Two-dimensional code compiling method

Abstract

The invention discloses a two-dimensional code compiling method. The two-dimensional code compiling method comprises the following steps of: on the basis of a self-adaptive code compiling extended black and white code compiling technology and a code compiling scheme applicable to different multimedia, introducing an interweaving technology into an error-correcting code compiling technology by using a data compression technology with an open structure during compression code compiling; and adopting an advanced morphologic image pre-processing technology based on multi-scale structural analysis. The two-dimensional code compiling method has the advantages that a two-dimensional code is superior to the conventional two-dimensional code standard in terms of information bearing capacity, robustness, safety, reliability and adaptability; and coding and decoding bottom-layer supporting software provides technical support for various types of application of the two-dimensional code to the field of the internet of things in an open interface mode, the market monopoly position of the conventional foreign two-dimensional code standard can be broken, the chaotic situation of the conventional domestic two-dimensional code application is changed, and a firm foundation is laid for the development of the internet-of-things industry.

Description

technical field [0001] The invention relates to a coding method of a two-dimensional code, belonging to the technical field of two-dimensional codes. Background technique [0002] QR codes quickly entered the market in 2012, and were familiar and used by users. However, problems followed one after another. Because of the high attention paid to QR codes, all walks of life have begun to find ways to combine their businesses with them. Of course, some lawbreakers have also begun to use QR codes to commit crimes. Activities, when a user clicks on a QR code, sometimes a link appears, and in many cases it is directly a virus link, so it has a very bad impact on the user experience and damages the user's interests. At present, the main problem of QR codes is that there are many types of QR codes, and different QR codes are suitable for different application fields, and there are relatively few application systems developed for QR codes; at the same time, the current QR codes The ...

Problems solved by technology

However, problems followed one after another. Because of the high attention paid to QR codes, all walks of life have begun to find ways to combine their businesses with them. Of course, some lawbreakers have also begun to use QR codes to commit crimes. Activities, when a user clicks on a QR code, sometimes a link appears, in many cases it is directly a virus link, so it has a very bad impact on the user experience, resulting in damage to the user's interests

At present, the main problem of QR codes is that there are many types of QR codes, and different QR codes are suitable for different application fields, and there are relatively few application systems developed for QR codes; at the same time, the current QR codes The standardization of the two-dimensional code is not perfect, and the two-dimensional code technology is still very immature. All the code systems are all foreign code systems, and there are great security risks and intellectual property risks; in addition, the current two-dimensional code identification equipment structure Complicated, expensive, costly, and inefficient

[0005] 1) Low information security and no security standards: the information contained in the two-dimensional code is related to the national economy and the people's livelihood, and the two-dimensional code (such as QR) widely used in China does not have independent intellectual property rights, and information security cannot be guaranteed. In-depth, prominent security risks, and the lack of corresponding encryption standards in the existing two-dimensional code standards

[0006] 2) There are many QR code standards, and each of them is fighting: due to the extremely wide application market of QR codes, the potential market size is huge. Therefore, there are many companies and institutions that design and develop QR codes. International and domestic QR code standards There are more than ten, which makes it difficult to develop two-dimensional code reading equipment, and the cost is high, which limits the promotion and application of two-dimensional codes

[0007] 3) The two-dimensional code has little information, and the code itself does not contain information: the current mainstream two-dimensional code (such as QR code) has obvious deficiencies. For example, the QR code uses binary code, which means less information; If the QR code is not read, the image itself contains almost no information, which limits its application expansion

There is no encoding method suitable for different media, which limits the application of QR codes

For example: the characteristics of digital media and paper media are very different, using a unified encoding method does not make full use of the characteristics of the media

[0009] 5) The reliability of code reading is low: the two-dimensional code improves the reliability of decoding by means of error correction codes, but when there are large damages and scratches, the information of the two-dimensional code cannot be read

Once the QR code cannot be read, there is no remedy

This cannot meet the application requirements that require extremely high information security and reliability.

[0010] 6) The efficiency of decoding and error correction algorithms is low: the RS decoding algorithms given in the existing two-dimensional code standards are all based on solving linear equations, which have high computational complexity and slow decoding speed
