Imaging data carry out graphical analysis, and compare with the video imaging effect before changing imaging pattern, if imaging effect
Fruit improves, then preserve current warm and humid degrees of data and lens parameters, if imaging effect is deteriorated, adjustment member parameter continues to compare
It is right, if three times are not all obviously improved effect, then recover original parameter, and record the environment factor, warehousing.Staff's meeting
The warm and humid degrees of data of similar special weather is periodically read, in case later data is analyzed.
The dry and wet degree of air is called " humidity ", commonly uses absolute humidity, relative humidity, compares humidity, mixing ratio, saturation deficit
And the physical quantity such as dew point is represented, represented using relative humidity in the present embodiment.I.e. Temperature Humidity Sensor gathers surrounding ring
The relative humidity in border, and the relative humidity of collection is transmitted to master control borad.When relative humidity is in 30%-80%, master control borad is obtained
Imaging pattern 1, imaging pattern 1 is Plateau histogram pattern, and movement calculates the gray value of whole screen, image model is adjusted by algorithm,
Contrast and brightness user can be adjusted manually, and to meet the vision needs of user, it is warm and humid that the pattern mainly acts on environment
Degree is more moderate, and the difference of each scenery is not it is obvious that in the case of grey value profile relative distribution.
When relative humidity is less than 30%, master control borad obtains imaging pattern 2, and imaging pattern 2 is contrast mode of priority, should
Contrast level parameter value has movement to be automatically adjusted to most suitable parameter value under pattern, and user can manually adjust brightness value, to meet
The vision of user needs, and the pattern mainly acts on that environment is relatively dry, and bulk temperature is higher, each scenery gray value all phase
In the case that contrast is larger.
When relative humidity is higher than 80%, master control borad obtains imaging pattern 3, and imaging pattern 3 is lightness preference pattern, the mould
Brightness parameter value is automatically adjusted to most suitable parameter value by movement under formula, and user can manually adjust contrast value, makes the scenery be in
Now compare clearly profile, the pattern is primarily adapted for use in rainy weather.
Step 4 gathers the gray scale of each pixel specifically, current frame image is converted into gray-value image by master control borad
Value, the gray value to neighbor pixel is compared, and draws present image intensity profile curve, drawing image profile, and change
Image outline between parameter is compared.If effect is obviously improved, then parameter current is preserved, if effect is deteriorated, continued
Adjustment member parameter, parameter includes definition, brightness and contrast.In the case that environment factor determines, the selection of thermal imagery camera lens
Different mode, definition is presented positive polarity booster action to imaging effect, but when definition is excessive, positive polarity effect can subtract
It is weak, but in the case of parameter value change is less, to image enhancement DeGrain, the adjustment of definition is controlled to adjust by master control borad
It is whole.Improve display brightness and scene outline so that the image quality for showing is more fine and smooth soft, brightness, the regulation of contrast can
Realized with manually adjusting, such as in pattern 1, brightness and contrast is adjusted manually, in pattern 2, adjusted manually bright
Degree, during pattern 3, can manually adjust contrast to obtain preferable imaging effect.If regulation is not all obviously improved for three times
Effect, then recover original parameter, and master control borad records the ambient parameter, and stock, and staff can periodically read similar special day
The humiture parameter of gas, in case later data is analyzed.
Under every kind of imaging pattern, fixed mode selection reduces environmental change amplitude as far as possible, and remaining parameter is surveyed by turns
Examination, finds definition, brightness, contrast, to imaging effect obvious effect, and pseudo- color and gamma value, to imaging effect shadow
Ring little,
Definition is demarcated, and in the case that environment factor determines, thermal imagery camera lens selects different mode, and definition is in imaging effect
Existing positive polarity booster action.But when definition is excessive, positive polarity effect can weaken；
Brightness and contrast, improves display brightness and scene outline so that the image quality for showing is more fine and smooth soft.Determine ring
In the case of the factor of border, brightness and contrast is coordinated to adjust, under observation different mode, brightness, contrast variation tendency, to drawing
The improvement trend of matter, statistic curve is made by experimental data.
It is of the present invention that the method for thermal imaging parameter is automatically adjusted in manpower adjustment and complex mathematical fortune based on environment factor
Compromise treatment is done between calculation, the tedious steps that manpower adjusts parameters in person have both been reduced, mathematical computations has been reduced again and is answered
The miscellaneous program operating load for bringing, it is ensured that gathering image has preferable visual quality, realizes thermal imaging movement in difference
Under the different weather environment factor of place, optimal image effect is all presented, makes parameter regulation more convenient first, save
Manpower, and parameter is more pressed close to, it is adapted to the working environment of machine, better image effect is presented.
Described above is only general principle of the invention and preferred embodiment, and those skilled in the art do according to the present invention
The improvement and replacement for going out, belong to protection scope of the present invention.
