detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

first embodiment

Referring to Fig. 1, it shows a flow chart of a banknote authenticity verification method according to an embodiment of the present invention, which may specifically include the following steps:

Step 101, driving the molecular sensor to emit near-infrared light to the paper area of the banknote.

Step 102, receiving paper characteristic light reflected by the paper region on the near-infrared light through the molecular sensor.

In specific implementation, the embodiments of the present invention can be applied in mobile terminals, for example, mobile phones, PDAs (Personal Digital Assistants, personal digital assistants), laptop computers, palmtop computers, etc., and the present invention is not limited thereto.

These mobile terminals can support operating systems such as Android (Android), IOS, WindowsPhone, and windows.

In the embodiment of the present invention, the mobile terminal is equipped with a molecular sensor, and the molecular sensor is connected to the processor through a MIPI (Mobile Industry Processor Interface, mobile industry processor interface) interface and an I2C (Inter-Integrated Circuit, internal integrated circuit) interface. Send a handshake signal to the processor through the I2C interface to notify the processor that there is data to be transmitted, and then transmit the detected data to the processor through the MIPI interface for further processing.

As shown in Figure 2, the molecular sensor can emit near-infrared light (near IR) 201 to the sample to be detected. 202 absorbs energy and transitions from the original ground state vibration (rotation) kinetic energy level to a higher energy vibration (rotation) kinetic energy level. Molecules 202 undergo vibration and rotation energy level transitions after absorbing infrared radiation, and the light at this wavelength is absorbed by the sample .

Therefore, the molecular sensor receives the light reflected by the sample, analyzes the attenuation degree of the emitted light, and reflects the characteristics of the relative vibration and molecular rotation between atoms in the sample molecule, thereby identifying the molecular structure of the sample.

In a specific implementation, as shown in FIG. 3 , the molecular sensor 300 may include a light source 301 and a receiver 302 .

Wherein, the light source 301 may emit near-infrared light. Generally, the effective wavelength of the near-infrared light may be 720 nm˜1070 nm. For example, the light source 301 may be an LED (Light-Emitting Diode, light-emitting diode) emitting tube.

The receiver 302 can be a photosensitive sensor that receives light reflected from the sample. Usually, the sensitivity of the receiver 302 is less than 10 nm, for example, 8 nm.

In an example of an embodiment of the present invention, the receiver is provided with a multi-stage dispersion device.

As shown in Fig. 4, a slit 421 is arranged inside the receiver, the reflective mirror 422 is used as the first-stage dispersive device, the grating 423 is used as the second-stage dispersive device, and the reflective mirror 424 is used as the third-stage dispersive device, The emitted light 410 enters the slit 421 , is reflected by the reflector 422 and then enters the grating 423 , is diffracted by the grating 423 and then enters the reflector 424 , and is reflected by the reflector 424 to collect a vibration spectrum.

In this example, the receiver can reflect and diffract the reflected light multiple times in a short distance, which not only ensures a wide range of wavelengths obtained, but also shortens the distance. Therefore, it can achieve high resolution while ensuring , to reduce the size of the molecular sensor.

In another example of the embodiment of the present invention, as shown in FIG. 5 , the receiver sequentially includes a primary lens array 501, a filter array 502, a secondary lens array 503, a microhole array 504, and a support structure array along the direction of incident light. 505. A sensor array 506.

The light emitted by the sample is irradiated on the primary lens array 501 to generate diffused light, and the diffused light is irradiated on the filter array 502 , and the microhole array 504 prevents crosstalk between filters in the filter array 502 . The light passing through the filter array 502 is angle-coded, and it passes through the secondary lens array 503, and the secondary lens array 503 performs Fourier transform on the angle-coded light, transforming it into space-coded light, and finally The light reaches sensor array 506 .

The position of the sensor unit in the sensor array 506 is related to the optical axis of the lens array corresponding to the light wavelength, and the wavelength of a certain pixel position is determined based on the optical axis of the lens array related to the pixel position. The sensor unit records the light intensity, which corresponds to the position-resolved light wavelength.

In this example, the receiver has a straight optical axis and a short optical path. The straight optical axis and short optical path can make the molecular sensor smaller and lower cost, which can be integrated into the mobile terminal, and can have enough Sensitivity and resolution to obtain spectrograms of samples at multiple band wavelengths.

Of course, the structure of the above molecular sensor is only an example, and other molecular sensor structures can be set according to actual conditions when implementing the embodiment of the present invention, which is not limited by the embodiment of the present invention. In addition, in addition to the structure of the molecular sensor described above, those skilled in the art may also adopt other structures of the molecular sensor according to actual needs, which is not limited in the embodiments of the present invention.

At present, banknotes are usually printed on banknote paper, which is a special paper that can be used for anti-counterfeiting. It is generally produced by licensed manufacturers and strictly controlled, so it is difficult to circulate in the market.

The main raw materials of banknote printing paper are cotton fiber and high-quality wood pulp. Some countries also add their own unique products or chemical elements to the pulp. The waters of the Allier River, the printing paper of the franc, and so on. Of course, some artificially prepared or synthesized special markers can also be added.

The composition of banknote printing paper is generally unique, so that the composition of banknotes is also unique. For example, banknote printing paper for printing RMB is made of about 70% cotton fiber mixed with other special wood fibers. Therefore, it can be based on the quality of banknote paper. (such as banknote printing paper) components to verify the authenticity of banknotes.

In banknotes, especially the edge area, there is a paper area, that is, an area where the banknote printing paper is exposed, without metal wires, ink, etc. being blocked.

It should be noted that the paper area can be set by those skilled in the art according to the actual situation. Different countries, different denominations, and different versions of banknotes may have different paper areas, which are not limited by the embodiment of the present invention. .

For example, as shown in FIG. 6 , on the back of the fifth set of RMB with a denomination of 100 yuan, areas 601 , 602 , 603 , and 604 can be set as paper areas.

In the embodiment of the present invention, the user can hold the mobile terminal, face the molecular sensor to the paper area of the banknote to be verified, and control the molecular sensor to emit near-infrared light of a certain wavelength to the paper area, and the molecules in the paper area absorb some The radiation of the frequency reflects the rest of the light to the molecular sensor, and the molecular sensor receives the paper characteristic light carrying the paper characteristic.

Step 103, drawing a paper infrared spectrogram by using the paper characteristic light.

When the infrared light of a certain frequency passes through the molecule, it is absorbed by the bonds of the same vibration frequency in the molecule, and the curve of the recorded transmittance is called the infrared spectrum.

In one representation of the infrared spectrogram, the abscissa is the wavelength λ (μm) and/or the wave number 1/λ (cm ⁻¹ ), and the ordinate is the absorbance A.

In another representation of the infrared spectrogram, the abscissa is the wavelength λ (μm) and/or the wave number 1/λ (cm ^-1 ), and the ordinate is the percent transmittance T% (that is, the light transmittance through the sample percentage).

The molecular sensor faces a certain sample to emit near-infrared light, and receives the reflected light, and the infrared spectrum can also be drawn by using the emitted light.

For example, as shown in Figure 7, the molecular sensor faces the desktop to emit near-infrared light. The table has different components, such as wood, paint, etc., and different molecular bonds will respond to near-infrared light with different wavelengths, so that The reflected light can be used to create an infrared spectrum.

In the embodiment of the present invention, the paper characteristic light reflected by the paper area may be used to draw an infrared spectrum diagram to obtain the paper infrared spectrum diagram.

Step 104, using the paper infrared spectrogram to identify the paper composition of the banknote.

By measuring the attenuation of near-infrared light of different wavelengths after being reflected back through the infrared spectrum of the paper, it can reflect the characteristics of the composition of the banknote paper (such as banknote printing paper), determine whether the banknote paper is banknote printing paper, and thus judge The authenticity of banknotes.

In the embodiment of the present invention, in a specific implementation, the paper infrared spectrogram may be matched with a preset reference infrared spectrogram.

When the matching is successful, the component corresponding to the reference infrared spectrum is extracted as the paper component of the banknote.

In one of the ways, a spectrogram database can be established on the server, and infrared spectrograms of a large number of samples can be stored in the spectrogram database. The samples can be recorded with composition, for example, carbon content 50%, oxygen content 30%, etc. Wait.

The mobile terminal can upload the paper infrared spectrum to the server, and the server can use the stored infrared spectrum as a reference infrared spectrum, and calculate the similarity with the paper infrared spectrum, if the similarity is higher than the preset threshold, Then it can be considered that the two match successfully, otherwise, it is considered that the two match failed.

In order to speed up the matching rate, the infrared spectrum corresponding to the sample of the banknote-related type (such as paper, fiber, etc.) can be retrieved as a reference infrared spectrum.

Of course, the mobile terminal can also store the cell spectral library locally, and use the infrared spectrum stored in the cell spectral library as a reference infrared spectrum, and match it with the paper infrared spectrum, which is not limited in this embodiment of the present invention.

Step 105, matching the paper component with the target paper component of the real currency to obtain a matching result.

In a specific implementation, one or more target paper components of real currency may be requested from the server to be matched with the paper components.

Since the paper component of real currency is volatile, its target paper component can be set as a range, and if the paper component falls within this range, the two can be considered to match, otherwise, the two do not match.

Step 106, determine the authenticity of the banknote according to the matching result.

In one instance, the banknote is determined to be genuine currency when the paper composition successfully matches the target paper composition of the genuine currency.

In another instance, the banknote is determined to be counterfeit when the paper composition fails to match the target paper composition of genuine currency.

If the two match successfully, it means that the currency to be detected has the same paper composition as the real currency, and the currency to be detected can be considered as real currency, that is, a real banknote.

If the two match successfully, it means that the currency to be detected has different paper components from the real currency, and the currency to be detected can be considered as counterfeit currency, that is, counterfeit banknotes.

In this way, in the embodiment of the present invention, by configuring the molecular sensor in the mobile terminal, the molecular sensor emits near-infrared light to the paper area of the banknote and receives the paper characteristic light reflected by it, and draws a paper infrared spectrogram on it to identify Its paper composition is matched with the target paper composition of real currency to verify the authenticity of the banknote. Since the paper composition of banknotes is generally unique and strictly controlled, it is difficult to circulate in the market. Therefore, it is difficult for criminals to The paper used for counterfeiting and printing banknotes makes the paper composition of real currency and counterfeit currency quite different. Molecular sensors can be used to detect the molecular characteristics of banknote paper, thereby accurately verifying the authenticity of the banknote. The mobile terminal is easy to carry , users can easily verify the authenticity of banknotes, avoid manually verifying the authenticity of banknotes, greatly reduce the circulation of counterfeit banknotes, reduce losses to users, and slow down possible economic problems.

second embodiment

Referring to FIG. 8 , it shows a flow chart of another banknote authenticity verification method according to an embodiment of the present invention, which is applied in a mobile terminal, and the mobile terminal is equipped with a molecular sensor. The method may specifically include the following steps:

Step 801, driving the molecular sensor to emit near-infrared light to the paper area of the banknote.

In one embodiment of the present invention, the mobile terminal is equipped with a camera, and the camera can be invoked to collect image data on the banknote when the molecular sensor faces the banknote to be verified.

Load the detection area on the image data, and detect the paper area in the detection area.

Wherein, there is a detection point in the detection area, and the detection point can indicate the direction in which the molecular sensor emits near-infrared light.

In one case, the molecular sensor is not rotatable, so the detection point is relatively fixed, and the user can move the mobile terminal according to the position of the detection point so that the detection point falls into the paper area.

In another case, the molecular sensor can be rotated within a certain range, and the detection point can be rotated within a certain range. If a paper area is detected, the mobile terminal can rotate the molecular sensor so that the detection point falls into the paper area middle.

When the detection point is located in the paper area, the actuating molecular sensor emits near-infrared light along the detection point.

For example, as shown in Figure 9, when the user faces the banknote with the mobile terminal, the rear camera is driven to collect image data, the detection area 901 is loaded on the image data, the edge of the banknote is detected by the edge detection algorithm in the detection area 901, and then the edge Detect the white Unicom area and identify the paper area. If the detection point 902 is located in the paper area, emit near-infrared light toward the detection point 902 so that the near-infrared light can reach the paper area.

Step 802, receiving paper characteristic light reflected by the paper region on the near-infrared light through the molecular sensor.

Step 803, using the characteristic light of the paper to draw a paper infrared spectrogram.

In one embodiment of the present invention, since near-infrared light has a certain degree of penetration, and banknotes are generally thin, near-infrared light may penetrate banknotes and shoot to other objects, causing the reflected paper characteristic light to be mixed with other objects characteristics.

Therefore, in the embodiment of the present invention, the banknote can be placed on a supporting object, and the supporting object can be an object that reflects light, for example, an object with a smooth surface such as a mirror.

The mobile terminal can obtain the characteristic light of the object that emits infrared light to the supporting object and reflects it.

It should be noted that no banknote is placed on the support at this time, that is, the characteristic light of the object generally carries the characteristics of the support object, but does not carry the paper quality of the banknote.

In one way, the user can face the molecular sensor to the supporting object, control the molecular sensor to emit infrared light and receive the reflected object characteristic light.

In another manner, object characteristic light reflected by infrared rays of some commonly used supporting objects may be stored locally in the server and/or the mobile terminal in advance.

The user can select the information of the supporting object (such as type, name, etc.) on the mobile terminal, and query the object characteristic light corresponding to the supporting object locally on the server and/or the mobile terminal.

At this time, the mobile terminal has paper characteristic light when a banknote is placed and object characteristic light when no banknote is placed on the same supporting object.

On the one hand, the first infrared spectrogram is drawn by using the characteristic light of the object.

On the other hand, the second infrared spectrogram is drawn using paper characteristic light.

Subtract the first infrared spectrum from the second infrared spectrum to obtain the paper infrared spectrum. At this time, the spectrum after subtraction is relatively pure, which can reduce the influence caused by the characteristics of other objects mixed in the characteristic light of paper.

Of course, in addition to spectral subtraction, paper characteristic light may also be directly used to draw a paper infrared spectrum, which is not limited in this embodiment of the present invention.

Step 804, determine the currency information corresponding to the banknote.

In a specific implementation, since the banknote printing paper used by different banknotes is different, the currency information of the banknote can be determined, for example, the type (such as RMB, US dollar, British pound, etc.), version (such as the fifth edition of RMB, etc.), Face value (such as 100, 50, 20, 10, etc.), etc., so as to distinguish different banknotes for authenticity verification.

In one case, the user may enter currency information directly.

In another case, currency information can be identified by identifying language, numbers representing face value, and characteristic objects (such as watermarks, portraits, background buildings, etc.) in the image data collected from banknotes.

Step 805, searching for the target infrared spectrogram.

In the embodiment of the present invention, the target infrared spectrogram is an infrared spectrogram obtained by using near-infrared light to detect the paper area of the real currency corresponding to the currency information.

In one manner, a spectrogram database can be established on the server, and infrared spectrograms of a large number of samples are stored in the spectrogram database.

In a specific implementation, the spectrogram database can be maintained by users of the entire network, that is, users of the entire network can use molecular sensors to detect the infrared spectrum of a certain substance, mark the sample's brief information (such as name, variety, etc.), and upload it to The server can also be maintained by a professional testing organization, that is, the professional structure uses infrared spectrometers and other equipment or molecular sensors to detect the infrared spectrum of a substance, and then marks the detailed information of the sample (such as water content, sugar content, etc.), Upload to the server, etc., which are not limited in this embodiment of the present invention.

In this way, the mobile terminal can send the currency information to the server, and the server queries the infrared spectrogram corresponding to the currency information in the spectrogram database, takes it as the target infrared spectrogram, and returns it to the mobile terminal.

In another manner, a cell spectral library can be established for samples in the spectral graph database, and infrared spectral graphs of samples with the same characteristics can be stored in a cell spectral graph library.

For example, build a cell spectrum library for the fifth edition of RMB, build a cell spectrum library for apples in different periods (such as growth, maturity, after picking, etc.), and build a cell spectrum library for human bodies at different body temperatures, wait

Users can download one or more cell spectral libraries from the server according to their needs, and store them locally in the mobile terminal.

For example, if the user runs a store and the circulation of banknotes is very high, he can download the cell spectrum library created for the fifth edition of RMB.

In this manner, the mobile terminal can search for the cell spectral library corresponding to the currency information, and search for the target infrared spectral image corresponding to the currency information in the cell spectral library.

It should be noted that there may be wear and tear of banknotes in the circulation process, resulting in slight changes in the paper quality of banknotes. Therefore, the paper area of the real currency to which the currency information belongs can be tested in different environments such as washing and oil pollution. The target infrared spectrogram, that is, the number of target infrared spectrograms can be one or more.

Step 806, matching the paper infrared spectrogram with the target infrared spectrogram.

Step 807, when the matching is successful, it is determined that the banknote is genuine currency.

Step 808, when the matching fails, it is determined that the banknote is a counterfeit currency.

In a specific implementation, the similarity between the paper infrared spectrogram and one or more target infrared spectrograms can be calculated respectively.

If the similarity is higher than the preset threshold, it can be considered that the two match successfully, otherwise, it is considered that the two match failed.

If the two match successfully, it means that the currency to be detected has the same paper composition as the real currency, and the currency to be detected can be considered as real currency, that is, a real banknote.

If the two match successfully, it means that the currency to be detected has different paper components from the real currency, and the currency to be detected can be considered as counterfeit currency, that is, counterfeit banknotes.

It should be noted that, for the method embodiment, for the sake of simple description, it is expressed as a series of action combinations, but those skilled in the art should know that the embodiment of the present invention is not limited by the described action sequence, because According to the embodiment of the present invention, certain steps may be performed in other orders or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification belong to preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.
