Embodiment
The present invention provides a kind of character recognition tool and method thereof that is used for mobile terminal automation testing here, does not have a kind of problem that can realize simply and be used for the character recognition tool of mobile terminal automation testing in the prior art to solve.Below embodiment is described in detail, but not as a limitation of the invention.
The described character recognition tool of the embodiment of the invention is made up of 3 modules, comprising: character recognition technology (OCR) engine modules, OCR DLL (dynamic link library), image processing module, wherein,
The OCR engine modules is used for the image Chinese words after the image processing module processing is discerned; Wherein the OCR engine provides the function of ground literal identification, itself has very hi-tech, the OCR engine that we can select Microsoft to provide, and it is a disclosed DLL (dynamic link library).
Image processing module is used to be provided with the Flame Image Process parameter, and the picture that needs is carried out literal identification is handled according to the Flame Image Process parameter that is provided with; Image processing module can remedy the OCR of Microsoft engine identification colour picture effect defect of bad.Consider the single characteristics of the regular color of picture of mobile telephone Chinese words, we can the set handling parameter become simple artwork master to picture in image processing module, improved OCR literal discrimination, also other parameter can be set, as long as satisfy the identification demand.Here the Flame Image Process parameter of She Zhiing also can be the parameter of acquiescence, also can be the parameter of obtaining by behind the character recognition tool test recognition effect.
The OCR DLL (dynamic link library) is used to utilize the image Chinese words after the OCR engine modules is handled image processing module to discern the literal in the output image, and the Flame Image Process parameter of pointing out the user whether to preserve Set For Current.This DLL (dynamic link library) can be exported the literal in the coloured image, and the color of literal and the literal positional information in picture satisfies the demand of automatic test.
Be described in further detail in the concrete enforcement to character recognition method technical scheme of the present invention below, as shown in Figure 1, the technical program may further comprise the steps:
Step 101: input handset screen shots or other pictures (being the picture that selection need be carried out literal identification here).
Step 102: change the Flame Image Process parameter, different sampling types and sampling ratio can be set amplify downscaled images, (parameter in the image processing module can constantly expand according to actual needs here) such as different foreground and background colour filtering noises is set; And the picture that needs is carried out literal identification is handled according to the Flame Image Process parameter that is provided with;
Step 103: the Flame Image Process parameter of input is in the OCR DLL (dynamic link library), and character recognition effect checked in the literal in the output image.
Step 104: and point out the user, if satisfied, can preserve the current images processing parameter in document to recognition effect.
As shown in Figure 2, the concrete steps that are applied in the mobile phone automatized testing process of the concrete described character recognition method of the embodiment of the invention are as follows:
Step 201: during the operation automatic test script, the checkpoint (input expected effect value) of execution result is set.
Step 202: screen shots or other pictures of intercepting mobile phone.
Step 203: input handset picture and Flame Image Process parameter arrive in the OCR DLL (dynamic link library), the output character recognition result.
Step 204: the result of output and expected result comparison, verification operation is correctness as a result.
Step 205: image authentication correctly continues automatic test, and the image authentication mistake withdraws from testing procedure, and print error message.
Compared with prior art, simplification character recognition tool and method thereof that the present invention provides by described embodiment, the OCR engine that provides based on Microsoft, be aided with simple image pretreatment operation, substantially satisfied the required required literal discrimination of image authentication operation of mobile terminal automation testing, and realized simple.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
