Abstract
The invention relates to a method and device for collecting and indentifying digital information of a bill stamp pattern. The method comprises the following steps of: irradiating a bill by light with the same color as a bill stamp with a special color; collecting an image formed by visible lights which are reflected by the stamp with the special color; and identifying the image by referring to a standard image and judging the authenticity of the bill. Through the method and device provided by the invention, high-quality and fast collection of the image presented by the special color 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 collection and recognition methods and equipment of digital information of bill seal designs.
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, 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.
The second, can not discern image that exciting light produces.At present a lot of bills have all adopted anti-counterfeiting technology, and it generally is to use particular matter as the material of making seal, utilize particular matter to carry out false proof at the image that ultraviolet, the exciting light of non-visible light such as infrared form.But present bill harvester all can not be gathered above-mentioned image, thereby influences the normal realization of bill anti-counterfeit function.
The 3rd, the identification of bill anti-counterfeit information is mainly finished in the papers identification 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 the method for the digital image information of specific color pattern in a kind of automatic extraction bill to solve the problems of the technologies described above effectively.
Summary of the invention
The collection and recognition methods and the equipment that the purpose of this invention is to provide a kind of digital information of bill seal designs.
To achieve these goals, the method for bill specific color image collection is as follows.
Step 1: use the rayed bill identical with the color of bill particular color seal;
Step 2: the formed image of visible light of gathering described particular color seal reflection;
Step 3: the reference standard image is discerned described image and is judged the true and false of described bill.
Preferably, collection of the present invention and recognition methods are simultaneously with ultraviolet or infrared light supply irradiation bill.
Preferably, collection of the present invention and recognition methods adopt CCD or CMOS industrial camera to gather image.
Preferably, the process of the step 3 of collection of the present invention and recognition methods is as follows:
(1) image that identifies is transported to computing machine;
(2) from general image, isolate the image section that seal presented of described particular color;
(3) with the image section that seal presented of described particular color and the standard picture contrast that prestores;
(4) judge the true and false and preserve identifying information.
Preferably, can also isolate ultraviolet light, infrared light irradiation institute in the described step (2) of collection of the present invention and recognition methods, (3) simultaneously and present image section, and with the image comparison that prestores.
The structure of collection of the present invention and identification equipment is as follows.
External structure comprises cabinet, top cover, bill put area, power input interface, Data Input Interface, shooting trigger; Its inner structure comprises skeleton, plane mirror, industrial camera, digital processing circuit and the data transmission integrated circuit board of color LED light source, optical device.
Preferably, it also is provided with ultraviolet and infrared light supply, and described industrial camera adopts the CMOS 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.
Description of drawings
Fig. 1 is that bill seal designs of the present invention is gathered and the recognition methods process flow diagram.
Fig. 2 is the synoptic diagram of bill seal designs collection of the present invention and identification equipment.
Embodiment
Below by reference Fig. 1 and Fig. 2 method of the present invention is further specified.
With with bill in the identical rayed bill of color of red seal, adopt the CMOS sensitization adapter and the high-resolution lens of 3,000,000 pixels, be captured in the image under the condition of this specific red light irradiation.The image that identifies is transported to computing machine, from general image, isolates the image section that this redness seal is presented,, thereby judge the true and false of this bill and preserve identifying information the image of the red seal gathered and the standard picture contrast that prestores.
Below further specify by 2 pairs of equipment of the present invention of reference 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, 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.
45 degree light refraction image-forming principles by uniqueness have reduced the object distance length of actual imaging, thereby have reduced whole equipment volume.The mode that new technology is taken is a kind of technological improvement, can reach the bill image of collection in image acquisition process by light path control.Because the improvement of this acquisition mode, the problem of impelling original linear sweep acquisition mode to exist has obtained solution.
The bill image (being digital information) that identifies is transferred to computing machine.The artificial observation analysis can be carried out then or the application image process software is handled.But by artificial treatment, speed is slow, and inefficiency is differentiated the fault rate height.
