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
The present invention relates to a kind of ticket image collecting method and equipment thereof, relate in particular to a kind of bill anti-counterfeit spectral analysis information digitalization collection and recognition methods and equipment.
Background technology
Existing ticket image collecting method in kind mainly is to gather by flat bed scanner, two kinds of equipment of cylinder high speed scanner, uses the acquisition method of these two kinds of equipment to have some problems in actual applications.
The first, can not discern image that exciting light produces.At present a lot of bills have all adopted anti-counterfeiting technology, and for example, the image that utilizes anti-forgery ink, the exciting light of special substance (metal wire, tinsel etc.) under ultraviolet light, infrared light irradiation to form carries out false proof.But present bill harvester all can not be gathered above-mentioned image, thereby influences the normal realization of bill anti-counterfeit function.
The second, comprise multiple design and color in the common whole bill, and crucial anti-counterfeiting image wherein---as seal etc.---often with other pattern or colour contamination together, caused very big inconvenience so just for the above-mentioned crucial false proof part of identification.
Three, the identification of bill anti-counterfeit information is mainly finished in the identification of the papers of original financial field by manual observation.This mode relies on the bill receiving personnel to finish the whole process of distinguishing substantially, and having increased the people is the risk of distinguishing.
The 4th, more can't preserve the image of actual items anti-counterfeiting information actual distinguish in the process without any the preservation of distinguishing anti-counterfeiting information, the inquiry after occurring in order to problem.
In addition, present existing flatbed scanner scan mode exists problems, for example, picture quality is not up to standard, there is distortion in the image of being gathered, sweep time is long.
Therefore need a kind of automatic bill image collection device and method to realize high-quality, gather image and solve above technical matters simultaneously apace.
Summary of the invention
The purpose of this invention is to provide the method and the equipment thereof of a kind of high-quality, quick bill collection image, it can carry out the collection of the image of exciting light or specific color based on spectral analysis.
To achieve these goals, the method for collection image of the present invention is as follows.
The concrete steps of ticket image collecting method of the present invention are as follows:
Step 1: shine the bill that has anti-forgery ink, false proof material or particular color pattern with ultraviolet light, infrared light or visible light respectively;
Step 2: gather the exciting light of described anti-forgery ink, false proof material or the formed image of reflected light of particular color pattern;
Step 3: the bill image of reference standard is identified in the image that forms in the described step 2 and judges the true and false of described bill.
Preferably, described ultraviolet light wavelength is 365 or 254nm.
Preferably, adopt ultraviolet light, infrared light and visible light to shine bill simultaneously.
Preferably, adopt CCD or CMOS industrial camera to gather image.
Preferably, the process of the identification papers in the described step 3 is as follows:
S1 is transported to computing machine with the image that identifies;
S2 isolates described ultraviolet light, infrared light or radiation of visible light and presents the image part from overall image;
S3 is with described ultraviolet light, infrared light or image that radiation of visible light presents part and the standard picture contrast that prestores;
S4 judges the true and false and preserves identifying information.
Bill anti-counterfeit spectral analysis information digitalization of the present invention is gathered the equipment with identification, and its external structure comprises cabinet, top cover, bill put area, power input interface, Data Input Interface, shooting trigger; Its inner structure comprises skeleton, ultraviolet source, infrared light supply and visible light source, plane mirror, CCD or CMOS industrial camera, digital processing circuit and the data transmission integrated circuit board of optical device.
Preferably, its CMOS industrial camera adopts the sensitization adapter and the high-resolution lens of 3,000,000 pixels, and plane mirror is disposed direction and is 45 degree that make progress.
Beneficial effect of the present invention is as follows.
At first, produce exciting light, the image that exciting light forms is gathered and discerned, thereby realized the recognition function of anti-counterfeiting information thereby can shine to special anti-counterfeiting substances.
Secondly, by adopt with bill in the light of color same color of key images shine bill, then in irradiation process, described image will fully reflect this specific color, and other parts in the bill will absorb irradiates light.Therefore, in the image of gathering under this condition, this image will be brighter more and remarkable than other parts in the bill.And then the image of this image can be extracted from the integral ticket image, thereby carry out truth identification or obtain expressing information by the software extraction system.
Once more, can preserve information after the bill image gathered and the identification.
At last, ticket image collecting method of the present invention is improved the quality of images acquired on the one hand,
On the other hand, the acquisition time of images acquired is shortened a lot, acquisition time was less than 1 second, and collecting efficiency is significantly improved.
Description of drawings
Fig. 1 is the synoptic diagram of the equipment that uses in the ticket image collecting method of the present invention.
Fig. 2 is a process flow diagram of distinguishing true from false of the present invention.
Embodiment
Below further specify by reference accompanying drawing 1 and 2 pairs of method and apparatus of the present invention of accompanying drawing.
Bill collecting device of the present invention comprises: optical imagery structure 1, CMOS industrial camera 2, plane mirror 3, the float glass 4 that adds anti-reflection film, ultraviolet, infrared and visible light source 5, panel 6, trigger button 7, top cover 8, digital processing circuit and data transmission integrated circuit board.
The assembled mode of this equipment is as follows.Described optical imagery structure 1, form by a rectangular parallelepiped framework, two parallel placements of rectangular parallelepiped assembly are used on rectangular parallelepiped framework base, and connect by four-bladed vane, vertical fixing CMOS industrial camera 2 on four-bladed vane, camera lens is parallel with four-bladed vane, with plane mirror 3 towards camera lens, minute surface is fixing to camera lens pointing direction inclination 45 degree, is fixed on the four-bladed vane by support, and stile is supported by four cylinders, top cover 8 is by the rectangle board making, hollow out in the middle of the sheet material is carried out inlaying of float glass 4, and float glass 4 tops are panel 6, above plane mirror 3, one circle light source 5 is installed around the rectangular parallelepiped framework inside casing, and described data transmission integrated circuit board has power supply input and USB output interface, and described digital processing circuit comprises the digital processing circuit that is used for handling and exporting the image that is collected by industrial camera.Trigger button 7 is set on top cover.
