Annular code and design method thereof

Abstract

The invention discloses an annular code and a design method thereof, belongs to the field of two-dimensional codes and the annular code is sequentially provided with a decorative area, a correction positioning area and a data coding area from inside to outside, the decorative area is filled with decorative patterns for increasing interface attractiveness or transmitting specific information, and the correction positioning area comprises a correction symbol, a positioning symbol and an auxiliary information code which is filled anticlockwise from a starting positioning symbol. Information is stored by fully utilizing the characteristic that the inner and outer ring capacities are increased progressively, and materials are used for filling and beautifying an interface.

Description

technical field [0001] The invention relates to the technical field of two-dimensional codes, in particular to a ring code and a design method thereof. Background technique [0002] Most of the two-dimensional codes in the prior art adopt a rectangle as the appearance shape, and black and white pixel blocks represent the binary codes of the transmitted information in the restricted area of ​​the rectangle. When embedding the code into the graphical interface, place black and white blocks in the coded rectangular area according to the binary information in a certain order, which can ensure that during the decoding process, first scan the locator to determine the area where the two-dimensional code is located, and then identify the black and white pixel blocks according to the specified order. Reads binary data and finally decodes it to deliver information. In order to ensure accurate recognition of the two-dimensional code information, it is necessary to determine the auxili...

The disadvantage of this type of QR code is that it is easy to be decoded in batches and is not suitable for use scenarios with high privacy. In addition, the graphical interface embedded in pixel blocks is not beautiful enough. Even if a stylized algorithm is added to fuse the image display, it can only reduce the pixels Block coverage effect, but still unable to achieve a more comfortable visual effect

[0003] Another common type of QR code is the "chrysanthemum code" used by WeChat applets. Images are placed in the middle of the QR code as a free area to convey specific information and increase aesthetics, while binary codes diverge along the free area in the shape of rays Going out, the ray length and line density of this type of two-dimensional code determine the coding capacity, but the coding area with different lengths from the center of the two-dimensional code encodes the same amount of information, which makes it impossible to fully utilize the theoretical maximum of the outer circle and the inner circle. The fact that the amount of data stored varies, which somewhat limits the length of the required delivery

At the same time, in the appearance of the auxiliary function area, the WeChat QR code still uses a fixed circle as the locator and correction symbol, which also affects its aesthetics to some extent
