Problems solved by technology
However, since the generation method of the one-dimensional code is easy to be cracked, its anti-counterfeiting effect is very poor
[0003] In order to solve the problem of poor anti-counterfeiting effect of the above-mentioned one-dimensional code, a new idea has emerged, which combines one-dimensional code with dot matrix graphics to form a new type of anti-counterfeiting mark
Yet for this kind of anti-counterfeiting label, there is no method for identifying it at present

Embodiment Construction
[0079] The invention provides a method capable of simultaneously recognizing one-dimensional codes and dot matrix graphics, comprising the following steps:
[0080] Scan the dot matrix pattern in the anti-counterfeiting mark, analyze the obtained dot matrix pattern image, and distinguish the authenticity of the dot matrix pattern;
[0081] Scan the one-dimensional code that constitutes the anti-counterfeiting mark, and analyze the obtained one-dimensional code image, so as to extract the analyzed dot matrix graphic ID corresponding to the one-dimensional code;
[0082] Comparing the analyzed dot matrix graphic ID corresponding to the one-dimensional code with the analyzed dot matrix graphic ID corresponding to the dot matrix graphic to determine whether the two match;
[0083] According to the above matching results, call the content information corresponding to the two dot matrix graphic IDs in the database;
[0084] Broadcast content information.
[0085] Such as figure 1...

The invention provides a method capable of identifying a one-dimensional code and a raster graphic at the same time. The method includes the following steps that the one-dimensional code is scanned, a one-dimensional code image is analyzed, and a raster graphic ID after the analysis is extracted; the raster graphic is scanned, a raster graphic image is analyzed, and a raster graphic ID after the analysis is extracted; the two raster graphic IDs are compared, and whether the two raster graphic IDs are matched or not can be judged; according to a matched result, content information corresponding to the two raster graphic IDs at the same time is called in a database; the content information is broadcasted. A device adopting the method comprises a shell, a trigger, a mainboard provided with a central processing chip, a one-dimensional code scanning part, a raster graphic scanning part, a comparison module, a calling module and a feedback module. According to the method and device for identifying the anti-counterfeiting mark composed of the one-dimensional code and the raster graphic, the anti-counterfeiting mark implanted into the surface of an article and composed of the one-dimensional code and the raster graphic can be scanned at the same time, after the two raster graphic IDs are compared, relevant content is fed back, and the defect that the anti-counterfeiting mark cannot be identified at present is overcome.
Description
technical field [0001] The invention relates to a recognition method, in particular to a method and device for recognizing an anti-counterfeiting mark composed of a one-dimensional code and a dot matrix pattern. Background technique [0002] One-dimensional codes (also known as one-dimensional barcodes) are widely used in commerce, postal services, library management, warehousing, industrial production process control, transportation and other fields. They have the advantages of fast input speed, high accuracy, low cost, and strong reliability. However, since the generation method of the one-dimensional code is easy to be cracked, its anti-counterfeiting effect is very poor. [0003] In order to solve the problem of poor anti-counterfeiting effect of the above-mentioned one-dimensional code, a new idea has emerged, which combines the one-dimensional code with dot matrix graphics to form a new type of anti-counterfeiting mark. However, there is currently no method for identi...
