Wherein, rgb color pattern (be also translated as " RGB ", fewer with) is a kind of color standard of industrial quarters, is
By to red (Red), green (Green), the change of blue (Blue) three Color Channels and their superpositions each other come
To miscellaneous color, RGB is the color for representing three passages of red, green, blue, and this standard almost includes the mankind and regarded
The all colours that power can be perceived are current with one of most wide color system.Rgb color pattern is figure using RGB models
The intensity level that the RGB component of each pixel is distributed in the range of one 0 to 255 as in.For example：Pure red R values are that 255, G values are
0, B value is 0；Tri- values of R, G, B of grey are equal (except 0 and 255)；R, G, B of white are 255；R, G, B of black be
0.RGB image is only using three kinds of colors, so that it may so that they are mixed according to different ratios, 16777216 kinds are reappeared on screen
Color.Under RGB patterns, every kind of RGB compositions all can be used from 0 (black) to the value of 255 (whites).For example, shiny red uses R

When, result is pure white；When the value is 0, result is ater.
Specifically as shown in Figure 1 to Figure 3, a kind of electronic certificate identification triggering method that embodiments herein is provided, can be with
Including：
Step 1：To certificate rest area continuous collecting video image, and all single-frame images in the video image are equal
It is converted into the initial picture of rgb color pattern；
The single frames picture is converted into the initial picture of rgb color pattern, made each in the initial picture
Individual pixel all has red component, green component and blue component, in order to the red component beneficial to pixel, green component
And blue component, carry out the calculating of next step.The S301 in S201 and Fig. 3 in specific S101, Fig. 2 referred in Fig. 1.
Step 2：Calculate the average gray value and/or average color component of the difference predeterminable area of the initial picture；
The average gray value of the difference predeterminable area of the initial picture and average color component, which can be used as, judges institute
State the parameter that certificate whether is placed in certificate rest area.
In a specific embodiment as shown in Figure 1, the average ash of the difference predeterminable area of the initial picture is selected
Angle value is used as the parameter for judging whether to place certificate in the certificate rest area, as S102：Calculate the difference of the initial picture
It is worth the average gray value of predeterminable area.
Wherein, the average gray value of the difference predeterminable area refers to the ash of all pixels point in the difference predeterminable area
The average value of angle value.In step S101, we have been obtained for the red point of each pixel in the initial picture
Amount, green component and blue component.The gray value for calculating pixel by the color component of pixel has a variety of conversion formulas,
In actual use, most suitable formula can be chosen according to the Target Photo and identifying purpose of image recognition.
Particularly, step S102 can include：
S1021：By red component, green component and the blue component of each pixel in the difference predeterminable area,
Calculate the gray value of each pixel in the difference predeterminable area；
By taking any pixel point in the difference predeterminable area as an example, each pixel can be passed through by below equation
Red component, green component and the blue component of point, calculate the gray value of the pixel：
Grey=0.299*R+0.587*G+0.114*B
In addition, in order to avoid the floating-point operation of low speed, it would however also be possible to employ integer arithmetic, such as by scaling 1000 times come real
Existing integer arithmetic algorithm, i.e., calculate Grey value by below equation：
Grey=(299*R+587*G+114*B)/1000
Wherein, Grey represents the gray value of the pixel, and R represents the red component of the pixel, and G represents the pixel
Green component, B represents the blue component of the pixel.
S1022：The average value of the gray value of all pixels point in the difference predeterminable area is calculated, the difference preset areas is used as
The average gray value in domain.
In a specific embodiment as shown in Figure 2, the average face of the difference predeterminable area of the initial picture is selected
Colouring component is used as the parameter for judging whether to place certificate in the certificate rest area, as S202：Calculate the initial picture
The average color component of difference predeterminable area.
It is well known that color component includes red component, green component and blue component.With the average color component
During as judging whether to place the parameter of certificate in the certificate rest area, red component, green component and blueness can be chosen
One of which, two of which in component or three kinds are all selected, and this just includes six kinds of situations.According to selected color point
Amount, the average color component of the difference predeterminable area includes average red component and/or average green component and/or average indigo plant
Colouring component；Accordingly, the average color component of the difference predeterminable area of the initial picture is calculated, including：
It is the flat of the difference predeterminable area to calculate the average value of the red component of all pixels point in the difference predeterminable area
Equal red component, and/or
It is the flat of the difference predeterminable area to calculate the average value of the green component of all pixels point in the difference predeterminable area
Equal green component, and/or
It is the flat of the difference predeterminable area to calculate the average value of the blue component of all pixels point in the difference predeterminable area
Equal blue component.
In a specific embodiment as shown in Figure 3, the average ash of the difference predeterminable area of the initial picture is selected
Angle value and average color component are as the parameter for judging whether to place certificate in the certificate rest area, as S302：Calculate
The average gray value and average color component of the difference predeterminable area of the initial picture.
Such a situation be exactly using the average gray value in first two situation and average color component as parameter, therefore,
Calculating in this case, both needs to complete the calculating of average gray value, it is also desirable to complete the calculating of average color component.By
Include six kinds of situations in the selection of the average color component, therefore, such a situation correspondingly also includes six kinds of situations.
Step 3：Accordingly, initial picture described in former frame difference predeterminable area average gray value and a later frame
When the absolute value of difference between the average gray value of the difference predeterminable area of the initial picture is more than gray value difference threshold,
And/or initial picture described in former frame difference predeterminable area average color component and initial picture described in a later frame difference
When the absolute value for being worth the difference between the average color component of predeterminable area is more than color component difference threshold, output triggering letter
Number.
S103：It is corresponding with the first situation in S102, if as shown in figure 1, selecting the difference of the initial picture pre-
If the average gray value in region is as the parameter for judging whether to place certificate in the certificate rest area, i.e., described in former frame just
The average gray of the difference predeterminable area of initial picture described in the average gray value and a later frame of the difference predeterminable area of beginning picture
When the absolute value of difference between value is more than gray value difference threshold, it is believed that exist in the difference predeterminable area of the initial picture
" certificate feature ", that is to say, that there is certificate in the certificate rest area, now, exports trigger signal.
In order to further improve the precision of output trigger signal, at least one gray scale is additionally provided with the initial picture
Be worth predeterminable area, and initial picture described in former frame difference predeterminable area average gray value and a later frame described in it is initial
The absolute value of difference between the average gray value of the difference predeterminable area of picture is more than gray value difference threshold and a later frame institute
When the average gray value for stating at least one gray value predeterminable area of initial picture is more than gray value threshold value, trigger signal is exported.
Particularly, include a difference predeterminable area in the initial picture and multiple gray values are default
Region；The gray value threshold value includes multiple secondary gray value threshold values；In the difference predeterminable area of initial picture described in former frame
Average gray value and a later frame described in initial picture difference predeterminable area average gray value between difference absolute value
More than the average gray value of each gray value predeterminable area of initial picture described in gray value difference threshold and a later frame
When being all higher than the corresponding secondary gray value threshold value, trigger signal is exported.
S203：It is corresponding with second of situation in S102, as shown in Fig. 2 the difference that have selected the initial picture is pre-
If the average color component in region is as the parameter for judging whether to place certificate in the certificate rest area, i.e., described in former frame
The average color component of the difference predeterminable area of initial picture is averaged with the difference predeterminable area of initial picture described in a later frame
When the absolute value of difference between color component is more than color component difference threshold, it is believed that the difference preset areas of the initial picture
There is " certificate feature " in domain, that is to say, that there is certificate in the certificate rest area, now, export trigger signal.
From the foregoing it will be appreciated that according to selected color component, being divided into six kinds of situations, the average face of the difference predeterminable area
Colouring component includes average red component and/or average green component and/or average blue component；So, accordingly, the face
Colouring component difference threshold includes red component difference threshold and/or green component difference threshold and/or blue component difference threshold.
Therefore, in this step, the condition of output trigger signal also accordingly includes following several situations：
The difference of the average red component of the difference predeterminable area of the former frame picture and a later frame picture is preset
When difference between the average red component in region is more than the red component difference threshold, and/or
The difference of the average green component of the difference predeterminable area of the former frame picture and a later frame picture is preset
When difference between the average green component in region is more than the green component difference threshold, and/or
The difference of the average blue component of the difference predeterminable area of the former frame picture and a later frame picture is preset
When difference between the average blue component in region is more than the blue component difference threshold.
So that the average color component of the difference predeterminable area includes red component as an example, touched to further improve output
The precision of signalling, sets at least one red component predeterminable area in the initial picture, and in former frame picture
Between the average red component of the difference predeterminable area of the average red component of difference predeterminable area and a later frame picture
Difference is more than at least one red component predeterminable area of initial picture described in the red component difference threshold and a later frame
When average red component is more than red component threshold value, trigger signal is exported.
Particularly, include a difference predeterminable area in the initial picture and multiple red components are pre-
If region；The red component threshold value includes multiple secondary red component threshold values；In the difference predeterminable area of former frame picture
Difference between the average red component of the difference predeterminable area of average red component and a later frame picture is more than described red
The average red component of each red component predeterminable area of initial picture described in colouring component difference threshold and a later frame
When being all higher than the corresponding secondary red component threshold value, trigger signal is exported.
Again so that the average color component of the difference predeterminable area includes green component as an example, in order to further improve output
The precision of trigger signal, sets at least one green component predeterminable area in the initial picture, and in former frame picture
Difference predeterminable area average green component and a later frame picture difference predeterminable area average green component between
Difference be more than at least one green component predeterminable area of initial picture described in the green component difference threshold and a later frame
Average green component be more than green component threshold value when, export trigger signal.
Particularly, include a difference predeterminable area in the initial picture and multiple green components are pre-
If region；The green component threshold value includes multiple secondary green component threshold values；In the difference predeterminable area of former frame picture
Difference between the average green component of the difference predeterminable area of average green component and a later frame picture is more than described green
The average green component of each green component predeterminable area of initial picture described in colouring component difference threshold and a later frame
When being all higher than the corresponding secondary green component threshold value, trigger signal is exported.
Then so that the average color component of the difference predeterminable area includes blue component as an example, in order to further improve defeated
Go out the precision of trigger signal, at least one blue component predeterminable area is set in the initial picture, and in former frame figure
The average blue component of the difference predeterminable area of the average blue component of the difference predeterminable area of piece and a later frame picture it
Between difference be more than at least one blue component preset areas of initial picture described in the blue component difference threshold and a later frame
When the average blue component in domain is more than blue component threshold value, trigger signal is exported.
Particularly, include a difference predeterminable area in the initial picture and multiple blue components are pre-
If region；The blue component threshold value includes multiple secondary blue component threshold values；In the difference predeterminable area of former frame picture
Difference between the average blue component of the difference predeterminable area of average blue component and a later frame picture is more than the indigo plant
The average blue component of each blue component predeterminable area of initial picture described in colouring component difference threshold and a later frame
When being all higher than the corresponding secondary blue component threshold value, trigger signal is exported.
When the average color component of the difference predeterminable area includes its in red component, green component and blue component
In two kinds or three kinds all include when, by that analogy, repeat no more.
S303：It is corresponding with the third situation in S102, as shown in figure 3, the difference that have selected the initial picture is pre-
If the average gray value in region and average color component are as the parameter for judging whether to place certificate in the certificate rest area,
So, initial picture described in former frame difference predeterminable area average gray value and a later frame described in initial picture difference
The absolute value of difference between the average gray value of predeterminable area is more than initial picture described in gray value difference threshold and former frame
Difference predeterminable area average color component and initial picture described in a later frame difference predeterminable area average color component
Between difference absolute value be more than color component difference threshold when, can just export trigger signal.Equally, export in such cases
The standard of trigger signal, it is different according to the average color component of selection, also including six kinds of situations.
