Description

TECHNICAL FIELD

The present disclosure relates to money information generation devices, money handling systems, money handling devices, money information generation systems, money information generation methods, and money information generation programs. The present disclosure specifically relates to a money information generation device, a money handling system, a money handling device, a money information generation system, a money information generation method, and a money information generation program capable of generating image information of a virtual money.

BACKGROUND ART

Money handling devices for handling moneys such as coins or notes (banknotes) utilize a plurality of types of sensors mounted on a money recognition unit to acquire features of moneys. Typically, based on comparison of the acquired features of the moneys with template information that serves as a reference of recognition, the types, authenticity, fitness, and the like of the moneys are recognized.
For example, Patent Literatures 1 and 2 disclose an image collation device that collates an image of a money and a plurality of template images corresponding to a variety of moneys to determine the authenticity of the money. In the case of determining the authenticity of coins, this device uses an averaged image obtained by synthesizing a plurality of images of coins of the same type as a template image in order to reduce variation due to individual differences of coins.

SUMMARY OF INVENTION

- Technical Problem

The image collation devices disclosed in Patent Literatures 1 and 2 require obtaining a plurality of images for each denomination from coins circulating in the market in advance and generating a template image from the obtained images.
Also, in the case of determining not the authenticity but the fitness of moneys, a plurality of images is obtained for each denomination from soiled moneys circulating in the market in advance and template information is generated from the obtained images.
When a new series coin is introduced, money handling devices require immediate modification to recognize the new series coin. This causes a demand for immediate generation of template information of the new series coin and application thereof to the money handling devices in the market.
However, in the case of generating template information from real moneys, as in the case of the image collation devices of Patent Literatures 1 and 2, no template information corresponding to soiled moneys can be generated because only new, unused moneys (hereinafter, also referred to as new moneys) are present immediately after introduction of a new series money. This situation after introduction of a new series money prevents recognition of soiled moneys with a high degree of soiling.
Accordingly, even a situation where no real soiled money is available causes a demand for generation of money information (image information and template information) of such a soiled money, i.e., money information of a virtual money corresponding to the soiled money.
The opposite situation where only real soiled moneys are available may cause a demand for generation of template information from a new money.
The present disclosure has been made in view of the above current state of the art and aims to provide a money information generation device, a money handling system, a money handling device, a money information generation system, a money information generation method, and a money information generation program capable of generating coin information of a virtual money corresponding to a money having a desired damage condition even in a situation where no real one of such a money is available.

(Embodiment 1)

With reference to FIG. 1, the following describes the structure of a money information generation device 10a of the present embodiment. The money information generation device 10a has functions equivalent to those of a typical personal computer and includes a control unit (processing unit) 20a as shown in FIG. 1.
As shown in FIG. 1, the control unit 20a has functions of a damage information generation unit 21a, a pattern information generation unit 22a, and a virtual money information generation unit 23a.
The control unit 20a includes, for example, software programs for achieving a variety of processing, a central processing unit (CPU) that executes the software programs, and a variety of hardware devices controlled by the CPU. The software programs and data for running the control unit 20a may be stored in a storage unit.
The units of the control unit 20a shown in FIG. 1 are embodied by causing the CPU of the control unit 20a to execute a money information generation program according to the present embodiment. The money information generation program according to the present embodiment may be preinstalled in the money information generation device 10a, or may be provided to a user as an application program that can run on a general-purpose OS, the application program being stored in a computer-readable recording medium or being provided via a network.
The storage unit includes a storage device such as a hard disk device or a non-volatile memory, and may store a learned model that executes processing relating to generation of damage information, a learned model that executes processing relating to generation of pattern information, and a learned model that executes processing relating to generation of money information of a virtual money.
The damage information generation unit 21a generates (extracts), from an image (input image for style) of a first coin input to the money information generation device 10a, damage information relating to damage of the first coin.
The input image for style (image of the first coin) may be an image of the first coin having a desired damage condition, i.e., a damage condition that the coin is desired to have, and may have any pattern (design, marking). The input image for style may be an image of a coin in circulation having a certain degree of damage (e.g., a damaged coin) or may be an image of a coin without damage (e.g., a new coin).
The pattern information generation unit 22a generates (extracts), from an image (conversion source image) of a second coin input to the money information generation device 10a, pattern information (pattern characteristics) relating to the pattern of the second coin.
The conversion source image (image of the second coin) may be an image of the second coin that is desired to have the damage condition of the input image for style, and may have any damage condition. The conversion source image (image of the second coin) may be an image of a coin without damage (e.g., new coin) or may be an image of a coin in circulation having a certain degree of damage (e.g., damaged coin).
The damage information generated by the damage information generation unit 21a may be information relating to damage of a base of the first coin. In other words, the damage information generation unit 21a may generate (extract) information relating to damage of the base of the first coin from an image (input image for style) of the first coin.
For coins, the term "base" herein commonly refers to the portion excluding the marking of a coin. In other words, a coin commonly includes a base and a marking.
The virtual money information generation unit 23a generates, from the damage information generated by the damage information generation unit 21a and the pattern information generated by the pattern information generation unit 22a, an image (image information) of a virtual coin as a fusion (synthesis) of the damage information and the pattern information. This results in generation of an image of a coin (not an actually existing one but a virtual one) having a damage condition at a degree similar to that of the first coin and having the pattern of the second coin. In other words, even when no second coin having a damage condition at a degree similar to that of the first coin is available, template information relating to the second coin can be generated based on the image of a virtual coin generated as described above.
The term "damage information (information relating to damage)" may refer to information relating to the presence of damage or may refer to information relating to the absence of damage. In the former case, the information may be used to deteriorate the marking or base of the coin.
The term "damage condition" is a term indicating the degree of damage and encompasses not only the cases where damage is present but also the cases where damage is absent.
In other words, in the present embodiment, the first coin may be a coin having damage while the second coin may be a coin having no or little damage and the second coin may be damaged, as a virtual coin, to a degree similar to that of the first coin (the damage condition may be worsened). Alternatively, the first coin may be a coin having no or little damage while the second coin may be a coin having damage and the second coin may not be damaged, as a virtual coin, to a degree similar to that of the first coin (the damage condition may be lessened).
For coins, the term "pattern information (information relating to the pattern)" may refer to information relating to the marking of a coin (e.g., 3D information). The term "marking" herein may refer to something that may change when a coin is damaged or may be something that does not change even when a coin is damaged. Specific examples of the pattern information include information relating to a portion where the way the light hits changes in accordance with the degree of damage, information relating to a portion where the edge information changes in accordance with the degree of damage, and information relating to a portion where the material is changed by damage.
Also, in the present embodiment, an image (image information) may be used as money information. This enables generation of an image of a virtual money corresponding to a second money (real one) having a desired damage condition and enables visual check of the quality of the image.
The damage information generation unit 21a, the pattern information generation unit 22a, and the virtual money information generation unit 23a each may be constructed of a learned model, for example, a learned model utilizing a convolutional neural network (CNN). In this case, the CNN of the virtual money information generation unit 23a may be coupled with the respective CNNs of the damage information generation unit 21a and the pattern information generation unit 22a.
The learned models of the damage information generation unit 21a, the pattern information generation unit 22a, and the virtual money information generation unit 23a each may function as an inference program including learned parameters (coefficients) obtained as a result of learning with a data set.
Each learned model may be provided with additional learning. In other words, each learned model may be provided with a data set different from that of the previous learning and undergo further learning, generating new learned parameters. The learned models incorporated with these new learned parameters may be used.
For the first coin used for an input image for style and the second coin used for a conversion source image, the first coin (money) may be a damaged coin (damaged money) while the second coin (money) may be a new coin (new money). In this case, an image of a virtual coin corresponding to a damaged second coin can be generated even in a situation where a new series second coin is introduced and only new second coins are present.
Conversely, the first coin (money) may be a new coin (new money) and the second coin (money) may be a damaged coin (damaged money). In this case, an image of a virtual coin corresponding to a new second coin can be generated even in a situation where only damaged second coins are present.
The type, i.e., the denomination, of the first coin (money) may be different from the type, i.e., the denomination, of the second coin (money). Even in this case, an image of a virtual coin corresponding to the second coin having a desired damage condition can be generated.
The material of the first coin (money) may be the same as the material of the second coin (money) (including the cases where they are substantially the same as each other). This can make a generated image of a virtual coin look more like a real one. This is because moneys of the same material are damaged in a similar manner even when they are different in type. The materials of the first and second coins may be the coin materials of the surfaces of the respective coins.
Also, banknotes are commonly damaged in different manners depending on their materials. For example, a paper banknote and a polymer sheet banknote (polymer banknote) are soiled in different manners.
The color of the first coin (money) may be similar to the color of the second coin (money). This can also make a generated image of a virtual coin look more like a real one. This is because moneys of similar colors are damaged in a similar way even when they are different in type.
The type, i.e., the denomination, of the first coin (money) may be the same as the type, i.e., the denomination, of the second coin (money). In this case, the damage information generation unit 21a may generate damage information of a first side (e.g., front side) of the first coin (e.g., 10 yen coin) from an image of the first side. The pattern information generation unit 22a may generate, from an image of a second side (e.g., back side), which is different from the first side, among the images of the second coin (e.g., a 10 yen coin different from the first coin), pattern information of the second side. The virtual money information generation unit 23a may generate, from the damage information of the first side generated by the damage information generation unit 21a and the pattern information of the second side generated by the pattern information generation unit 22a, an image of a virtual second side as a fusion of the damage information and the pattern information. This enables generation of an image of a virtual second side that looks more like a real one. This is because moneys of the same type are damaged in a similar manner even on different sides.
The following describes processing applicable to the case where the second coin, in particular a surface thereof, has a plurality of regions formed from different materials. This coin may be a bicolor coin. A specific example thereof may be a new series 500 yen coin to be issued in the first half of fiscal 2021.
In the case where the second coin (e.g., a new series 500 yen coin), in particular a surface thereof, includes a first region (e.g., a ring portion) formed from a first material that is the same as the material (e.g., nickel brass) of the first coin (e.g., a current 500 yen coin), the pattern information generation unit 22a may generate, from an image of the first region of the second coin, pattern information of the first region. The virtual money information generation unit 23a may generate, from the damage information generated by the damage information generation unit 21a and the pattern information of the first region generated by the pattern information generation unit 22a, an image of a virtual first region as a fusion of the damage information and the pattern information. This enables generation of an image of a virtual first region corresponding to the first region (e.g., ring portion) formed from the first material that is the same as the material of the first coin and having a desired damage condition even when the second coin is a bicolor coin.
In the case where the second coin (e.g., a new series 500 yen coin), in particular a surface thereof, includes a second region (e.g., a central portion) formed from a second material that is different from the material of the first coin (e.g., a current 500 yen coin) but is the same as the material (e.g., cupronickel) of a third coin (e.g., an old series 500 yen coin), the damage information generation unit 21a may generate, from an image of the third coin, damage information of the third coin. The pattern information generation unit 22a may generate, from an image of the second region of the second coin, pattern information of the second region. The virtual money information generation unit 23a may generate, from the damage information of the third coin generated by the damage information generation unit 21a and the pattern information of the second region generated by the pattern information generation unit 22a, an image of a virtual second region as a fusion of the damage information and the pattern information. This enables generation of an image of not only the first region (e.g., a ring portion) but also a virtual second region corresponding to the second region (e.g., a central portion) formed from the second material that is the same as the material of the third coin and having a desired damage condition.
In this case, the control unit 20a may be provided with a money information synthesis unit that synthesizes an image of a virtual first region (e.g., a ring portion) and an image of a virtual second region (e.g., a central portion) to generate an image of the whole coin.

With reference to FIG. 2, the following describes the steps of processing executed by the money information generation device 10a.
As shown in FIG. 2, first, the damage information generation unit 21a generates damage information of a first coin from an image (input image for style) of the first coin input to the money information generation device 10a (Step S1).
The pattern information generation unit 22a generates pattern information of a second coin from an image (conversion source image) of the second coin input to the money information generation device 10a (Step S2).
Steps S1 and S2 may be executed in the order of Steps S1 and S2 as shown in FIG. 2, or may be executed in the order of Steps S2 and S1, or may be executed in parallel.
Next, the virtual money information generation unit 23a generates, from the damage information generated in Step S1 and the pattern information generated in Step S2, an image of a virtual coin as a fusion of the damage information and the pattern information (Step S3).
Thereby, the processing is completed.
The aforementioned Steps S1 to S3 may be executed on predetermined samples to generate images of a plurality of virtual coins having different damage conditions and having the same pattern as the second coin.

(Embodiment 2)

First, the outline of a method for generating money information in Embodiment 2 is described. As shown in FIG. 3, in the present embodiment, an input image for style and a conversion source image are first prepared respectively as an image of a first coin and an image of a second coin.
The input image for style (image of the first coin) is an image of the first coin having a desired damage condition, i.e., a damage condition that the coin is desired to have, and has any pattern (design, marking). The input image for style is commonly an image of a coin in circulation having a certain degree of damage (e.g., a damaged coin), but may be an image of a coin without damage (e.g., a new coin).
The conversion source image (image of the second coin) is an image of the second coin that is desired to have the damage condition of the input image for style, and has any damage condition. The conversion source image (image of the second coin) is commonly an image of a coin without damage (e.g., new coin), but may be an image of a coin in circulation having a certain degree of damage (e.g., damaged coin).
Next, the input image for style is used to generate (extract) damage information, which is information relating to damage of the first coin, while the conversion source image is used to generate (extract) pattern information, which is information relating to the pattern of the second coin.
Then, the damage information and the pattern information are used to generate an image of a virtual coin as a fusion of the damage information and the pattern information. This results in generation of an image of a coin (not an actually existing one but a virtual one) having a damage condition at a degree similar to that of the first coin and having the pattern of the second coin. In other words, even when no second coin having a damage condition at a degree similar to that of the first coin is available, template information relating to the second coin can be generated based on the image of a virtual coin generated as described above.
The term "damage information (information relating to damage)" may refer to information relating to the presence of damage or may refer to information relating to the absence of damage. In the former case, the information may be used to deteriorate the marking or base of the coin.
The term "damage condition" is a term indicating the degree of damage and encompasses not only the cases where damage is present but also the cases where damage is absent.
In other words, in the present embodiment, the first coin may be a coin having damage while the second coin may be a coin having no or little damage and the second coin may be damaged, as a virtual coin, to a degree similar to that of the first coin (the damage condition may be worsened). Alternatively, the first coin may be a coin having no or little damage while the second coin may be a coin having damage and the second coin may not be damaged, as a virtual coin, to a degree similar to that of the first coin (the damage condition may be lessened).
For coins, the term "pattern information (information relating to the pattern)" may refer to information relating to the marking of a coin (e.g., 3D information). The term "marking" herein may refer to something that may change when a coin is damaged or may be something that does not change even when a coin is damaged. Specific examples of the pattern information include information relating to a portion where the way the light hits changes in accordance with the degree of damage, information relating to a portion where the edge information changes in accordance with the degree of damage, and information relating to a portion where the material is changed by damage.
In the present embodiment, to make an image of a virtual money look like a real one, machine learning (e.g., deep learning) may be performed using a machine-learning algorithm relating to generation of the damage information, a machine-learning algorithm relating to generation of the pattern information, and a machine-learning algorithm relating to generation of the money information of the virtual money. This can provide a more realistic image of a virtual coin. In other words, an image of a virtual coin generated can be made closer to an image of a real second money having a desired damage condition.
Also, in the present embodiment, an image (image information) may be used as money information to generate an image of a virtual money corresponding to a second money (real one) having a desired damage condition and enables visual check of the quality of the image.

With reference to FIG. 4 and FIG. 5, the following then describes the structure of a money information generation device 10A of the present embodiment. The money information generation device 10A has functions equivalent to a typical personal computer and includes a control unit (processing unit) 20 as shown in FIG. 4 and FIG. 5 and a storage unit (not shown in FIG. 4 and FIG. 5).
As shown in FIG. 4, the control unit 20 has functions of a damage information generation unit 21, a pattern information generation unit 22, a virtual money information generation unit 23, and a learning unit 24 during machine learning, and has functions of the damage information generation unit 21, the pattern information generation unit 22, the virtual money information generation unit 23, and a template generation unit 25 after machine learning (e.g., at practical use).
The control unit 20 includes, for example, software programs for achieving a variety of processing, a CPU that executes the software programs, and a variety of hardware devices controlled by the CPU. The software programs and data for running the control unit 20 are stored in the storage unit.
The units of the control unit 20 shown in FIG. 4 and FIG. 5 are embodied by causing the CPU of the control unit 20 to execute a money information generation program according to the present embodiment. The money information generation program according to the present embodiment may be preinstalled in the money information generation device 10a, or may be provided to a user as an application program that can run on a general-purpose OS, the application program being stored in a computer-readable recording medium or being provided via a network.
The storage unit includes a storage device such as a hard disk device or a non-volatile memory, and stores a learned model that executes processing relating to generation of the damage information, a learned model that executes processing relating to generation of the pattern information, and a learned model that executes processing relating to generation of the money information of a virtual money.
The damage information generation unit 21 generates (extracts), from an image (input image for style) of a first coin input to the money information generation device 10A, damage information relating to damage of the first coin.
The pattern information generation unit 22 generates (extracts), from an image (conversion source image) of a second coin input to the money information generation device 10A, pattern information (pattern characteristics) relating to the pattern of the second coin.
The damage information generated by the damage information generation unit 21 may be information relating to damage of a base of the first coin. In other words, the damage information generation unit 21 may generate (extract) information relating to damage of the base of the first coin from an image (input image for style) of the first coin.
For coins, the term "base" herein commonly refers to the portion excluding the marking of a coin. In other words, a coin commonly includes a base and a marking.
The virtual money information generation unit 23 generates, from the damage information generated by the damage information generation unit 21 and the pattern information generated by the pattern information generation unit 22, an image (image information) of a virtual coin as a fusion (synthesis) of the damage information and the pattern information. This results in generation of an image of a coin (not an actually existing one but a virtual one) having a damage condition at a degree similar to that of the first coin and having the pattern of the second coin.
The damage information generation unit 21, the pattern information generation unit 22, and the virtual money information generation unit 23 are each constructed of a learned model, for example, a learned model utilizing a convolutional neural network (CNN). The CNN of the virtual money information generation unit 23 is coupled with the respective CNNs of the damage information generation unit 21 and the pattern information generation unit 22.
To make an image of a virtual coin generated by the virtual money information generation unit 23 look like a real one, the learning unit 24 provides machine learning of a machine-learning algorithm relating to generation of damage information by the damage information generation unit 21, a machine-learning algorithm relating to generation of pattern information by the pattern information generation unit 22, and a machine-learning algorithm relating to generation of money information of a virtual money by the virtual money information generation unit 23. This machine-learning results in learned models of the damage information generation unit 21, the pattern information generation unit 22, and the virtual money information generation unit 23. Each machine-learning algorithm may utilize a CNN like the aforementioned learned models.
The learning unit 24 also includes a machine-learning algorithm (e.g., one utilizing a CNN) and executes machine learning based on an image of a virtual coin (output image) generated by the virtual money information generation unit 23 and an image of a real coin (training data). In other words, an image of a virtual coin and an image of a real coin are used in learning so as to more accurately determine whether an image of a virtual coin generated by the virtual money information generation unit 23 is a virtual one or a real one (an actually existing one). The learning unit 24 then provides an error between the output from the learning unit 24 and a desired output (correct answer) as a teaching signal to the respective machine-learning algorithms relating to the learning unit 24, the damage information generation unit 21, the pattern information generation unit 22, and the virtual money information generation unit 23, which gradually changes the coupling coefficients of the respective CNNs and finally enables a correct output.
The learned models of the damage information generation unit 21, the pattern information generation unit 22, and the virtual money information generation unit 23 each function as an inference program including learned parameters (coefficients) obtained as a result of learning with a data set.
Each learned model may be provided with additional learning. In other words, each learned model may be provided with a data set different from that of the previous learning and undergo further learning, generating new learned parameters. The learned models incorporated with these new learned parameters may be used.
The template generation unit 25 generates template information from images of a plurality of virtual coins having different damage conditions and having the same pattern as the second coin generated using the machinelearned damage information generation unit 21, pattern information generation unit 22, and virtual money information generation unit 23.
For the first coin used for an input image for style and the second coin used for a conversion source image, the first coin (money) may be a damaged coin (damaged money) while the second coin (money) may be a new coin (new money). In this case, an image of a virtual coin corresponding to a damaged second coin can be generated even in a situation where a new series second coin is introduced and only new second coins are present.
Conversely, the first coin (money) may be a new coin (new money) and the second coin (money) may be a damaged coin (damaged money). In this case, an image of a virtual coin corresponding to a new second coin can be generated even in a situation where only damaged second coins are present.
The type, i.e., the denomination, of the first coin (money) may be different from the type, i.e., the denomination, of the second coin (money). Even in this case, an image of a virtual coin corresponding to the second coin having a desired damage condition can be generated.
The material of the first coin (money) may be the same as the material of the second coin (money) (including the cases where they are substantially the same as each other). This can make a generated image of a virtual coin look more like a real one. This is because moneys of the same material are damaged in a similar manner even when they are different in type. The materials of the first and second coins may refer to the coin materials of the surfaces of the respective coins.
Also, banknotes are commonly damaged in different manners depending on their materials. For example, a paper banknote and a polymer sheet banknote (polymer banknote) are soiled in different manners.
The color of the first coin (money) may be similar to the color of the second coin (money). This can also make a generated image of a virtual coin look more like a real one. This is because moneys of similar colors are damaged in a similar way even when they are different in type.
As shown in FIG. 3, the type, i.e., the denomination, of the first coin (money) may be the same as the type, i.e., the denomination, of the second coin (money). In this case, the damage information generation unit 21 generates damage information of a first side (e.g., front side) of the first coin (e.g., 10 yen coin) from an image of the first side. The pattern information generation unit 22 generates, from an image of a second side (e.g., back side), which is different from the first side, among the images of the second coin (e.g., a 10 yen coin different from the first coin), pattern information of the second side. The virtual money information generation unit 23 generates, from the damage information of the first side generated by the damage information generation unit 21 and the pattern information of the second side generated by the pattern information generation unit 22, an image of a virtual second side as a fusion of the damage information and the pattern information. This enables generation of an image of a virtual second side that looks more like a real one. This is because moneys of the same type are damaged in a similar manner even on different sides.
The following describes processing applicable to the case where the second coin, in particular a surface thereof, has a plurality of regions formed from different materials. This coin may be a bicolor coin. A specific example thereof may be a new series 500 yen coin to be issued in the first half of fiscal 2021.
In the case where the second coin (e.g., a new series 500 yen coin), in particular a surface thereof, includes a first region (e.g., a ring portion) formed from a first material that is the same as the material (e.g., nickel brass) of the first coin (e.g., a current 500 yen coin), the pattern information generation unit 22 generates, from an image of the first region of the second coin, pattern information of the first region. The virtual money information generation unit 23 generates, from the damage information generated by the damage information generation unit 21 and the pattern information of the first region generated by the pattern information generation unit 22, an image of a virtual first region as a fusion of the damage information and the pattern information. This enables generation of an image of a virtual first region corresponding to the first region (e.g., ring portion) formed from the first material that is the same as the material of the first coin and having a desired damage condition even when the second coin is a bicolor coin.
In the case where the second coin (e.g., a new series 500 yen coin), in particular a surface thereof, includes a second region (e.g., a central portion) formed from a second material that is different from the material (e.g., nickel brass) of the first coin (e.g., a current 500 yen coin) but is the same as the material (e.g., cupronickel) of a third coin (e.g., an old series 500 yen coin), the damage information generation unit 21 generates, from an image of the third coin, damage information of the third coin. The pattern information generation unit 22 generates, from an image of the second region of the second coin, pattern information of the second region. The virtual money information generation unit 23 generates, from the damage information of the third coin generated by the damage information generation unit 21 and the pattern information of the second region generated by the pattern information generation unit 22, an image of a virtual second region as a fusion of the damage information and the pattern information. This enables generation of an image of not only the first region (e.g., a ring portion) but also a virtual second region corresponding to the second region (e.g., a central portion) formed from the second material that is the same as the material of the third coin and having a desired damage condition.
In this case, the control unit 20 may be provided with a money information synthesis unit that synthesizes an image of a virtual first region (e.g., a ring portion) and an image of a virtual second region (e.g., a central portion) to generate an image of the whole coin, and the template generation unit 25 may generate template information from an image generated by the money information synthesis unit.

With reference to FIG. 6 and FIG. 7, the following describes the steps of processing executed by the money information generation device 10A.
As shown in FIG. 6, during machine learning, the damage information generation unit 21 first generates damage information of a first coin from an image (input image for style) of the first coin input to the money information generation device 10A (Step S11).
The pattern information generation unit 22 generates pattern information of a second coin from an image (conversion source image) of the second coin input to the money information generation device 10A (Step S12).
Steps S11 and S12 may be executed in the order of Steps S11 and S12 as shown in FIG. 6, or may be executed in the order of Steps S12 and S11, or may be executed in parallel.
Next, the virtual money information generation unit 23 generates, from the damage information generated in Step S11 and the pattern information generated in Step S12, an image of a virtual coin as a fusion of the damage information and the pattern information (Step S13).
Next, the learning unit 24 provides machine learning of the respective machine-learning algorithms relating to the damage information generation unit 21, the pattern information generation unit 22, and the virtual money information generation unit 23. At this time, each machine-learning algorithm relating to the learning unit 24 itself also learns based on the image of the virtual coin generated in Step S13 and the image of the real coin (training data) (Step S14).
The aforementioned Steps S11 to S14 are executed for a predetermined data set, whereby the processing relating to machine learning is completed.
As shown in FIG. 7, after machine learning, the damage information generation unit 21 first generates damage information of a first coin from an image (input image for style) of the first coin input to the money information generation device 10A (Step S21).
The pattern information generation unit 22 generates pattern information of a second coin from an image (conversion source image) of the second coin input to the money information generation device 10A (Step S22).
Steps S21 and S22 may be executed in the order of Steps S21 and S22 as shown in FIG. 7, or may be executed in the order of Steps S22 and S21, or may be executed in parallel.
Next, the virtual money information generation unit 23 generates, from the damage information generated in Step S21 and the pattern information generated in Step S22, an image of a virtual coin as a fusion of the damage information and the pattern information (Step S23).
The aforementioned Steps S21 to S23 are executed on predetermined samples to generate images of a plurality of virtual coins having different damage conditions and having the same pattern as the second coin.
The template generation unit 25 then generates template information from the images of the virtual coins generated (Step S24). Thereby, the processing is completed.

With reference to FIG. 8 to FIG. 10, the following describes the overall structures of a money handling system and money handling device each including the money information generation device of Embodiment 2.

(Embodiment 3)

The present embodiment is substantially the same as Embodiments 1 and 2 except for difference in the method of generating virtual first and second regions in the case where the second coin (in particular, a surface thereof) includes a plurality of regions formed from a plurality of materials. Thus, the contents overlapping those in the above embodiments are not elaborated upon here.
In other words, in the present embodiment, the case mainly considered is such that the second coin (e.g., a new series 500 yen coin), in particular a surface thereof, includes a first region (e.g., a ring portion) formed from a first material that is the same as the material (e.g., nickel brass) of the first coin (e.g., a current 500 yen coin) and a second region (e.g., a central portion) formed from a second material that is different from the material of the first coin but is the same as the material (e.g., cupronickel) of the third coin (e.g., an old series 500 yen coin).
In this case, as described in Embodiments 1 and 2, a virtual image can be generated using images of the first and third coins for each of the first and second regions. Still, the first and second regions are formed from different materials and are therefore unclear whether these regions change over time in the same manner. For example, the manner of soiling of the second region relative to the manner of soiling of the first region is unclear, and vice versa. This makes it difficult to generate a virtual image that takes into consideration the difference in change of damage over time.
Accordingly, in the present embodiment, a plurality of fourth coins (e.g., commemorative coins) is prepared each including a third region (e.g., a ring portion) formed from the first material and a fourth region (e.g., a central portion) formed from the second material. In other words, the third region of the fourth coin is formed from the same material as the first money and the first region of the second money, while the fourth region of the fourth coin is formed from the same material as the third money and the second region of the second money. Then, from each of these images of the fourth coins, the feature of the third region and the feature of the fourth region are calculated and the correlation between the calculated features (e.g., a relational formula indicating the relationship between the calculated features) is created. Based on this correlation, an image of a virtual second coin is generated. This correlation reflects changes of damage over time in the case where the material of the third region, i.e., the first coin, and the material of the fourth region, i.e., the third coin, are present in a single coin. This therefore enables generation of a virtual image that reflects the difference in change of damage over time. The fourth coins may have different damage conditions. The present embodiment is particularly applicable to a situation where the fourth coin is not available in large quantities. Embodiments 1 and 2 are applicable to a situation where no fourth coin is available. The following more specifically describes the present embodiment.

With reference to FIG. 11, the following first describes the structure of a money information generation device 10B of the present embodiment. The structure during machine learning is the same as in Embodiment 2 and therefore the description thereof is not elaborated upon here. As shown in FIG. 11, after machine learning, the control unit 20 of the money information generation device 10B has functions of the damage information generation unit 21, the pattern information generation unit 22, the virtual money information generation unit 23, and the template generation unit 25, as well as functions of a feature calculation unit 26, a combination determination unit 27, and a money information synthesis unit 28. In addition, the storage unit (shown in FIG. 11 with the reference sign 30) of the money information generation device 10B stores a correlation 31, such as a relational formula, created from the features of the third regions and the features of the fourth regions of the fourth coins. The relational formula used may be a subspace, for example.
In the present embodiment, the damage information generation unit 21 generates a plurality of pieces of damage information relating to the first coin from images of a plurality of the first coins (e.g., current 500 yen coins) formed from the same material and having different damage conditions. The damage information generation unit 21 also generates a plurality of pieces of damage information relating to the third coin from images of a plurality of the third coins (e.g., old series 500 yen coins) formed from the same material and having different damage conditions. The third coin is a coin formed from a material different from that of the first coin. The first coins may be of the same type (denomination) or may be of different types (denominations). Similarly, the third coins may be of the same type (denomination) or may be of different types (denominations).
As in Embodiment 2, the pattern information generation unit 22 generates pattern information of the second coin (e.g., a new series 500 yen coin) from an image of the second coin.
The virtual money information generation unit 23 generates, from the pieces of the damage information relating to the first coin and the pattern information, images of a plurality of first virtual coins (the entire coins or only regions corresponding to the first region) each as a fusion of a respective piece of the damage information relating to the first coin and the pattern information. This results in generation of images of a plurality of coins (not actually existing ones but virtual ones) each having a damage condition at a degree similar to that of a respective first coin and having the pattern of the second coin. The virtual money information generation unit 23 also generates, from the pieces of the damage information relating to the third coin and the pattern information, images of a plurality of second virtual coins (the entire coins or only regions corresponding to the second region) each as a fusion of a respective piece of the damage information relating to the third coin and the pattern information. This results in generation of images of a plurality of coins (not actually existing ones but virtual ones) each having a damage condition at a degree similar to that of a respective third coin and having the pattern of the second coin.
The feature calculation unit 26 calculates a first feature of a region corresponding to the first region (e.g., a ring portion) from each of the images of the first virtual coins generated by the virtual money information generation unit 23. The feature calculation unit 26 also calculates a second feature of a region corresponding to the second region (e.g., a central portion) from each of the images of the second virtual coins generated by the virtual money information generation unit 23.
The aforementioned features (the first and second features, the feature of the third region, and the feature of the fourth region) each may be, but are not limited to, the average of the luminances (pixel values), for example. Alternatively, the variance of the luminances (pixel values) or the average and variance of the edge intensities may be used.
The combination determination unit 27 determines optimal combinations of a first feature and a second feature respectively among the first features relating to the first virtual coins and the second features relating to the second virtual coins based on the correlation 31 (e.g., relational formula). For example, a combination having the smallest distance from the relational formula (subspace) may be determined.
The money information synthesis unit 28 synthesizes, from the image of the first virtual coin and the image of the second virtual coin respectively corresponding to the optimal first feature and the optimal second feature determined by the combination determination unit 27, an image of the first virtual coin at a region corresponding to the first region (e.g., an image of a ring portion) and an image of the second virtual coin at a region corresponding to the second region (e.g., an image of a central portion), and generates an image of a third virtual coin containing both images. The money information synthesis unit 28 generates an image of the third virtual coin from an image of the first virtual coin and an image of the second virtual coin for the respective combinations determined by the combination determination unit 27.
The template generation unit 25 then generates template information from the images of the third virtual coins generated by the money information synthesis unit 28.
With reference to FIG. 12, the following describes an example of a more specific processing in the present embodiment. In this example, as shown in FIG. 12, images of a plurality of commemorative coins as fourth coins having different damage conditions are first prepared. These commemorative coins are bicolor coins each including a ring portion formed from the same material as the current 500 yen coin and a central portion formed from the same material as the old series 500 yen coin. The denominations and designs of the commemorative coins are not limited and may be the same as or different from each other. Then, one side of a commemorative coin is separated into four regions (white regions in the figure): the marking portion, the base portion, the central portion (inner), and the ring portion (outer). The correlation 31 is created in the form of a 4-dimensional subspace where the feature is the average of the luminances (pixel values) of the respective regions (learning with the commemorative coins).
Next, images for style of a plurality of current 500 yen coins having different damage conditions and images for style of a plurality of old series 500 yens coins having different damage conditions are prepared and the damage information generation unit 21 generates a plurality of pieces of damage information relating to the current 500 yen coins and a plurality of pieces of damage information relating to the old series 500 yen coins.
Also, a conversion source image of a new series 500 yen coin is prepared and the pattern information generation unit 22 generates pattern information of the new series 500 yen coin.
The virtual money information generation unit 23 then generates images of a plurality of first virtual coins (first output images) each having a damage condition at a degree similar to that of a respective current 500 yen coin and having the pattern of the new series 500 yen coin, and generates images of a plurality of second virtual coins (second output images) each having a damage condition at a degree similar to that of a respective old series 500 yen coin and having the pattern of the new series 500 yen coin.
Then, the feature calculation unit 26 calculates the averages of the luminances (pixel values) for the markings and bases of the ring portions of the images of the first virtual coins and calculates the averages of the luminances (pixel values) of the markings and bases of the central portions of the images of the second virtual coins.
Then, based on the correlation 31, the combination determination unit 27 determines optimal combinations of an image of a first virtual coin and an image of a second virtual coin each having the optimal averages of the luminances. Specifically, between the images of the first virtual coins and the images of the second virtual coins, optimal combinations are determined in each of which the averages of the luminances each have the smallest distance from the 4-dimensional subspace. This results in one-toone correspondences between the images of the first virtual coins and the images of the second virtual coins.
The money information synthesis unit 28 then synthesizes an image of the ring portion of the first virtual coin and an image of the central portion of the second virtual coin of a respective combination to generate an image (inner-outer synthesized image) of a third virtual coin.

With reference to FIG. 13, the following describes the steps of processing executed by the money information generation device 10B. The processing during machine learning is the same as in Embodiment 2 and therefore the description thereof is not elaborated upon here.
In the present embodiment, as shown in FIG. 13, after machine learning, the damage information generation unit 21 first generates, from images (input images for style) of a plurality of the first coins input to the money information generation device 10B, a plurality of pieces of damage information of the first coins, and generates, from images (input images for style) of a plurality of the third coins input to the money information generation device 10B, a plurality of pieces of damage information of the third coins (Step S31).
The pattern information generation unit 22 generates, from an image (conversion source image) of the second coin input to the money information generation device 10B, pattern information of the second coin (Step S32).
Steps S31 and S32 may be executed in the order of Steps S31 and S32 as shown in FIG. 13, or may be executed in the order of Steps S32 and S31, or may be executed in parallel.
Next, the virtual money information generation unit 23 generates, from the pieces of the damage information relating to the first coins generated in Step S31 and the pattern information generated in Step S32, images of a plurality of first virtual coins each as a fusion of a respective piece of the damage information and the pattern information, and generates, from the pieces of the damage information relating to the third coins generated in Step S31 and the pattern information generated in Step S32, images of a plurality of second virtual coins each as a fusion of a respective piece of the damage information and the pattern information (Step S33).
Next, the feature calculation unit 26 calculates a first feature of a region corresponding to the first region (e.g., a ring portion) from each of the images of the first virtual coins generated in Step S33, and calculates a second feature of a region corresponding to the second region (e.g., a central portion) from each of the images of the second virtual coins generated in Step S33 (Step S34).
Next, the combination determination unit 27 determines optimal combinations of a first feature and a second feature based on the correlation 31 (Step S35).
Next, the money information synthesis unit 28 synthesizes, from the image of the first virtual coin and the image of the second virtual coin respectively corresponding to the optimal first feature and the optimal second feature determined in Step S35, an image of the first virtual coin at a region corresponding to the first region and an image of the second virtual coin at a region corresponding to the second region, and generates an image of a third virtual coin (Step S36). This step S36 is executed for each of the combinations determined in Step S35.
The template generation unit 25 then generates template information from the images of the third virtual coins generated in Step S36 (Step S37). Thereby, the processing is completed.
In the present Embodiment, the images of the third virtual coins may be generated by the following processing.
In this case, as in the case shown in FIG. 11, a 4-dimensional subspace is first created as the correlation 31 (learning with the commemorative coins), and a plurality of pieces of damage information relating to the current 500 yen coin and a plurality of pieces of damage information relating to the old series 500 yen coin are generated. Also, the pattern information generation unit 22 generates pattern information of the new series 500 yen coin.
Then, the feature calculation unit 26 calculates the averages of the luminances (pixel values) for the markings and bases of the ring portions of the images of the current 500 yen coins and calculates the averages of the luminances (pixel values) of the markings and bases of the central portions of the images of the old series 500 yen coins.
Next, between the images of the current 500 yen coins and the images of the old series 500 yen coins, the combination determination unit 27 determines combinations in each of which the averages of the luminances each have the smallest distance from the correlation 31 (4-dimensional subspace).
The virtual money information generation unit 23 then generates, from the damage information of the current 500 yen coin and the damage information of the old series 500 yen coin relating to a respective optimal combination and the pattern information of the new series 500 yen coin, an image (output image) of a virtual coin that has a damage condition at a degree similar to that of the current 500 yen coin for the ring portion and a damage condition at a degree similar to that of the old series 500 yen coin for the central portion, and that has the pattern of the new series 500 yen coin.
As described above, in the aforementioned embodiments, the damage information of the first coin is generated from the image of the first coin, the pattern information of the second coin is generated from the image of the second coin, and the image of the virtual coin as a fusion of the damage information and the pattern information is generated from the damage information and the pattern information. Thus, based on the images of the real first and second coins, the image of the virtual coin having a damage condition at a degree similar to that of the first coin and having the pattern of the second coin can be generated. Therefore, even in a situation where no real second coin having a desired damage condition is available, an image of a virtual coin corresponding thereto can be generated.
In the case of a second coin having a plurality of regions formed from a plurality of respective materials, the following method may be used instead of the method described in the aforementioned embodiments. Specifically, a plurality of fourth coins (e.g., commemorative coins) formed from the same materials as the second coin may be used as images (input images for style) of the first coins to directly generate images of virtual coins each having a damage condition at a degree similar to that of a respective fourth coin and having the pattern of the second coin (e.g., a new series 500 yen coin). This method is particularly applicable to the situation where the fourth coin is available in large quantities.
Described in the above embodiments is the case of generating the damage information of the first coin from the image (input image for style) of the first coin. Alternatively, counterfeit information, which is information relating to counterfeit of the first coin, may be generated from the image (input image for style) of the first coin.
Specifically, for example, as shown in FIG. 14, a control unit 20c of a money information generation device 10c has a function of a counterfeit information generation unit 29c instead of the damage information generation unit 21a of Embodiment 1.
The counterfeit information generation unit 29c generates (extracts), from an image (input image for style) of a first money, counterfeit information relating to counterfeit of the first money, specifically a feature relating to counterfeit, for example. In other words, the first money may be a counterfeit money.
In this case, the input image for style (image of the first money) may be an image of the first money having any counterfeit characteristic and may have any pattern (design, marking). The conversion source image (image of a second money) may be an image of the second money to which the counterfeit characteristic of the input image for style is to be given, and may be one having no counterfeit characteristic. In other words, the second money may be not a counterfeit money but a genuine money.
The type, i.e., the denomination, of the first money may be different from the type, i.e., the denomination, of the second money. Even in this case, an image of a virtual money corresponding to the second coin having a desired counterfeit characteristic can be generated.
The virtual money information generation unit 23a generates, from the counterfeit information generated by the counterfeit information generation unit 29c and the pattern information generated by the pattern information generation unit 22a, an image (image information) of a virtual money as a fusion (synthesis) of the counterfeit information and the pattern information. This results in generation of an image of a money (not an actually existing one but a virtual one) having a counterfeit characteristic similar to that of the first money and having the pattern of the second money.
The counterfeit information generation unit 29c may also be constructed of a learned model, for example, a learned model utilizing a CNN. The CNN of the virtual money information generation unit 23c may be coupled with the respective CNNs of the counterfeit information generation unit 29c and the pattern information generation unit 22c.
The learned models of the counterfeit information generation unit 29c, the pattern information generation unit 22a, and the virtual money information generation unit 23a each may function as an inference program including learned parameters (coefficients) obtained as a result of learning with a data set.
Each learned model may be provided with additional learning. In other words, each learned model may be provided with a data set different from that of the previous learning and undergo further learning, generating new learned parameters. The learned models incorporated with these new learned parameters may be used.
With reference to FIG. 15, the following describes the steps of processing executed by the money information generation device 10c.
As shown in FIG. 15, first, the counterfeit information generation unit 29c generates counterfeit information of a first coin from an image (input image for style) of the first coin input to the money information generation device 10c (Step S41).
The pattern information generation unit 22a generates pattern information of a second coin from an image (conversion source image) of the second coin input to the money information generation device 10c (Step S42).
Steps S41 and S42 may be executed in the order of Steps S41 and S42 as shown in FIG. 15, or may be executed in the order of Steps S42 and S41, or may be executed in parallel.
Next, the virtual money information generation unit 23a generates, from the counterfeit information generated in Step S41 and the pattern information generated in Step S42, an image of a virtual coin as a fusion of the counterfeit information and the pattern information (Step S43). Thereby, the processing is completed.
The aforementioned Steps S41 to S43 may be executed on predetermined samples to generate images of a plurality of virtual coins counterfeited by different techniques and having the same pattern as the second coin.
An example of generating counterfeit information may be a money information generation device 10C shown in FIG. 16 and FIG. 17, for example. In this case, during machine learning and after machine learning, the control unit 20 of the money information generation device 10C has a function of a counterfeit information generation unit 29 instead of the damage information generation unit 21 of Embodiment 2.
The counterfeit information generation unit 29 generates (extracts), from an image (input image for style) of a first money, counterfeit information relating to counterfeit of the first money, specifically a feature relating to counterfeit, for example. In other words, the first money is a counterfeit money.
In this case, the input image for style (image of the first money) is an image of the first money having any counterfeit characteristic and may have any pattern (design, marking). The conversion source image (image of a second money) is an image of the second money to which the counterfeit characteristic of the input image for style is to be given, and is one having no counterfeit characteristic. In other words, the second money is not a counterfeit money but a genuine money.
The type, i.e., the denomination, of the first money may be different from the type, i.e., the denomination, of the second money. Even in this case, an image of a virtual money corresponding to the second coin having a desired counterfeit characteristic can be generated.
The virtual money information generation unit 23 generates, from the counterfeit information generated by the counterfeit information generation unit 29 and the pattern information generated by the pattern information generation unit 22, an image (image information) of a virtual money as a fusion (synthesis) of the counterfeit information and the pattern information. This results in generation of an image of a money (not an actually existing one but a virtual one) having a counterfeit characteristic similar to that of the first money and having the pattern of the second money.
The counterfeit information generation unit 29 is also constructed of a learned model, for example, a learned model utilizing a CNN. The CNN of the virtual money information generation unit 23 is coupled with the respective CNNs of the counterfeit information generation unit 29 and the pattern information generation unit 22.
The learned models of the counterfeit information generation unit 29, the pattern information generation unit 22, and the virtual money information generation unit 23 each function as an inference program including learned parameters (coefficients) obtained as a result of learning with a data set.
Each learned model may be provided with additional learning. In other words, each learned model may be provided with a data set different from that of the previous learning and undergo further learning, generating new learned parameters. The learned models incorporated with these new learned parameters may be used.
To make an image of a virtual money generated by the virtual money information generation unit 23 look like an actually existing counterfeit money, the learning unit 24 provides machine learning of a machine-learning algorithm relating to generation of counterfeit information by the counterfeit information generation unit 29, a machine-learning algorithm relating to generation of pattern information by the pattern information generation unit 22, and a machine-learning algorithm relating to generation of money information of a virtual money by the virtual money information generation unit 23. This machine-learning results in learned models of the counterfeit information generation unit 29, the pattern information generation unit 22, and the virtual money information generation unit 23. Each machine-learning algorithm may utilize a CNN like the aforementioned learned models.
The learning unit 24 includes a machine-learning algorithm (e.g., one utilizing a CNN), and executes machine learning based on an image of a virtual money (output image) generated by the virtual money information generation unit 23 and an image of an actually existing counterfeit money (training data). In other words, an image of a virtual coin and an image of a real coin are used in learning so as to more accurately determine whether an image of a virtual money generated by the virtual money information generation unit 23 is a virtual one or an actually existing one. The learning unit 24 then provides an error between the output from the learning unit 24 and a desired output (correct answer) as a teaching signal to the respective machine-learning algorithms relating to the learning unit 24, the counterfeit information generation unit 29, the pattern information generation unit 22, and the virtual money information generation unit 23, which gradually changes the coupling coefficients of the respective CNNs and finally enables a correct output.
