Problems solved by technology

[0004] Although several anti-counterfeiting technologies have been developed at present, with the popularization and rapid dissemination of information, the existing anti-counterfeiting technologies are more and more easy to be imitated, and it is difficult to ensure their uniqueness. For the rights and interests of consumers and the reputation of manufacturers, how to Developing more diversified or higher-threshold anti-counterfeiting technologies has become a top priority

Embodiment Construction

[0034] See figure 1 , Which is a schematic diagram of the system concept of the optical system of the present invention in a preferred embodiment. The optical system 1 includes a light-emitting source 11, a reflective structured light generating element 12, and a sensing and determining device 13, and the reflective structured light generating element 12 is used to be installed (such as attached or printed) on the target 2 to be tested. The light beam 41 provided by the light-emitting source 11 is projected thereon; wherein the reflective structured light generating element 12 generates structure light 42 when the light beam 41 provided by the light-emitting source 11 is projected thereon, and is reflected to a The tested surface 3 makes the tested surface 3 present the tested pattern 43 corresponding to the reflective structured light generating element 12, and the sensing determination device 13 is used to sense the tested pattern 43 presented on the tested surface 3, and acco...

Abstract

The invention provides an optical system and a method for determining the class of a tested object by using the optical system. The optical system comprises a reflective structure light generation element and an induction and determination apparatus, wherein the reflective structure light generation element is arranged on one tested object and used for generating structure light after receiving a light beam provided by a light emitting source and reflects the structure light to a tested surface; a test pattern appears on the tested surface when the structure light is projected to the tested surface; and the induction and determination apparatus is used for inducing the test pattern appearing on the tested surface and determines the class of the tested object according to the induced test pattern. According to the invention, structure light is used for determining the class of the tested object, so effective anti-counterfeiting is realized.

Description

Technical field [0001] The present invention relates to an optical system, in particular to an optical system using structured light and a method for judging the class of a target to be measured using the optical system. Background technique [0002] In recent years, counterfeiting has often occurred in product manufacturing and marketing. Counterfeiting refers to the unauthorized use of other operators’ unique and well-known registered trademarks, product packaging, and product packaging in order to compete for competitive advantage. Decorations, names, or various quality marks that cause consumer confusion and market confusion, and seek illegitimate benefits, are extremely harmful to market competition. [0003] In order to allow the public to clearly identify the authenticity of goods, there are many anti-counterfeit labels on the market, for example, laser anti-counterfeit labels, which can change the viewing angle and light source to see the preset color effects or graphics, o...
