Embodiment Construction
[0034] refer to figure 1 , the flow chart of the first embodiment of the detection method of the anti-counterfeit product of the present invention, the method includes:
[0035] Step 101: Obtaining the first image of the anti-counterfeit product under different predetermined light sources at the same irradiation angle and the second image of the anti-counterfeit product under the same predetermined light source and different irradiation angles respectively;
[0036] Among them, acquisition refers to obtaining images of anti-counterfeiting elements and traces of use of anti-counterfeiting products by taking pictures, scanning, copying, etc.;
[0037] Anti-counterfeiting elements on anti-counterfeiting products include dominant and invisible ones. Invisible anti-counterfeiting elements should be checked and identified by optical, electrical, magnetic, radiation, chemical and other methods. Some anti-counterfeiting points combine multiple anti-counterfeiting elements to improve ...

The invention discloses a detection method and a detection device of an anti-counterfeit product, comprising: separately acquiring a first image of the anti-counterfeit product under the irradiation of different predetermined light sources at the same irradiation angle and a second image of the anti-counterfeit product under the same predetermined light source and different irradiation angles ; Extract at least one anti-counterfeit element information and at least one use trace information in the first image and the second image; match the detection feature information of at least one anti-counterfeit element or at least one use trace with the corresponding pre-stored feature information; if all the above The results of the judgments are all true, then the output anti-counterfeiting product is genuine and is the only result. Through the above method, the present invention can obtain different images of anti-counterfeiting products under various illuminations and different angles, extract multiple feature information and match pre-stored feature information, and perform multiple anti-counterfeiting composite verifications on the same anti-counterfeiting point to judge anti-counterfeiting products The authenticity of the judgment results is more accurate.
Description
technical field [0001] The invention relates to the field of anti-counterfeit products, in particular to a method for detecting anti-counterfeit products and a detection device thereof. Background technique [0002] With the development of printing technology, anti-counterfeit products have become more diverse, and it has become common to determine the authenticity of things by printing anti-counterfeit elements, such as RMB, trademarks and various bills; however, imitation, forgery and cloning of anti-counterfeit products And other technologies are also constantly improving, so the detection of anti-counterfeiting products is particularly important. [0003] In the prior art, most of the detection of anti-counterfeit products is to detect the material of the anti-counterfeit elements on the anti-counterfeit products and the images under light. [0004] However, these characteristic information exist as a single independent one, and each anti-counterfeiting element uses its...
