Embodiment 1
[0081] Such as figure 1 As shown, a three-dimensional anti-counterfeiting label based on random droplets includes two basic components: 10-18 random droplets 1 and a three-dimensional carrier 2 capable of accommodating all random droplets 1, and the three-dimensional carrier 2 is made of PC material , can pass through visible light so that the random droplet 1 can be identified by the image recognition device; the positions of the random droplet 1 in the three-dimensional carrier 2 are randomly distributed, and there are at least 3 random droplet 1 whose center of gravity coordinates are in 3 On parallel but different planes; the image features of random droplet 1 and three-dimensional carrier 2 are recorded in the database for comparison and recognition by image recognition equipment; three-dimensional anti-counterfeiting labels are divided into front and back, and the front is used for being recognized by image recognition equipment. The image recognition equipment scans and...
Embodiment 2
[0083] Such as figure 1 As shown, a three-dimensional anti-counterfeiting label based on random droplets includes two basic components: 15-25 random droplets 1 ; and a three-dimensional carrier 2 capable of accommodating all random droplets 1 . The three-dimensional carrier 2 is made of PMMA material, and the three-dimensional carrier 2 can pass through visible light so that the random droplets 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 droplet 1 occupies The proportion of the total area of the three-dimensional 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 droplet 1 and the three-dimensional carrier 2 are obtained and recorded in the database for use by the image recognition dev...
Embodiment 3
[0085] Such as figure 1 As shown, a three-dimensional anti-counterfeiting label based on random droplets includes two basic components: 20-25 random droplets 1 and a three-dimensional carrier 2 capable of accommodating all random droplets. The three-dimensional carrier 2 is made of PS material, It can transmit visible light so that the random droplets 1 can be recognized by the image recognition equipment; the positions of the random droplets 1 in the three-dimensional carrier 2 are randomly distributed, and there are at least 7 random droplets 1 whose center of gravity coordinates are in 7 different positions. On a parallel plane, the distance between two droplets is not particularly limited; the image features of the combination of random droplets 1 and 3D carrier 2 are recorded in the database for comparison and identification by image recognition equipment; 3D anti-counterfeiting The label is divided into front and back, where the front is used to be scanned and recognized...
