Problems solved by technology
[0005] However, the QR code in the prior art has the following disadvantages: 1) the recognition algorithm is relatively complicated, resulting in slower scanning speed and longer recognition time; 2) the pattern occupies a large area, and it is difficult to print a two-dimensional code on it when the product is small; 3) It cannot be used when the scanning resolution is low (such as 640*480); 4) It cannot scan and recognize multiple QR codes in the same screen at the same time
[0007] However, in some practical application scenarios, some parts have a mutual cooperation relationship and other parts have no cooperation relationship, and the mutual relationship between the above parts needs to be identified during scanning; and the above-mentioned circular two-dimensional recognition When the code is scanned, it is impossible to judge the relationship between the circular two-dimensional identification codes
Therefore, the technology still has shortcomings

Embodiment Construction
[0026] The pattern of the circular two-dimensional identification code of the present invention is introduced below.
[0027] figure 1 The printed pattern of the f-shaped two-dimensional identification code of the present invention is shown, which is composed of an inner inner ring 10 and outer circular arcs 20 and 21 .
[0028] figure 2 It is a schematic diagram of the principle of the above-mentioned circular two-dimensional identification code. The inner ring 10 is a closed ring, and its center is a center point 30, which is the center point of the entire circular two-dimensional identification code pattern. The arcs 20 and 21 have the same center and radius, that is, the arcs 20 and 21 are located on the same outer ring 40, and the center of the outer ring 40 is the center point 30; the radius of the outer ring 40 is the inner ring 10 twice; the outer ring 40 is equally divided into 13 sections, each section is a sector, forming sectors 40a to 40m. figure 2 The six con...

The invention relates to a scanning identification method for a circular two-dimensional identification code combination. A function of judging mutual relations between multiple circular two-dimensional identification codes is realized by scanning a position relation between a straight line from the circle center of a circular two-dimensional identification code and the circle center of another circular two-dimensional identification code. The scanning identification method is particularly applicable to an Internet of things application occasions needing to quickly scan multiple products whichare matched with one another at the same time.
Description
technical field [0001] The invention relates to a scanning recognition method for a combination of circular two-dimensional identification codes, which belongs to the field of the Internet of Things, and more specifically, belongs to the field of computer image intelligent analysis. Background technique [0002] In the industrial chain of the Internet of Things, sensing technology is the core basic technology, and two-dimensional codes are an important component of sensing technology. At present, the two-dimensional code technology has a significant role in promoting the development of the Internet of Things industry. [0003] A two-dimensional code refers to a computer-readable barcode with another dimension extended on the basis of a one-dimensional code. It usually uses black and white patterns, and the data information contained in it can be identified after being scanned by the corresponding device. Common two-dimensional codes include QR codes (Quick Response Matrix C...
