Embodiment 1

[0072] figure 1 It is a schematic flowchart of a method for generating a two-dimensional code provided in the embodiment of this specification. From a program point of view, the subject of execution of the process can be a program or an application client installed on an application server.

[0073] Such as figure 1 As shown, the process may include the following steps:

[0074] Step 110: Obtain the two-dimensional code code of the two-dimensional code image to be generated.

[0075] The two-dimensional code code can represent the code used to generate the two-dimensional code image, for example, it can be a string of preset digits, such as a binary sequence, a ternary sequence, and the like. In this solution, taking the binary sequence as an example, the content data carried in the two-dimensional code can be converted into a series of two-dimensional code sequences after information conversion.

[0076] It should be noted that the two-dimensional code here may refer to a...

Embodiment 2

[0131] image 3 It is a schematic flowchart of a two-dimensional code decoding method provided by the embodiment of this specification. From a program point of view, the subject of execution of the process can be a program or an application client installed on an application server. The decoding process in Embodiment 2 corresponds to the encoding process in Embodiment 1.

[0132] Such as image 3 As shown, the process may include the following steps:

[0133] Step 310: Obtain the image information of the image of the two-dimensional code to be recognized.

[0134] It should be noted that the image information mentioned in this step can represent the information of the two-dimensional code itself that is not limited by the carrier of the two-dimensional code, for example: the information of the two-dimensional code drawn on the computer. For example: the size information of the two-dimensional code, the position information of each positioning point, the position informatio...

Abstract

The embodiment of the invention discloses a two-dimensional code generating and decoding method, device and equipment. The method comprises the following steps: acquiring a two-dimensional code of a two-dimensional code image to be generated, and performing fault-tolerant coding by adopting a coding algorithm with a preset fault-tolerant rate to obtain a two-dimensional code after fault-tolerant processing; determining a code element shape corresponding to each data information bit of the two-dimensional code code after the fault-tolerant processing in a generation area of the two-dimensional code image; according to a two-dimensional code preset arrangement rule, determining first position information corresponding to each data information bit of the two-dimensional code after fault-tolerant processing in the generation area; determining second position information of each positioning point location in the generation area; and generating a two-dimensional code image based on the first position information, the code element shape corresponding to each data information bit and the second position information of each positioning point position.

Description

technical field [0001] The present application relates to the field of Internet technology, and in particular to a two-dimensional code generation and decoding method, device and equipment. Background technique [0002] In recent years, the application of QR codes has become more and more widespread, especially in the fields of mobile payment and online social networking. Due to its large information capacity and fast identification, it has been rapidly popularized in people's daily life. Although QR codes have been popularized on a large scale, in traditional QR codes, behind each QR code may represent a file, a page, or an application. Due to its openness, it is easy to become a breeding ground for Trojan horse viruses. When users scan codes, they may give up scanning codes because they are worried that their mobile phones may be infected with viruses after scanning codes, and traditional QR codes cannot meet the brand promotion of small programs. need. [0003] Based o...
