However, there are also obvious defects in its use: First, the encoding method of the two-dimensional code or barcode is relatively simple, and the decoding method is relatively mature, and the product information can be easily copied and forged
Second, if the information of the QR code or barcode is lost, such as if the picture is blocked, it will have a great impact on decoding, and even the information cannot be read, and the readability of the information is poor

Embodiment Construction
[0066] In order to further illustrate the features of the present invention, please refer to the following detailed description and accompanying drawings of the present invention. The accompanying drawings are for reference and description only, and are not intended to limit the protection scope of the present invention.
[0067] Such as figure 1 As shown, this embodiment discloses a method for identifying information codes, which is used to identify combined coded images generated in another invention application filed by the applicant entitled "A Method for Generating Information Codes", and restore the The product anti-counterfeiting information in the information code specifically includes the following steps S101 to S104:
[0068] S101. Acquire a picture of the combined coded image, and identify the image of the information code;
[0069] It should be noted that, when identifying the combined coded image, the part of the information code is first identified from the com...

The invention discloses an information code recognition method and system, belongs to the technical field of information code recognition, and comprises the steps: recognizing a combined coded image obtained through the combination of an information code and a positioning code, obtaining a picture of the combined coded image, and recognizing the image of the information code; performing binarization processing on the image of the information code to obtain a binarized information code image; traversing the binarized information code image, and converting all points in the binarized informationcode image into a bit matrix according to the binarized information code image; and converting the bit matrix into a bit stream, and decoding to obtain the product anti-counterfeiting information inthe information code image. According to the method, the product anti-counterfeiting information in the information code and the traceability information in the surrounding positioning code can be identified, and the product anti-counterfeiting information in the information code can also be identified even if the combined coding pattern part is shielded and worn.
Description
technical field [0001] The invention relates to the technical field of information code identification, in particular to an information code identification method and system. Background technique [0002] With the development and popularization of the Internet, as well as the convenience of transportation, the phenomenon of goods fleeing is becoming more and more serious. At present, there are many ways to deal with anti-smuggling goods. There are many applications such as the implementation of product code system by the industrial and commercial management department, and the printing of two-dimensional codes or barcodes on reflective materials to store some commodity information. Two-dimensional codes are a very A convenient means of information transmission, merchants can use QR codes to push their own Weibo, official account or product serial number, etc. But it also has obvious defects in the use process: first, the encoding method of the two-dimensional code or barcod...
