The method of identification Datamatrix Quick Response Code of the present invention is based on intelligent mobile phone platform, by mobile phone hardware---camera realizes the picked-up to Datamatrix image in 2 D code, identifies 2 D code information, and 2 D code information exports or display the most at last.The popularity of smart mobile phone is very high, and by smart mobile phone camera pickup image, by the accurate identification of image processing and analyzing to Datamatrix Quick Response Code, convenience is extremely strong.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention will be described in detail:
Fig. 1 is Datamatrix Quick Response Code basic block diagram.
Fig. 2 is Datamatrix Quick Response Code identification process figure.
In figure: 1 information data area, 2 positioning patterns.
Embodiment
Datamatrix Quick Response Code: Datamatrix original name Datacode, by international data company of the U.S. (InternationalDataMatrix is called for short IDMatrix) in invention in 1989.Datamatrix is a kind of matrix two-dimensional barcode, and the conception of its development wishes on less bar-code label stored in more data quantity.The minimum dimension of Datamatrix is minimum in current all bar codes, is especially specially adapted to the mark of finding, and is directly printed on entity.
As shown in Figure 1: the information data area 1 that each Datamatrix two-dimensional code symbol is made up of regularly arranged square module forms, the surrounding of information data area is surrounded by positioning pattern 2.The positioning pattern left side and following two adjacent sides are black solid line, form the positioning pattern of " L " property.The right and upper sid strip adjacent side are made up of the black and white module replaced, and concrete structure please refer to DaramatrixISO international standard.
That Fig. 2 shows is Datamatrix Quick Response Code identification process figure of the present invention.
By a method for smart mobile phone identification Datamatrix Quick Response Code, step is,
Step (1) calling mobile phone platform camera, auto-focusing: the present invention scans Datamatrix Quick Response Code by cell-phone camera head system, and adopts automatic focus adjustable, to make image clear displaying of energy under scan box.
Step (2) is analyzed the image information that scan box is shown, filters out non-Datamatrix image in 2 D code information; Datamatrix image in 2 D code information is analyzed, if possess the basic structure of Datamatrix Quick Response Code, then carries out next step;
Judge that whether figure is containing Datamatrix Quick Response Code; Software image signal processor identification frame hypograph information is carried out analysis and is detected, and filters out non-Datamatrix 2 D code information; Datamatrix Quick Response Code is detected and mainly basic structure analysis is carried out to it.Judge whether the Datamatrix basic structure existed as shown in Figure 1.
According to the basic structure of Datamatrix Quick Response Code, step (3) judges that whether Datamatrix image in 2 D code information is complete, complete, carry out next step;
Datamatrix integrality is differentiated: whether image-signal processor is by complete for the Datamatrix image in 2 D code obtained according to the comparison of accompanying drawing 1 basic structure.
Datamatrix image in 2 D code information extracts by step (4);
Extract image in 2 D code: this software image signal processor from identification block diagram picture after step (2) and step (3) judgement, Datamatrix image in 2 D code is extracted, preferably, the color image array extracted meets DaramatrixISO international standard, as accompanying drawing 1.
Step (5) carries out rotation process to the Datamatrix image in 2 D code information extracted, and makes image information meet the angle of Datamatrix bar code protocol requirement;
The anglec of rotation process of picture: image-signal processor carries out rotation process by the Datamatrix image in 2 D code of picked-up, makes image reach the angle meeting Datamatrix bar code protocol requirement in system.
Step (6), according to getting into principle, carries out black white binarization to the image information after rotating process;
Image in 2 D code binaryzation: image processor, according to getting into principle, carries out black white binarization operation to the image of picked-up.
Step (7) carries out Quick Response Code identification to binary image, the data message that reduction image information is corresponding, then this data message is formed packet and is exported or display by coded character by system interface;
Image in 2 D code identification: the built-in image-signal processor of these software systems carries out Quick Response Code identification to above-mentioned image, thus the data message that reduction Datamatrix Quick Response Code is corresponding, then form packet by this data message and directly export or show.
As Fig. 2: further, the identification of the image in 2 D code of Datamatrix Quick Response Code can be subdivided into following steps:
Transformation matrix: matrix change is carried out to the data that binaryzation obtains;
Rotate change: as needs then carry out rotation change to matrix;
Change of scale matrix: as needs then carry out change of scale to matrix;
Shear transformation matrix: as needs then carry out shear transformation to matrix;
The crooked conversion of top line: as needs then carry out the crooked conversion of top line to matrix;
Identification completes display result.
The display of recognition result: after signal processor completes the information processing to Datamatrix Quick Response Code, is presented on specific interface by system interface by coded character,
Coded character is mainly following several herein:
S81: numeric type coded character (numeral: 0 ~ 9);
S82: English words parent form coded character (English alphabet A ~ Z or a ~ z);
S83: the Chinese character character (character that GB18030-2000 appendix A double-byte characters table represents;
S84: mixed type character (comprise numeral, letter and Chinese character, three have concurrently or wherein both).
The present invention, mainly for the solution of existing deficiency and Datamatrix range of application about identifying Datamatrix contradiction more and more widely, is to the key breakthrough of Datamatrix Quick Response Code recognition technology convenience with popular style.
