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 ...
