Analysis and physical analysis.Wherein show that analysis is the analysis to the display capabilities and display effect of mobile phone screen；And physics point
Analysis is the analysis to the integraty of mobile phone screen under breath screen state.
First image can reflect the display capabilities and display effect of mobile phone screen, can be objectively and accurately by the first image
Get correlated results.What display capabilities and display effect were generally referred to is screen permeability, color saturation, color rendition degree
Deng display characteristic.What the parameter value of the display characteristic reflected is the degree of the page effect shown by one piece of screen.Example
Such as, there is an image A in the first image, be reference white in the corresponding pre-set colors of image A, and image A is shown out
Content do not reach the rank of reference white, there is slightly partially green phenomenon.So, its analysis result is：Shown by image A
Reference white be not accurate enough, occur in that the situation of colourity imbalance, the working mechanism of screen kinescope and image are looked after and guided
Function can not be merged well.
Step S32, is analyzed to the second image, to obtain breath screen analysis result.
Second image is shot in the case where mobile phone screen is in breath screen state, except that can analyze the complete of mobile phone screen
Whole degree, can also analyze the segmental defect of mobile phone screen and the integraty of screen.Under breath screen state captured by second image
Screen should be one piece of complete screen.By being the sample that can intuitively understand by the characteristic strengthening of the display content of second graph
Formula, and then analyze various irregular features therein, such as the defect in the physical attribute such as bad point and screen slight crack
Feature.
The bad point refers to that some screen pixels on screen panel completely or partially lose its effect, and causes to become forever
The bright spot of long property, dim spot or color dot.And screen slight crack refers to the screen fragmentation that screen is caused by the extruding of the external force such as drop impact.

Reason aspect is perfectly combined together.There is good Feature Extraction Technology in the data processing storehouse of OpenCV, can be to image
Realize accurately image recognition, data processing, feature extraction and detection and analysis.
The pattern feature very abundant included in first image, such as histogram feature, color characteristic, template characteristic, structure
Feature etc..The function of the present embodiment is exactly to pick out wherein useful information, and realizes Data Detection using these features.
In general, feature is generally divided into visual signature, pixels statisticses feature, image transform coefficients feature, image algebra
Feature etc..The method of feature extraction is summed up and is divided into two major classes：One kind is Knowledge based engineering characterizing method；Another is base
In algebraic characteristic or the characterizing method of statistical learning.Knowledge based engineering characterizing method is mainly the data message according to the first image
Algebraic logic and data difference each other contribute to the characteristic results of information classification to obtain；Based on algebraic method
Sign includes two kinds of template matching method and the method based on geometric properties.
Step S312, analyzes the characteristic results of all first images, to obtain display analysis result.

As a result.The image algorithm for being used can have different specific aims according to the difference of the image technique for being used.Assuming that this reality
It is OpenCV technologies to apply the image technique that example used, and after image characteristics extraction was carried out, characteristic results must be different
Signature analysis.The data matrix corresponding to each signature analysis is analyzed, because each data matrix corresponds to each pixel
The specific display capabilities of point and display effect, therefore mean the detection of pixel scale to the analysis of each characteristic results.It is false
If in the presence of a pixel A, its analysis result is inaccurate for reduction, corresponding to the Standard Colors in colour gamut, display capabilities occurs
Upper great data offset, causes not up to standard in display effect.And pass through countless pixel point feature knots on mobile phone screen
