For the RGB original image of image collecting device shooting, due to spectral response functions difference, obtained RGB figure may
There can be result error, and then influence the judgement of subsequent B/G value.For this purpose, it is corrected after obtaining RGB original image, with
Obtain RGB correction chart.
Specifically, chromatic aberration correction is carried out to RGB original image using RGB correction coefficient, RGB correction coefficient is by acquiring RGB original image
The spectral response curve of image collecting device be compared acquisition with the color tristimulus values curve of standard.Specific method is such as
Under:
1, the spectral response curve of image collecting device is obtained
1) pass through standard sources (such as halogen tungsten lamp light source) stabilized illumination.
2) light for issuing standard sources adjusts prism angle in monochromator by rotation process and realizes list by monochromator
One specific wavelength light projects.
3) it is acquired by the light data that image collecting device projects monochromator, obtains the RGB figure of the wavelength
Picture.
4) it records each figure layer brightness value of the image R, G, B and stores.

Spectral response curve is compared with the color tristimulus values curve of 1931 standard of CIE of standard, to obtain turning for correction color
Change coefficient.Specific step is as follows:
Convert the mode of image RGB to the transformation rule of XYZ mode under CIE standard are as follows:
Wherein E (λ) indicates the function of spectral power distribution of light source；It is each for color camera R, G, B
The spectral responsivity of wave band；
K is normalization coefficient；Respectively CIE1931 standard colorimetric system color matching functions；
Therefore the color correction COEFFICIENT K of each wave band of R, G, Br、Kg、KbFor
Image collecting device just can be obtained after simultaneous (1), (2) formula, CIE is corresponded to by calibrated rgb light spectrogram
Substandard XYZ type.It can realize that R, G, B spectrogram and the substandard XYZ of CIE compare by the step, to identify
Whether the camera is calibrated and meets the requirements, i.e., setting correction coefficient is 1 at this time；It needs to pass through public affairs if the two error is too big
The color of the color camera is corrected by the correction coefficient of formula (3).
RGB original image is converted to the RGB image for containing only blue-green flame, specifically includes the following steps:
1, the RGB original image is converted into HSV figure.
2, the H layer in the HSV figure is extracted, H layers of filter mesh layer are constructed with bluish-green colour range value.Due to H, S, V tri- in HSV figure
Layer is mutually indepedent, therefore can directly carry out H layers of extraction, and H layers of filter mesh layer are constructed using bluish-green colour range value as selected threshold,
Bluish-green colour range value for example may be set to 0.5-0.7.
3, with the H layers of filter mesh layer respectively in the RGB original image R layer, G layers, B layers respectively dot products, thus obtained R
Layer, G layers, B layers be the figure layer for containing only blue-green flame.
4, to after dot product R layer, G layers, B layers synthesized to obtain the RGB for containing only blue-green flame figure.
The B/G value of the RGB image after S3, calculating are converted；
Since image background and noise may interfere the precision that B/G value calculates in RGB image, for this purpose, calculating
RGB image can be filtered before B/G value and denoising.
The calculation method of B/G value is that for the ratio of B figure layer and G figure layer as B/G value, B/G value can be figure in extraction image
The B/G value in B figure layer and G figure layer as at certain point, is also possible to the average B/G value of B figure layer and G figure layer in whole image,
Such as can using in image in B figure layer in the summation of all the points and G figure layer the ratio of the summation of all the points as the B/G value that is averaged.
S4, the B/G value is inputted into flame equivalence ratio judgment models, calculates the equivalent proportion of the flame colorIt is described
Flame equivalence ratio judgment models are according to the known equivalent proportion under fuel combustion state flameAnd its B/G of corresponding flame color
Value is established.
According to the known equivalent proportion under fuel combustion state flameAnd its described in the B/G value foundation of corresponding flame color
Flame equivalence ratio judgment models, comprising the following steps:
1, the different equivalent proportions of fuel combustion state flame are collectedAnd its B/G value of corresponding flame color.Specifically,
The ratio of fuel and air is controlled to adjust, using gas flowmeter to obtain specific equivalent proportionUnder stabilization flame, while benefit
The RGB original image of flame color is shot with image collecting device, and the specific equivalent proportion is calculated according to preceding methodUnder the conditions of
B/G value.The step is repeated, the B/G value of the flame image under different equivalent proportions is obtained.For example, by adjusting fuel and air
Ratio is divided into 0.05, and obtain each specified point pair in the equivalence ratio range so that flame equivalence ratio variation is 0.85~1.2
The B/G value answered.
2, using B/G value as input sample feature, with corresponding equivalent proportionTo export sample label, built by data fitting
Found the flame equivalence ratio judgment models.
It specifically, is output sample with corresponding equivalent proportion using the B/G characteristic value for acquiring and extracting as input sample feature
Label establishes flame image B/G characteristic value and the y (φ) of corresponding flame equivalence ratio φ=f (B/G) model by data fitting.
The B/G value is inputted into flame equivalence ratio judgment models, calculates the equivalent proportion of the flame colorSpecifically,
B/G value can be the specific set point in image, or the B/G value all put, and be also possible to all the points in image, or setting
The average B/G value put in range, at this point, equivalent proportionIt is corresponding specific set point, or the equivalent proportion all putOr
In image all the points or setting range in put average equivalent ratioIn the present embodiment, resulting equivalent proportion is calculated
For the average equivalent ratio put in all the points in image or setting rangeWherein setting range for according to need it is to be understood that figure
A certain range as in, can there is operator to delimit in advance, such as can be the square block of certain area, circle etc..
S5, by the equivalent proportionCompared with the equivalent proportion α of setting, if the equivalent proportionNot equal to the equivalent proportion α,
Or be not located within the scope of the equivalent proportion α, then fuel and air supply amount ratio are adjusted, the equivalent proportion is madeEqual to equivalent
Than α, or it is located within the scope of the equivalent proportion α.
In Actual combustion control, in order to achieve effective control, so that fuel and air supply amount ratio are suitable for.Specifically
Ground, the equivalent proportion that will be calculatedIt is compared with the equivalent proportion α of setting, if equivalent proportionEqual to the equivalent proportion α, or
Person is located within the scope of the equivalent proportion α, then keeps existing fuel and air supply amount constant rate.If the equivalent proportion
It is located within the scope of the equivalent proportion α not equal to the equivalent proportion α, or not, then adjusts fuel and air supply amount ratio, such as
The valve opening for controlling fuel channel and air pipeline, makes the equivalent proportionEqual to equivalent proportion α, or it is located at the equivalent proportion
Within the scope of α.Preferably, the equivalent proportion α set is a value range.
For example, fuel duty can be kept constant, fuel equivalence ratio, Huo Zheke are adjusted by adjusting amount of supplied air
