Color identification code and decoding method thereof

Abstract

The invention provides a color identification code and a decoding method thereof, comprises a positioning point, a color reference layer, a coding layer, a data layer and an end mark layer, wherein the positioning point is located at a center position of an identification code, the color reference layer surrounds the positioning point, the coding layer surrounds the color reference layer, the datalayer surrounds the coding layer, and the end mark layer surrounds the data layer; Wherein the color reference layer, the encoding layer, the data layer and the end mark layer are respectively composed of a plurality of color points, and the positioning points and each color point contain data information of a preset number of bits. The invention can improve the data capacity of the unit area ofthe identification code, and does not need complex operations such as stretching and twisting when the identification code is scanned, and the identification speed is faster.

Description

technical field [0001] The invention relates to the technical field of two-dimensional codes, in particular to a color identification code and a decoding method thereof. Background technique [0002] QR code technology was born in the 1940s, but it was really widely used in the 1980s. In recent years, due to the promotion of mobile payment, the application of QR code has become more and more extensive. The two-dimensional code generally adopts a rectangular structure, so it has two dimensions of information, and its information volume is much larger than that of ordinary barcode technology. With the development of smart mobile terminals, standard cameras can support the scanning of QR codes and barcodes, making the application of QR codes very convenient and reliable. [0003] At present, two-dimensional codes have also shown great advantages in product identification. They carry a large amount of information and can directly generate website links. Therefore, two-dimensio...

Problems solved by technology

[0004] However, the existing two-dimensional codes only mark data in black and white, and the information storage capacity per unit area is small, and the rectangular structure requires image processing, correction of offset and distortion, etc., the workload is heavy, and the recognition speed is slow

In addition, since each QR code needs to accurately locate the starting point and data point, and there are many data points, the image pixel area to be scanned is large, and only large-area active focusing can accurately extract data

This also leads to the fact that in practical applications, it is often necessary to adjust the focus and image size multiple times to complete the scan. The scan speed is slow and it is very inconvenient to use.
