Embodiment approach 1
[0167] figure 1 It is a schematic diagram of the structure of a concentric circular ring graphic locator according to an embodiment of the present invention figure 1 ,Such as figure 1 As shown, it includes a central circle 1, a circle 1, and a circle two 3.
[0168] The centers of center circle 1, circle 1, 2, circle 2 3 overlap, and the radii expand in sequence;
[0169] The width of ring one 2 is twice the radius of center circle 1, and the width of ring two 3 is twice the radius of center circle 1. The ring width of any one of the rings is an integer multiple of the radius of the central circle, or one part of an integer; when multiple rings are adjacent, layer by layer; preferably, the width of the ring is 1 radius of the central circle 2 times and 1 times alternate from the inner layer to the outer layer.
[0170] The colors of two adjacent center circles 1 and / or rings are different; when there are multiple center circles 1 and rings, the colors of each center circle 1 or r...
Embodiment approach 2
[0175] figure 2 It is a schematic diagram of the structure of a concentric circular ring graphic locator in another embodiment of the present invention figure 2 ,Such as figure 2 As shown, it includes central circle 1, circle one 2, circle two 3, circle three 4.
[0176] The difference between the second embodiment and the first embodiment is that the center circle 1 of the second embodiment is black, and the second embodiment has 3 rings on the outside of the center circle 1 of the second embodiment, the width of the second ring 2 and the second ring 3 different.
[0177] Such as figure 2 As shown, it contains 3 layers of rings and a center circle, starting from the outer black ring, passing through the center of the center circle, and reaching the line segment on the other side of the outer black ring. The colors that go through are: black, white , Black, white, black, white, black, and the ratio of the number of pixels in each segment is 1:2:1:2:1:2:1.
Embodiment approach 3
[0179] image 3 It is a schematic structural diagram of a random anti-counterfeiting mark with a graphic locator according to another embodiment of the present invention figure 1 ,Such as image 3 As shown, it includes a random anti-counterfeiting mark main body 21, a concentric circular ring graphic locator 22, a concentric circular circular graphic locator two 23, a concentric circular ring graphic locator 24, and a random anti-counterfeiting mark 29.
[0180] image 3 In, the inside of the dashed box is divided into a random anti-counterfeiting mark body 21.
[0181] On the random anti-counterfeiting mark body 21, a set of random anti-counterfeiting mark points 29 are randomly distributed; the number, position, and size of the random anti-counterfeiting mark points 29 are random. It should be noted that the random anti-counterfeiting mark point 29 is located within the range of the random anti-counterfeiting mark body 21; generally, it does not overlap with the graphic locator, ...
