Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings.
Example one
The embodiment of the invention provides a paper money identification method for an ATM device. The method may be performed by a banknote recognition arrangement for an ATM apparatus, wherein the arrangement may be implemented by software and/or hardware, and may generally be integrated in an ATM apparatus. Fig. 1 is a schematic flow chart of a banknote recognition method for an ATM apparatus according to an embodiment of the present invention, as shown in fig. 1, the method includes:
and S110, responding to an event that the first paper money to be detected is transmitted to the paper money identification module from the temporary storage part, and determining a second infrared light source which is positioned behind a first infrared light source started in the last money detection process of the paper money identification module in the starting sequence list as a current infrared light source in the current money detection process.
In this embodiment, based on a start sequence list of infrared light sources preset by a bank worker or a default start sequence list of infrared light sources set by a developer, a second infrared light source sequenced in the start sequence list after a first infrared light source started in a last currency detection process is determined as a current infrared light source started in the current currency detection process. Specifically, a target number (one or more) of infrared light sources may be arbitrarily selected from the infrared light sources located after the first infrared light source turned on in the last banknote checking process in the turn-on sequence list as the current infrared light source for the current banknote checking, or the target number of infrared light sources may be sequentially selected from the infrared light sources located after the first infrared light source turned on in the last banknote checking process in the turn-on sequence list and adjacent to the first infrared light source as the current infrared light source for the current banknote checking according to the sequence in the turn-on sequence list. The target number of the second infrared light sources started in the currency detection process can be set as required, and only one second infrared light source is started in the currency detection process as an example.
In consideration of the consistency of the use times of the infrared light sources, it is preferable that the second infrared light source located after and adjacent to the first infrared light source turned on in the last money detecting process in the turn-on sequence table is determined as the current infrared light source turned on in the current money detecting process. Here, it should be noted that if the first infrared light source turned on in the last banknote checking process is located at the end of the turn-on sequence list, the infrared light source located at the start position of the turn-on sequence list may be regarded as the second infrared light source located after the first infrared light source and adjacent to the first infrared light source.
For example, the current banknote checking process and the previous banknote checking process may be determined based on different bank accounts, different banknote depositing times, different banknote identification contents, or different banknotes, that is, the reverse banknote checking process of the previous bank account (i.e., the banknote checking process in which the banknote is transmitted from the temporary storage portion to the banknote identification module), the reverse banknote checking process of the previous deposit operation, the forward banknote checking process of the current deposit operation, or the reverse banknote checking process of the previous first banknote to be checked may be regarded as the previous banknote checking process, and accordingly, the reverse banknote checking process of the current bank account, the reverse banknote checking process of the current deposit operation, or the reverse banknote checking process of the current first banknote to be checked may be regarded as the current banknote checking process, which is not limited herein.
In order to reduce the complexity of controlling the opening of different infrared light sources and improve the consistency of the use times of different infrared light sources, optionally, if all the infrared light sources are not opened in the forward currency detection, the forward currency detection process of the deposit operation can be regarded as the last currency detection process, the reverse currency detection process of the deposit operation can be regarded as the current currency detection process, and the infrared light sources which are not opened in the forward currency detection process are selected according to an opening sequence list in the current currency detection process to illuminate and acquire the infrared image of the first paper currency to be detected; if all infrared light sources are turned on for positive currency detection, the last deposit operation or the reverse currency detection process of the last bank account can be regarded as the last currency detection process, the deposit operation or the reverse currency detection process of the current bank account can be regarded as the current currency detection process, and in the current currency detection process, infrared light sources which are not turned on in the last currency detection process are selected according to an opening sequence list to illuminate and collect infrared images of the first paper currency to be detected.
In this embodiment, it may be determined whether the first banknote to be inspected is transferred from the escrow unit to the banknote recognition module based on the traffic currently processed by the ATM apparatus or based on the transfer direction of the first banknote to be inspected (i.e., it is determined whether the current banknote verification process is the reverse banknote verification process). For example, the current banknote checking process may be determined as the reverse banknote checking process when a deposit confirmation instruction from the user is received, or may be determined as the reverse banknote checking process when the transmission direction of the first banknote to be checked is detected to be from the temporary storage portion to the banknote recognition module. At the moment, correspondingly, the ATM equipment can transmit the first paper money to be checked in the temporary storage part to the paper money identification module when receiving a deposit confirmation instruction of a user; or, the ATM device may also check the transport direction of the paper money to be checked entering the paper money recognition module, and determine the paper money to be checked, which has the transport direction from the temporary storage section to the paper money recognition module, as the first paper money to be checked. The paper money detection module is used for detecting the paper money to be detected, wherein the transmission direction of the paper money can be determined based on the running direction of a paper money transmission channel in the paper money identification module, and the running direction of the paper money transmission channel is determined as the transmission direction of the paper money to be detected; the method can also be based on the sequence determination that the correlation sensor in the paper money identification module is shielded by the first paper money to be detected in the reverse money detection process, if the time that the correlation sensor close to one side of the temporary storage part in the paper money identification module is shielded by the first paper money in the current money detection process is earlier than the time that the correlation sensor far away from one side of the temporary storage part in the paper money identification module is shielded by the first paper money to be detected in the current money detection process, the current money detection process is determined to be the reverse money detection process, and the paper money to be detected entering the paper money identification module in the reverse money detection process is determined to be the first paper money to be detected transmitted to the paper money identification module from the temporary. The paper money identification module can be arranged between the paper money storage port and the temporary storage part.
And S120, sequentially adopting the current infrared light source and the visible light source in the paper money identification module to perform line scanning illumination on the first paper money to be detected transmitted to the paper money identification module, and detecting the circulation of the first paper money to be detected.
In this embodiment, the current infrared light source and the visible light source may be used to illuminate the first banknote to be inspected at a time, obtain the infrared image and the visible light image of the first banknote to be inspected, and further determine whether the first banknote to be inspected is a negotiable banknote based on the infrared image and the visible light image.
The infrared image and the visible image collected during the current banknote validation process may be a reflection image and/or a transmission image. Correspondingly, if the collected image is a transmission image (an infrared transmission image and/or a visible light transmission image), only one corresponding light source (one current infrared light source and/or one visible light source) can be started in the current currency detection process; if the collected image is a reflection image, one or two corresponding light sources (one or two current infrared light sources and/or one or two visible light sources) respectively positioned at two sides of the first paper money to be detected can be started in the current currency detection process, preferably two corresponding light sources respectively positioned at two sides of the first paper money to be detected can be started, such as two current infrared light sources and/or visible light sources respectively positioned above and below the plane of the first paper money to be detected, so as to ensure that the infrared reflection image and/or the visible light reflection image at two sides of the first paper money to be detected can be collected. In consideration of the practicability of each image and the wear degree of each light source, it is preferable that the circulation of the first banknote to be inspected is determined based on the infrared transmission image and the visible light reflection image (hereinafter referred to as visible light image) of the first banknote to be inspected, and at this time, correspondingly, only one current infrared light source located on one side of the first banknote to be inspected is turned on to collect the infrared transmission image of the first banknote to be inspected, and two visible light sources respectively located on two sides of the first banknote to be inspected (two visible light sources are located on two sides of the plane where the first banknote to be inspected is located) are turned on to collect the visible light images of the front side and the back side of the first banknote to be inspected.
After the circulation of the first banknote to be tested is determined, the banknote information of the first banknote to be tested which can be circulated and the banknote information of the first banknote to be tested which cannot be circulated are marked in different marking modes respectively, and the first banknote to be tested which can be circulated and the first banknote to be tested which cannot be circulated are conveyed to the same position or different positions to be stored. Preferably, after determining the currency of the first banknote to be tested, the first banknote to be tested which is currency capable and the first banknote to be tested which is not currency capable can be respectively transported to different positions, so that the workload required by the following bank staff for sorting the first banknotes to be tested which are currency different is reduced. At this time, after the checking the currency of the bill to be checked, the method may further include: if the first paper money to be detected is detected to be the negotiable paper money, the first paper money to be detected is conveyed to a circulating paper money box; and if the first paper money to be detected is detected to be non-negotiable paper money, conveying the first paper money to be detected to a waste paper money box.
In the technical scheme for identifying the paper money in the ATM, when the paper money to be inspected is transmitted to the paper money identification module from the temporary storage part, a second infrared light source which is positioned behind a first infrared light source started in the last money detection process of the paper money identification module in an opening sequence list is determined as a current infrared light source in the current money detection process, the current infrared light source and a visible light source in the paper money identification module are sequentially adopted to perform line scanning illumination on the paper money to be inspected transmitted to the paper money identification module, and the currency of the paper money to be inspected is inspected. By adopting the technical scheme, the paper currency circulation is checked by adopting the infrared light source different from the previous time, so that the use frequency of the infrared light source can be reduced, the loss of the infrared light source is reduced, the service life of the paper currency recognition module is prolonged, and the maintenance cost of the ATM equipment is reduced.
Example two
Fig. 2 is a flowchart illustrating a banknote recognition method for an ATM apparatus according to a second embodiment of the present invention. The present embodiment is optimized on the basis of the above-mentioned embodiment, and in this embodiment, "sequentially adopt the current infrared light source and the visible light source in the banknote recognition module to perform line scanning illumination on the first banknote to be tested transmitted to the banknote recognition module, and test the currency of the first banknote to be tested" is optimized as follows: sequentially adopting the current infrared light source and the visible light source in the paper money identification module to perform line scanning illumination on the first paper money to be detected transmitted to the paper money identification module, and acquiring an infrared transmission image and a visible light image of the first paper money to be detected; and determining the circulation of the first paper currency to be tested according to the infrared transmission image and the visible light image.
Further, in response to the event that the banknote is transmitted from the temporary storage unit to the banknote recognition module, determining a second infrared light source in the start sequence list, which is located after the first infrared light source started in the last banknote verification process of the banknote recognition module, as being before the current infrared light source in the current banknote verification process, the method may further include: responding to an event that a second paper money to be inspected is transmitted to the paper money identification module from the paper money storage port, sequentially adopting an infrared light source and an ultraviolet light source in the paper money identification module to perform line scanning illumination on the second paper money to be inspected, and acquiring an infrared image and an ultraviolet reflection image of the second paper money to be inspected, wherein the infrared image comprises an infrared reflection image and/or an infrared transmission image; and determining the authenticity of the second paper money to be detected according to the infrared image and the ultraviolet reflection image, and transmitting the second paper money to be detected which is determined to be genuine to a temporary storage part.
Correspondingly, as shown in fig. 2, the banknote recognition method for an ATM apparatus according to the present embodiment includes:
s210, respond to the second and wait to examine the paper currency and transmit to paper currency recognition module' S incident by the paper money mouth, adopt infrared light source and ultraviolet light source in the paper currency recognition module in proper order the second is waited to examine the paper currency and is carried out the line scanning illumination, gathers the infrared image and the ultraviolet reflection image of paper currency are waited to examine to the second, infrared image includes infrared reflection image and/or infrared transmission image.
In this embodiment, when the reflection image (infrared reflection image or ultraviolet reflection image) of the second banknote to be detected is collected, corresponding light sources (infrared light source or ultraviolet light source) located above and below the plane of the second banknote to be detected can be simultaneously turned on to scan and illuminate the banknote in a line manner, so as to obtain images of the front and back surfaces of the banknote; when collecting the infrared transmission image of the second banknote to be inspected, only the infrared light source located above or below the plane of the second banknote to be inspected can be turned on. Correspondingly, when the infrared image of the second paper money to be inspected is acquired, if the infrared reflection image (or the infrared reflection image and the infrared transmission image) of the second paper money to be inspected needs to be acquired, the infrared light sources above and below the plane of the second paper money to be inspected can be simultaneously turned on; if only the infrared transmission image of the second paper money to be inspected needs to be acquired, only the infrared light source above or below the plane of the second paper money to be inspected can be turned on, at the moment, the infrared light source behind the infrared light source turned on in the last time money detecting process of the paper money identification module in the turn-on sequence list can be preferably selected to illuminate and acquire the infrared transmission image of the paper money, and therefore the service life of the infrared light source is prolonged.
In this embodiment, it may be determined whether the second banknote to be inspected is transmitted from the banknote storing port to the banknote recognition module (i.e. whether the current banknote checking process is the forward banknote checking process) based on the currently processed service of the ATM apparatus or based on the transmission direction of the second banknote to be inspected. For example, the current banknote checking process may be determined as the forward banknote checking process when a deposit confirmation request of the user is received, or may be determined as the forward banknote checking process when the transmission direction of the second banknote to be checked is detected to be from the banknote deposit port to the banknote recognition module. At the moment, correspondingly, when receiving a deposit request of a user, the ATM equipment can transmit a second banknote to be detected, which is put into the banknote deposit port by the user, to the banknote identification module from the banknote deposit port; or, the ATM device may also check a transport direction of the paper money to be checked entering the paper money recognition module, and determine the paper money to be checked as the second paper money to be checked, the transport direction being from the paper money deposit port to the paper money recognition module. The paper money detection module is used for detecting the paper money to be detected, wherein the transmission direction of the paper money can be determined based on the running direction of a paper money transmission channel in the paper money identification module, and the running direction of the paper money transmission channel is determined as the transmission direction of the paper money to be detected; the method can also be based on the sequence determination that the correlation sensor in the paper money identification module is shielded by the first paper money to be detected in the current money checking process, if the time that the correlation sensor close to one side of the money storage port in the paper money identification module is shielded by the first paper money in the current money checking process is earlier than the time that the correlation sensor far away from one side of the money storage port in the paper money identification module is shielded by the first paper money to be detected in the current money checking process, the current money checking process is determined to be a forward money checking process, and the paper money to be detected entering the paper money identification module in the forward money checking process is determined to be the second paper money to be detected transmitted to the paper money identification module from the money storage port.
S220, determining the authenticity of the second paper money to be detected according to the infrared image and the ultraviolet reflection image, and transmitting the second paper money to be detected which is determined to be genuine to a temporary storage part.
Accordingly, if the second banknote to be inspected is determined to be a counterfeit banknote, the second banknote to be inspected, which is determined to be a counterfeit banknote, may be returned to the banknote deposit port.
In this embodiment, the authenticity of the second banknote to be inspected can be determined based on the infrared image and the ultraviolet reflection image of the second banknote to be inspected. Illustratively, when the authenticity of the second paper money to be inspected is determined, the anti-counterfeiting feature areas in the infrared image and the ultraviolet reflection image of the second paper money to be inspected can be respectively intercepted, the anti-counterfeiting feature information of each anti-counterfeiting feature area is obtained, the anti-counterfeiting feature information is respectively matched with the standard anti-counterfeiting feature information of the anti-counterfeiting feature area to which the anti-counterfeiting feature information belongs to obtain the sub-matching degree of each anti-counterfeiting feature area, the anti-counterfeiting feature matching degree of the second paper money to be inspected is further obtained based on the weight calculation of the anti-counterfeiting feature information when the authenticity of the paper money is determined, the second paper money to be inspected with the anti-counterfeiting feature matching degree higher than or equal to a set matching degree threshold value is determined as a true paper money, and the second paper money to be inspected with the anti-counterfeiting feature. The threshold of the degree of matching can be set as required, for example, it can be set to 0.9 or 0.7.
And S230, in response to the event that the first to-be-detected paper currency is transmitted to the paper currency identification module from the temporary storage part, determining a second infrared light source which is positioned behind a first infrared light source started in the last currency detection process of the paper currency identification module in the starting sequence list as the current infrared light source in the current currency detection process.
S240, line scanning illumination is carried out on the first paper money to be inspected transmitted to the paper money identification module by sequentially adopting the current infrared light source and the visible light source in the paper money identification module, and an infrared transmission image and a visible light image of the first paper money to be inspected are collected.
In this embodiment, the light source parameters of the infrared light source, such as the spectrum band, the light emitting duration, the light emitting intensity, and the like of the infrared light emitted by the infrared light source, which are turned on in the forward banknote checking process (i.e., the banknote checking process for determining the authenticity of the banknote) and the reverse banknote checking process (i.e., the banknote checking process for determining the currency of the banknote), may be the same or different. Because the light loss when the light passes through the paper money and reaches the image sensor is generally higher than the light loss when the light reaches the image sensor through the reflection of the paper money, optionally, if the truth of the second paper money to be detected is determined based on the infrared reflection image and the ultraviolet emission image of the second paper money to be detected in the forward money detection process, the luminous intensity of the second infrared light source started in the reverse money detection process can be higher than the luminous intensity of the infrared light source started in the forward money detection process; if the authenticity of the second paper money to be detected is determined based on the infrared transmission image and the ultraviolet emission image of the second paper money to be detected in the forward currency detection process, the same infrared light source luminous intensity can be adopted for reverse currency detection; if the authenticity of the second paper money to be detected is determined based on the infrared transmission image, the infrared reflection image and the ultraviolet reflection image of the second paper money to be detected in the forward paper money detection process, the luminous intensity of the infrared light source started in the reverse paper money detection process can be larger than or equal to the luminous intensity of the infrared light source started in the first paper money detection process, and therefore the consistency of the brightness of the infrared images obtained in the forward paper money detection process and the reverse paper money detection process is improved.
And S250, determining the currency of the first paper money to be tested according to the infrared transmission image and the visible light image.
In this embodiment, the old and new degree, the damage degree, the stain blocking degree and the like of the first banknote to be inspected can be determined based on the difference between the gray value of the corresponding sub-region in the first gray scale image corresponding to the infrared transmission image and the standard gray value of the corresponding sub-region in the second gray scale image corresponding to the visible light image, thereby further determining the circulation grade of the first banknote to be tested based on the priorities of the infrared image and the visible image when determining the circulation of the banknote and the weights of the freshness degree, the breakage degree, the stain blocking degree and the like of the banknote when calculating the circulation of the banknote, and further determines a first banknote to be inspected whose circulation level is greater than or equal to the circulation level threshold value as a circulatable banknote based on the circulation level and a circulation level threshold value of a circulatable banknote (or a non-circulatable banknote), and determining the first banknote to be inspected whose circulation level is less than the circulation level threshold value as a non-circulatable banknote. Among them, the circulation level threshold value of the circulatable banknotes (or the non-circulatable banknotes) can be set as required.
