A label template generation method and anti-counterfeiting label anti-transfer method

Abstract

The invention discloses a label template generation method and an anti-counterfeit label transfer prevention method, which include the following steps: step S1, using the label template generation method to generate a label template; step S2, determining a plurality of outer labels in the label template Expanding branches; step S3, embedding object graphics that can be recognized by a computer vision system in each externally expanding branch to form an original label pattern; step S4, preparing an anti-counterfeit label according to the original label pattern; step S5, using a computer vision system to identify For the object graphics in the anti-counterfeiting label, compare the identified object graphics with the object graphics in the original label pattern, and judge whether the anti-counterfeiting label has been illegally transferred according to the comparison result. Compared with the prior art, the beneficial effect of the present invention is that the anti-transfer ability of the present invention is stronger, and its layer structure is simpler, and at the same time helps to simplify the manufacturing process, and can better meet customization requirements.

Description

technical field [0001] The invention relates to a label anti-counterfeit method based on computer vision inspection technology, in particular to a label template generation method and an anti-counterfeit label transfer prevention method. Background technique [0002] Pasting "anti-counterfeiting labels" has become the most popular anti-counterfeiting method in the current market because of its low cost, fast speed, and loose coupling with the production line. But for a long time, anti-counterfeiting labels have been labeled as "low-end products" in the field of anti-counterfeiting. One of the most important reasons is the lack of "anti-transfer" capabilities. For comparison, a new anti-counterfeiting technology "material fingerprint anti-counterfeiting" has emerged in recent years. The "fingerprint" here refers to the characteristic texture of the product's appearance, and these characteristic textures cannot be transferred. But the anti-counterfeiting label is different. I...

Problems solved by technology

The first disadvantage is the high cost. The more precise the multi-layer structure, the greater the cost of the multi-layer material itself and the precise process, which will weaken the cost advantage of the label.

The second disadvantage is poor compatibility. For example, if customers want to customize personalized labels that match their own brand styles, "multi-layer structure labels" are difficult to achieve compatibility due to the limitations of their structure.

[0004] But in fact, the reason why anti-counterfeiting labels can still occupy the mainstream in the market is mainly because of the shortcomings of high cost and low universality of "material fingerprint anti-counterfeiting"
