Embodiment 1
[0080] Such as figure 1 As shown, a three-dimensional anti-counterfeiting label based on random bubbles includes two basic components: 10-18 random bubbles 1 and a three-dimensional carrier 2 that can accommodate all random bubbles 1. The three-dimensional carrier 2 is made of PC material and can be transparent Through visible light so that the random bubbles in it can be identified by image recognition equipment; the positions of the random bubbles 1 in the three-dimensional carrier 2 are randomly distributed, and at least three random bubbles 1 have their center of gravity coordinates on three parallel but different planes; The image features of the random bubble 1 combined with the three-dimensional carrier 2 are recorded in the database for comparison and recognition by the image recognition device; the three-dimensional anti-counterfeiting label is divided into a front and a back, where the front is used for scanning and recognition by the image recognition device, and the...
Embodiment 2
[0082] Such as figure 1 As shown, a three-dimensional anti-counterfeiting label based on random bubbles includes two basic components: 15-25 random bubbles 1 ; and a three-dimensional carrier 2 capable of accommodating all random bubbles 1 . The three-dimensional carrier 2 is made of PMMA material, and the three-dimensional carrier 2 can transmit visible light so that the random bubbles 1 in it can be recognized by the image recognition equipment; in the photos obtained by taking the three-dimensional anti-counterfeiting label from any angle, the area of the random bubbles 1 occupies three-dimensional The proportion of the total area of the anti-counterfeiting label is 80-90%; the front of the three-dimensional anti-counterfeiting label is photographed by an image acquisition device, and the image characteristics of the combination of the random bubble 1 and the three-dimensional carrier 2 are obtained and recorded in the database for comparison and recognition by the image...
Embodiment 3
[0084] Such as figure 1 As shown, a three-dimensional anti-counterfeiting label based on random bubbles includes two basic components: 20-25 random bubbles 1 and a three-dimensional carrier 2 capable of accommodating all random bubbles 1. The three-dimensional carrier 2 is made of PS material and can be transparent Through visible light so that the random bubbles in it can be recognized by image recognition equipment; the positions of random bubbles 1 in the three-dimensional carrier 2 are randomly distributed, and there are at least 7 random bubbles 1 whose center of gravity coordinates are on 7 non-parallel planes, The distance between two bubbles is not particularly limited; the image features of random bubbles 1 and three-dimensional carrier 2 are recorded in the database for comparison and identification by image recognition equipment; three-dimensional anti-counterfeiting labels are divided into front and back, of which The front side is used to be scanned and recognized...
