Embodiment
Be the running environment figure of scanning two-dimension bar code of the present invention system as Fig. 1, scanning two-dimension bar code system 10 operates in a computing equipment, and as computing machine 2, this two-dimensional bar code scanning system 10 is used for the two-dimensional bar code of scanning product 1 to be measured.Product 1 to be measured can be electronic products such as smart phone, panel computer, personal digital assistant.
Computing machine 2 is equipped with image collecting device 12, and CPU 14, timer 16.Image collecting device 12 is used for gathering the two-dimensional bar code picture of product 1 to be scanned, and image collecting device 12 can be a camera in the present embodiment.CPU 14 is computing center and control centers of computing machine, is used for the operation of control native system.Timer 16 is equivalent to a clock, during the program operation, every time interval through a setting, timer 16 will trigger a timing event, therefore for according to time interval rule, the code that needs to carry out repeatedly can be carried out by timer triggering timing event, and timer 16 is exactly to trigger image collecting device 12 to carry out the collection of two-dimensional bar code picture in native system.
As shown in Figure 2, be the functional block diagram of scanning two-dimension bar code of the present invention system preferred embodiment.
This scanning two-dimension bar code system 10 comprises startup module 100, image collection module 102, decoder module 104, judge module 106, preservation module 108.
Start module 100, be used for a newly-built text, open image collecting device 12, activate timer 16, and set the time interval of timer 16, the time interval can be 1 second.Described text is used for storing the decoded information of two-dimensional bar code picture.
Image collection module 102 is used for when timer 16 triggers image collecting devices 12 and gathers product two-dimensional bar code picture to be scanned by certain time interval, obtains the two-dimensional bar code picture and is kept at the shear plate from this image collecting device 12;
Decoder module 104 carries out operations such as pixel enhancing, locking data zone, data decoding for calling the picture of decoding functions to shear plate.Can recognize that according to the coding and decoding principle of two-dimension code two-dimension code is actually square or the rectangle code element be made up of many lattices and forms, change color by lattice is come statistics, the lattice of black represents binary one, and the lattice of white represents binary zero.Decoder module 104 calls decoding functions the two-dimensional bar code picture in the shear plate is analyzed decoding, and function return value namely is the decoded information of this two-dimensional bar code; Decoder module 104 can convert the decoded information of two-dimensional bar code to character string type, and a newly-built string variable, gives this newly-built string variable with the decoded information assignment that converts the two-dimension code of character string type to.
Judge module 106, be used for judging whether to decode successfully, for example, judge by the value of judging decoder module 104 newly-built string variables whether decoding is successful, if the value of newly-built string variable is empty, decoding failure then, finish the once operation of timer, treat appointed interval after the time again running timer trigger image collecting device 12 and carry out the collection of two-dimensional bar code picture, this fixed time can be a second at interval, if the value non-NULL in the newly-built string variable illustrates and decodes successfully.
Preserving module 108, be used for when decoding successfully, is the text that the decoded information of two-dimensional bar code writes above-mentioned foundation with the data in the newly-built string variable.
As shown in Figure 3, be the process flow diagram of autoscan two-dimensional bar code method of the present invention preferred embodiment.
Step S200, a newly-built text starts the interface that module 100 is opened image collecting device 12 and operation image harvester 12, activates timer 16, and sets the time interval of timer 16, and the time interval can be 1 second.
Step S202, timer 16 is gathered the two-dimensional bar code picture of product to be measured automatically according to triggering image collecting device 12 interval time of aforementioned setting, and picture acquisition module 102 obtains this two-dimensional bar code picture that collects and is kept in the shear plate then;
Step S204, decoder module 104 call decoding functions and the picture in the shear plate are carried out operations such as pixel enhancing, locking data zone, data decoding.Can recognize that according to the coding and decoding principle of two-dimension code two-dimension code is actually square or the rectangle code element be made up of many lattices and forms, change color by lattice is come statistics, the lattice of black represents binary one, and the lattice of white represents binary zero.Decoder module 104 calls decoding functions the two-dimensional bar code picture in the shear plate is analyzed decoding, function return value namely is the decoded information of this two-dimensional bar code picture, decoder module 104 can convert the decoded information of two-dimensional bar code picture to character string type, and a newly-built string variable, give this newly-built string variable with the decoded information assignment that converts the two-dimension code of character string type to.
Step S206, judge module 106 judges whether to decode successfully, for example, judge by the value of the newly-built string variable of determining step S204 whether decoding is successful, if the value of newly-built string variable is empty, decoding failure then, finish the once operation of timer 16, return step S202 treat appointed interval after the time again running timer 16 trigger image collecting devices 12 and carry out the collection of two-dimensional bar code picture, this fixed time can be a second at interval, if the character value non-NULL in the string variable illustrates and decodes successfully.
Step S208, when decoding successfully, preserving module 108 is that the decoded information of two-dimensional bar code picture is kept in the described text with the data in the newly-built string variable, the closing image harvester 12 then.
In the above-mentioned flow process be the two-dimensional bar code picture that scans a product to be measured be that example describes, if being arranged, a lot of products to be measured wait for the scanning two-dimension bar code picture, so in step S208, after the decoded information with the two-dimensional bar code picture is kept in the described text, do not need to freeze timer and closing image harvester 12, but the once operation of end timer 16, and return step S202 treat appointed interval after the time again running timer 16 to trigger the two-dimensional bar code picture of image collecting device 12 scannings product 1 to be measured, repeated execution of steps S202 is to the two-dimensional bar code been scanned of step S208 up to all products to be measured, then, freeze timer then, closing image harvester 12.
Above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.
