wire by holding wire, actuating unit 21(are as power supply), safety device 22, memory 23 and processor 25.
Consult shown in Fig. 4, this security door further comprises a tapered end 30, in the present embodiment, take this tapered end 30 as cylinder lock, (Pin Tumbler Lock) describes for example, certainly, the present invention is not limited to cylinder lock, applicable to using on key operated various lockset.This tapered end 30 comprises lock core (Plug) 31, key hole of door lock 32 and multiple pellet 33, and described pellet 33 comprises tack pellet (Driver pins) and lower pellet (Key pins) etc.
This camera head 20 is installed in the key hole of door lock 32 of tapered end 30 of security door 2, for obtaining the scene image in key hole of door lock 32, and the scene image obtaining is stored in memory 23.Intelligent pick-proof system 24 detects in this scene image whether the object being inserted in key hole of door lock 32 is unknown object (as picklock), in the time detecting unknown object, opens the safety device 22 in this security door 2, by the latch of safety device 22.
In the present embodiment, this camera head 20 is a kind of degree of depth video camera (Depth-sensing Camera) that possesses depth of field recognition function, as time flight (Time of Flight, TOF) camera head.This camera head 20 is for absorbing the scene image in key hole of door lock 32, and obtains the depth of view information of subject in scene image.The depth of view information of described subject refers to the range information of the camera lens of subject each point and camera head 20.Because TOF camera head is when the photographic subjects thing, by the signal of the certain wavelength of transmitting, in the time that running into object, signal can reflex to the camera lens of TOF camera head, can calculate the range information between each point and TOF camera head lens on object according to signal transmitting and the time difference between reception, therefore described camera head 20 can obtain the range information between subject each point and the camera lens of camera head 20 in scene image.
The 3-dimensional image template of the key that described memory 23 mates for this tapered end 30 that stores camera head 20 and set up in advance.
In the present embodiment, described Intelligent pick-proof system 24 can be divided into one or more modules, described one or more module is stored in described memory 23 and is configured to and carried out by one or more processors (as the processor 25 in Fig. 1), to complete the present invention.For example, consult shown in Fig. 2, described Intelligent pick-proof system 24 is divided into three-dimensional template and sets up module 201, image acquiring module 202, object detecting module 203, comparing module 204 and control module 205.The alleged module of the present invention has been the program segment of a specific function, is more suitable for, in describing the implementation of software in processor 25, in the flow chart of Fig. 3, specifically describing about the function of each module than program.
Before starting Fig. 3 flow chart, three-dimensional template is set up module 201 and sets up according to the 3-dimensional image of the key mating with this tapered end 30 the 3-dimensional image template (hereinafter referred to as " key image template 40 ") of this key, store this key image template 40 to memory 23, be specifically described as follows.
Consult shown in Fig. 5, user inserts the key mating with this tapered end 30 in key hole of door lock 32.The 3 D stereoscopic image (i.e. the 3 D stereoscopic image of this key front end) of camera head 20 these keys of picked-up in key hole of door lock 32, using the 3 D stereoscopic image of this picked-up as key image template 40, and is stored to memory 23 by this key image template 40.
As shown in Figure 3, be the flow chart of the preferred embodiment of Intelligent pick-proof method of the present invention.
Step S10, image acquiring module 202 is every Preset Time (as 0.5 second), obtains the current scene image 42 that the camera head 20 of the key hole of door lock 32 interior installations of security door 2 absorbs.
Step S11, object detecting module 203 is detected object (as picklock) in the current scene image 42 obtaining.Particularly, if the distance of current scene image 42 and camera head 20 camera lenses is less than the distance of a scene image and camera head 20 camera lenses, 203 judgements of object detecting module detect object, have object to enter in key hole of door lock 32 (consulting shown in Fig. 6).In the present embodiment, the distance of scene image and camera head 20 camera lenses refers to: the characteristic point (as central point) in this scene image is to the distance of these camera head 20 camera lenses.
Step S12, object detecting module 203 judges whether to detect object in the current scene image 42 obtaining.If detect object in the current scene image 42 obtaining, perform step S13; If do not detect object in the current scene image 42 obtaining, return to step S10.
Step S13, current scene image 42 that comparing module 204 is obtained this and the key image template 40 setting in advance compare (consulting shown in Fig. 7).
Step S14, comparing module 204 judges whether current scene image 42 mates with key image template 40.In the present embodiment, comparing module 204 is calculated the similarity of current scene image 42 and key image template 40, if this similarity is greater than default ratio (as 90%), comparing module 204 judges that current scene image 42 mates with key image template 40, the object entering in key hole of door lock 32 is the key that this tapered end 30 mates, and flow process finishes.If this similarity is less than or equal to this default ratio, comparing module 204 judges that current scene image 42 does not mate with key image template 40, and the object entering in key hole of door lock 32 is unknown object (as picklock), execution step S15.
Step S15, control module 205, by the safety device 22 of actuating unit 21 unlatching burglar-proof doors 2 of security door 2, is locked the bolt of safety device 22 220.Consult shown in Fig. 8, state A represents non-alert status, and the bolt 220 of safety device 22 is not locked, and state B represents alert status, and the bolt 220 of safety device 22 is locked.
When key that this tapered end 30 mates insert key hole of door lock 32 interior after, control module 205 is removed the lock-out state of the bolt 220 of this safety device 22, the bolt of safety device 22 220 is return to initial position, allow the user can be with correct key turns tapered end 30, thereby open security door 2.
Finally it should be noted that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not depart from the spirit and scope of technical solution of the present invention.
