Problems solved by technology
[0006] Aiming at the problems existing in the prior art that it is inconvenient to use in special scenes and has an abrupt appearance, it often needs to be placed in a separate eye-catching area, has poor concealment, and cannot be integrated with the background. The present invention proposes a bar-shaped The purpose of the method for generating and decoding a spliced two-dimensional code is to generate a two-dimensional code that can be spliced arbitrarily through this method. Since the boundary of the code is not fixed, it can be spliced according to specific application scenarios

Embodiment 1
[0037] Such as figure 1 , figure 2 and image 3 As shown, the present invention provides a method for generating bar-shaped spliced two-dimensional codes, including:
[0038] S1: First obtain such as figure 1 For the image outline of the logo image shown, the limited area of the image outline is used as the data area of the bar splicing two-dimensional code;
[0039] S2: Construct a coordinate system, and then generate several code blocks in the data area based on the coordinate system; the code blocks include data blocks and specific blocks, the data blocks are used to store data information, and the specific blocks are used to find standards when decoding Coordinate System. Adjacent rows of code blocks are staggered by a certain position and angle, and the Y direction can be quickly confirmed after finding the X direction during decoding.
[0040] S3: the data information is stored by setting bar lines in the data area; in S3 of the present invention, bar lines o...

The invention discloses a method for generating and decoding a bar-shaped spliced two-dimensional code, belongs to the technical field of two-dimensional codes, and aims to solve the problems that in the prior art, the bar-shaped spliced two-dimensional code is inconvenient to use in a special scene, has the defects of abrupt appearance, often needs to be placed in an independent striking area, is poor in hiding performance and cannot be fused with a background. The method comprises the following steps: firstly, acquiring an image contour, and taking a limited area of the image contour as a data area of the bar-shaped splicing two-dimensional code; constructing a coordinate system, and then generating a plurality of code blocks in the data area based on the coordinate system; strip-shaped lines are arranged in a data area and used for storing data information; and splicing the code blocks provided with the strip-shaped lines to generate a two-dimensional code image of which the image contour is in a boundary shape. The invention aims to generate a two-dimensional code which can be spliced at will through the method, and because the boundary of the code is not fixed, the code can be spliced according to a specific application scene.
Description
technical field [0001] The invention belongs to the technical field of two-dimensional codes, and in particular relates to a method for generating and decoding bar-shaped spliced two-dimensional codes. Background technique [0002] With the rapid development of science and technology, two-dimensional codes are more and more widely used in daily life, especially in the fields of mobile payment and online social networking. has gained rapid popularity. [0003] In the existing two-dimensional code technology, when designing a two-dimensional code, the two-dimensional code is placed in a fixed area by setting a fixed-shaped positioning graphic or a fixed-shaped code area boundary. For example, a QR code is a rectangular frame. The small program code is a circle. When decoding, it is necessary to perform image search and positioning on fixed-shaped positioning blocks to determine the position of the code area, and then correct and normalize the image through the positional re...
