Problems solved by technology

[0005] However, so far, for bulk consumer products, the public has not only never become a participant in the counterfeit inspection of commodities, but even ignores most of the anti-counterfeit labels. There are three main reasons for this: First, the counterfeit inspection technology is complex Or the counterfeit inspection equipment is expensive, and it is difficult for the public to participate in it, and the extremely low participation of the public makes it difficult to form credibility; second, most anti-counterfeiting technologies use one-dimensional or two-dimensional label products as carriers, while anti-counterfeiting labels lower than three-dimensional are all Inevitably, it is easy to be copied, recycled or forged; the third is the cost issue. It is true that many anti-counterfeiting technologies are difficult to crack, but the anti-counterfeiting labels are expensive and difficult to be accepted by commodity manufacturers
[0006] In short, in the current anti-counterfeiting industry, no anti-counterfeiting label has been found that can take into account the following elements at the same time: (1) facilitate the public to participate in large-scale counterfeiting verification; (2) realize pre-sale counterfeiting inspection of products; (3) cannot be copied; (4) Cannot be recycled; (5) Low probability of counterfeiting; (6) Low cost; (7) Applicable to a variety of commodities in all walks of life; (8) High cost of counterfeiting

Embodiment 1

[0081] Such as figure 1 As shown, an anti-counterfeiting label based on trace three-dimensional random graphics includes two basic components: three three-dimensional random graphics 1 and a three-dimensional carrier 2 capable of accommodating all three-dimensional random graphics 1. The three-dimensional carrier 2 is made of PC material and can Visible light is transmitted so that the three-dimensional random graphics can be recognized by image recognition equipment; the positions of the three-dimensional random graphics 1 in the three-dimensional carrier 2 are randomly distributed, and the center of gravity coordinates of the three three-dimensional random graphics 1 are on three parallel but different planes The three-dimensional random figures 1 have different outer surface patterns, colors, shapes, and volumes between each pair; the image characteristics of the combination of the three-dimensional random figures 1 and the three-dimensional carrier 2 are recorded in the dat...

Embodiment 2

[0083] Such as figure 1 As shown, an anti-counterfeiting label based on trace three-dimensional random graphics includes two basic components: three three-dimensional random graphics 1; and a three-dimensional carrier 2 capable of accommodating all three-dimensional random graphics 1. Each three-dimensional random figure 1 Including 5-6 random surfaces, the area of ​​each surface is 2-10 square millimeters at random, each surface is printed with different patterns, 3 three-dimensional random graphics 1 whose center of gravity coordinates are on 3 parallel but different planes The maximum distance between any two points on the outer surface of a single three-dimensional random figure 1 does not exceed 0.6cm; the three-dimensional carrier 2 is made of PMMA material, and the three-dimensional carrier 2 can transmit visible light so that the three-dimensional random figure 1 can be recognized by image recognition equipment ; In the photos obtained by shooting the three-dimensiona...

Embodiment 3

[0085] Such as figure 1 As shown, an anti-counterfeiting label based on trace three-dimensional random graphics includes two basic components: three three-dimensional random graphics 1 and a three-dimensional carrier 2 capable of accommodating all three-dimensional random graphics 1. The three-dimensional carrier 2 is made of PS material and can Through visible light so that the three-dimensional random graphics can be recognized by image recognition equipment; the positions of the three-dimensional random graphics 1 in the three-dimensional carrier 2 are randomly distributed, and there are three three-dimensional random graphics 1 whose center of gravity coordinates are in three non-parallel On a plane; the maximum distance between any two points on the outer surface of a single three-dimensional random figure 1 does not exceed 0.7cm; two pairs of three-dimensional random figures 1 have different outer surface patterns, shapes, and volumes; the three-dimensional random figure ...

Abstract

The invention relates to an anti-counterfeit label based on trace amount three-dimensional random graphics. The label includes 1-3 three-dimensional random graphics and a three-dimensional carrier capable of accommodating all the three-dimensional random graphics. The three-dimensional random graphics in the three-dimensional carrier are randomly distributed; image features of combination of the three-dimensional random graphics and the three-dimensional carrier are recorded in a database; and the three-dimensional random graphics are used for being compared and recognized by an image recognition device. Pre-sale inspection on a counterfeit of goods can be achieved; and the label has the characteristics of non-replicability and non-recyclability, and provides the possibility for the publicto participate in inspection on the counterfeit of the goods.

Description

technical field [0001] The invention relates to a three-dimensional anti-counterfeiting label based on trace three-dimensional random graphics, which belongs to the field of anti-counterfeiting. [0002] The term "mechanical connection" includes riveting, bolt connection, key pin connection, elastic snap connection and other methods. [0003] The term "welding": refers to the use of electrical energy, chemical energy, mechanical energy to join two objects together. Background technique [0004] After years of development of anti-counterfeiting technology, many categories have been formed, such as laser holographic film, laser holographic anodized aluminum film, laser holographic plus fluorescent anti-counterfeiting film, flexible laser holographic anti-counterfeiting film, optical color-changing interference film, optical retro-reflective film, nuclear micro Anti-counterfeiting film technology represented by porous film, optical lens three-dimensional display anti-counterfe...
