Problems solved by technology

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

Abstract

The invention discloses an information code identification method and system, belonging to the technical field of information code identification. the image of the information code; perform binarization processing on the image of the information code to obtain the image of the information code after binarization; traverse the image of the information code after the binarization, Convert the dots into a bit matrix; convert the bit matrix into a bit stream, and decode to obtain the product anti-counterfeiting information in the information code image. The invention can identify the product anti-counterfeiting information in the information code and the traceability information in the surrounding positioning code, and even if the combined coding pattern is partially covered and worn, the product anti-counterfeiting information can be identified.

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 and the convenience of transportation, the phenomenon of commodity smuggling is becoming more and more serious. At present, there are many ways to deal with anti-smuggling goods. There are many applications such as implementing product code system from the industrial and commercial administration department, printing two-dimensional code or barcode on reflective material to store some commodity information, etc. Two-dimensional code is a very A convenient means of information transmission, merchants can use the QR code to push their own Weibo, official account or product serial number, etc. However, it also has obvious defects in the use process: First, the coding method of the two-dimensional code or barcode is relat...
