Embodiment 1
[0082] Such as figure 1 As shown, a three-dimensional anti-counterfeiting label based on a small amount of random bubbles includes two basic components: a random bubble 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 penetrate Visible light so that the random bubbles 1 in it can be recognized by the image recognition device; the position of the random bubbles 1 in the three-dimensional carrier 2 is random; the image features of the random bubbles 1 and the three-dimensional carrier 2 are recorded in the database for being Image recognition equipment contrast recognition; 3D anti-counterfeiting labels are divided into front and back, where the front is used to be scanned and recognized by image recognition equipment, and the back is the surface of the 3D anti-counterfeiting label opposite to the physical position of the front. Shooting the 3D anti-counterfeit label from any different a...
Embodiment 2
[0084] Such as figure 1 As shown, a three-dimensional anti-counterfeiting label based on a small amount of random bubbles includes two basic components: 2-3 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 pass through visible light so that the random bubbles 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 bubble 1 occupies 3D anti-counterfeiting The proportion of the total area of the label is 50-60%; 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 ima...
Embodiment 3
[0086] Such as figure 1 As shown, a three-dimensional anti-counterfeiting label based on a small amount of random bubbles includes two basic components: 2-3 random bubbles and a three-dimensional carrier 2 that can accommodate all random bubbles 1. The three-dimensional carrier 2 is made of PS material and can be transparent. 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 the coordinates of the centers of gravity of all random bubbles 1 are on parallel but different planes. The distance is not particularly limited; the image features of the random bubble 1 and 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, and the front is used for being imaged The recognition device scan...
