Abstract

Both RFID tags and cameras are utilized to identify placed game coins for roulette games to assist dealers in operation. A control device (140) reads an RFID tag (104) using a placement area antenna (131) and acquires a first read result with respect to selected game coins remaining after a dealer recovers non-selected game coins in a wheel disc (11), captures the selected game coins using a plurality of cameras (14, 15, 16) and acquires a first image, analyzes the first image using an analysis device (110), and transmits the analyzed first image to the wheel disc (11). Subtracting the number of each color of the selected game currency capable of being identified by the image from the number of each color of the selected game currency shown by the first reading result to determine the number of each color of the selected game currency capable of being identified by the image, which is not shielded in any of the first images, so as to determine the number of each color of the selected game currency capable of being identified by the image; the number of each color of the obscured selected game currency which is obscured in any first image is determined, and for the number of each color of the image-recognizable selected game currency and the obscured selected game currency, the apportionment amount of each color is calculated on the basis of the apportionment magnification of each color of the image-recognizable selected game currency.

Description

Technical Field

[0001] The present invention relates to a management system for managing a roulette game played on a roulette game table using roulette game coins. Background Art

[0002] In recent years, a system has been proposed in entertainment facilities for identifying placed game coins (hereinafter also referred to as "placed game coins") during a game played on a game table using game coins by reading an RFID tag built into the game coins or photographing the game coins with a camera and performing image analysis. This system also assists the dealer in operations such as the recovery of the placed game coins and the allocation of the placed game coins according to the game results (for example, see Patent Document 1).

[0003] Among them, when the placed game coins are detected by reading the RFID tag built into the placed game coins, as long as there is no abnormality in the RFID tag, the placed game coins can be read relatively accurately. However, on the other hand, when using RFID, it is often difficult to accurately distinguish and identify the location where the placed game coins are placed (this indicates the placement object).

[0004] On the one hand, when shooting the placed game coins with a camera, the position where the placed game coins are placed can be identified more accurately. However, there is a situation where the placed game coins that enter the blind spot of the camera due to other placed game coins cannot be identified.

[0008] Problems to be solved by the invention

[0009] The present invention aims to provide a system for identifying placed game coins, particularly in roulette, and assisting the dealer in their operations. Taking into account the aforementioned advantages and disadvantages of using RFID tags and cameras for identifying placed game coins, the present invention utilizes both RFID tags and cameras to identify placed game coins in roulette, thereby assisting the dealer in their operations.

[0010] Means used to solve problems

[0011] A management system according to one embodiment is a management system for managing a roulette game played using roulette coins on a roulette table including a roulette wheel and a placement area divided into a plurality of placement target areas. In the roulette game, roulette coins having different colors for different players are used, and the roulette coins are provided with RFID tags storing information corresponding to at least their colors, and the color is displayed at least on the side, and the management system comprises: two cameras, which shoot the placement area from different obliquely upper positions and respectively generate images or videos; one or more placement area antennas, which are used to read the RFID tags in the roulette coins placed in the placement area and are built into the placement area; an analysis device, which determines the number of roulette coins of each color placed in the placement area, multiple boundaries of adjacent placement object areas, and the positional relationship between the roulette coins and the boundaries by analyzing the images or videos; a control device, which performs dealer-assisted processing of payment by controlling the at least two cameras, the one or more placement area antennas, and the analysis device; and a display, which displays the results of the dealer-assisted processing In the embodiment of the present invention, the control device is configured to use the one or more placement area antennas to read the RFID tag and obtain a first reading result for the selected game coins that remain after the game result is determined in the roulette wheel and the dealer collects the non-selected game coins, and use the at least two cameras to shoot the selected game coins and obtain a first image or video, and use the analysis device to analyze the first image or video, so as to determine the number of each color of the image-identifiable selected game coins that are not blocked by any of the first images or videos, subtract the number of each color of the image-identifiable selected game coins from the number of each color of the selected game coins represented by the first reading result, so as to determine the number of each color of the blocked selected game coins that are blocked by any of the first images or videos, and calculate the allocation amount of each color of the game coins based on the respective allocation multipliers for the number of each color of the image-identifiable selected game coins and the blocked selected game coins, and the display shows the allocation amount of each color of the game coins calculated by the control device.

[0012] According to this structure, for the selected game coins, the control device grasps the position where they are placed and the number of coins of each color, calculates the share of each color, and displays it on the display. Therefore, the dealer can easily identify how much share is given to the game coins of which color placed in which position by confirming the display.

[0013] The above-mentioned management system also has an antenna for recovering game coins, which is used to read the RFID tags of the non-selected game coins recovered by the dealer. The control device is configured to use the one or more placement area antennas to read the RFID tags of all the roulette game coins placed in the placement area and obtain a second reading result, and use the game coin recovery antenna to read the RFID tags of the non-selected game coins and obtain a third reading result. If the result obtained by subtracting the number of each color of the non-selected game coins represented by the third reading result from the number of each color of all the placed roulette game coins represented by the second reading result is inconsistent with the number of each color of the selected game coins represented by the first reading result, an alarm is output.

[0014] According to this configuration, when there is cheating in the collection of non-selected tokens, an alarm can be output.

[0015] The above-mentioned management system also includes: a player identification system, which determines the relationship between the player participating in the roulette game and the color of the roulette game token allocated to the player; and a recording device, which records the historical records and / or accumulations of the placement amounts of each player, and the control device determines the historical records and / or accumulations to be recorded in the recording device based on the number of each color of all the roulette game tokens placed as represented by the second reading result.

[0016] According to this structure, it is possible to record the player's bet amount history and / or accumulated customer ratings. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Hereinafter, the modes for carrying out the present invention will be described, but the embodiments described below are merely examples and the present invention is not limited to the embodiments described below.

[0030] (Overview of the Roulette Table)

[0031] Figure 1 is a perspective view showing a roulette table to which the management system of this embodiment is applied. Figure 2 FIG. 1 is a top view of a roulette table to which the management system of this embodiment is applied. Figure 1 and Figure 2 As shown, a roulette table (hereinafter referred to as the "game table") 10 has a roulette wheel 11 in one corner. Next to the roulette wheel 11 is a dealer coin area 12 for placing the dealer's coins. The dealer deals the cards at the dealer position, which is located in the center of the opposite side of the roulette wheel 11.

[0032] On the tabletop, a placement area 13 is arranged from the center of the game table 10 to the end opposite to the roulette wheel 11. Figure 1 and Figure 2In the example shown, a roulette wheel 11 is provided on the dealer's right hand side, a dealer's coin area 12 is provided in front of the dealer's right hand side, and a placement area 13 is provided from the front to the left. Multiple players are located in player positions and place coins on placement area 13. The player positions are arranged around the gaming table 10 so as to avoid the dealer's position and surround placement area 13.

[0033] The gaming table 10 is equipped with a first camera 14, a second camera 15, and a third camera 16 for capturing images of the placement area 13. The first camera 14, the second camera 15, and the third camera 16 are all mounted on a pole erected on the gaming table 10. The first camera 14 is located at a corner of the gaming table 10 where the roulette wheel 11 is located. The second camera 15 is located at a corner of the gaming table 10 where the dealer's coin area 12 is located. The third camera 16 is located at a corner of the gaming table diagonally opposite the first camera 14. It is desirable that the first camera 14, the second camera 15, and the third camera 16 are all located in positions that do not interfere with players placing their coins or the dealer collecting and paying out coins.

[0034] The first camera 14, the second camera 15, and the third camera 16 shoot the placement area 13 from obliquely above to obliquely below. The first camera 14, the second camera 15, and the third camera 16 shoot the placement area 13 from different directions. Figure 1 In the example of FIG, the first camera 14, the second camera 15, and the third camera 16 are set at approximately the same height from the table, but the heights of the first camera 14, the second camera 15, and the third camera 16 may be different from each other.

[0035] A display 17 is also provided next to the roulette wheel 11 of the gaming table 10. This display 17 faces the dealer and displays the dealer assistance screen described below. The display 17 is also mounted on a pole erected on the gaming table 10, but alternatively, it can be embedded in the tabletop. Furthermore, while the display 17 is located within the gaming table 10 in this embodiment, it can also be located at the edge of the gaming table 10 so as not to obstruct the dealer's dealing of cards. Furthermore, the display 17 can be oriented in a direction that is visible not only to the dealer but also to the players.

[0036] (Placement Area and Placement)

[0037] Figure 3 This is a diagram showing an example of the placement area of ​​this embodiment. The placement area of ​​the roulette game has European style and American style. Figure 3 The example of FIG shows an American-style placement area. It should be noted that the present invention can also be applied to a European-style placement area.

[0038] In this embodiment, the small areas divided within the placement area 13 are referred to as "placement target areas." The placement area 13 is generally divided into an inner placement area, which consists of placement target areas assigned the numbers 0, 00, and 1 to 36, and an outer placement area, which consists of the remaining placement target areas. The outer placement target area includes a column area for placing 12 placement targets in a horizontal column; a twelve-area area for placing the first 12 placement targets, the middle 12 placement targets, or the last 12 placement targets; a low / high area for placing the 18 placement targets from 1 to 18 or the 18 placement targets from 19 to 36; an odd / even area for placing the 18 odd-numbered placement targets or the 18 even-numbered placement targets; and a red / black area for placing the 18 red placement targets or the 18 black placement targets.

[0039] Figure 4 It is a figure showing an example of a game coin placed in the placement area of ​​the present embodiment. It is possible to place the game coin by placing it in a small area as a placement object area. In the inner placement area, by placing it on the boundary of the placement object area, it is also possible to place the placement objects on both sides of the boundary at the same time. Like game coin C11 and game coin C15, when placing the game coin in a manner across the placement object areas placed on the two inner sides, when placed on the boundary, then the two placement objects (game coin C11 is to No. 17 and No. 20, game coin C15 is to No. 19 and No. 20) are placed (divided bets). Like game coin C12 and game coin C14, when placing the game coin in a manner across the placement object areas placed on four inner sides, when placed on the intersection of the placement boundary, then all the placement objects of the four placement objects (game coin C12 is to No. 17, No. 18, No. 20 and No. 21, game coin C14 is to No. 20, 21, No. 23 and No. 24) are placed (corner bets).

[0040] Like the game coin C13, when the game coin is placed in the placement object area placed inside without touching any border, only the placement object (in Figure 4 In the case of placing a coin on the boundary between the inner placement object area and the twelve areas, the coin is placed (direct selection) in the corresponding vertical direction. Figure 4 In the case of the coin C18, it is 28 to 30) and is placed (street bet). Like the coin C17, when the coin is placed on the boundary between the two placement object areas and the twelve areas, it is placed on the corresponding two columns of six placement objects ( Figure 4In the case of the coin C17, it is placed at 7 to 12 (double street bet). Like the coin C16, when the coin is placed at the intersection of the 1st, 0th, and 12th area boundaries, it is placed towards the corresponding 5 vertical placement objects ( Figure 4 In the case of the game coin C16, it is placed (five numbers) for 0, 00, 1 to 3. Like the game coin C19, when the game coin is placed in the column area, it is placed to the corresponding 12 horizontal objects (in Figure 4 In the case of the game coin C19, it is placed (listed) for No. 2, No. 5, ... No. 35).

[0041] For each of the above placements, on the basis of ensuring the organizer's profit (deduction rate), define the organizer's odds (share amount) corresponding to the winning probability. Figure 4 In the case of the American style shown, the probability of winning with a direct bet is 1 / 38 (approximately 2.63%), but to ensure a 5.26% return for the betting team, the betting odds are set at 36. Alternatively, for example, the probability of winning with a column bet is 12 / 38 (approximately 31.58%), but to ensure a 5.26% return for the betting team, the betting odds are set at 3.

[0042] As described above, in the roulette game, the placement content varies depending on the position of the token. In the placement area 13, a plurality of placement target areas are arranged in a two-dimensional direction, and adjacent placement target areas are connected via a boundary.

[0043] (Game Currency)

[0044] The game coins used in roulette (hereinafter referred to as "game coins") are explained. Casinos offer table games such as card games, and common game coins can be used on the gaming tables of these games. However, roulette uses game coins specifically for roulette (hereinafter referred to as "roulette game coins"), which are different from the regular game coins used in these other games (hereinafter referred to as "regular game coins").

[0045] When a player starts a roulette game, they borrow roulette coins from the dealer. Roulette coins can be borrowed with cash or regular coins. Depending on the casino, this may be done only with cash or regular coins. Roulette coins have a distinguishable appearance for each set. This allows for identification of which player placed a coin in the placement area 13 when multiple players simultaneously place their coins.

[0046] Figure 5: is a perspective view showing a game coin of this embodiment. The game coin C has a group identification portion that is different for each group and a common portion that is common to multiple groups. Figure 5 In the example of , the game coin C is in the shape of a disk having two circular planes (upper surface and lower surface), and the side has a circular ring shape along the circumference of the circle. Figure 5 In the example of a game coin C, the central circular portion 101 on the plane and six embedded portions 102 spaced at equal angles from the periphery of the plane to the side surfaces constitute the common portion. The remaining portions 103 on the plane and side surfaces constitute the group identifying portion. The group identifying portion has a color assigned to each group, while the common portion is white. The group identifying portion and the common portion can be viewed from any of the top, bottom, and side surfaces.

[0047] It should be noted that the game coin may also consist solely of a group-determining portion without a common portion. Furthermore, in this embodiment, the group-determining portion indicates the group by its color, but, as an alternative, the group-determining portion may be indicated by its pattern or even design. Furthermore, in this embodiment, the roulette game coins are a fixed amount, but game coins of various values ​​may be prepared for each group. In this case, for example, a number indicating the value may be indicated on the central circular portion 101, which serves as the common portion, and the color of the embedded portion 102 may be set to a different color from that of the portion 103, and the color of the embedded portion 102 may be used to indicate the value. Furthermore, the values ​​of the game coins of the same group may all be the same, while different fixed amounts may be set for different groups.

[0048] The dealer distributes different sets of game coins (thus, different specific colors) to different players. For example, when six players are allowed to play simultaneously at a roulette table, six specific colors of game coins are prepared for the table 10. Players who finish playing roulette and wish to leave the table return their used game coins to the dealer, thereby settling accounts. Settlement is performed using regular game coins or cash.

[0049] The game coin has an embedded RFID tag 104. The RFID tag 104 stores at least information identifying the group to which the game coin belongs. If game coins of multiple denominations are available, the RFID tag 104 also stores the denomination information. As mentioned above, since the color of the group identifying portion of the game coin varies for each group, the RFID tag 104 can store information identifying the color of the group identifying portion.

[0050] In this embodiment, the RFID tag 104 stores a game coin ID as information for determining the group to which the game coin belongs. In order to use the game coin ID to determine the group to which the game coin belongs, a game coin database (not shown) is prepared. The game coin database stores information on the group to which the game coin belongs (i.e., the color of the group determination unit of the game coin) according to each game coin ID. Thus, by determining the game coin ID and referring to the game coin database, the group of the game coin with the game coin ID can be determined.

[0051] It should be noted that the RFID tag 104 of the game coin stores information corresponding to the group of the game coin. By reading the RFID tag 104, the group to which the game coin belongs can be directly determined from the RFID tag 104 without preparing and referring to a database.

[0052] (RFID reading of game coins)

[0053] An antenna for reading the RFID tags 104 of gaming coins placed on the tabletop is embedded under the tabletop of the gaming table 10 . Figure 6 This figure shows an example of the antenna configuration in the gaming table of this embodiment. Multiple dealer chip area antennas 121 are provided in the dealer chip area 12. The reading ranges of adjacent dealer chip area antennas 121 overlap, so that the entire dealer chip area 12 is covered by the reading range of any one dealer chip area antenna 121.

[0054] Storage area 13 is also equipped with multiple storage area antennas 131. The read ranges of adjacent storage area antennas 131 overlap, so that the entire storage area 13 is covered by the read range of any storage area antenna 131. A shielding member 141 is provided between the dealer coin area 12 and storage area 13. This prevents the dealer coin area antenna 121 in the dealer coin area 12 from reading the RFID tags of coins in the storage coin area 13, and also prevents the storage area antenna 131 in the storage coin area 13 from reading the RFID tags of coins in the dealer coin area 12.

[0055] (Photographing of the placement area)

[0056] As described above, the first camera 14, the second camera 15, and the third camera 16 all capture the placement area 13 from obliquely above. Thus, a stack of tokens stacked and placed in the placement area 13 is captured from obliquely above.

[0057] Figure 71 is a diagram showing an example of a game coin stack shot by a camera in this embodiment. The first camera 14, the second camera 15, and the third camera 16 shoot the game coin stack from obliquely above, so that Figure 7 As shown, the captured image shows the upper surface of the uppermost game coin in the game coin stack and the side surfaces of all the game coins in the game coin stack.

[0058] As mentioned above, since the side of the game coin has at least a group determination portion, if Figure 7 As shown, if a pile of game coins is photographed, the group identification parts of all the game coins included in the pile of game coins will be displayed in the image.

[0059] (Roulette Game Process)

[0060] In roulette, the dealer first allows players to place bets and places the ball onto the spinning wheel 11. While the ball spins around the edge of the wheel 11 due to centrifugal force, players can still place bets. Once the centrifugal force weakens, the dealer places their hand down on the betting area 13 and calls out, "No more bets." This call prohibits players from making new bets or changing their bets, thus confirming their bets.

[0061] If the ball falls into the roulette wheel 11 and enters any pocket of 0, 00, 1 to 36 of the rotating roulette wheel 11, the game result is determined. The dealer places a marker (Dolly) on the placement object corresponding to the pocket into which the ball falls. In the case where a game coin is placed on the placement object, a marker is placed on such a game coin. Afterwards, the dealer will recycle the non-elected placed game coins (hereinafter referred to as "non-elected game coins") in the game, that is, the game coins that the dealer should recycle, to the dealer game coin area 12 according to the game result. Afterwards, for the placed game coins (hereinafter referred to as "elected game coins") that were selected in the game, the game coins are taken out from the dealer game coin area 12 and apportioned (paid). At this time, for the elected game coins, the number (or even the amount) of game coins of the same type as the elected game coins are paid according to the apportionment multiplier.

[0062] If the player receives the selected game coin and the paid game coin, the process of the game ends and the placement of the next game begins. The dealer starts the rotation of the roulette wheel 11 to carry out the next game and puts the ball into the roulette wheel 11. Thereafter, these steps are repeated to repeatedly carry out the game.

[0063] (System Structure)

[0064] Figure 8This is a block diagram illustrating the configuration of a management system according to this embodiment. The management system 100 manages roulette games played using roulette tokens on a roulette table 10. The roulette table 10 includes a roulette wheel 11 and a placement area 13 divided into a plurality of placement areas. The management system 100 includes a first camera 14, a second camera 15, and a third camera 16, each of which captures and generates images of the placement area 13 from different, obliquely upward positions.

[0065] The analysis device 110 analyzes the images captured by the first camera 14, the second camera 15, and the third camera 16 to identify the number of roulette coins of each color placed in the placement area 13, the multiple boundaries of the adjacent placement target areas, and furthermore, to determine the positional relationship between the identified roulette coins and the identified boundaries. In particular, the analysis device 110 analyzes images captured of winning coins remaining in the placement area 13 after the dealer has collected the unwinning coins.

[0066] The analysis device 110 uses machine learning or deep learning to analyze images. To this end, the analysis device 110 uses images obtained by photographing a stack of game coins placed on the placement area 13 for learning. To prepare images for learning, the stack of game coins is photographed under various conditions. In addition, a learning image is prepared for each of the multiple groups, and a learning image is also prepared for each number of game coins included in the stack. Furthermore, images of game coins neatly stacked in the stack and images stacked staggered from each other are prepared as learning images. Furthermore, images with darker lighting, brighter lighting, and images with lighting having a specific hue are also prepared as learning images. The analysis device 110, having learned such learning images, can robustly perform image recognition under various conditions.

[0067] When adjacent placement object areas are divided by a boundary line, the parsing device 110 can learn the boundary line as a recognition target. When the placement object areas are divided by painting each placement object area with a predetermined color, and by painting adjacent placement object areas with different colors, the parsing device 110 can identify the boundary between these placement object areas by identifying each placement object area. Furthermore, based on the coordinates of the gaming coin identified by the first camera 14, the second camera 15, and the third camera 16, it can be identified that the gaming coin is located on the boundary line. In this case, the boundary line is mapped into the coordinates.

[0068] Furthermore, the management system 100 includes: a plurality of placement area antennas 131, which are built into the placement area 13 and are used to read the RFID tags of roulette game coins placed in the placement area 13; and a placement area reader 130, which is used to control the plurality of placement area antennas 131. The management system 100 also includes: a plurality of dealer game coin area antennas 121, which are built into the dealer game coin area 12 and are used to read the RFID tags 104 of roulette game coins placed in the dealer game coin area 12; and a dealer game coin area reader 120, which is used to control the plurality of dealer game coin area antennas 121.

[0069] The placement area reader 130 and the dealer coin area reader 120 drive their corresponding antennas to read the information on the RFID tags 104 of the coins within their respective reading ranges. As described above, in this embodiment, because multiple antennas are arranged in the placement area 13 and dealer coin area 12 with overlapping reading ranges, the coin ID stored on the RFID tag 104 of a single coin may be read repeatedly by two or more antennas. The placement area reader 130 and the dealer coin area reader 120 combine the coin IDs repeatedly read by the multiple antennas into a single one and determine that a single coin with that coin ID exists.

[0070] The control device 140 controls the first camera 14, the second camera 15, and the third camera 16, and the analysis device 110, and controls the plurality of placement area antennas 131 via the placement area reader 130, thereby performing dealer-assisted payment processing. During the dealer-assisted processing, the control device 140 guides the dealer on the number (or even the amount) of payout coins to be paid for each selected coin.

[0071] As a result of the dealer assistance process, the control device 140 generates a dealer assistance screen indicating dealer assistance content, and the display 17 displays the dealer assistance screen.

[0072] (Dealer Assisted Processing)

[0073] The following describes the player-assisted processing in detail. As described above, if the game result is determined due to the ball entering any pocket on the roulette wheel 11, the dealer first recycles the non-selected game coins from the storage area 13 to the dealer game coin area 12. At this time, the control device 140 controls the storage area reader 130, thereby utilizing multiple storage area antennas 131 to read the RFID tags of the selected game coins remaining in the storage area 13 and obtain a reading result including the number of each color of the selected game coins (hereinafter referred to as the "first reading result").

[0074] In addition, at this time, the control device 140 controls the analysis device 110 to analyze the images captured by the first camera 14, the second camera 15 and the third camera 16 respectively (hereinafter, these images are referred to as "first images"), and determines the number of each color (group) of selected game coins placed across the boundary of the placement object area (hereinafter referred to as "boundary selected game coins"), and obtains it as the first image analysis result.

[0075] Figure 9 It is a diagram showing a display example of a dealer assistance screen showing the result of the dealer assistance process. Figure 9 Shows that Figure 4 In the case of placement shown in FIG. 1 , the dealer auxiliary screen is displayed when the game result is “No. 20” (the ball enters pocket No. 20 on the roulette wheel 11). Figure 9 As shown, for the selected game coins, the dealer auxiliary screen 171 includes information on the group to which the selected game coins belong (i.e., the color of the selected game coins), the number of selected game coins (and even the amount of selected game coins), and the number of shares (and even the share amount) according to various categories of placement methods (i.e., winners).

[0076] like Figure 9 As shown, according to Figure 4 The game coins placed in the straight bet number 20, the split bet including number 20, and the corner bet including number 20 are the winning game coins. The number of coins allocated to these game coins is calculated according to the rule-based allocation ratio. By viewing the dealer assistance screen 171, the dealer knows how many coins of each color should be allocated to each winning game coin, allowing for quick and accurate payment operations.

[0077] In order to generate such a dealer auxiliary screen 171, the control device 140 must determine the placement method of the selected game coins, that is, in which placement target area and even at the boundary of the placement target area, how many and which groups of selected game coins are placed. Figure 4 In the example shown, the selected game coins are arranged around the placement target area "20" as the center. In this way, when the game coins are placed close to each other, it is difficult to understand that they are placed in different positions according to the game coin stacks by reading the RFID tag 104, and it is difficult to determine which game coin is placed where.

[0078] Figures 10-121 is a diagram showing examples of selected game coins displayed in the image of the first camera 14, the image of the second camera 15, and the image of the third camera, respectively, in this embodiment. In any one of the images of the first camera 14, the image of the second camera 15, and the image of the third camera, a portion of the partial game coin stack located on the back side is obscured (occlusion) by other game coin stacks on the front side when viewed from the camera. In image analysis, it is not easy to accurately identify the type and number of each game coin in the partial game coin stack located on the back side like this. In particular, for images like Figure 4 In the example of the game coin "No. 20" being directly selected, the selected game coin surrounded by other selected game coins will be partially blocked in any of the images of the first camera 14, the second camera 15 and the third camera due to the pile of game coins in front.

[0079] Therefore, in this embodiment, as the selected coin, a coin for accurately identifying a coin stack that is partially hidden by other coin stacks is used.

[0080] The control device 140 first determines the number of each color of the selected game coins (hereinafter referred to as "image-identifiable selected game coins") that are not blocked in any first image and are identified through image analysis based on the analysis result of the first image of the analysis device 110. Figure 4 In the example, game coins C11 and game coins C15 are not blocked in the first image of the first camera 14, game coins C11 and game coins C12 are not blocked in the first image of the second camera 15, and game coins C14 are not blocked in the first image of the third camera 16. Therefore, all game coins except game coins C13 can be identified as image-recognizable selected game coins through image analysis.

[0081] On the other hand, the game coin C13 is a selected game coin that is blocked in the first image of any one of the first camera 14, the second camera 15, and the third camera 16 (hereinafter referred to as the "blocked selected game coin"). Therefore, for such a blocked selected game coin, the control device 140 subtracts the number of image-identifiable selected game coins of each color identified by image analysis from the number of selected game coins of each color indicated by the first reading result of the RFID tag 104, thereby determining the number of each color of the blocked selected game coins.

[0082] Furthermore, the control device 140 determines the position of the shielded selected game coin based on the positions of all image-identifiable selected game coins. Figure 4In the example case, the split bets of 17-20, the corner bets of 17-18-20-21, the corner bets of 20-21-23-24, and the split bets of 19-20 are image-recognized as described above, and therefore, the control device 140 determines that the obscured selected game coins are the direct selection of "20" that is obscured by these game coins.

[0083] Thus, for the selected game coin, the control device 140 uses the first reading result obtained by reading the RFID tag and the analysis result of the first image to determine the placement method (and even the placement object) and the number of coins of each color, including the selected game coin that obscures the selected game coin. Furthermore, for the determined number of coins of each color, the control device 140 calculates the allocated number of coins of each color based on the allocation multiplier corresponding to the respective placement method, and generates the dealer assistance screen 171 including the allocated number of coins of each color. It should be noted that, similar to the game coins placed on the boundary of the inner placement area, the first reading result obtained by reading the RFID tag and the analysis result of the first image are also used to determine the placement method (and even the placement object) and the number of coins of each color, including the selected game coin that obscures the selected game coin.

[0084] Furthermore, in the above-described embodiment, the game coin IDs repeatedly read by the multiple placement area antennas 131 in the placement area 13 are unified into one, and the presence of a game coin having the game coin ID in the placement area 13 is determined. Alternatively, the game coin IDs can be read by separating the inner placement area from the outer placement area, thereby separately obtaining the game coin IDs of the game coin placed in the inner placement area and the game coin IDs of the game coin placed in the outer placement area. It should be noted that, in some cases, depending on the position of the placed game coin, the game coin placed in the inner placement area can be read by the placement area antenna 131 in the inner placement area, and can also be read by the placement area antenna 131 in the outer placement area. Furthermore, the reverse is also possible. Even in this case, the signal strength can be used to determine whether the game coin is placed in the inner placement area or the outer placement area.

[0085] (Alert for recycling and payment fraud)

[0086] The management system 100 of this embodiment also has the function of outputting an alarm in the event of cheating during the recycling of non-selected game coins. To this end, the control device 140 controls the placement area reader 130 at the moment when the player's placement is completed, and uses the placement area antenna 131 to read the RFID tags 104 of all placed game coins placed in the placement area 13, and obtains the read result (hereinafter referred to as the "second read result"). In addition, before recycling, the control device 140 uses the dealer game coin area antenna 121 to read the RFID tags 104 of all game coins in the dealer game coin area 12, and obtains the read result (hereinafter referred to as the "third read result").

[0087] If the game outcome is determined and the dealer reclaims the non-elected tokens from the placement area 13 to the dealer token area 12, the control device 140 controls the dealer token area reader 120 to use the dealer token area antenna 121 to read the RFID tags 104 of all tokens in the dealer token area 12, including the reclaimed non-elected token, and obtain a read result (hereinafter referred to as the "fourth read result"). Furthermore, the control device 140 calculates the number of tokens of each color added to the dealer token area 12 due to the reclaim by obtaining the difference between the third read result and the fourth read result. Conversely, the control device 140 calculates the number of tokens of each color added to the dealer token area 12 due to the reclaim by obtaining the difference between the first read result, obtained by reading only the elected tokens in the placement area 13, and the second read result, obtained by reading all placed tokens.

[0088] The control device 140 determines whether the increase in the dealer's coin area 12 due to the recycling obtained in this manner is consistent with the decrease in the coin placement area 13 due to the recycling. If they are inconsistent, an alarm is output. The alarm is output as a visual message via the display 17.

[0089] It should be noted that in this embodiment, the number of each color of non-selected game coins returned to the dealer game coin area 12 is determined based on the difference in the reading results of the dealer game coin area 12 before and after the return. Specifically, the dealer game coin antenna 121 provided in the dealer game coin area 12 is used as a return game coin antenna for reading the RFID tags 104 of the returned non-selected game coins. However, a dedicated return game coin antenna that only reads the RFID tags 104 of the returned non-selected game coins may alternatively be used. In this case, the returned non-selected game coins are returned to the area provided with the dedicated return game coin antenna and read. The returned non-selected game coins are then moved to the dealer game coin area 12.

[0090] In addition, for payment, cheating detection is also carried out in the same manner. That is, the management system 100 of this embodiment has the function of outputting an alarm when there is cheating in the payment of the selected game coins. For this reason, the control device 140 reads the RFID tags 104 of all the game coins in the dealer game coin area 12 after the payment is completed, and obtains the reading result (hereinafter referred to as the "fifth reading result"). Furthermore, the control device 140 calculates the number of each color of the game coins reduced in the dealer game coin area 12 due to payment by obtaining the fourth reading result of the RFID tags 104 of all the game coins in the dealer game coin area 12 after the recovery is completed and the difference between the fifth reading result of the RFID tags 104 of all the game coins in the dealer game coin area 12 after the payment is completed.

[0091] In addition, the control device 140 reads the RFID tags 104 of all the game coins in the placement area after payment and obtains a reading result (hereinafter referred to as the "sixth reading result"). Furthermore, the control device 140 calculates the number of game coins of each color added to the placement area 13 due to payment by obtaining the difference between the sixth reading result of the RFID tags 104 of all the game coins in the placement area 13 after payment and the first reading result of the RFID tags 104 of all the game coins in the placement area 13 after collection.

[0092] The control device 140 determines whether the reduction amount of the game coins in the dealer game coin area 12 due to the payment obtained in this way is consistent with the increase amount of the game coins in the placement area 13 due to the payment, and outputs an alarm if it is inconsistent.

[0093] The cheating detection for payment mentioned above determines whether the reduction in the number of game coins in the dealer's game coin area 12 due to the payment is consistent with the increase in the number of game coins in the placement area 13 due to the payment, thereby confirming whether the game coins have been completely moved from the dealer's game coin area 12 to the placement coin area 13 during the payment. However, in this embodiment, as described above, the placement method (and even the placement object) and the number of coins of each color are determined for the selected game coins. Furthermore, for the determined number of coins of each color of the selected game coins, the allocated number of coins of each color is calculated based on the allocation multiplier corresponding to the respective placement method. Therefore, the control device 140 determines whether the actual number of game coins in the placement area 13 due to the payment has increased according to the calculated allocated number of coins of each color. The increase in the number of game coins in the placement area 13 due to the payment can be obtained by obtaining the difference between the sixth reading result and the first reading result as described above.

[0094] On this basis or as an alternative thereto, the control device 140 may determine whether the number of game coins in the dealer game coin area 12 has decreased based on the calculated number of coins allocated to each color. The amount of game coins decreased due to the payout in the dealer game coin area 12 can be obtained by obtaining the difference between the fourth reading result and the fifth reading result as described above.

[0095] Furthermore, to detect payout cheating, a dedicated payout coin antenna can be used to read coins removed from the dealer's coin area 12 and placed in front of the placement area 13. In this case, payout coins paid into the placement area 13 are read after being returned to the area equipped with the dedicated payout coin antenna. The payout coin is then moved by the dealer to the vicinity of the corresponding selected coin in the placement area 13.

[0096] When a dedicated payout coin antenna is used, to detect payout fraud, the control device 140 can determine whether the number of coins of each color reduced by a payout in the dealer coin area 12 is consistent with the number of coins of each color read by the dedicated payout coin antenna. Alternatively, or in addition to this, to detect payout fraud, the control device 140 can determine whether the number of coins of each color read by the dedicated payout coin antenna is consistent with the number of coins of each color added by the payout in the placement area 13. Furthermore, when a dedicated payout coin antenna is used, the control device 140 can determine whether the calculated apportioned number of coins of each color is consistent with the number of coins of each color read by the dedicated payout coin antenna.

[0097] (Customer Rating)

[0098] The management system 100 of this embodiment also has the function of performing customer rating. In order to achieve this function, Figure 8 As shown, the management system 100 includes a card reader 160 and a player database 170. The card reader 160 scans the membership card of a player who wishes to purchase roulette tokens to obtain information identifying the player (player ID). The control device 140 associates the acquired player ID with the information regarding the set (color) of roulette tokens assigned to the player. This association can be performed by the dealer using an input device (not shown) to the control device 140.

[0099] If the color of the game coin is associated with the player ID, the control device 140 records each player's placed number of coins (amount placed) in the player database 170 based on the number of coins of each color placed, as indicated by the second read result, at the end of the placement. By performing this recording each time a game is played, the player database 170 maintains a historical record of the number of coins placed (amount placed) and the cumulative amount for each player. It should be noted that the player database 170 may only record either the historical record or the cumulative amount.

[0100] It should be noted that the player can be identified using a camera. In this case, the face of the player intending to purchase roulette tokens can be captured by a camera, and this image can be used for facial recognition to identify the player. In this case, any of the first camera 14, the second camera 15, or the third camera 16 can be used as a camera. Even in this case, the association between the identified player and the color of the roulette token can be performed by the dealer, or the camera can be used for this association. Specifically, a camera can capture the player placing the roulette token and analyze the image to identify the player, identify the token, and associate the player with the token's color.

[0101] (Variation)

[0102] In the above-mentioned embodiment, the first camera 14, the second camera 15, and the third camera 16 all shoot and generate images at specified times, and the analysis device 110 analyzes the shot images. However, as an alternative, the first camera 14, the second camera 15, and the third camera 16 can shoot images, and the analysis device 110 analyzes the shot images or analyzes images extracted from the images.

[0103] In the above embodiment, the game table 10 is equipped with three cameras, including a first camera 14, a second camera 15, and a third camera 16. However, at least two cameras are sufficient. When two cameras are used, it is desirable that the two cameras be positioned at opposite corners of the placement area 13, as in the positional relationship between the first camera 14 and the third camera 16 in the above embodiment. Furthermore, four or more cameras may be provided. It should be noted that when four cameras are provided, the four cameras may be positioned at the four corners of the game table 10. Furthermore, the multiple cameras may differ from each other in terms of installation height, viewing angle, resolution, and other aspects, in addition to their installation positions and shooting directions.

[0104] In the above-described embodiment, multiple placement area antennas 131 are arranged in an overlapping manner in the placement area 13. When the placement area reader 130 uses multiple placement area antennas 131 to read the same game coin ID, these are unified and processed as the game coin ID of a single game coin. For each game coin, the control device 140 can be configured to determine the approximate location of the game coin based on the strength of the signal received from the RFID tag by each placement area antenna 131. Similarly, for the dealer coin area 12, the location of the game coin can be determined based on the strength of the signal received from the RFID tag by the multiple dealer coin area antennas 121.

[0105] In the above embodiment, roulette coins used exclusively for roulette are used as an example. However, regular roulette coins with embedded RFID tags can be used for placement and clearing according to prescribed rules (for example, when the number of players participating in the roulette game is small and the dealer permits this). Even in this case, the antennas and readers of the management system 100 can read the RFID tags of regular roulette coins and perform the same management as described above.
