Embodiment
The power supply circuit control method process flow diagram that Fig. 1 provides for the embodiment of the present invention.There is unsafe problem for contact gauge tap in the embodiment of the present invention, provide a kind of method controlling power circuit by non-contacting mode, concrete grammar step is as follows:
Step S101, collection target image;
The embodiment of the present invention provides a kind of power circuit control device, when user needs to control power circuit, some actions or posture can be done facing to this power circuit control device, this power circuit control device gathers target image from action or posture, the gesture, head oscillation pattern etc. of such as people.
Step S102, target image is carried out mating generate switching information with the switch image preset;
The target image collected mates with switch image by power circuit control device, switch image is the image preset in power circuit control device, this switch image specifically can comprise the pass image opening image and control power circuit pass controlling power circuit and open, and generate switching information according to matching result, the control information of namely opening or closing.
Step S103, foundation switching information are opened or powered-down circuit.
Power circuit control device is connected with power circuit, and carries out power circuit control according to the control information of opening or closing that switching information specifically represents, namely opens or powered-down circuit.
The embodiment of the present invention is by gathering the target image of user, target image is mated with switch image, and control power circuit according to the switching information that matching result generates, do not need finger touch switch just controllable power circuit, solve the unsafe problem of contact gauge tap.
On the basis of above-described embodiment, also comprise before step S101: receive and store user input switch image.
Switch image specifically can comprise the pass image opening image and control power circuit pass controlling power circuit and open.User is before this power circuit control device of use controls power circuit, switch image is first set, be specifically as follows user take an images of gestures by power circuit control device and this images of gestures is set to control power circuit open open image, take another Zhang Butong images of gestures and this images of gestures is set to control power circuit close pass image.
Receive and store user input switch image comprise:
Receive and confirm the switch image that user inputs;
Switch image is stored in register.
User have taken an images of gestures by power circuit control device, preset the image being set to and controlling power circuit and open, whether power circuit control device prompting user confirms, also follow-up prompts user can confirm limited number of times, prevent user from confirming by mistake, to make arranging of user authentic and valid, as power circuit control device follow-up prompts user arranges confirmation preset times to this, be specially 3 times, then after user confirms for 3 times, this images of gestures is set to control that power circuit leaves opens image, and is stored in register by this images of gestures; In like manner, the pass image of power circuit pass is controlled through same treatment.
In addition, the switch image in the embodiment of the present invention can also reset according to user's request.
The embodiment of the present invention is by pre-setting and storage switch image, the collection target image of user is mated with the switch image of storage, confirmed the switch image of user's input by limited number of time, prevent user from confirming, to make arranging of user authentic and valid by mistake.
The image matching method process flow diagram that Fig. 2 provides for another embodiment of the present invention.On the basis of above-described embodiment, the switch image in step S102 comprises the pass image opening image and control power circuit pass controlling power circuit and open, and is carried out mating comprising by target image with the switch image preset:
Judge target image and open image or close the similarity of image;
If similarity is greater than predetermined threshold value, then judges target image and open image or close images match success.
If target image does not mate with switch image, then Resurvey target image.
Alternatively, target image, to open image identical with closing the size of image.
As shown in Figure 2, by the target image collected i.e. this input picture with set open image or close image and mate, concrete steps are as follows:
Step S201, target image is set as A1, opening image or closing image setting of having set is A2;
Target image with to have set open image or closes image carry out matching judgment time, A2 only represents out image or pass image.
Step S202, acquisition A1 histogram AZ1, A2 histogram AZ2;
Histogram AZ1 represents the array be made up of redness corresponding to each pixel of A1, green, blueness, color space (Red, Green, Blue, Alpha are called for short RGBA).Histogram AZ2 and histogram AZ1 in like manner.Specifically how to belong to prior art by the corresponding histogram of Image Acquisition, do not repeat them here.
Step S203, acquisition AZ1 grey level histogram array AGZ1, AZ2 grey level histogram array AGZ2;
AZ1 grey level histogram array AGZ1 represent from the RGBA that each pixel of A1 is corresponding, only get redness, green or blue pixel value after the array that forms.AGZ2 and AGZ1 in like manner.Specifically from histogram, how to obtain corresponding grey level histogram array belongs to prior art, does not repeat them here.
Whether step S204, the length comparing array AGZ1 and array AGZ2 is equal, forwards step S205 to, forward step S206 to if equal if unequal;
Such as, if AGZ1 represent from the RGBA that each pixel of A1 is corresponding, get red pixel value after the array that forms, then the length of array AGZ1 represents that in all pixels that A1 is corresponding, red pixel value is not the number of 0.The length of array AGZ2 and the length of array AGZ1 are in like manner.
Step S205, judge that A1 and A2 does not mate;
Such as, if in all pixels corresponding to A1 red pixel value be not in number all pixels corresponding with A2 of 0 red pixel value be not 0 number not identical, then judge that A1 and A2 does not mate, and Resurvey user images is as target image.
The similarity of step S206, calculating A1 and A2;
If in all pixels that A1 is corresponding red pixel value be not in number all pixels corresponding with A2 of 0 red pixel value be not 0 number identical, then judge the similarity of A1 and A2 further, specifically judge that A1, A2 red pixel value is not have how many red pixel value equal in the pixel of 0.
Calculate the similarity of A1 and A2, by following C# language codes implement, the agz1 in code represents above-mentioned AGZ1, and the agz2 in code represents above-mentioned AGZ2:
Wherein, function f loatGetDuplationRate call function floatGetColorAbs, result/j represents the similarity returned.
Step S207, when judging that Similarity value is greater than preset ratio, know that A1 and A2 mates.
Such as, when A1, A2 red pixel value is not have the red pixel value of 80% equal in the pixel of 0, then judge that A1, A2 mate.
The embodiment of the present invention is by gathering the target image of user, target image is mated with switch image, and control power circuit according to the switching information that matching process generates, do not need finger touch switch just controllable power circuit, solve the unsafe problem of contact gauge tap, in addition, the antihygienic problem of contact gauge tap can also be solved.
