Description

The present invention relates to a measurement system for gaming chips used in amusement arcades.

It has been proposed to attach a radio frequency identification (RFID) tag to each gaming token to keep track of the number and total amount of gaming tokens placed on the gaming table and to keep track of the value of the gaming tokens.

In the card game monitoring system described in Patent Document 1, whether or not gaming tokens placed on a gaming table have been collected or redeemed in accordance with the outcome of a game is determined by image analysis of the movement of the gaming tokens, thereby monitoring for fraudulent activity.
In addition, in gaming establishments such as casinos, it has been proposed to attach an IC tag to each gaming token chip in order to keep track of the number of gaming token chips bet and the total amount.

International Publication No. 2015/107902

Chips as gaming tokens are stacked high and placed on a gaming table, but in the conventional technology where an IC tag is attached to each chip and the stacked chips are read by an IC tag reader installed under the gaming table, there is a problem that the total amount cannot be read accurately because the chips are overlapping, and if the sensitivity of the reader is increased, chips as gaming tokens placed in different positions (where winning or losing depends on the position) are added together, which creates the problem that the total amount of chips as gaming tokens for each position cannot be determined. Also, when capturing images from a camera, there are problems such as blind spots being created due to the camera's viewing angle, or overlapping chips being in the shadows, making it impossible to determine the total amount of chips as gaming tokens.

In gaming establishments such as casinos, chips as gaming tokens are stacked high and placed on gaming tables, but there is a problem in that the IC tag reader installed under the gaming table cannot accurately read the total amount, and if the sensitivity of the reader is increased, chips as gaming tokens placed in different positions (where winning or losing depends on the position) are added together, making it impossible to grasp the total amount of chips as gaming tokens for each position. The present invention aims to provide a new system for measuring the total amount of chips stacked in games at gaming establishments.

In order to solve the above problems, the chip measurement system of the present invention comprises: an image recording device that records, as an image, the state of measurement target chips of a predetermined thickness stacked in a game played on a gaming table using a camera;
A plurality of height measurement cameras for obtaining images of the stacked measurement target chips from different positions or angles;
a chip number measuring device that uses the plurality of height measuring cameras to obtain the height of the chip to be measured from each of the horizontal and vertical viewing angles of the chip to be measured obtained from the plurality of height measuring cameras, and calculates the number of the chips to be measured;
and a management control device that controls the image recording device and the chip number measuring device.

a total chip counting device for calculating the total amount of chips to be counted from the number of chips to be counted obtained from the chip number counting device;
The machine may further include a management control device that controls the total tip measurement device in addition to the image recording device and the chip number measurement device.

The device may further include a total chip counting device that calculates the total amount of the stacked chips to be measured by identifying the type of each chip from the number of chips to be measured obtained from the chip number measuring device and the image analysis results of the image recording device.

The chip measurement system may also be configured such that the management control device is capable of grasping the position, type and number of chips to be measured bet by each player via the image recording device, and grasping the total amount of all chips bet by each player. The chip measurement system may also further include a chip tray camera that obtains an image of the dealer's chip tray at the gaming table, and a chip tray chip measurement device that obtains the total amount of chips on the chip tray from the image from the chip tray camera.

The present invention may be a chip measurement system further comprising a win/loss result determination device that obtains the win/loss results of each game at the gaming table, and the management control device may be configured to be able to ascertain the total amount of chips bet by a losing player in a game from the position, type and number of chips bet by the losing player based on the information obtained from the win/loss result determination device.

Furthermore, the management control device may grasp the total amount of chips to be measured on the dealer's chip tray at the gaming table, add/subtract the increase/decrease in the amount of chips to be measured in the game calculated from the positions, types and numbers of chips to be measured bet by all players in the game and the outcome of the game obtained by the outcome determination device from the total amount of chips to be measured on the chip tray before settlement of each game, compare the total amount of chips to be measured on the chip tray after settlement at the end of the game with the actual total amount of chips to be measured on the chip tray at the end of the game obtained via the image recording device, and determine whether there is a discrepancy between the total amount that should be and the actual total amount.

Furthermore, the chip total measurement device may be a chip measurement system having a plurality of the image recording devices, and the chip total measurement device calculates the total amount of the chips to be measured using images of the stacked chips to be measured taken from different positions or angles of each of the image recording devices.

In addition, the chip to be measured in the chip measurement system is
At least a colored layer and a white or light-colored layer are laminated to form a laminated structure consisting of multiple plastic layers, forming a striped pattern in the stacking direction on the side, and the colored layer is configured to enable the type of game token to be identified, and furthermore, printed layers indicating the type of game token are applied to the top and bottom surfaces of the laminated structure, and the layers are heat-pressed to form a layered structure.

In order to solve the above problems, the chip measurement system of the present invention further comprises:
an image recording device that records, as an image, the state of measurement target chips stacked to a predetermined thickness in a game played on a gaming table using a camera;
A plurality of height measurement cameras for obtaining images of the stacked measurement target chips from different positions or angles;

In gaming facilities such as casinos, chips used as gaming tokens are stacked high and placed on gaming tables, but there is a problem in that the IC tag reader installed under the gaming table cannot accurately read the total amount. If the sensitivity of the reader is increased, the chips used as gaming tokens placed in different positions (where winning or losing depends on the position) will be added together, creating the problem that the total amount of chips used as gaming tokens for each position cannot be determined.

In addition, conventionally, as shown in FIG. 2, the patterns of the chips 120 serving as gaming tokens are complex, and when a large number of gaming token chips are stacked, there is a problem that the camera cannot accurately determine the number of chips stacked.

The chips 120 as gaming tokens may not only be stacked vertically aligned, but may also be stacked offset as shown in FIG. 2. In this case, when the camera device 2 is positioned in the direction of the arrow X shown in FIG. 2 (or when the orientation of the chips 120 as gaming tokens is in a blind spot relative to the camera device 2), it is expected that the chips 120 as gaming tokens will not be visible (will be in a blind spot).

In addition, the dealer needs to collect or redeem the gaming tokens 120 placed on the gaming table in accordance with the winning or losing result. Even if an attempt is made to determine this by image analysis of the gaming tokens 120, the patterns of the gaming tokens 120 are complex, so existing practical image analysis technology cannot determine whether the dealer has accurately redeemed the gaming tokens 120 that correspond to the gaming tokens 120 that were bet, and there is a problem in that mistakes cannot be sufficiently prevented.

According to the system of this embodiment, even if a large number of chips 120 serving as gaming tokens are piled up, the number of chips 120 serving as gaming tokens can be determined by image analysis, and the total amount of chips 120 serving as gaming tokens that are relatively overlapped can be ascertained by their position and color.

The following describes a chip measurement system for table games in an amusement parlor having a gaming table 4 according to an embodiment of the present invention, with reference to the drawings. FIG. 1 is a diagram showing an overview of the system. The system according to this embodiment in an amusement parlor having multiple gaming tables 4 includes a chip total measurement device 302 equipped with an image recording device 300 that records the progress of the game played at the gaming table 4 as images via multiple camera devices 2, including the game participants 6 and the dealer 5, and performs image analysis of the recorded images of the progress of the game, and further includes a card distribution device 3 that determines and displays the results of the win or loss of each game at the gaming table 4. The card distribution device 3 is a so-called electronic shoe that is already used and known by those skilled in the art, and is programmed with the rules of the game in advance, and is structured to read the information (rank and suit) of the cards 1 that are distributed and determine the win or loss of the game. For example, in a baccarat game, the banker's win, the player's win, and a tie (draw) are basically determined by the ranks of two or three cards each, and the determination results (win or loss results) are displayed by an indicator lamp 13.

The management control device 14 reads the information (rank and suit) of the cards 1 obtained from the card distribution device 3 to determine the outcome of each game, and also uses the measurement results of the positions, types, and numbers of chips 120 placed by the game participants 6 as gaming tokens to determine the winners 6W and losers 6L of the participants 6 in each game. It also has a calculation function that performs a calculation of the casino's income and expenditure at the gaming table 4 for each game (the total amount of chips 120 as gaming tokens bet by losers 6L minus the total amount of chips 120 as gaming tokens redeemed to the winners 6W of the participants 6).

The image recording device 300, total tip amount measurement device 302, and management control device 14 in this measurement system are structured to include a computer, program, and memory that are integrated or comprised of multiple components.

Next, the details of the chip as a gaming token used in this measurement will be described. FIG. 3 is a front cross-sectional view of the chip 120 as a gaming token used in this measurement system, which is a multi-layer structure in which a plurality of plastic layers of different colors are laminated, with at least a colored layer 121 in the middle, and a white layer 122 or a light-colored layer (not shown, but it is sufficient that the layer is lighter in color than the colored layer 121) laminated on both sides of this intermediate colored layer 121. By forming a multi-layer structure in which the colored layer 121 is provided and the white layer 122 or a light-colored layer (not shown, but it is sufficient that the layer is lighter in color than the colored layer 121) is laminated on both sides of this intermediate colored layer 121 in this way, a striped pattern is formed in the lamination direction on the side as shown in FIG. 6, and the color of the colored layer 121 is changed (red, green, yellow, blue, etc.) for each type of chip 120 as a gaming token (10 points, 20 points, 100 points, 1000 points, etc.) to enable the type of chip 120 as a gaming token to be identified.

The chip 120 as a gaming token is a structure having a colored layer 121 and a white layer 122 or a light-colored layer at least in appearance so as to form an axial striped pattern on the side, and has a configuration that makes it possible to identify the type of chip 120 as a gaming token by the colored layer 121. Figures 4A and 4B are different embodiments, but are examples in which the colored layer 121 and the white layer 122 or the light-colored layer are formed by injection molding, and are made by so-called two-color molding in which the colored layer 121 is first molded in a molding die (not shown), and then the white layer 122 or the light-colored layer is molded.

Furthermore, as shown in FIG. 5, the chip 120 as a gaming token has a print 123 (such as 100 points) on the surface (upper and lower surfaces) of the white layer 122 indicating the type of chip 120 as a gaming token. As shown in FIG. 3, a transparent layer 124 is provided on the outermost layer, and each layer is thermocompressed to form at least a five-layer structure. These chips 120 as gaming tokens are made of a long, thin plastic material, and each layer (colored layer 121, white layer 122, transparent layer 124) is thermocompressed to form a tightly adhered state (five-layer structure, etc.) while in a long state, and then punched into a circle, rectangle, etc. by a press or the like. When punching out by a press, the dimensions of the die and punch of the metal mold for punching are designed, and R processing (rounded corners) is applied to the edge of the outermost transparent layer 124.

That is, when manufacturing chips 120 as gaming tokens, first, a plate-shaped plastic colored layer 121 and a plate-shaped plastic white layer 122 or light-colored layer are laminated to form a laminated structure consisting of multiple plastic layers. Then, a pattern is printed on the top and bottom surfaces of this laminated structure, and a transparent layer 124 is provided on top of that. Then, each layer of the laminated structure and the transparent layer 124 are heat-pressed to heat-weld each layer to create a token original plate. The token original plate thus produced is punched using a die to obtain multiple chips 120 as gaming tokens of a predetermined shape. During this punching process, the top and bottom outer corners of the chips 120 as gaming tokens are rounded using a die.

Furthermore, the chip 120 as a gaming token has a face code made of UV ink or carbon black ink on the surface of the white layer 122 (see FIG. 5). This face code indicates the authenticity of the chip 120 as a gaming token, and when exposed to ultraviolet (or infrared) light, the mark becomes visible, and the combination of its shape and number indicates authenticity. FIG. 6 is a perspective view of chips 120 as a gaming token stacked up, and the combination of long code FL and short code FS forms face code F. A transparent layer (printed layer) 124 is thermocompressed or coated (applied) on the outermost layer to cover the print 123 and face code, and this transparent layer 124 is embossed to prevent the chips 120 as a gaming token from sticking to each other. In this embodiment, an example has been described in which a face code is printed on the surface of the white layer 122, but instead of or together with the face code, a security mark, an optical variable device (OVD), or both may be printed.

The edges of the outermost transparent layer (printed layer) 124, which is printed with printing 123 (100 points, etc.), are rounded (R) to prevent the surface of the white layer 122 from deforming and appearing on the sides during the process of punching out the chips 120 as gaming tokens. In addition, the chips 120 as gaming tokens are prevented from leaving sharp edges that could cause injury to hands or other chips 120 as gaming tokens.

The colored layer 121 may be formed of multiple colored layers (three layers in FIG. 3) as shown in FIG. 3. The multiple colored layers (three layers in FIG. 3) are thermocompressed together, so the three-layer structure is not visible as in FIG. 3, and FIG. 3 shows three layers for the sake of explanation. Furthermore, a cutout B is provided in the middle layer of the three layers of the colored layer 121, and an RFID 125 is embedded therein.

The RFID 125 may be placed between the flat surface colored layer 121 and the flat surface white layer 122 without providing cutout B in the colored layer 121, and may be embedded in the chip 120 as a gaming token by simply thermocompressing the colored layer 121 and the white layer 122 together. By making at least one of the colored layer 121 and the white layer 122 out of a thermally deformable material such as plastic, the plastic layer of the colored layer 121 and the white layer 122 that sandwich the RFID 125 is thermally deformed by thermocompression, so that the RFID 125 is tightly fixed between these layers even without providing cutout B.

7 is a perspective explanatory photographic diagram illustrating a state where different types of chips 120 as gaming tokens are stacked. In the figure, the management control device 14 uses the camera device 2 to capture images of the chips 120 as gaming tokens placed by the game participants 6 on the gaming table 4, measures the chips by area 8 (whether they were bet on the banker, the player, a pair, or a tie) using the chip total measurement device 302 equipped with the image recording device 300, and analyzes and measures the number and color of the colored layers 121 (or light color layers) or white layers 122 of the chips 120 as gaming tokens stacked in each area (using information obtained by the image recording device 300) to determine the type and number of chips 120 as gaming tokens. The management control device 14 controls the camera device 2 so that it captures images when the first card is drawn from the card dealing device, before or after the first card is drawn, or after the dealer signs the end of betting.

The management control device 14 may be a control device that utilizes artificial intelligence or has a deep learning structure. The management control device 14 is capable of grasping the position 8 (position on whether the player, banker, or pair bet is made), type (different values are assigned to each color of the chips 120 as gaming tokens) and number of chips 120 as gaming tokens bet by each participant 6 via the camera device 2 and the image recording device 300. In an artificial intelligence-based computer or control system, deep learning (structure) technology, it is possible to grasp the position 8 (position where the player, banker, or pair bet is made), type (different values are assigned to each color of chips as gaming tokens) and number of chips 120 as gaming tokens using a self-learning function, etc., so that the management control device 14 analyzes the video of the game progress via the image recording device 300 to determine whether the collection (indicated by arrow E) of the chips 120 as gaming tokens bet by the losing participant 6L of each game and the redemption (payment (120W)) of the winning chips 120 as gaming tokens to the winning game participant 6W were properly performed according to the outcome of the game as determined by the card distribution device 3 in each game.

In such a case, as shown in FIG. 6 (compared to the conventional chips as gaming tokens shown in FIG. 2), a multi-layered structure is formed, and the side has a clearly formed striped pattern in the stacking direction, so that the total chip measurement device 302 including the image recording device 300 can easily and accurately measure the type and number of chips as gaming tokens. Furthermore, the use of an artificial intelligence-based computer or control system and deep learning (structure) technology makes it possible to analyze and judge images more accurately. Since artificial intelligence-based computers or control systems and deep learning (structure) technology are already known and available to those skilled in the art, detailed explanations will be omitted.

The management control device 14 can analyze and grasp the total amount of chips 120 as gaming tokens in the chip tray 17 of the dealer 5 of the gaming table 4 using the image recording device 300, and after the game is over and settled, it can compare and calculate whether the total amount of chips 120 as gaming tokens in the chip tray 17 has increased or decreased according to the outcome of the game, depending on the collection of chips 120 as losing gaming tokens bet by each game participant 6 and the amount of chips 120W paid to the winning game participant 6W as winning gaming tokens. Although the total amount of chips 120 as gaming tokens in the chip tray 17 is always grasped by means such as RFID, the management control device 14 determines whether the increase or decrease is correct by analyzing the video of the game progress state via the image recording device 300. These may also utilize artificial intelligence or deep learning structures.

The management control device 14 may be an artificial intelligence-based or deep learning-based management control device that grasps the position (position where the player, banker, or pair bet) and amount (type and number) of chips as gaming tokens bet at each play position 7 of the gaming table 4, and compares the win/loss history of each game participant 6 obtained by the win/loss result of each game and the amount of chips as gaming tokens obtained (amount won) with statistical data of many past games (big data) to extract it as a unique situation (set by the casino). Typically, the management control device 14 is equipped with an artificial intelligence-based or deep learning-based management control device that can extract it as a unique situation compared with statistical data (big data, etc.) of past games, such as the occurrence of a win of a certain amount (1 million dollars) or a situation in which the amount of chips as gaming tokens for betting when losing is small and the amount of chips as gaming tokens for betting when winning continues for several games.

The management control device 14 is structured to be able to compare and calculate whether the increase or decrease in the amount of chips as gaming tokens corresponding to the settlement is correct after the total amount of chips 120 as gaming tokens in the chip tray 17 of the dealer 5 at the gaming table 4 is settled with the chips 120 as gaming tokens bet by each participant 6 after each game.

In the chip tray 17 for holding chips 120 as gaming tokens at the dealer 5 shown in Figure 1, the total chip amount measuring device 302 (using information obtained by the image recording device 300) analyzes and measures the number and color of the colored layers 121 or white layers 122 of the chips 120 as gaming tokens stacked horizontally, making it possible to determine the type and number of chips 120 as gaming tokens. The total amount of chips 120 as gaming tokens in the holding chip tray 17 is thus constantly (or at predetermined time intervals) known. The management control device 14 has a calculation function (see above) that performs the settlement amount for each game (calculation of the casino's income and expenditure at the gaming table 4 (the total amount of chips 120 as gaming tokens bet by losers 6L minus the total amount of chips 120 as gaming tokens redeemed to winners 6W among participants 6)), so the total amount of chips 120 as gaming tokens in the chip tray 17 is constantly (or at a specified time interval) verified. In other words, it is verified whether the increase or decrease in chips as gaming tokens matches the image analysis results by the image recording device 300 and the settlement amount for each game by the dealer 5.

Figure 8A is a diagram showing details of the chip tray as a gaming token in this embodiment, and Figure 8B is a diagram showing another example of the chip tray as a gaming token. The chip tray 17 is provided with a collection chip tray 171 for collecting and temporarily storing chips 120L as gaming tokens bet by the losing player 6L, and a redemption chip tray 172 for storing chips 120W as gaming tokens to be redeemed. The image recording device 300 and the management control device 14 grasp the position, type and number of chips 120L as gaming tokens bet by the losing player 6L, and calculate the increase in chips 120L as gaming tokens in the game (the amount of chips 120 as gaming tokens that should be in the collection chip tray 171). Furthermore, the image recording device 300 and the management control device 14 grasp the actual total amount of the chips 120 as gaming tokens in the chip tray 171 after collection, and compare the actual total amount with the expected total amount to determine whether there is a difference.

The chip tray 17 shown above has a two-tier structure consisting of an upper chip tray 17a and a lower chip tray 17b. Figures 9A and 9B are diagrams showing the relationship between the two-tier chip tray 17 and the camera device 2, with Figure 9A showing the two tiers stacked and Figure 9B showing the two tiers shifted. The lower chip tray 17b is located below the upper chip tray 17a and they are connected to each other by a hinge 18. When the upper chip tray 17a runs short of chips 120 as gaming tokens, the lower chip tray 17b replenishes the upper chip tray 17a with chips 120 as gaming tokens, and when the upper chip tray 17a runs short of chips 120 as gaming tokens, the lower chip tray 17b replenishes the chips 120 as gaming tokens.

To insert or remove chips 120 as gaming tokens from the lower chip tray 17b, the upper chip tray 17a is moved by the hinge 18 to the state shown in FIG. 9B. In the state shown in FIG. 9A, the upper chip tray 17a is imaged by the camera device 2, and in the state shown in FIG. 9B, the lower chip tray 17b can be imaged by the camera device 2. In the state shown in FIG. 9B, the upper chip tray 17a and the lower chip tray 17b can also be imaged simultaneously and in a state where they can be distinguished from each other by the camera device 2c. Also, in the state shown in FIG. 9B, the upper chip tray 17a and the lower chip tray 17b may be imaged separately.

The management control device 14 can grasp, via the camera device 2 and the image recording device 300, on which position (player, banker, or pair) of the betting area 8 each player 6 has bet the gaming tokens 120, the type of gaming tokens 120 bet (each color of the gaming tokens 120 is assigned a different value) and the number of gaming tokens bet. The gaming tokens 120 may not only be stacked vertically in an aligned manner, but may also be stacked offset from one another as shown in FIG. 2. In this case, when the camera device 2 is positioned in the direction of the arrow X shown in FIG. 2 (or when the gaming tokens 120 are relatively oriented in a blind spot), it is assumed that the gaming tokens 120 will not be visible (will be in a blind spot).

In this way, it is necessary to know which position (player, banker, or pair) of the gaming tokens 120 in the betting area 8 the chips 120 have been bet on, the type of gaming tokens 120 bet (each color of the gaming tokens 120 is assigned a different value) and the number of chips 120.
Then, in accordance with the outcome of each game as determined by the card distribution device 3, the management control device 14 determines whether the collection of chips as losing game tokens bet by each player 6 (as indicated by arrow E) and the payment of chips as winning game tokens to the winning player 6W (120W) were properly carried out in accordance with the outcome of the game by analyzing the video of the game progress via the image recording device 300. If the determination result analyzed by the management control device 14 via the image recording device 300 differs from the reading result by other means (for example, the reading result by RFID), the analysis image can be saved and verified later.

The management control device 14 can analyze and grasp the total amount of chips 120 as gaming tokens in the chip tray 17 of the dealer 5 of the gaming table 4 using the image recording device 300, and after the game is over and settled, can compare and calculate whether the total amount of chips 120 as gaming tokens in the chip tray 17 has increased or decreased according to the outcome of the game, depending on the collection of chips 120 as losing gaming tokens bet by each player 6 and the amount of chips 120W paid to the winning player 6W as winning gaming tokens. Although the total amount of chips 120 as gaming tokens in the chip tray 17 is always grasped by means of RFID or the like, the management control device 14 determines whether the increase or decrease is correct by analyzing the video of the game progress via the image recording device 300.

In this example, fraud or errors are detected based on the outcome of the game, information on how many of what type of gaming tokens 120 were bet and on which position (player, banker, or pair) in the betting area 8, and the increase or decrease in the amount of gaming tokens 120 in the chip tray 17 after the collection of losing gaming tokens and the redemption of winning gaming tokens 120. Therefore, fraud or errors can be detected without knowing the movement of the gaming tokens 120 after the game ends, i.e., whether the gaming tokens 120 that were bet moved to the player's side or the dealer's side.

Here, in the case of baccarat, for example, the outcome of the game can be determined in accordance with the rules of baccarat by reading the rank of the cards 1 dealt in the game with the card dealing device 3. The outcome of the game can also be determined by photographing the gaming table 4 with the camera device 2, analyzing the image with the image recording device 300, and comparing the analysis results with the game rules with the management control device 14. In this case, the camera device 2, the image recording device 300, and the management control device 14 constitute the outcome determination device of the present invention.

Information regarding the player at each playing position 7, the type of gaming token chips 120 bet, and how many chips 120 have been bet at which position in the betting area 8 (player, banker, or pair) can be obtained by photographing the gaming token chips 120 placed in the betting area 8 with the camera device 2 and analyzing the image for each playing position 7 with the image recording device 300. Details will be explained later.

In addition, the increase or decrease in the amount of chips 120 as gaming substitute currency in the chip tray 17 before and after the collection of chips 120 as losing gaming substitute currency and the redemption of chips 120 as winning gaming substitute currency is performed can be calculated by comparing the total amount of chips 120 as gaming substitute currency in the chip tray 17 before the collection of chips 120 as losing gaming substitute currency and the redemption of chips 120 as winning gaming substitute currency with the total amount of chips 120 as gaming substitute currency in the chip tray 17 after the collection of chips 120 as losing gaming substitute currency and the redemption of chips 120 as winning gaming substitute currency. The total amount of the chips 120 as gaming tokens in the chip tray 17 before collecting the chips 120 as losing game tokens and redeeming the chips 120 as winning game tokens, and the total amount of the chips 120 as gaming tokens in the chip tray 17 after collecting the chips 120 as losing game tokens and redeeming the chips 120 as winning game tokens, can be detected by photographing the chip tray 17 containing the chips 120 as gaming tokens with the camera device 2 and analyzing the image with the image recording device 300. Also, the total amount of the chips 120 as gaming tokens contained in the chip tray 17 may be detected by embedding an RFID indicating the amount in the chips 120 as gaming tokens and providing an RFID reader in the chip tray 17.

For example, let us say that the total amount of chips 120 as gaming tokens in the chip tray 17 before the start of the game is Bb, and that the total amount of chips 120 as gaming tokens in the chip tray 17 after the game ends and the collection of chips as losing gaming tokens and the redemption of chips as winning gaming tokens is Ba. Also, let us say that in this game, the total amount of chips 120 as gaming tokens bet on the player area at all play positions 7 is bp, the total amount of chips 120 as gaming tokens bet on the banker area at all play positions 7 is bb, and the total amount of chips 120 as gaming tokens bet on the tie area at all play positions 7 is bt. For example, if the outcome of this game is a win for the banker, Ba-Bb=bp-bb+bt should be established. Alternatively, the total amount Ba of the gaming token chips 120 in the chip tray 17 after the game ends should be (Bb + bp - bb + bt). If this is not the case, it can be determined that there has been fraud or an error in the collection or redemption of the gaming token chips.

As described above, in this embodiment, the management control device 14 calculates the income and expenditure of chips as gaming tokens for each game from the amount of chips as betting gaming tokens on the gaming table 4 and the outcome of the game, and verifies the increase in the balance of chips as gaming tokens in the chip tray 17 after the game. If a difference is detected in this verification, the management control device 14 issues an alarm or adds a record to that effect to the video record captured by the camera device 2. The casino operator can investigate the cause of the difference by checking the video.

The measurement system of this embodiment adds or subtracts the increase or decrease in the amount of chips as gaming tokens in a game, which is calculated from the positions, types, and numbers of chips as gaming tokens bet by all players 6 in that game and the outcome of that game obtained by the outcome determination device, from the total amount of chips 120 as gaming tokens in the chip tray 17 before the settlement of each game, and compares the total amount of chips 120 as gaming tokens in the chip tray 17 after settlement at the end of the game with the actual total amount of chips 120 as gaming tokens in the chip tray 17 at the end of the game obtained via the image recording device 300, and determines whether there is a difference between the actual total amount and the total amount that should be.

The management control device 14 grasps the position, type and number of gaming tokens bet by each player via the image recording device 300, and when all losing gaming tokens bet by each player have been collected, grasps the actual total amount of gaming tokens in the chip tray as gaming tokens, and compares the total amount of gaming tokens 120 in the chip tray 17 that should be, calculated by adding the increase in the chip tray 17 for that game based on the position, type and number of gaming tokens bet by the losing player from the total amount of gaming tokens in the chip tray as gaming tokens before the settlement of each game, with the actual total amount of gaming tokens 120 in the chip tray 17, and determines whether there is a difference between the actual total amount and the total amount.

The management control device 14 compares the total amount of chips 120 as gaming tokens in the chip tray 17 before the settlement of each game, which is calculated by adding the increase in the chip tray 17 for that game based on the position, type, and number of chips 120 as gaming tokens bet by the losing player, with the actual total amount of chips 120 as gaming tokens in the chip tray 17, and determines that there is no difference between the total amount that should be and the actual total amount. If the management control device 14 determines that there is a difference between the total amount that should be and the actual total amount, it determines that there is a payment error and generates a payment error signal to notify the payment error.

The chip tray 17 is provided with a collection chip tray 171 for collecting and temporarily storing chips 120 as gaming tokens bet by losing players, and the image recording device 300 compares the total amount of chips 120 as gaming tokens in the collection chip tray 171 that should be, which is calculated by adding the increase in the amount of chips 120 as gaming tokens in the game calculated from the position, type, and number of chips 120L as gaming tokens bet by the losing player, with the actual total amount of chips 120 as gaming tokens in the collection chip tray 171, and determines whether there is a difference between the total amount that should be and the actual total amount.

When the management control device 14 determines that the actual total amount of chips 120 as gaming tokens grasped in the chip tray 17 of the dealer 5 of the gaming table 4 does not correspond to the increase or decrease in the amount of chips as gaming tokens calculated from the amount of chips bet by all players and the outcome of the game, the image recording device 300 can add an index or time to the captured video, or identify and play back the scene of collection or payment of chips 120 as gaming tokens, so that the image recording device 300 can analyze the record of the game in which the above-mentioned difference occurred.

In this way, the management control device 14 obtains the total amount of chips (chips) as gaming tokens in the chip tray 17 after settlement at the end of the game via the image recording device 300. In this case, the judgment after settlement is made when any of the following 1) to 4) occurs.
1) When the redemption of the winning chips 120 as tokens for gaming is completed,
2) When the card 1 used in the game is collected and discarded in the discard area or discard slot of the table,
3) When a predetermined button associated with the winning/losing result determination device is pressed,
4) When the marker indicating victory or defeat (not shown) is replaced.

In the above measurement system, the management control device 14 takes images of the position, type, and number of chips placed by game players as gaming tokens in each game when it detects any of the following 1) to 3).
1) When the card dealing device detects that the first card is being drawn,
2) Before and after being pulled,
3) After the supervisory control device recognizes the dealer's signal that betting is complete.

The management control device 14 is an artificial intelligence-based or deep learning-based management control device that can grasp the position (position where the player, banker, or pair bet) and amount (type and number) of chips as gaming tokens bet at each play position 7 of the gaming table 4, and can extract the win/loss history of each player 6 obtained by the win/loss result of each game and the amount of chips as gaming tokens obtained (amount won) as a unique situation (set by the casino) by comparing it with statistical data of many past games (big data). Typically, the management control device 14 is equipped with an artificial intelligence-based or deep learning-based management control device that can extract the win/loss history of each player 6 obtained by the win/loss result of each game and the amount of chips as gaming tokens obtained (amount won) as a unique situation (set by the casino) by comparing it with statistical data of many past games (big data, etc.). Typically, the management control device 14 is equipped with an artificial intelligence-based or deep learning-based management control device that can extract the win/loss history of each player 6 obtained by the win/loss result of each game and the amount of chips as gaming tokens obtained (amount won) as a unique situation by comparing it with statistical data of past games (big data, etc.) by comparing it with statistical data of past games (big data, etc.).

Furthermore, the management control device 14 of this measurement system (integrated with the image recording device 300) is structured to be able to identify individual players 6 at playing positions 7 who have been extracted as having anomalous situations or have won a predetermined amount or more. Such player 6 is identified by obtaining an image of the face in the image recording device 300 by extracting feature points or the like, and assigning an identity number (ID, etc.) to the player. When the identified player 6 leaves his/her seat and sits at another gaming table, the management control device 14 has a warning function that notifies the other gaming table of the presence of the specific player. Specifically, the pit manager who manages each gaming table 4 and the person in charge of each table (which may be the dealer) are notified to prevent further anomalous phenomena.

In the above example, the win/loss history and the amount of chips (winning amount) obtained as gaming tokens for each playing position 7 may be monitored without identifying individual players 6. In this case, if a player 6 leaves his/her seat, that player 6 cannot be tracked, but it is possible to detect unusual situations such as a situation in which the amount of chips used as gaming tokens when losing at a specific playing position 7 of one gaming table 4 is small and the amount of chips used as gaming tokens when winning is large for several consecutive games. If such a playing position 7 is detected, there is a suspicion of fraud or a mistake at that playing position 7. Then, by verifying the video recorded at that playing position 7, the fraud or mistake can be discovered.

Specifically, the camera device 2 is installed so as to photograph at least the chips 120 as gaming tokens placed in the betting area 8 of the gaming table 4. The image recording device 300 analyzes the image photographed by the camera device 2 and detects whether the chips as gaming tokens are placed in the player, banker, or tie position of the betting area 8 for each user position 7, and the amount of the placed chips as gaming tokens. The card distribution device 3 also functions as a win/loss result determination device and determines the win/loss result of the game. The management control device 14 records (monitors) the win/loss history for each play position 7 and the amount of chips as gaming tokens (amount of chips acquired as gaming tokens) based on the position (player, banker, or tie) in the betting area 8 where the chips 120 as gaming tokens are placed and the win/loss result of the game. Note that only one of the win/loss history and the amount of chips acquired as gaming tokens may be recorded. If the winning/losing history and/or the history of the amount of chips won as gaming tokens are in a unique situation (set by the casino) compared with the statistical data of many past games (big data), the management control device 14 identifies this player position 7 as a playing position suspected of fraudulent activity.

If cheating is suspected at a certain player position 7, the cheating detection system may generate an alarm (light, sound, or vibration) that is perceptible at least to the dealer at that point in time. This makes it possible to at least halt the game thereafter and prevent the cheating from continuing. In addition, information indicating that cheating is suspected may be added to the video captured and recorded by the camera device 2. This allows the cause of the suspected cheating to be identified by checking the video.

As described above, the chip 120 as a gaming token in this embodiment has a laminated structure made of multiple plastic layers, with the colored layer 121 sandwiched between the white layer 122 or light-colored layer, which forms a striped pattern in the lamination direction on the side. The chip 120 as a gaming token has a configuration in which the type of chip 120 as a gaming token can be identified by the colored layer 121 that appears on the side. In addition, the upper and lower surfaces of the chip 120 as a gaming token are printed. Specifically, the surface of the white layer 122 or light-colored layer is printed, and a transparent layer 124 is provided on the upper surface. The colored layer 121, the white layer 122 or light-colored layer, and the printed layer 124 are heat-pressed between each other to form a layered structure.

The white layer 122 or light-colored layer sandwiching the colored layer 121 may be configured to have different thicknesses above and below. In this embodiment, the outer edges of the upper and lower surfaces of the chip 120 as a gaming token are rounded. This prevents the player's hands from being injured when handling the chip 120 as a gaming token, and prevents damage to other chips 120 as gaming tokens. In this embodiment, the RFID 125 is tightly fixed between the plastic layers that form either the colored layer 121, the white layer 122, or the light-colored layer.

In this embodiment, a face code made of UV-emitting ink or infrared-absorbing ink such as ink that absorbs infrared rays (carbon black ink) is provided on the upper and/or lower surfaces of the chip 120 as a gaming token. As a variation of this embodiment, a security mark, an optical variable device (OVD), or both may be printed on the surface of the chip 120 as a gaming token instead of or in addition to the face code.

In this embodiment, the management control device 14 captures images to determine the position, type, and number of chips placed by game participants in each game as gaming tokens when the first card is drawn from the card distribution device 3, before or after the first card is drawn, or after the dealer signs off to indicate the end of betting.

The measurement system of this embodiment also includes a card distribution device 13 that determines and displays the results of each game at the gaming table 4, a camera device 2 that captures images of chips 120 as gaming tokens placed on the gaming table 4, and a management control device 14 that uses the captured images by the camera device 2 to identify and store the positions, types, and numbers of chips as gaming tokens placed on the gaming table 4 by game participants 6. The chips 120 as gaming tokens are laminated structures in which a colored layer 121 and a white layer 122 or a light-colored layer are laminated, and have stripes on the sides in the stacking direction. The management control device 14 has a calculation function that performs a calculation of the casino's income and expenditure at the gaming table 4 for each game, based on the results of the game obtained from the card distribution device 13 and the positions, types, and numbers of chips 120 as gaming tokens identified using the captured images by the camera device 2.

The management control device 14 has the function of counting the number of colored layers 121, white layers 122, or light-colored layers of the chips 120 as gaming tokens placed by each game participant 6, determining the type and value of the chips as gaming tokens based on the color of the colored layers 121, and determining the number of chips 120 as gaming tokens.

As mentioned above, the chips 120 as gaming tokens may not only be stacked vertically aligned, but may also be stacked offset as shown in FIG. 2. In this case, when the camera device 2 is positioned in the direction of the arrow X shown in FIG. 2 (or when the orientation of the chips 120 as gaming tokens is in a blind spot), it is assumed that the chips 120 as gaming tokens will not be visible (will be in a blind spot). Information on the player at each play position 7, the type of chips 120 as gaming tokens, and how many chips have been bet on which position (player, banker, or pair) in the betting area 8 can be obtained by photographing the chips 120 as gaming tokens placed in the betting area 8 with the camera device 2 and analyzing the images for each play position 7 with the image recording device 300. However, if this is to be done only with the camera device 2, an extremely advanced and expensive image analysis device is required due to problems such as blind spots. This embodiment has a special configuration for solving this problem. Details will be described below.

ここで距離Ｌ、角度α、βは以下の方法によって求められる。交点ＫＲ、ＫＬは、高さ計測用カメラ２Ｒ、２Ｌの画角からみて、最上位の遊技用代用貨幣としてのチップ１２０の中心Ｃを遊技テーブル４上に射影した位置である。従って、高さ計測用カメラ２Ｒ、２Ｌによる撮影画像の最上位の遊技用代用貨幣としてのチップ１２０の輪郭の中心を画像処理によって得ることで交点ＫＲ、ＫＬを得る。さらに、高さ計測用カメラ２Ｒ、２Ｌによる撮影画像を画像処理することによって、遊技用テーブル４を真上から俯瞰する画像を得るなどして、交点ＫＲ、ＫＬ間の距離Ｌ（図１０、１１で示すＬ１、Ｌ２）を得る。さらに、交点ＫＲ、ＫＬの位置が分かれば、高さ計測用カメラ２Ｒ、２Ｌのテーブルからの高さは一定なので、角度α、βを得ることができる。以上より、重なった遊技用代用貨幣としてのチップ１２０の高さＨは、式（１）を変形した式（２）で、上記で得た距離Ｌ及び角度α、βによって得ることができる。

以上では説明を簡単にするために高さ計測用カメラ２Ｒ、２Ｌと遊技用代用貨幣としてのチップ１２０が遊技用テーブル４に垂直な同一平面上にあると仮定したが、高さ計測用カメラ２Ｒ、２Ｌと遊技用代用貨幣としてのチップ１２０が遊技用テーブル４に垂直な同一平面上にない場合でも、図１２において同様に計算することができる。中心Ｃからテーブル面への垂線のテーブル面との交点をＯ、交点Ｏ、ＫＲを結ぶ直線と交点ＫＲ、ＫＬを結ぶ直線のなす角度をγ、交点Ｏ、ＫＬを結ぶ直線と交点ＫＲ、ＫＬを結ぶ直線のなす角度をδとすると、詳細な計算は省略するが、式（２）´で表せる。

以上に示した方法で重なった遊技用代用貨幣としてのチップ１２０の高さＨを得ることで、所定の厚みｔを有する遊技用代用貨幣としてのチップ１２０の枚数はＨ／ｔによって得ることができる。画像記録装置３００は、遊技用代用貨幣としてのチップ１２０の枚数の情報を利用することで、より容易かつ正確にチップの種類とその種類ごとの枚数を得ることができ、チップ総額計測装置３０２は遊技用代用貨幣としてのチップ１２０の総額を得る。同位置にある遊技用代用貨幣としてのチップ１２０に対しては、図１０、１１に示すように、高さＨ１、Ｈ２に対応してＬ１、Ｌ２、角度α、βが変化するため、式（２）によってそれぞれの高さＨ１、Ｈ２を得る。また、高さ計測用カメラ２Ｒ、２Ｌは遊技用代用貨幣としてのチップ１２０を撮影するカメラ装置２の機能を兼ね備えてもよい。 10 and 11, the measurement system of this embodiment further includes height measurement camera devices 2R, 2L that are disposed at a predetermined height from the gaming table 4 and that photograph the chips 120 as gaming tokens from different positions or angles, in addition to the camera device 2 that photographs the chips 120 as gaming tokens in addition to the camera device 2 that photographs the chips 120 as gaming tokens in addition to the camera device 2 that photographs the chips 120 as gaming tokens from different positions or angles. In the following, it is assumed that the height measurement cameras 2R, 2L and the chips 120 as gaming tokens are on the same plane perpendicular to the gaming table 4. The relational equation between the angle α formed by the straight line connecting the height measuring camera 2R and the center C of the chip 120 as the topmost gaming token and the gaming table 4, the angle β formed by the straight line connecting the height measuring camera 2L and the center C of the topmost gaming token 120 and the gaming table 4, the distance L between the intersection KR of the straight line connecting the height measuring camera 2R and the center C of the topmost gaming token 120 and the gaming table 4 and the intersection KL of the straight line connecting the height measuring camera 2L and the center C of the topmost gaming token 120 and the gaming table 4, and the height H of the overlapping chips 120 as gaming tokens is expressed by the following equation.

Here, the distance L and angles α and β are obtained by the following method. The intersection points KR and KL are positions where the center C of the chip 120 as the top gaming token is projected onto the gaming table 4 as seen from the angle of view of the height measuring cameras 2R and 2L. Therefore, the intersection points KR and KL are obtained by obtaining the center of the outline of the chip 120 as the top gaming token in the image captured by the height measuring cameras 2R and 2L by image processing. Furthermore, the image captured by the height measuring cameras 2R and 2L is processed to obtain an image of the gaming table 4 from directly above, and the distance L (L1, L2 shown in Figs. 10 and 11) between the intersection points KR and KL is obtained. Furthermore, if the positions of the intersection points KR and KL are known, the angles α and β can be obtained because the heights of the height measuring cameras 2R and 2L from the table are constant. From the above, the height H of the overlapping chips 120 as gaming tokens can be obtained from the distance L and angles α and β obtained above using equation (2), which is a modification of equation (1).

In the above, for simplicity of explanation, it has been assumed that the height measuring cameras 2R, 2L and the chips 120 serving as gaming tokens are on the same plane perpendicular to the gaming table 4, but even if the height measuring cameras 2R, 2L and the chips 120 serving as gaming tokens are not on the same plane perpendicular to the gaming table 4, the calculation can be performed in the same manner in Fig. 12. If the intersection point between the perpendicular line from the center C to the table surface and the table surface is O, the angle between the line connecting the intersection points O and KR and the line connecting the intersection points KR and KL is γ, and the angle between the line connecting the intersection points O and KL and the line connecting the intersection points KR and KL is δ, then it can be expressed by equation (2)', although detailed calculations will be omitted.

By obtaining the height H of the stacked chips 120 as gaming tokens using the method described above, the number of chips 120 as gaming tokens having a predetermined thickness t can be obtained by H/t. The image recording device 300 can obtain the types of chips and the number of each type more easily and accurately by using the information on the number of chips 120 as gaming tokens, and the total chip measurement device 302 obtains the total amount of chips 120 as gaming tokens. For chips 120 as gaming tokens at the same position, L1, L2, angles α, β change according to the heights H1, H2 as shown in Figures 10 and 11, so that the respective heights H1, H2 are obtained by formula (2). In addition, the height measurement cameras 2R, 2L may also function as a camera device 2 for photographing the chips 120 as gaming tokens.

Figure 13 is a diagram of the measurement system of this embodiment for roulette. Chips 220 as gaming tokens are stacked and placed on the gaming table 201. In this case, too, the height measurement cameras 2R and 2L can obtain the distance L between the intersection KR of the straight line connecting the height measurement camera 2R and the center C of the top gaming token 220 with the gaming table 201 and the intersection KL of the straight line connecting the height measurement camera 2L and the center C of the top gaming token 220 with the gaming table 201, using the method described above, and the height H of the chips 220 as gaming tokens can be obtained. The number of chips 220 as gaming tokens can be obtained from the height H and the thickness t of the chips 220 as gaming tokens. In roulette, one type of chip 220 as gaming tokens with different colors is used for each player. Therefore, the total amount of gaming tokens 220 can be obtained simply from the number of gaming tokens 220 obtained by the height measuring cameras 2R and 2L and the chip count measuring device 301, and the player 6 who placed the bet can be identified from the color of the top gaming token chip 220.

In the measurement system of this embodiment, the management control device 14 may have an artificial intelligence or deep learning structure, but artificial intelligence or deep learning structures are described in U.S. Patent No. 9,361,577, U.S. Patent Publication No. 2016-171336, U.S. Patent Publication No. 2015-036920, Japanese Patent Publication No. 2016-110232, etc., and these descriptions are incorporated herein by reference.

Although various embodiments of the present invention have been described above, the above-mentioned embodiments can of course be modified by those skilled in the art within the scope of the present invention, and the device of the present embodiments may be appropriately modified according to the needs of the game to which it is applied.
