Problems solved by technology

[0003] First, 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
[0004] Second, the image generated by the excitation light cannot be recognized
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

Embodiment Construction

[0032] Below by referring to the attached figure 1 and figure 2 The method and equipment of the present invention are further described.

[0033] The bill is irradiated with light of the same color as the red stamp in the bill, and a 3 million-pixel CMOS photosensitive adapter and a high-resolution lens are used to collect images under the condition of the specific red light. Send the recognized image to the computer, separate the image part presented by the red seal from the overall image, compare the image of the collected red seal with the pre-stored standard image, so as to judge the authenticity of the bill and save the identification information .

[0034] The bill collection device of the present invention includes: optical imaging structure 1, CMOS industrial camera 2, plane mirror 3, float glass 4 with antireflection film, visible light source 5, panel 6, trigger button 7, top cover 8, digital processing circuit and data transfer boards.

Abstract

The invention relates to an acquisition and identification method of specified color pattern digitization information on a bill and equipment thereof. The method comprises the following steps: using light which has a same color with the color of the specified color pattern on the bill to illuminate the bill; collecting an image formed by visible light which is generated through the specified color pattern reflection; extracting image information of the specified color pattern. By using the method and the equipment of the invention, the digital image information of the specified color pattern on the bill can be extracted.

Description

technical field [0001] The invention relates to a bill image information collection method and equipment thereof, in particular to a collection and recognition method and equipment thereof for digitized information of a specified color pattern on a bill. 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, 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. [0004] Second, the image generated by the excitation light cannot be recognized. At present, many bills have adopted anti-counterfeiting technology, which generally uses sp...
