Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Core of the present invention is, the detected portable terminal of the master control module controls of detection system is taken predefined external image, and the template data of preserving in the shooting results that gets access to and the template data module compared, and judge according to comparative result whether this portable terminal is qualified.Whole detection has improved detection efficiency fully by computer automatic execution, simultaneously, because object relatively is two groups of data in fact, makes whole comparison procedure more objective and accurate, and therefore, testing result can not influence by detected personnel's subjective factor.
The detection system structure of portable terminal of the present invention as shown in Figure 1.In native system, comprise two modules: main control module and template data module.
Wherein, the template data module is used to preserve template data, just as the data to be compared of template, as data such as size, angularity, colourities; Main control module is used to control detected portable terminal predefined external image is taken, and relatively from the shooting results of detected portable terminal with from the template data of described template data module, such as, data such as the size in data such as the size in the shooting results, angularity, colourity and the template, angularity, colourity are compared, if both differences are in presetting thresholding then the qualified signal of the detected portable terminal of output expression, otherwise the underproof signal of output this portable terminal of expression.
More than the detection system structure of portable terminal is illustrated, below the dynamic duty process of this system is simply introduced.
Main control module in the detection system is controlled detected portable terminal by the Data Control mouth of detected portable terminal predefined external image is taken, and obtain shooting results by this Data Control mouth, then, with this shooting results with compare from the template data of template data module in the system, if both differences are in presetting thresholding then the qualified signal of the detected portable terminal of output expression, otherwise the underproof signal of output this portable terminal of expression.
The method flow of a better embodiment portable terminal detection system of the present invention as shown in Figure 2.
In step 210, detected portable terminal is taken specific image.Specifically, when the detected portable terminal that camera is installed during at the ad-hoc location that is in when detecting, such as the camera of detected portable terminal is when being right against predefined external image, main control module in the detection system, is taken as the specific image of the various stripeds that can embody angularity, the various color lumps that embody colourity and so on predefined external image by the mobile terminal data control mouthful camera that this used for mobile terminal of control is self-contained.
Then, enter step 220, obtain shooting results.Specifically, the main control module in the detection system obtains the view data of having taken by the Data Control mouth of detected portable terminal, just in step 210, takes the shooting results that obtains behind the specific image.
Then, enter step 230, shooting results and template data are compared by main control module.Specifically, stored data to be compared in the template data module in system,, and this template data sent to main control module in the system as data such as size, angularity, colourities as template.The shooting results that main control module will obtain in step 220 and this template data compare.Because what detected portable terminal was captured is predefined external image, and, the shooting results that main control module gets access to by the Data Control mouth is one group of data in fact, therefore, this shooting results and template data can be carried out various comparisons, content relatively can comprise the combination in any of size of images, angularity and colourity or one of them.And, whether cross-color, distortion, phenomenon such as fuzzy can be arranged according to the image that the concrete data difference in the comparative result is judged shooting, that is to say, main control module can to shooting results be stored in template data in the template data module and compare after, according to the concrete data difference in the comparative result whether in allowed band, whether qualified, judge just whether the camera of this detected portable terminal is qualified if judging the captured image that goes out of the self-contained camera of detected used for mobile terminal.Such as, default thresholding in main control module, if the image of taking and template horizontal stroke, vertical number of pixels are all identical, then the value of respective pixel is subtracted each other, and the result after subtracting each other got variance, if this variance has surpassed predetermined thresholding, judge that then the captured image that goes out of this detected used for mobile terminal self-contained camera is defective.Certainly, can more multinomial respectively content relatively the time, can adopt different comparison algorithms to each content, finally obtain quantitative comparative result, therefore, can know not only whether the captured image of the camera of detected portable terminal is qualified, under underproof situation, can also further know the captured underproof concrete place of image of camera of detected portable terminal, for example, be to have cross-color, or anamorphose, phenomenon such as still image blurring.
Then, enter step 240, whether qualified main control module output comparative result just export detected portable terminal signal.Because in step 230, whether main control module has been judged the captured image of the self-contained camera of detected used for mobile terminal qualified, therefore, main control module just can and then know also whether the camera quality of detected portable terminal is qualified.If portable terminal is qualified by the image of self camera shooting, then main control module is exported the qualified signal of detected portable terminal; Equally, if the image that portable terminal is taken by self camera is defective, then main control module is exported the underproof signal of detected portable terminal.At above-mentioned case, if the difference of shooting results and template data is in presetting thresholding, then the qualified signal of the output described portable terminal of expression is represented the underproof signal of this portable terminal otherwise export.
In the present embodiment, take predefined external image by the detected portable terminal of the master control module controls in the detection system, and the shooting results that gets access to and the template data that is stored in the template data module compared, can more multinomial respectively content relatively the time, can adopt different comparison algorithms to each content, finally obtain quantitative comparative result, this makes that process relatively is more objective and accurate, and judges according to comparative result whether this detected portable terminal quality is qualified.Whole testing process can be automatically performed by detection system fully, improved detection efficiency, and in comparison procedure, relatively come down to two groups of data, therefore, take specific image with the camera by detected portable terminal and be presented at shooting results on the display screen of this portable terminal and carry out manual detection and compare, testing result can be different along with testing staff's difference, improved accuracy of detection greatly.
Though pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
