Description
Technical field
The present invention relates to Flame Image Process and recognition technology field, be specifically related to a kind of bank note, ticket discrimination method and device.
Background technology
In traditional paper money counter, normally under ultraviolet source irradiation, true and false coin has different fluorescence reactions to the detection of fluorescent characteristics, detects the fluorescence that ejects with the fluorescence reflective sensor.And other color detection are generally collecting devices such as CCD, CMOS, this kind equipment is also adopted in each producer's product in a large number accordingly.And adopt color sensor able to programme or color sensor array to carry out precise quantification, thereby the true and false of identification note more accurately to color.Compare and to analyze the color quantizing value of a sensor with traditional approach, or the color quantizing value of each sensor in the sensor array is carried out combinatory analysis.Detect thereby reach on a large scale, the purpose of multiple spot color analysis because sensor bulk is little, thereby has been simplified hardware configuration, improves the stability of system.
Sensor is exactly energy perception external information and the device that can according to certain rules these information translation be become available signal, simply says to be exactly the device that outer signals is converted to electric signal.In general sensor is made up of induction element and converter two parts.The perception unit is various in style, says with regard to the principle of its perception external information, is divided into the physics class, chemical classes, biological species etc.Wherein the physics class is based on physical influences such as power, heat, light, electricity.
Optical sensor mainly contains light activated element to be formed, and photo-resistor, photodiode, phototriode, photoelectrical coupler, photoelectric cell etc. are arranged at present.With the photoresistance is example, and its important parameter has: photocurrent.Under certain external voltage, when light (1000lx illumination) shines, led the electric current of photoresistance to be called photocurrent.Other parameters also have response time, sensitivity, spectral response, light characteristics etc.
With the photodiode is example, and photodiode all has the sealing of plexiglass lens in appearance, can compile the window of light and photosurface, so the sensitivity of photodiode and response time are much better than photoresistance.Photodiode good linearity in addition, response speed is fast, and the light of wide wavelength range is had higher sensitivity, and noise is low.
Along with the development of modern industry production to high speed, automation direction, the production run midium or long term will be substituted by corresponding color sensor more and more with the active color identification of cause human eye work.For example: the library uses color differentiating that document is classified, and can greatly improve work such as framed bent management and statistics; At packaging industry, the packing of product utilizes different colors or decoration to represent character or the purposes that they are different.Present color sensor is normally independently covering the red, green, blue optical filter that process is revised on the photodiode, then the output electric signal is handled accordingly.
In addition, comprise in the various patent solutions of the currency false distinguishing that Japan, Europe propose, a large amount of be based on reflective image-forming mechanism, CCD, cmos imaging device hardware cost are higher, and volume is relatively large.And fluorescent optical sensor under the constant situation of hardware owing to can only detect the fluorescence of fixed wave length, can't accomplish to detect the fluorescence that other frequencies change to some extent, thereby be of limited application.Therefore, traditional financial machine and tool based on image mode or fluorescent optical sensor has the hardware cost height detecting on color shifting ink variable color, the fluorescent ink fluorescent characteristics, and volume is big, and the system architecture complexity detects that the light wave scope is single to wait inevitable shortcoming.
The performance of existing banknote false distinguishing system directly depends on the imaging characteristics of detected characteristics point.
In the prior art, detect color shifting ink variable color feature, adopt two CMOS to carry out twice bat figure of positive side usually, mixing point if desired just needs 8 CMOS just can finish the above-mentioned figure of adopting function.Carry out color extracting by image processing algorithm then, false proof discriminating.All need collect corresponding image for the false proof point of other colors could continue to handle.
For example traditional again fluoroscopic examination principle is that the papery at Renminbi detects.Renminbi adopts special-purpose paper manufacturing (containing the high-quality cotton more than 85%), counterfeit money adopts the common paper after bleaching is handled to make usually, can occur fluorescence reaction (diffraction goes out the blue light that wavelength is 420-460nm under ultraviolet exciting) under the irradiation of ultraviolet ray (wavelength is the blue light of 365nm) through the bleaching sheet processed, Renminbi does not then have fluorescence reaction.So, the motion banknote is shone and detects with silicon photocell simultaneously the fluorescence reflection of banknote with ultraviolet source, it is true and false to differentiate banknote.For getting rid of the interference of surround lighting, must see through the color filter of wavelength and counterfeit money fluorescence reaction consistent wavelength at mounted on surface one cover of silicon photocell to discrimination.The subject matter of this mode is that the filter effect that detects effect and color filter has much relations, and is numerous because counterfeit money is originated, and different fraud clique makes based on the distinct device unlike material, does not have the consistance of material.Therefore, the fluorescence that inspires will inevitably be different with the inconsistency of material.And traditional fluorescent optical sensor color filter is a fixed wave length, and is fine to the inevitable transmission effects of the fluorescence of identical wavelength, and inevitable variation of other fluorescence transmission effects that wavelength is changed to some extent, thereby may cause the counterfeit money omission.
By the detection of fluorescent ink (as the fluorescence word in the 5th edition Renminbi front) bank note is carried out false distinguishing in the prior art, at wavelength is under the UV-irradiation of 365nm, imitated fluorescent ink printing figure message has been compared tangible aberration with genuine note, produced the fluorescence reaction of the wavelength of varying strength, but detect with the fluorescence reflective sensor with mode the same needs of detecting material, just the color filter on the silicon photocell sees through wavelength needs and genuine notes fluorescence reaction consistent wavelength.Therefore this traditional approach can not detect the accurate scope of wavelength flexibly, and after color filter was fixing, the wavelength band of detection was just determined.And genuine note can cause the fluorescent effect variation because of the reason such as stained that circulation produces, and then is easy to cause the identification of genuine note mistake this moment.
To sum up, there are the high and problems such as the genuine note false drop rate is difficult for reducing, the difficult reduction of counterfeit money loss of system cost in the commercialization stage with traditional approach for the discriminating of bank note.
