Method and device for digitally collecting and indentifying anti-counterfeiting spectroscopic analysis information of bill

Abstract

The invention relates to a method and device for digitally collecting and indentifying anti-counterfeiting spectroscopic analysis information of a bill. The method comprises the following steps of: respectively irradiating a bill with anti-counterfeiting ink, anti-counterfeiting material or a special color pattern by using ultraviolet lights, infrared rays or visible lights; collecting an image formed by laser lights of the anti-counterfeiting ink and the anti-counterfeiting material or reflected lights of the special color pattern; and identifying the image by referring to a standard bill image and judging the authenticity of the bill. Through the method and device provided by the invention, high-quality and fast collection of the bill image can be realized.

Description

technical field [0001] The invention relates to a bill image collection method and equipment thereof, in particular to a bill anti-counterfeit spectral analysis information digital collection and identification method and equipment. Background technique [0002] The existing physical bill image collection method is mainly collected by flat-bed scanners and roller high-speed scanners. There are some problems in the practical application of the collection methods using these two devices. [0003] First, the image generated by the excitation light cannot be recognized. At present, many bills have adopted anti-counterfeiting technology, for example, using anti-counterfeiting inks, special materials (metal wires, metal wires, etc.) under the irradiation of ultraviolet light and infrared light to form images of excitation light for anti-counterfeiting. However, none of the current bill collection devices can collect the above-mentioned images, thus affecting the normal realizatio...

AI Technical Summary

Problems solved by technology

However, none of the current bill collection devices can collect the above-mentioned images, thus affecting the normal realization of the bill anti-counterfeiting function

[0004] Second, usually the entire bill includes a variety of patterns and colors, and the key anti-counterfeiting images-such as seals-are often mixed with other patterns or colors, which causes great difficulties in identifying the above-mentioned key anti-counterfeiting parts. big inconvenience

This method basically relies on the bill accepting personnel to complete the entire identification process, which increases the risk of manual identification

[0006] Fourth, there is no preservation of any identification anti-counterfeiting information during the actual identification process, and it is even impossible to save the image of the actual bill anti-counterfeiting information for query after the problem occurs

[0007] In addition, there are many problems in the existing scanning methods of flatbed scanners, for example, the image quality is not up to standard, the collected images are deformed, and the scanning time is too long
