[0002] This application is a divisional application of the patent filed on August 2, 2016, with patent application number 201680045982.3, entitled "Cheating Detection System for Amusement Parks".

[0003] Reference to Related Applications

[0004] This application claims the rights of patent application number 2015-163213 filed in Japan on August 3, 2015, and patent application number 2015-206735 filed in Japan on October 1, 2015, the contents of which are incorporated herein by reference. Technical Field

[0005] The present invention relates to a system for detecting cheating in games at amusement parks, or errors and cheating in the placement and calculation of game coins. Background Art

[0006] In amusement parks and other entertainment venues, efforts are being made to prevent various forms of cheating. Amusement parks are equipped with surveillance cameras to monitor cheating behavior. Based on images obtained from the surveillance cameras, cheating in games, such as the recovery or redemption of game coins that differ from the winning or losing outcome, is determined, thus preventing cheating.

[0007] On the other hand, in order to monitor the number and total amount of game coins placed, a scheme has been proposed to attach wireless IC (RFID) tags to each game coin to monitor the amount of game coins.

[0008] In the card game monitoring system described in International Publication No. 2015 / 107902, image analysis of changes in game coins is used to determine whether game coins placed on the game table are recovered or redeemed according to the winning or losing outcome, thereby monitoring cheating behavior.Summary of the Invention

[0009] Problem to be Solved by the Invention

[0010] The purpose of this invention is to provide a new system that detects cheating behavior in games at amusement parks, or errors and cheating behavior in the placement and calculation of game coins.

[0011] Solution to the Problem

[0012] One aspect of the present invention is a cheating detection system for an amusement park with multiple game tables, comprising: a game recording device that records the state of a game played at the game table as an image using a camera; an image analysis device that performs image analysis on the recorded game state image; a win / loss result determination device that determines the win / loss result of each game at the game table; and a control device that uses the image analysis result of the image analysis device and the win / loss result determined by the win / loss result determination device to detect cheating behavior at the game table; the control device, by means of the image analysis device, grasps the position, type, and number of game coins placed by each player, and also grasps the total amount of game coins in the game coin tray of the dealer at the game table, and adds or subtracts the game coins in the game calculated based on the position, type, and number of game coins placed by all players in the game and the win / loss result obtained by the win / loss result determination device from the total amount of game coins in the game coin tray before the settlement of each game. 121121919 A ​​Reduction: The total amount of game coins in the game coin tray after the game ends is compared with the actual total amount of game coins in the game coin tray at the end of the game obtained by the image analysis device, and it is determined whether there is a difference between the total amount and the actual total amount.

[0013] Alternatively, in the above-mentioned cheating detection system, the control device can use the image analysis device to grasp the position, type and number of game coins placed by each player. When all the lost game coins placed by each player are collected, the actual total amount of game coins in the game coin tray is grasped. The total amount of game coins in the game coin tray before the game ends is added to the total amount of game coins in the game coin tray according to the position, type and number of game coins placed by the losing player. The total amount of game coins in the game coin tray is then compared with the actual total amount of game coins in the game coin tray to determine whether there is a difference between the total amount and the actual total amount.

[0014] Alternatively, in the above-mentioned cheating detection system, the control device may compare the total amount of game coins in the game coin tray before each game settlement with the actual total amount of game coins in the game coin tray. This comparison is made by adding the game coin tray's allowance to the total amount of game coins in the tray based on the position, type, and number of game coins placed by the losing player. If there is no difference between the expected total amount and the actual total amount, the control device may also compare the expected total amount of game coins in the game coin tray after the game ends with the actual total amount of game coins in the game coin tray at the end of the game, obtained through the image analysis device. If there is a difference between the expected total amount and the actual total amount, a payment error is determined, and a payment error signal is generated to notify the payment error.

[0015] Alternatively, in the above-mentioned cheating detection system, a game coin tray can be provided in the game coin tray to collect and temporarily store the game coins placed by the losing player. The image analysis device and the control device compare the expected amount of game coins in the game coin tray calculated based on the position, type, and number of game coins placed by the losing player with the actual total amount of game coins in the game coin tray, and determine whether there is a difference between the expected total amount and the actual total amount in the game coin tray.

[0016] Alternatively, in the above-mentioned cheating detection system, the actual total amount of game coins in the game coin tray after the game ends can be obtained by the image analysis device at any of the following times:

[0017] 1) When the repayment of won game coins ends;

[0018] 2) When the cards used in the game are collected and discarded in the discard area of ​​the table;

[0019] 3) When the prescribed button attached to the win / loss result determination device is pressed;

[0020] 4) When the sign indicating win / loss is restored.

[0021] In the above-described cheating detection system, in order to analyze the game recorder's record of the game that caused the discrepancy when the control device determines that the actual total amount of game coins held in the dealer's coin tray at the game table does not correspond to the increase or decrease of game coins calculated based on the total amount of game coins placed by all players and the winning or losing result of the game, the game recorder is configured to assign an index or time to the acquired image, or to determine and reproduce the scene of game coin collection or payment.

[0022] In the above-described cheating detection system, the image analysis device or control device is configured to obtain information on the type, number, and position of the placed game coins even when multiple game coins placed on the game table are partially or entirely hidden due to the blind spot of the camera.

[0023] Alternatively, in the above-mentioned cheating detection system, the control device may be configured to perform the following actions:

[0024] 1) Grasp the position, type, and number of game coins placed at each playing position on the game table, compare the historical win / loss records of each player and the amount of game coins obtained from the win / loss results of each game with the statistical data of past games, and extract it as an abnormal situation, or as per the specification 2 / 19 page 5 CN 121121919 A ​​

[0025] 2) Compare the state where the amount of game coins placed when losing at the playing position on the game table is less than the amount of game coins placed when winning with the statistical data of past games, and extract it as an abnormal situation.

[0026] Alternatively, in the above-mentioned cheating detection system, the control device may be able to compare and determine whether the amount of game coins held in the game coin tray of the dealer at the game table has been reduced after purchasing game coins with paper money, based on the payment amount of game coins corresponding to the paper money used for purchase, or the payment amount of paper money corresponding to the purchased game coins.

[0027] Alternatively, in the above-mentioned cheating detection system, the control device may also have a database containing purchase history records of game coins purchased with paper money. It can compare and determine, at certain intervals or on a daily basis, the amount of game coins held in the dealer's game coin tray at the game table, whether a deduction has been made based on the payment amount of game coins corresponding to the paper money used for purchase, or the total payment amount of paper money corresponding to the purchased game coins.

[0028] Alternatively, in the above-mentioned cheating detection system, the control device can determine the player whose playing position is extracted as a result of the difference or abnormal situation using the image analysis device.

[0029] Alternatively, in the above-mentioned cheating detection system, the control device may have a warning function that notifies the other game table of the presence of the specific player when the determined player leaves their seat and sits at another game table.

[0030] In the above-mentioned cheating detection system, the control device may also have the function of determining at least one of the following:

[0031] 1) In each game, whether there is any change in game coins from the time the starting card is drawn or from the time the dealer starts the game until the game result is displayed by the card issuing device;

[0032] 2) After each game ends, during the period when the dealer collects the game coins placed by the losers among the game participants, whether the losers do not take the game coins;

[0033] 3) After each game ends, during the period when the dealer collects the game coins placed by the losers among the game participants, whether additional game coins are added;

[0034] 4) After each game ends, whether the dealer pays the game coins placed by the winners among the game participants;

[0035] 5) After each game ends, whether the winners among the game participants take the placed game coins and the paid game coins.

[0036] In the above-mentioned cheating detection system, the win / loss result determination device may be a card dispensing device that dispenses cards at the game table, or a control device that determines the win / loss result of each game based on information from the image analysis device that reads the cards dispensed at the game table using a camera.

[0037] Effects of the Invention

[0038] According to the cheating detection system of the present invention, cheating in the recycling and repayment of game coins based on the win / loss result of the game can be detected.

[0039] Moreover, according to the system of the present invention, even if a card is bent due to repeated squeezing of the card by a player in a card game, the card size and suit can be determined by image analysis, and the total amount and position of game coins in blind spots and overlapping areas can also be grasped. Cheating when purchasing game coins with paper money can also be detected. Brief Description of the Drawings

[0068] (First Embodiment)

[0069] In amusement parks such as casinos, game coins are piled high on game tables. However, for IC tag reading devices placed under the game tables, there is a problem that the total amount cannot be accurately read. If the sensitivity of the reading device is increased, there is a problem that game coins placed in different positions (by the left and right of the position) are totaled, and it is impossible to grasp the total amount of game coins in each position. Moreover, for the shooting from the camera, there is a problem that blind spots are formed due to the camera's angle, or that the image is blocked due to overlap, so it is impossible to grasp the total amount of game coins.

[0070] Moreover, although this is often done in a certain card game, there is a problem that: due to the player's squeezing of the card (bending the card face down, looking at the card face size little by little while waiting), the card is bent, and the card face size and suit cannot be determined by the image analysis from the camera.

[0071] Moreover, a new problem arises: the sophistication of cheating at game tables. Cheating based on advanced placement methods, which cannot be detected simply by checking for higher winning amounts, cannot be detected by cameras or by tracking winning amounts. Furthermore, cheating based on collusion between the dealer and the player cannot be adequately prevented using existing technology.

[0072] To solve the above-mentioned problems, the cheating detection system for an amusement park with multiple game tables according to the first embodiment,

[0073] is a cheating detection system for an amusement park with multiple game tables, comprising:

[0074] a game recording device that records the progress of a game played at the game table, including the dealer and players, as an image using a camera;

[0075] an image analysis device that performs image analysis on the recorded game progress image;

[0076] a card dispensing device that determines and displays the win / loss results of each game at the game table; and

[0077] a control device that uses the image analysis results of the image analysis device and the win / loss results determined by the card dispensing device to detect cheating behavior at the game table.

[0078] In addition, in the cheating detection system, the card dispensing device is configured to read the card size of the dispensed cards, and the control device is configured to compare the card size information obtained by the image analysis device from the image of each card dispensed at the game table with the card size information read by the card dispensing device to determine whether they are consistent or not.

[0079] In addition, in the cheating detection system, the image analysis device or control device is an artificial intelligence-efficient or deep learning-based structure that can obtain card size information from cards dispensed at the game table that have been bent or soiled by the player.

[0080] In addition, in the cheating detection system, the control device uses the image analysis device to grasp the position, type, and number of game coins placed by each player, and analyzes the image of the game's progress using the image analysis device to determine whether the lost game coins placed by each player have been correctly collected and the won game coins have been correctly paid out according to the game's winning and losing results.

[0081] Furthermore, in the cheating detection system, the image analysis device or control device is an AI-efficient or deep learning-based structure that can obtain information about the type, number, and location of the placed game coins even when multiple game coins placed on the game table are partially or entirely hidden due to the blind spot of the camera.

[0082] Furthermore, in the cheating detection system, the control device is an AI-efficient or deep learning-based structure that can compare and calculate the amount of game coins held in the dealer's game coin tray according to the game's winning or losing results, and after the game ends and is settled, adjust whether to recover the lost game coins placed by each player and increase or decrease the payout amount for the won game coins.

[0083] Furthermore, in the cheating detection system, the control device is an AI-efficient or deep learning construct capable of grasping the position and amount of game coins placed at each playing position of the game table, comparing the historical win / loss records of each player and the amount of game coins obtained from the win / loss results of each game with the statistical data of past games, and extracting anomalies.

[0084] Furthermore, in the cheating detection system, the control device is an AI-efficient or deep learning construct capable of comparing the state where the amount of game coins placed at a certain playing position of the game table when losing is less than the amount of game coins placed when winning with the statistical data of past games, and extracting anomalies.

[0085] Furthermore, in the cheating detection system, the control device is a construct capable of identifying individual players at playing positions where anomalies are extracted by means of the image analysis device, or where a player has won by a predetermined amount or more.

[0086] Furthermore, in the cheating detection system, the control device has a warning function that notifies the other game table of the presence of the specific player when the identified player leaves and sits at another game table.

[0087] To solve the above-mentioned problems, the cheating detection system for an amusement park with multiple game tables according to this application comprises:

[0088] a game recording device, which records the progress of a game at the game table, including the dealer and players, as an image using a camera;

[0089] a card dispensing device, which determines and displays the winning or losing results of each game at the game table;

[0090] an image analysis device, which performs image analysis on the recorded game progress images; and

[0091] a control device, which can use the image analysis results of the image analysis device to detect banknotes and game coins at the game table;

[0092] The image analysis device or control device is constructed using artificial intelligence or deep learning in the following way: based on information obtained from the card dispensing device or the dealer, in situations other than card distribution, it can detect that game coins are being purchased with paper money at the game table, and recognize the total amount of the paper money verified by near-ultraviolet light. Even if multiple game coins taken from the game table as purchases are partially or entirely hidden due to the blind spot of the camera, it can still recognize the total amount of game coins. It can compare the total amount of paper money taken from the game table by the player with the total amount of game coins taken from the dealer to determine whether the two amounts are consistent.

[0093] In addition, in the cheating detection system, the control device is constructed using artificial intelligence or deep learning in the way that compares and calculates the amount of game coins held in the dealer's game coin tray at the game table, and whether a deduction is made based on the payment amount of game coins corresponding to the paper money used for purchase after the purchase and settlement.

[0094] Furthermore, in the cheating detection system, the control device is constructed using artificial intelligence or deep learning in the following way: it can compare and calculate the consistency between the amount of money received based on the dealer's input and the total amount of money received based on the image analysis result of the image analysis device after purchasing game coins with paper money and clearing the account. Moreover, the control device is constructed using artificial intelligence or deep learning in the following way: it can compare and calculate the consistency between the total amount of money received based on the dealer's input at the game table managed by the dealer and the total amount of money received based on the image analysis result of the image analysis device.

[0095] According to the cheating detection system of this embodiment, even if the cards are bent due to repeated squeezing of the cards by players in a card game, the size and suit of the cards can be determined through image analysis, and the total amount and position of game coins in blind spots and overlapping areas can also be grasped. Furthermore, it can also detect cheating when purchasing game tokens with paper money.

[0096] Hereinafter, the overall outline of the cheating detection system in an amusement park with multiple game tables according to the first embodiment of the present invention will be described in further detail. FIG1 is a diagram showing the overall outline of the same system. The cheating detection system in an amusement park with multiple game tables 4 includes: a game recording device 11, which records the progress of the game played at the game table 4, including the player 6 and the dealer 5, as images through multiple cameras 2; an image analysis device 12, which performs image analysis on the recorded images of the game progress; and a card dispensing device 3, which determines and displays the winning or losing result of each game at the game table 4. The card dispensing device 3 is a so-called electronic shoe used by those skilled in the art, which is configured to pre-program the rules of the game, read the information of the card C that is dispensed, and determine the winning or losing result of the game. For example, in a certain card game, the outcome of a win for player B, a win for player P, or a draw is basically determined by the size of 2-3 cards. The result (win or loss result) is displayed by the result display light 13.

[0097] This cheating detection system also has a control device 14, which compares the actual card size based on the image analysis result of the image analysis device 12 with the win or loss result determined by the card distribution device 3, and detects cheating behavior (such as inconsistency between the total card size and the win or loss result) performed at the game table 4.The card dispensing device 3 is configured to read the face value (A, 2-10, J, Q, K) and suit (hearts, spades, etc.) of the cards C manually dispensed by the dealer 5. The control device 14 is configured to compare the face value and suit information obtained by the image analysis device 12 (using artificial intelligence) from the images of each card dispensed at the game table 4 (captured by the camera 2) with the card and suit information read by the card dispensing device 3, and determine whether they match. The image analysis device 12 and the control device 14 in this cheating detection system are configured as a single unit or composite, comprising a computer, program, and memory.

[0098] The image analysis device 12 and the control device 14 are configured to effectively utilize artificial intelligence or deep learning to obtain the face value information of cards C even if they are dispensed at the game table 4 and bent or soiled by the player 6. As shown in Figure 4, soiled cards C are difficult to distinguish as clubs or spades. Even in such cases, the identification of suits becomes possible through the analysis and judgment of images using AI-efficient computer or control systems and deep learning (construction) technology. Furthermore, even if a card is bent due to repeated squeezing by players in a card game, the suit and face value of the card before deformation can be identified through self-learning from multiple image deformation examples, using AI-efficient computer or control systems and deep learning (construction) technology. AI-efficient computer or control systems and deep learning (construction) technology are well-known and usable by those skilled in the art, so detailed descriptions are omitted.

[0099] Specifically, the AI-efficient or deep learning-constructed control device 14 can, through the camera 2 and image analysis device 12, determine the position (P, B, or PAIR) where each player 6 places the game coins 9 in the placement area 8, the type of game coins 9 (game coins 9 are assigned different values ​​according to each color), and the number of coins. The game coins 9 may overlap vertically or be staggered as shown in Figure 2A. In this situation, as shown by arrow X in Figure 2A (or when coin 9 is facing a blind spot), as in Figure 2B, it can be imagined that coin 9 is not visible (it has entered a blind spot). Artificial intelligence-enabled computer or control systems, and deep learning (construction) technology, can use self-learning functions to identify instances of coin 9 being hidden due to blind spots (whether a single coin is partially hidden or the entire coin is hidden), and accurately determine the number of coins. (This is described in the camera's instruction manual, page 7 / 19, 10 CN 121121919 A).Thus, since it is possible to determine the location (P, B, or PAIR) of the game coin 9 in the placement area 8, the type of game coin 9 (game coins 9 are assigned different values ​​according to each color), and the number of coins, in each game, according to the winning or losing result determined by the card dealing device 3, the control device 14 analyzes the image of the game's progress using the image analysis device 12 to determine whether the game coins lost by each player 6 have been correctly recovered (indicated by arrow L) and the winning game coins (9W) have been paid to the winning player 6W.

[0100] The control device 14 can use the image analysis device 12 to analyze and grasp the total amount of game coins 9 in the game coin tray 17 of the dealer 5 at the game table 4. After the game ends and is settled, it can compare and calculate whether the total amount of game coins 9 in the game coin tray 17 corresponds to the amount of the recovery of lost game coins 9 placed by each player 6 and the payment of the winning game coins (9W) to the winning player 6W, and adjust the total amount of game coins 9 in the game coin tray 17 accordingly. Even though the total amount of game coins 9 in the game coin tray 17 is monitored by means of RFID, the control device 14 determines whether the increase or decrease is correct by analyzing the image of the game's progress using the image analysis device 12. This also effectively utilizes artificial intelligence or deep learning structures.

[0101] In this example, since cheating or errors are detected based on the game's winning or losing results, the information of which type of game coin 9 is placed in which position (P, B, or PAIR) of the placement area 8, and the increase or decrease of game coins 9 in the game coin tray 17 after the recovery of lost game coins and the repayment of won game coins 9, cheating or errors can be detected even without monitoring the changes of game coins 9 after the game ends, i.e., whether the placed game coins 9 are moved to the player's side or to the dealer's side.

[0102] Here, for example, in the case of a certain card game, the winning or losing result of the game can be determined according to the rules of a certain card game by reading the face value of the cards C that are successively dealt by the card dispensing device 3 in the game. Furthermore, by using camera 2 to capture images of the game table 4, analyzing these images using image analysis device 12, and comparing the analysis results with the game rules using control device 14, the outcome of the game can be determined. In this case, camera 2, image analysis device 12, and control device 14 constitute the outcome determination device. Information regarding which type of game coin 9 each player in each play position 7 placed, how many of them, and in which position (P, B, or PAIR) of the placement area 8 can be obtained by camera 2 capturing images of the game coins 9 placed in the placement area 8, and by image analysis device 12 analyzing these images for each play position 7.

[0103] Furthermore, the increase or decrease in the amount of game coins 9 in the game coin tray 17 before and after the recycling of lost game coins 9 and the repayment of won game coins 9 can be calculated by comparing the total amount of game coins 9 in the game coin tray 17 before the recycling of lost game coins 9 and the repayment of won game coins 9 with the total amount of game coins 9 in the game coin tray 17 after the recycling of lost game coins 9 and the repayment of won game coins 9. The total amount of game coins 9 in the game coin tray 17 before the recycling of lost game coins 9 and the repayment of won game coins 9, and the total amount of game coins 9 in the game coin tray 17 after the recycling of lost game coins 9 and the repayment of won game coins 9 can be detected by the image analysis device 12 analyzing the images taken by the camera 2 of the game coin tray 17 containing game coins 9. Alternatively, the total amount of game coins 9 stored in the game coin tray 17 can be detected by embedding an RFID tag indicating its value within the game coin 9 and by installing an RFID reader on the game coin tray 17.

[0104] For example, let the total amount of game coins 9 in the game coin tray 17 before the game starts be Bb, and the total amount of game coins 9 in the game coin tray 17 after the game ends, including the recovery of lost game coins and the repayment of won game coins, be Ba. Furthermore, in this game, the total amount of all play positions 7 of game coins 9 placed in area P is bp, the total amount of all play positions 7 of game coins 9 placed in area B is bb, and the total amount of all play positions 7 of game coins 9 placed in the tie area is bt. For example, if the game results in B winning, Ba - Bb = bp - bb + bt should hold. Alternatively, the total amount Ba of game coins 9 in the game coin tray 17 after the game ends should be (Bb + bp - bb + bt). In cases where this is not the case, it can be determined that cheating or errors exist in the recycling or repayment of game coins.

[0105] FIG3A is a diagram showing a detailed view of the game coin tray of this embodiment, and FIG3B is a diagram showing another example of the game coin tray. The game coin tray 17 is provided with a recycling game coin tray 171 and a repayment game coin tray 172. The recycling game coin tray 171 recycles and temporarily stores the game coins 9L placed by the losing player 6L, and the repayment game coin tray 172 stores the game coins 9W to be repaid. The image analysis device 12 and the control device 14 grasp the position, type and number of game coins 9L placed by the losing player 6L, and calculate the additional portion of game coins 0L in the game (the due amount of game coins 9L in the recycling game coin tray 171).Furthermore, the image analysis device 12 and the control device 14 grasp the actual total amount of game coins 9 in the recycled game coin tray 171, and compare the total amount with the actual total amount to determine whether there is a difference.

[0106] In addition, by using the game coin tray 172 to repay the 60,000 game coins 90,000 to the winning player, sufficient time can be ensured for the image analysis device 12 and the control device 14 to grasp the actual total amount of game coins 9 in the recycled game coin tray 171.

[0107] The game table 4 has a discard area 41 and / or a discard slit 42 for discarding cards C used in the game. At the end of each game, the cards C used in the game are recycled and placed in the discard area 41 or the discard slit 42 on the game table 4 for discarding.

[0108] The game table 4 also has a sign 43 indicating the win or loss of the game. FIG5A is a top view showing the front of the sign, and FIG5B is a top view showing the back of the sign. In a certain card game, two symbols are used: 43a, indicating that player P wins, and 43b, indicating that player B wins. When the game results are announced, the dealer 5 flips over the winning symbol of either player P or player B. This makes the outcome of the game easily and clearly displayed on the table. The flipped symbols are restored by the dealer 5 after the game coins 9 are collected and repaid. Restoring the symbols also means that the game can begin.

[0109] As described above, in this embodiment, the control device 14 calculates the income and expenditure of game coins for each game based on the amount of game coins placed on the game table 4 and the outcome of the game, and verifies the increase in the balance of game coins in the game coin tray 17 after the game. If the control device 14 detects a discrepancy in this verification, it issues an alarm or adds a record indicating the situation to the video recording captured by the camera 2. The casino operator can investigate the cause of the discrepancy by reviewing the video.

[0110] In the cheating detection system of this embodiment, the total amount of game coins 9 in the game coin tray 17 before the game is cleared is added to and subtracted from the increase or decrease of game coins in the game calculated based on the position, type and number of game coins 9 placed by all players 6 in the game and the win or loss result of the game obtained by the win or loss result determination device. The system then compares the total amount of game coins 9 that should have been in the game coin tray 17 after the game is cleared at the end of the game with the actual total amount of game coins 9 in the game coin tray 17 at the end of the game obtained by the image analysis device 12, and determines whether there is a difference between the total amount that should have been in the game and the actual total amount.

[0111] The control device 14 uses the image analysis device 12 to grasp the position, type and number of game coins placed by each player. When all the lost game coins placed by each player are collected, the control device 14 grasps the actual total amount of game coins in the game coin tray. The control device 14 compares the total amount of game coins in the game coin tray before the settlement of each game with the actual total amount of game coins in the game coin tray 17 obtained by adding the increase of the game coin tray 17 in the game according to the position, type and number of game coins placed by the losing players on page 9 / 19 of the instruction manual 12 CN 121121919 A, and determines whether there is a difference between the expected total amount and the actual total amount.

[0112] The control device 14 compares the total amount of game coins 9 in the game coin tray 17 before the settlement of each game with the actual total amount of game coins 9 in the game coin tray 17, which is obtained by adding the increase of the game coin tray 17 in the game based on the position, type and number of game coins 9 placed by the losing player. If there is no difference between the expected total amount and the actual total amount, the control device 14 compares the expected total amount in the game coin tray 17 after the game ends with the actual total amount of game coins 9 in the game coin tray 17 obtained by the image analysis device 12 after the game ends. If there is a difference between the expected total amount and the actual total amount, the control device 14 determines that there is a payment error and generates a payment error signal to notify of the payment error.

[0113] The game coin tray 17 is provided with a game coin collection tray 171 for temporarily storing and collecting game coins 9 placed by losing players. The image analysis device 12 compares the total amount of game coins 9 in the collection tray 171, which is calculated based on the position, type, and number of game coins 9L placed by the losing players, with the actual total amount of game coins 9 in the collection tray 171, and determines whether there is a difference between the total amount and the actual total amount.

[0114] In order to analyze the game record of the game that caused the difference when the control device 14 determines that the actual total amount of game coins 9 held in the game coin tray 17 of the dealer 5 of the game table 4 does not correspond to the increase or decrease of game coins calculated based on the amount of game coins placed by all players and the winning or losing result of the game, the game record device 11 is configured to index or time the acquired image, or to determine and reproduce the scene of collecting or paying game coins 9.

[0115] Thus, the control device 14 obtains the total amount of game coins in the game coin tray 17 after the game ends by means of the image analysis device 12. However, the determination after the settlement in this case is made when any of the following 1) to 4) occurs:

[0116] 1) When the repayment of the won game coins 9 ends;

[0117] 2) When the card C used in the game is collected and discarded in the discard area 41 or discard slit 42 of the table;

[0118] 3) When the prescribed button attached to the win / loss result determination device is pressed;

[0119] 4) When the sign 43 indicating win / loss is restored.

[0120] Furthermore, the control device 14 is configured to effectively utilize artificial intelligence or deep learning, capable of grasping the position (position of P, B, or PAIR) and amount (type and number) of game coins placed at each play position 7 of the game table 4, comparing the win / loss history of each player 6 obtained from the win / loss results of each game with the amount of game coins won (the amount won), and extracting it as an anomaly (set by the casino). Typically, it is a device equipped with a control device 14 configured to effectively utilize artificial intelligence or deep learning, capable of extracting it as an anomaly when comparing it with the statistical data of past games (big data, etc.) when the occurrence of a winning amount of more than a certain amount (1 million points) or the state where the amount of game coins placed when losing at a certain play position 7 of the game table 4 is small and the amount of game coins placed when winning is large in multiple games.

[0121] Furthermore, the control device 14 of this cheating detection system (integrated with the image analysis device 12) is configured to identify individual players 6 who have been identified as abnormal situations or who have won a specified amount or more at the playing position 7. For the identification of such players 6, the image analysis device 12 obtains an image of their face through feature point extraction, etc., and assigns an identification number (ID, etc.) to them. Moreover, the control device 14 has a warning function that notifies other gaming tables of the presence of the identified player 6 when they leave their seat and sit at another gaming table. Specifically, it notifies the manager of each gaming table 4 or the person in charge of each table (or the dealer) to prevent further abnormalities.

[0122] The control device 14 also has a database that stores purchase history records of game coins 9 purchased with banknotes K. By referring to the database at certain intervals or on a daily basis, it compares and determines whether the amount of game coins 9 held in the game coin tray 17 of the dealer 5 at the game table 4 has been reduced based on the payment amount of game coins 9 corresponding to the banknotes K used for purchase, or the total amount of payment amount of banknotes K corresponding to the purchased game coins 9.

[0123] Furthermore, in the above example, it is also possible to monitor the win / loss history and the amount of game coins (winnings) of each playing position 7 without knowing the individual player 6. In this case, although it is not possible to track and investigate each player 6 when they leave their seats, it is possible to detect abnormal situations such as the state that the amount of game coins placed when losing is small and the amount of game coins placed when winning is large in a specific playing position 7 of the game table 4 continues in multiple games. Moreover, when such a playing position 7 is detected, cheating or errors are suspected at that playing position 7. Moreover, by verifying the video of the playing position 7, cheating or errors can be found.

[0124] Specifically, the camera 2 is set to capture at least the game coins 9 placed in the placement area 8 of the game table 4. The image analysis device 12 analyzes the image captured by the camera 2 and, according to each user position 7, detects which position of the placement area 8 (P, B, tie) has game coins placed and the amount of game coins placed. Moreover, the card dispensing device 3 functions as a win / loss result determination device to determine the win / loss result of the game. The control device 14 records (monitors) the win / loss history and the amount of game coins obtained (game coin winnings) for each playing position 7 based on the position (P, B, or tie) within the placement area 8 where game coins 9 are placed and the game's winning / losing results. Alternatively, only either the win / loss history or the game coin winnings can be recorded. If the control device 14 determines that a player's position 7 is suspected of cheating when comparing the win / loss history and / or the game coin winnings history with statistical data from many past (big data) games and finds an anomaly (set by the casino), then that player's position 7 is identified as a playing position suspected of cheating.

[0125] In the event of suspected cheating at a player's position 7, the cheating detection system generates an alarm (light, sound, or vibration) in a manner that at least the dealer can detect at that time. This prevents the continuation of cheating by at least interrupting subsequent games at that location. Additionally, information indicating suspected cheating can be added to the video captured and recorded by the camera 2. This allows for investigation of the cause of suspected cheating by reviewing the video.

[0126] The cheating detection system in the amusement park with game tables of this embodiment also has the function of checking when purchasing game tokens with paper money and game coins repeatedly at the game table 4. In amusement parks such as casinos, before the game, player 6 purchases game coins with paper money (cash, etc.) at a designated game coin purchase location. However, when player 6 runs out of game coins, without leaving the game table 4, they can purchase game coins 9 with cash (paper money) at the game table and continue playing. However, this creates an opportunity for cheating between the dealer 5 and the player. Purchasing game coins 9 with cash (paper money) at the game table needs to be done when not playing a game.In order to determine the winner of the game, the card dispensing device 3 can detect the start and end of card dispensing (the period for determining the winner). Therefore, the card dispensing device 3 detects situations other than card dispensing (dispensing), and the control device 14 detects that a game coin 9 is being purchased with paper money at the game table 4 (shown in Figure 6) in situations other than card dispensing. For situations other than card dispensing, detection can be performed based on information obtained from the actions of the card dispensing device 3 or the dealer 5.

[0127] The control device 14 performs image analysis on the surface of the paper money K and can identify the number and amount of paper money. Furthermore, at the game table 4, the authenticity of the paper money K used to purchase the game coin 9 is verified by irradiating it with near-ultraviolet light to detect the authenticity mark G of the paper money. As shown in Figure 6, the control device 14 is constructed using artificial intelligence or deep learning in the following way: [Instruction manual 11 / 19 pages 14 CN 121121919 A] Image analysis is also performed on the authenticity mark G to verify it, recognizing the total amount of the real banknotes. Even if multiple game coins taken from the game table as purchase objects are hidden due to the blind spot of the camera 2, the total amount of the game coins can still be recognized. The total amount of banknotes K taken from the player on the game table 4 and the total amount of game coins 9 taken from the dealer 5 can be compared to determine whether the two amounts are consistent.

[0128] The control device 14 is constructed using artificial intelligence or deep learning in the following way: It can compare and calculate the total amount of game coins 9 in the dealer 5's game coin tray 17 on the game table 4, and after purchasing game coins with banknotes and settling accounts, whether a deduction was made based on the payment amount of game coins corresponding to the banknotes used for purchase. It is also possible to consider using the RFID of game coins 9 to pre-monitor the total amount of game coins 9 in the dealer 5's game coin tray 17. In addition, by using camera 2 to photograph the game coin tray 17 containing game coins 9, and analyzing the image using image analysis device 12, the total amount of game coins 9 stored in the game coin tray 17 can also be detected.

[0129] Moreover, control device 14 verifies whether the reduction in the amount of game coins 9 in the game coin tray 17 before and after purchasing game coins with paper money is consistent with the amount of game coins paid as shown in the image analysis on the game table 4. The amount of paper money already paid can be input by the dealer 5 through keyboard input or the like into control device 14, or the camera 2 can photograph the game table 4 where paper money payment is made, and the image can be analyzed by image analysis device 12 to determine this.

[0130] As described above, control device 14 determines whether the reduction in the amount of game coins 9 in the game coin tray 17 caused by purchasing game coins with paper money is consistent with the amount of paper money paid by player 6 to dealer 5.Furthermore, the control device 14 is an intelligent control device capable of comparing and calculating the consistency between the amount of banknotes received by the dealer 5 (usually based on keyboard input, etc.) and the calculated amount of banknotes based on the image analysis results of the image analysis device 12 after purchasing game coins with banknotes and clearing the account. It can also be an artificial intelligence-efficient or deep learning-based device.

[0131] In addition, the control device 14 is an artificial intelligence-efficient or deep learning-based device capable of comparing and calculating the consistency between the total amount of banknotes input by the dealer at the game table 4 under the dealer's responsibility and the total amount of banknotes based on the image analysis results of the image analysis device 12.

[0132] The control device 14 compares and determines whether the amount of game coins 9 held in the game coin tray 17 of the dealer 5 at the game table 4 has been reduced after purchasing game coins 9 with banknotes, based on the payment amount of game coins 9 corresponding to the banknotes used for purchase or the payment amount of banknotes corresponding to the purchased game coins 9.

[0133] (Second Embodiment)

[0134] Among the many table games played in amusement parks such as casinos, there is a certain card game. These games use a standard deck of cards consisting of 52 cards. The cards are dealt to the game table from a card dispensing device equipped with multiple decks (from 6 to 9 or 10 decks) that have been pre-shuffled. The winner is determined based on the number of cards dealt (card rank) and the game rules.

[0135] The dispensing of cards from the card dispensing device and the calculation of the amount placed by the guests (game participants) are performed by the dealer or others in charge of the game table. In amusement parks such as casinos, attempts are being made to prevent errors and cheating in the calculation of the amount placed by the guests (game participants).

[0136] In the card game monitoring system described in International Publication WO2015 / 107902, a surveillance camera is used to read the changes in game coins and check whether the amount placed has been paid to the winner.

[0137] Regarding the placement of guests in a certain card game and the calculation of the amount of cards placed by the dealer for the guests (game participants), there are the following problems: it is impossible to detect the time when these actions are taken, who places the game coins, or whether they have been taken away, so it is impossible to ascertain whether these are correct.

[0138] To solve the above-mentioned problems, the cheating detection system of the second embodiment is a cheating detection system for an amusement park with a game table, comprising:

[0139] A game monitoring device that uses a camera to monitor the progress of games played at the game table;

[0140] An image analysis device that performs image analysis on images obtained using the camera;

[0141] A card dispensing device that determines and displays the winning and losing results of each game at the game table; and

[0142] A control device that uses the analysis results of the image analysis device in each game to determine the position of game coins placed on the game table by the game participants, and uses the winning and losing results to determine the winner and loser among the participants of each game;

[0143] The control device further comprises the function of determining at least one of the following:

[0144] 1) In each game, from the time the starting cards are drawn or from the time the dealer starts the game until the result of the game is displayed by the card dispensing device, are there any changes in the game coins?

[0145] 2) After each game ends, during the period when the dealer collects the game coins placed by the losers among the game participants, are there any changes in the game coins caused by anyone other than the dealer?

[0146] 3) After each game ends, during the period when the dealer collects the game coins placed by the losers among the game participants, are any additional game coins added?

[0147] 4) After each game ends, does the dealer pay out the game coins placed by the winners among the game participants?

[0148] 5) After each game ends, do the winners among the game participants take out the placed game coins and the game coins that were paid out?

[0149] Furthermore, the control device may also be configured to detect changes in the hands of the dealer and game participants, changes in game coins, or changes in both hands and game coins, by using the analysis results of the image analysis device, thereby determining at least one of 1) to 5).

[0150] Furthermore, the control device may also be configured to determine whether the amount of game coins paid by the dealer to the winner is correct based on the amount placed by the winner among the game participants.

[0151] Furthermore, the cheating detection system for the game may also include a monitor or light that receives the determination result and issues a warning or display.

[0152] According to the cheating detection system of this embodiment, the system can detect the timing of the placement made by a guest in a card game and the calculation of the placement amount made by the dealer for the guest (game participant), who placed the game coins, or whether they have been taken away, and can detect and issue warnings or displays regarding these errors and cheating behaviors, thereby preventing recurrence.

[0153] Before proceeding to the detailed description of this embodiment, the process of a certain card game played in an amusement park or similar venue will be described. Furthermore, in this second embodiment, the same configurations as in the first embodiment will be described with the same numbering.

[0154] As shown in FIG7, at the game table 4, a guest (game participant / player) 6 and a dealer 5 sit facing each other at the playing position (chair) 7. The guest (game participant) 6 places game coins 9 in the placement area 8 in front of them, determining which player (PLAYER) or banker (BANKER) will win, or if the game ends in a tie (hereinafter, this will be referred to as "placement"). The dealer 5, to complete the placement by the guest (game participant) 6, times the timer, shouts "No More Bet (placement completed)," and performs actions such as moving their hand laterally (as shown in FIG7). In a certain card game, from the moment the card is drawn ("No More Bet" is shouted, or the dealer 5 starts the game), until the game result is displayed by the card dispensing device 3, the guest (game participant) 6 cannot move the game tokens, place additional game tokens, or retrieve placed game tokens.

[0155] Afterwards, the game cards 1 are drawn one by one from the card dispensing device 3 onto the game table 4, face down. First, four cards are drawn, as shown in ①~④ of Figure 8. The first card belongs to P (PLAYER), the second card to B (BANKER), the third card to P (PLAYER), and the fourth card to B (BANKER), arranged in areas 10 (P area 10P and B area 10B) visible from the dealer 5 on the game table 4. Furthermore, based on the face value (number) of the first to fourth cards 1 and the conditions in the detailed rules of a certain card game, the dealer 5 draws the fifth card 1 and the sixth card 1, which belong to P (PLAYER) or B (BANKER). Next, based on the face value (number) of the first to fourth cards 1 (and, depending on the situation, the fifth and sixth cards 1) and the detailed rules of a certain card game, the winner of the game is determined. Here, the rules of the game are pre-programmed in the card dispensing device 3, which can read the information of the distributed cards 1 (face value (number) and suit) to determine the winner of the game. The winner determination result (win result) determined by the card dispensing device 3 is judged to be consistent with the winner determination result determined by the dealer, etc., as described above.

[0156] Hereinafter, an overall overview of the cheating detection system in the game of the amusement park according to the embodiment of the present invention will be described.Figure 7 is a schematic diagram showing the overall system. The cheating detection system in the game room includes: a game recording device 11, which records the progress of the game at the game table 4, including the guests (game participants) 6 and the dealer 5, as images via a camera 2; an image analysis device 12, which performs image analysis on the recorded game progress images; and a card dispensing device 3, which has the function of determining and displaying the win / loss results of each game at the game table 4. The card dispensing device 3 is a so-called electronic shoe used by those skilled in the art, constructed to pre-program the game rules, and can detect when the dealer 5 distributes the cards 1 at the start of each game, and read the information of each distributed card 1 (card value and suit) to determine the win / loss of the game. For example, in a certain card game, the win for player B, the win for player P, and a draw are basically determined by the value of 2-3 cards, and the determination result (win / loss result) is displayed via an indicator light 13.

[0157] The control device 14 of this cheating detection system has a game coin detection function. This function uses the analysis results of the image analysis device 12 in each game to determine which placement area 8, P side or B side, the guest 6 (game participant) has placed the game coin 9 on. Regarding the position and total amount of the game coin 9 (which placement area 8, P side or B side, has the game coin 9 placed in), it is conceivable that if the game coins 9 are staggered or overlapped, or if they fall into a blind spot from the position of the camera 2, they are usually not readable. The control device 14 is configured to use a computer or control system based on existing artificial intelligence, a self-learning function based on deep learning (construction) technology, etc., to identify the concealment of the game coin 9 due to blind spots (partial concealment of a single game coin, or complete concealment of the game coin), and accurately grasp the position and number of coins. Furthermore, the configuration for detecting the position and type of the game coin 9 in the placement area 8 is not limited to this; for example, it can also be configured to detect by reading the ID embedded in the game coin.

[0158] As described above, the control device 14 can, with the aid of the camera 2 and the image analysis device 12, determine the position (placement for P, B, or PAIR), type (different values ​​are assigned to each color of the game coin 9), and number of coins placed by each player 6. It can detect which player 6 placed the coin for P (if there are multiple players 6 placing the coin for P, the player 6 who placed the highest value), and which player 6 placed the coin for B (if there are multiple players 6 placing the coin for B, the player 6 who placed the highest value). The image analysis device 12 and the control device 14 in this cheating detection system are constructed as a single unit or as a composite unit, comprising a computer, a program, and a memory.

[0159] The control device 14 is configured to compare the card size and suit information obtained by the image analysis device 12 from the image of each card 1 distributed at the game table 4 (using the camera 2) with the card size and suit information read by the card distribution device 3, and determine whether they are consistent or not. According to the game win or loss result determined by the card distribution device 3 in each game, the control device 14 analyzes the image of the game progress state by means of the image analysis device 12 to determine whether the recovery of the lost game coins 9 placed by the guest (game participant) 6 and the payment of the won game coins to the winning guest (game participant) 6 are correctly performed according to the game win or loss result.

[0160] The control device 14 has the functions shown in 1) to 5) below according to the rules of a certain card game. As a characteristic function of the present invention, it determines whether cheating that violates the rules has not been carried out. That is,

[0161] 1) In each game, the information obtained by the image analysis device 12 using the camera 2 is used to monitor (as shown in FIG8) whether there is any change in the game coin 9 from the signal of the starting card being drawn from the card dispensing device 3, or from the start of the game operation when the dealer 5 presses the start button for 4 seconds, until the game result is displayed by the card dispensing device 3.

[0162] 2) After each game ends, the information obtained by the image analysis device 12 using the camera 2 is used to monitor whether the loser 6 has taken the game coin 9 without cheating during the period when the dealer 5 collects the game coin 9 placed by the loser among the game participants 6 (as shown in FIG9).

[0163] 3) After each game, the information obtained by the image analysis device 12 using the camera 2 is used to monitor whether anyone other than the dealer 5 (winner or loser) added the won game coins 9W, or whether the game coins 9 were not placed on the winning side, during the period when the dealer 5 was collecting the game coins 9 placed by the loser among the game participants.

[0164] 4) After each game, the information obtained by the image analysis device 12 using the camera 2 is used to monitor whether the dealer 5 correctly placed the paid game coins 9W at the position of the game coins 9 placed by the winner among the game participants 6 (as shown in Figure 10).

[0165] 5) After each game (the dealer 5 operates the card dispensing device 3 and displays the winning and losing results on the display light 13), the information obtained by the image analysis device 12 using the camera 2 is used to monitor whether the winner 6W among the game participants 6 took the placed game coins 9 and the paid game coins 9W (as shown in Figure 11).

[0166] The control device 14 analyzes the information obtained by the image analysis device 12 using the camera 2 as follows.That is, by using the analysis results of the image analysis device 12, the changes in the hands of the dealer 5 and the game participant 6, the changes in the game coin, or the changes in the hands and the changes in the game coin are detected to monitor 1) to 5). However, in this basic analysis, it is necessary to know at least who took the game coin 9. Hereinafter, the method of this analysis will be described using the following Figures 12 to 14.

[0167] Analysis of the case where the dealer 5 takes the game coin 9 placed by the game participant 6L (Figure 12).

[0168] The dealer 5 retrieves the game coin 9 placed by the losing game participant 6L. The information obtained by the image analysis device 12 using the camera 2 is analyzed to monitor whether it has indeed been retrieved. First, the change of the placed game coin 9 from the present state (Figure 12A) to the non-present state (Figure 12C) is detected by image analysis. Then, the image of the game coin 9 during the period from the present state to the non-present state (Figure 12B) is analyzed. In the image (Fig. 12B) during the period from when the game coin 9 is present to when it is absent, the direction from which the hand 5h extends (from above or outside of Fig. 12) is analyzed. If the hand extends from above (or the hand appears from above and then moves back upwards), the hand 5h is determined to belong to the dealer 5. If the hand extends from a direction other than this, it is determined to be cheating. Cheating is detected according to this rule.

[0169] During the period when the dealer 5 collects the game coin 9 placed by the losing player 6L, the other players are monitored to see if they have taken the lost game coin 9 without cheating (Figs. 12 and 11). In the image during the period from when the game coin 9 is present to when it is absent, as shown in Fig. 13, the analysis of the case where the losing player 6L or others among the game participants 6 took the game coin 9 is performed by detecting that the hand 6h extends or moves from below (originally from above) in Fig. 13. This is determined to be the hand 6h or others other than the dealer 5 taking the game coin 9, and this is determined to be cheating. Instruction manual, pages 15 / 19, 18 CN 121121919 A ​​

[0170] Analysis of the situation where the dealer 5 correctly pays (places) the won game coins 9W, which are then taken by the winner 6W among the game participants 6. First, the won game coins shown in Figure 14A are paid back according to the rules of the game, as shown in Figure 14B. The change from the state shown in Figure 14A to the state shown in Figure 14B is detected, and at the same time, the hand is detected by image analysis to determine whether it is the dealer 5's hand 5h. Afterwards, the control device 4 checks, according to the rules of the game and based on the image analysis results, whether the winner 6W's hand 6h among the game participants 6 extends (moves) to the same placement area as shown in Figure 14C, and then all the game coins 9 disappear (the state in Figure 14D), thereby determining whether there is any cheating.

[0171] Furthermore, the control device 4 is configured to determine whether the amount of game coins paid by the dealer 5 to the winner is correct based on the amount placed by the winner 6W among the game participants 6. Specific examples are shown below. Regarding the position and total amount of the game coin 9 (which placement area 8 on the P side or B side the game coin 9 is placed in), it is conceivable that it cannot be read if the game coins 9 are misaligned or overlapped, or if they fall into a blind spot from the position of the camera 2. The control device 14 is configured to use a computer or control system based on existing artificial intelligence, a self-learning function based on deep learning (construction) technology, etc., to identify the concealment of the game coin 9 due to blind spots (partial concealment of a single game coin, or complete concealment of the game coin), and accurately grasp the position and number of coins. Furthermore, the configuration for detecting the position 8 and type of the game coin 9 in the placement area 8 is not limited to this; for example, it can also be configured to detect by reading the ID embedded in the game coin.

[0172] As described above, the control device 14 can use the camera 2 and image analysis device 12 to determine the position 8 (placement of the game coins 9 placed by each player 6, whether it is P, B, or PAIR), type (the game coins 9 are assigned different values ​​according to each color), and number of coins. It can detect which player 6 placed the coin to P (if there are multiple players 6 placed to P, the player 6 who placed the highest value), and which player 6 placed the coin to B (if there are multiple players 6 placed to B, the player 6 who placed the highest value).

[0173] Furthermore, the control device 14 of the cheat detection system of this game, according to the rules of a certain card game, analyzes the information obtained by the image analysis device 12 using the camera 2 and monitors it using the methods described above. By performing the monitoring shown in 1) to 5) above, it determines whether cheating that violates the rules has been committed. When cheating is detected, the card distribution detection device 14C illuminates the abnormal indicator lights 16 installed on both the card distribution device 3 and the game table 4, and outputs the detection of cheating to the casino management department or the like via wireless or wired transmission 15. It is also possible to further have monitors or lights in other locations that receive the judgment results and issue warnings or displays.

[0174] As described above, when cheating is detected by the control device 14, a display signal is sent to the indicator light 13 or abnormal indicator light 16 of the card distribution device 3 at the time of detection or at an appropriate moment. However, in addition to issuing a warning, it is also possible to activate the card distribution blocking function of the card distribution device 3 after the time of detection of cheating or error, thus preventing the distribution of card 1.

[0175] Hereinafter, an embodiment of the card distribution device 3 used in the table game system of the present invention will be described using FIGS. 15 to 19.The card dispensing device 3 includes: a card storage section 102 that stores multiple shuffled game cards 1s; a card guiding section 105 that guides the shuffled game cards 1 one by one as the dealer 5 and others manually draw them out of the card storage section 102 and onto the game table 4; and an opening section 106 for retrieving the cards 1 guided by the card guiding section 105. The card detection unit (card detection sensors 22 and 23) detects the removal of the shuffled game cards 1; the card reading unit 108 reads information indicating the minimum number (card rank) of the shuffled game cards 1; the control unit 109 determines the winner of the card game based on the number (card rank) of the shuffled game cards 1 read sequentially by the card reading unit 108; the result display light 13 displays the winner determined by the control unit 109; the dispensing restriction device 30 is provided at the opening 106 to restrict the entry and exit of cards 1 into the card receiving section 102; and the management control unit 114 has the same functions as the control device 14. These are integrated and have the following functions: detecting errors by the dealer in the game by the control device 14. In the event of cheating, the card dispenser prevents cards from being drawn from the card dispenser 3 at a specified time after the point at which the error or cheating is detected.

[0176] Next, the dispensing restriction device 30 that restricts the entry and exit of cards 1 in the card receiving section 102 will be described using Figures 17 and 16. The dispensing restriction device 30 is provided in the card guide 107 of the card guide section 105, which guides cards 1 taken out one by one from the opening 106 at the front of the card receiving section 102 onto the game table 4. The dispensing restriction device 30 is configured such that when a card 1 passes through the slit 33 between the card guide section 105 and the guide cover of the card guide 107, the locking member 34 presses down on the card 1 to prevent the card 1 from entering or exiting the slit 33. The locking member 34 is driven by a solenoid or piezoelectric element, etc., and moves as shown by arrow m in a manner that allows the card 1 to be in a pressed position (restricted position) and a passable position that allows the card 1 to pass. The driving unit 35 is controlled by a control unit 109 that is directly or indirectly connected to the control device 14 via wired or wireless means, so that the locking member 34 moves between the two states of the pressed card 1 position and the passable position that allows the card 1 to pass. In the control unit 109, the rules of a certain card game are programmed and stored in advance.

[0177] Next, a variation of the dispensing restriction device 30 will be described with reference to FIG18B. The dispensing restriction device 40 in the variation has the following structure: when the card 1 passes through the slit 33 between the card guide 105 and the card guide 107 (guide cover), the locking member 36 protrudes into the slit 33 to prevent the card 1 from moving.The locking member 36 is driven by a solenoid or piezoelectric element, etc., and moves as shown by arrow m in a manner that allows the card 1 to move in two states: a position that prevents the card 1 from moving (restricted position) and a passable position that allows the card 1 to pass through. The drive unit 37 is controlled by a control unit 109 connected to the control device 14, so that the locking member 36 moves between the two states of preventing the card 1 from moving and the passable position that allows the card 1 to pass through.

[0178] Next, the details of the code reading unit 108, which reads the code 52 representing the number (number, card size) of the card 1 from the card 1 when the card 1 is manually removed from the card storage unit 102, will be described. FIG17 is a top view of the main part of the card dispensing device 3. In the figure, the code reading unit 108 is provided at the card guide unit 105, which guides the manually removed cards 1 one by one from the opening 106 in front of the card storage unit 102 onto the game table 4. The card guide 105 is an inclined surface, and card guides 107, which also serve as sensor covers, are installed on the edges on both sides. Furthermore, each of the two card guides 107 can be installed and removed using screws or the like (not shown). Removing the card guides 107 exposes the sensor group 115 of the code reading unit 108. The sensor group 115 consists of four sensors: two ultraviolet (UV) sensors 20 and 21, and object detection sensors 22 and 23.

[0179] The object detection sensors 22 and 23 are fiber optic sensors that detect the presence or absence of the card 1 and can detect the movement of the card 1. The object detection sensor 22 is located upstream of the card guide 105 along the direction of movement of the card 1, and the other object detection sensor 23 is located downstream. As shown, the two object detection sensors 22 and 23 sandwich the UV sensors 20 and 21 on the upstream and downstream sides. The UV sensors 20 and 21 are equipped with an LED (ultraviolet LED) that emits ultraviolet light and a detector. On card 1, a mark M for code 52 is printed using ultraviolet luminescent ink that emits color when exposed to ultraviolet light. When ultraviolet (near-ultraviolet) light shines on card 1, the reflected light from the mark M of code 52 on card 1 is detected by a detector. UV sensors 20 and 21 are connected to the code reading unit 108 and the control unit 109 via cables. In the code reading unit 108, the combination of marks M is determined based on the output signals of the detectors of UV sensors 20 and 21, and the number (card size) corresponding to each code 52 is determined.

[0180] For the code reading unit 108, the start and end of reading by UV sensors 20 and 21 are controlled by the control unit 109 based on the detection signals of object detection sensors 22 and 23. Moreover, the control unit 109 also determines whether card 1 has passed through card guide unit 105 normally based on the detection signals of object detection sensors 22 and 23.As shown in Figure 19, quadrilateral markers M, representing the card's face value (number) and suit (hearts or spades, etc.), are arranged in 2 columns and 4 rows along the edge of card 1. If UV sensors 20 and 21 detect marker M, they output an ON signal. In the code reading unit 108, the relative relationship between the two signals input from the two UV sensors 20 and 21 is determined. Therefore, in the code reading unit 108, the code is determined based on the relative difference between the two markers M detected by the two UV sensors 20 and 21, and the corresponding card's number (face value) and type (suit) are determined.

[0181] Figure 19 shows the relationship between code 52 and the output of the ON signals of the two UV sensors 20 and 21. Based on the comparison results of the relative changes in the output of the ON signals of the UV sensors 20 and 21, the specified combination of markers M can be determined. As a result, if there are four possible combinations of markers M in the top and bottom two columns, and these are printed in four columns, then 256 codes can be formed, which is four to the power of four. The 52 types of game cards are assigned to one of these 256 codes, and this is stored as a lookup table in memory or by a program. The code reading unit 108 is configured to determine the number (card size) and type (suit) of card 1 by determining each code 52 and referring to a pre-set lookup table (not shown). Furthermore, a correspondence can be established between the 256 codes and the 52 cards in a freely combinable manner, stored through a lookup table, thus allowing for complex combinations that can vary with time and place. Preferably, the codes are printed using a paint that is visible under ultraviolet light, and are printed in a position that does not overlap with the card type notation and index 103.

[0182] Furthermore, in the above embodiments, the image analysis device 12 and the control device 14 are devices with artificial intelligence-efficient or deep learning structures. However, specifically, the image analysis device 12 and the control device 14 can perform image analysis and the various controls described above using scale-invariant feature transform (SIFT), convolutional neural network (CNN), deep learning, machine learning, or similar methods. These techniques are techniques for image recognition of camera images to identify objects contained within the images. In particular, in recent years, deep learning techniques that utilize multi-layered neural networks have been used to identify objects with high accuracy. This deep learning technique generally identifies objects with high accuracy by overlapping layers across multiple stages in the intermediate layers between the input and output layers of the neural network.In this deep learning technology, especially convolutional neural networks, there is a high level of performance compared to object recognition based on existing image feature quantities, which has attracted attention.

[0183] In a convolutional neural network, labeled object images are learned, and the main objects contained in the object images are identified. When there are multiple main objects in the learning image, a region rectangle is used to specify the region, and the image corresponding to the specified region is labeled and learned. Furthermore, in a convolutional neural network, it is also possible to determine the main object in the image and the position of the object.

[0184] If we further explain the convolutional neural network, in the object recognition process, by performing edge extraction processing on the object image, candidate regions are extracted based on local features, and the candidate regions are input into the convolutional neural network. Based on the extracted feature vectors, classification is performed, and the candidate region with the highest confidence level is obtained as the recognition result. The so-called confidence level is a measure of how much higher the similarity between a certain image region and the main body of the image learned with the label is compared to other levels of similarity.

[0185] Furthermore, devices with artificial intelligence-efficient or deep learning-based structures are described in U.S. Patent No. 9,361,577, U.S. Patent Publication No. 2016-171,336, U.S. Publication No. 2015-036,920, and Japanese Patent Publication No. 2016-110,232, etc., and these descriptions are incorporated herein by reference.

[0186] Various embodiments of the present invention have been described above, but of course, those skilled in the art can modify these embodiments within the scope of the present invention, and the device of this embodiment can be appropriately modified according to the needs of the applicable game.
