Dot-matrix graph anti-counterfeiting detector and operating method thereof

Abstract

The invention provides a dot-matrix graph anti-counterfeiting detector. The dot-matrix graph anti-counterfeiting detector comprises a dot-matrix graph scanning part, a storage module, a multimedia file playing part and a master control module, wherein the dot-matrix graph scanning part is used for acquiring a dot-matrix graph image and analyzes the dot-matrix graph image into image coding data; the storage module is used for storing and searching for multimedia files corresponding to the image coding data; the multimedia file playing part is used for playing the multimedia files; the master control module is used for controlling and coordinating all the modules, and processing signals input into all the modules. The operating method of the dot-matrix graph anti-counterfeiting detector includes the steps that an infrared spectrum is emitted out and irradiated to dot-matrix graphs on the surface of an article; an image frame of a complete dot-matrix graph image is converted into image coding data; whether multimedia files corresponding to the image coding data exist in the storage module or not is judged, and corresponding information is played according to the judgment result. According to the dot-matrix graph anti-counterfeiting detector and the operating method of the dot-matrix graph anti-counterfeiting detector, dot-matrix graph on printed articles can be conveniently and effectively recognized, the recognition result is displayed in the mode of audio, characters, videos, pictures and the like, and the manifestation pattern is made to be various and vivid.

Description

technical field [0001] The invention relates to an anti-counterfeit detector, in particular to an anti-counterfeit detector with a dot matrix pattern and an operation method thereof. Background technique [0002] Dot-matrix graphics technology is a kind of anti-counterfeiting mark that has emerged in recent years. It processes digital information into dot-matrix graphics through encoding, and implants them on paper, film, metal and other media through printing, and uses special anti-counterfeiting detectors to accurately identify them. Identification of anti-counterfeiting technology. It has the advantages of low cost, portable application, extremely difficult to crack, reliable verification, and massive information. However, the existing detectors (such as bill discriminators, special card recognizers, etc.) used to recognize dot matrix patterns present the recognition results in the form of voice broadcast or text, which are relatively simple and not rich and vivid enough...
