Embodiment approach 1

[0084] figure 1 It is a structural representation of a concentric circular graphic locator according to an embodiment of the present invention figure 1 ,Such as figure 1 As shown, it includes central circle 1, ring one 2, and ring two 3.

[0085] The centers of the center circle 1, ring 1 2, and ring 2 3 overlap, and the radii expand in turn;

[0086] The width of the ring one 2 is 2 times of the radius of the central circle 1, and the width of the ring two 3 is 1 time of the radius of the central circle 1. The ring width of any one of the rings is an integer multiple of the radius of the central circle, or a fraction of an integer; when there are multiple rings, they are adjacent to each other 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.

[0087] The colors of two adjacent central circles 1 and / or rings are different; when there are multiple central circles 1 and ...

Embodiment approach 2

[0092] figure 2 It is a structural representation of a concentric circular graphic locator according to 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.

[0093] The difference between Embodiment 2 and Embodiment 1 is that the central circle 1 of Embodiment 2 is black. In Embodiment 2, there are 3 rings outside the central circle 1 of Embodiment 2. The width of Ring 1 2 and Ring 2 3 is different.

[0094] Such as figure 2 As shown, it includes 3 layers of rings and a central circle. From the outer black ring, through the center of the central circle, to the line segment on the other side of the outer black ring, the colors passed are: black, white , black, white, black, white, black, and the ratio of the number of pixels in each color segment is 1:2:1:2:1:2:1.

Embodiment approach 3

[0096] image 3 It is a structural representation 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-counterfeit mark main body 21, a concentric circular graphic locator one 22, a concentric circular graphic locator two 23, a concentric circular graphic locator three 24, and a random anti-counterfeiting marking point 29.

[0097] image 3 , the inside of the dotted line box is divided into random anti-counterfeiting mark main body 21.

[0098] On the main body 21 of the random anti-counterfeiting mark, a group of random anti-counterfeiting marking points 29 are randomly distributed; the quantity, position and size of the random anti-counterfeiting marking points 29 are random. It should be noted that the random anti-counterfeiting mark point 29 is located within the scope of the random anti-counterfeiting mark main body 21; generally it does not o...

Abstract

A random anti-counterfeit mark with a graphic locator comprises a random anti-counterfeit mark main body, and a graphic locator located at a vertex and / or a midpoint and / or a mark point of an area where the random anti-counterfeit mark main body is located; the random anti-counterfeit mark main body comprises a random anti-counterfeit mark main body and a graphic locator. The graphic locator comprises a concentric circular graphics locator and / or a concentric square graphics locator. The invention provides a random anti-counterfeit mark with a graphic locator, which can be read manually and can be read automatically by computer image recognition. A computer can automatically identify the position, area and size of the anti-counterfeit mark or a two-dimensional code in an image.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to a random anti-counterfeiting mark, a two-dimensional code and its identification and positioning method and device. Background technique [0002] The existing Chinese patent 201520198228.6 proposes an anti-counterfeiting marking device capable of making random anti-counterfeiting marks. The existing Chinese patent 201520654356.7 proposes a random marking head without a rigid inner core, which can be used with a random anti-counterfeiting mark making device to make random anti-counterfeiting marks. Existing Chinese patents 2015201975795, 2015201982286, 2015202001174, 2015205590062, 2015210834029, 2015211359747, and 201521137990X respectively propose a random anti-counterfeiting marking device or component. None of the above relates to the aspect of random anti-counterfeiting marks with graphic locators. [0003] Now widely used two-dimensional code, set a nested box...
