Description
技术领域 technical field
本发明涉及防伪码，尤其涉及一种3D星阵防伪码的生成方法。 The invention relates to an anti-counterfeiting code, in particular to a method for generating a 3D star array anti-counterfeiting code.
背景技术 Background technique
目前流行的防伪方式包括激光防伪、电话防伪、新型材料防伪以及利用RFID进行防伪。其中新型材料防伪有时效性，总是在一段时间后就被人仿制；激光防伪和电话防伪不能作为商品的标识，只能在一定程度上保证该标签的真伪，不能利用它对商品在各流通领域的信息进行记录，因此其防伪效果很有限，市场上已经有大量的假冒商品贴上所谓的激光防伪标签、电话防伪标签迷惑消费者；RFID标签由于难以仿制并且可以作为商品的标识，是一种较严密的防伪方式，但也存在标签价格过高、检验不方便等问题。除此以外，这些防伪手段还有一个共同的特点，不具有普遍性，不易激发消费者防伪的主动性，也就很难形成大家都来防伪的大环境。随着技术的快速发展，逐步出现了3D防伪码，但现有所谓的3D防伪，基本都是激光防伪等策略，并非真正意义上的三维立体防伪策略，部分三维防伪方法，主要依托的仍是二维条形码的策略，无法满足飞速发展的商用3D打印市场对于知识版权保护的需求。因此，现有技术有待于更进一步的改进和发展。 Currently popular anti-counterfeiting methods include laser anti-counterfeiting, telephone anti-counterfeiting, new material anti-counterfeiting and the use of RFID for anti-counterfeiting. Among them, the anti-counterfeiting of new materials is time-sensitive, and they are always imitated after a period of time; laser anti-counterfeiting and telephone anti-counterfeiting cannot be used as labels for commodities, and can only guarantee the authenticity of the labels to a certain extent, and cannot be used to determine the authenticity of commodities in various places. The information in the field of circulation is recorded, so its anti-counterfeiting effect is very limited. There are already a large number of counterfeit goods on the market with so-called laser anti-counterfeiting labels and telephone anti-counterfeiting labels to confuse consumers; RFID labels are difficult to imitate and can be used as product identification. A relatively strict anti-counterfeiting method, but there are also problems such as high label price and inconvenient inspection. In addition, these anti-counterfeiting methods also have a common feature. They are not universal, and it is difficult to stimulate the initiative of consumers in anti-counterfeiting, and it is difficult to form a general environment for everyone to come to anti-counterfeiting. With the rapid development of technology, 3D anti-counterfeiting codes have gradually appeared, but the existing so-called 3D anti-counterfeiting methods are basically laser anti-counterfeiting and other strategies, not three-dimensional anti-counterfeiting strategies in the true sense. Some 3D anti-counterfeiting methods mainly rely on The strategy of two-dimensional barcode cannot meet the demand for intellectual copyright protection in the rapidly developing commercial 3D printing market. Therefore, prior art awaits further improvement and development.
