[0042] The following describes a method for implementing the invention; however, the embodiments described below are merely examples, and the invention is not limited to the embodiments described below. Furthermore, the elements of the various embodiments can be combined arbitrarily.

[0043] Figure 1 This is a diagram showing a game table using a game monitoring system implemented according to an embodiment of the present invention. Figure 1 As shown, the game monitoring system 100 of this embodiment can be applied to game tables 110 in casinos, etc.

[0044] The game table 110 has a generally oval-shaped tabletop 111. The dealer is located on one side of the tabletop 111, and player positions are located on the opposite side, where multiple players can be positioned. Each player position has a designated placement area 112. In this embodiment, the game table 110 is a game table for a card game. The placement area 112 includes areas for placing players, dealers, ties, player pairs, and dealer pairs, serving as placement objects.

[0045] The game table 110 is equipped with a first camera 11 and a second camera 12. The first camera 11 is configured to capture the placement area 112, the game coins placed in the placement area 112, and the player playing the game on the game table 110. The second camera 12 is configured to capture the placement area 112 and the game coins placed in the placement area 112, and displays the game coins in a larger format than the first camera 11. The first camera 11 and the second camera 12 are mounted on poles 113 and 114 of the game table 110. It should be noted that multiple first cameras 11 and multiple second cameras 12 can be set up to distribute the shooting range.

For example... Figure 2 As shown, a center line 51 is provided in the center of the thickness direction on the side of the game coin 50. The color of the center line 51 indicates the type (value) of the game coin 50. Therefore, by observing the side of the game coin 50, the value of the game coin 50 can be determined by the color of the center line 51.

[0047] The center line 51 is provided with code information for identifying the game chip ID of the game chip 50.

[0048] As shown in FIG. 1, the game chip 50 is provided with a game chip ID 50a on the side surface. The game chip ID 50a is indicated by a code provided on the center line 51 of the game chip 50. The code is indicated by the presence or absence of a plurality of dots arranged in two rows. That is, binary information is expressed by the presence or absence of a dot in each column, and 5 bytes of information are expressed by a dot matrix of 20 columns. Note that the plurality of dots indicating the game chip ID can be printed on the side surface of the game chip 50 using ink that is not visually confirmed under natural light but visualized by irradiation of infrared or ultraviolet light. Figure 3 As shown in FIG. 1, the game chip 50 is provided with a game chip ID 50a on the side surface. The game chip ID 50a is indicated by a code provided on the center line 51 of the game chip 50. The code is indicated by the presence or absence of a plurality of dots arranged in two rows. That is, binary information is expressed by the presence or absence of a dot in each column, and 5 bytes of information are expressed by a dot matrix of 20 columns. Note that the plurality of dots indicating the game chip ID can be printed on the side surface of the game chip 50 using ink that is not visually confirmed under natural light but visualized by irradiation of infrared or ultraviolet light.

[0049] Figure 4 is a block diagram showing the configuration of the game monitoring system according to the present embodiment. The game monitoring system 100 is provided with an information processing device 20 and a database 40 in addition to the first camera 11 and the second camera 12 described above. The first camera 11 and the second camera 12 are communicably connected to the information processing device 20, respectively. Further, the information processing device 20 is communicably connected to the database 40.

[0050] The information processing device 20 can be provided for each game table 110, or the first camera 11 and the second camera 12 provided for a plurality of game tables 110 can be connected to one information processing device 20, respectively. Further, the database 40 can be provided for each game table 110, or one database 40 can be provided for a plurality of game tables 110. Further, the database 40 can be provided on the cloud.

[0051] The first camera 11 and the second camera 12 respectively perform imaging at the time when the player places the game chip 50 on the placement area 112 of the game table 110, or at the time when the game chip 50 is placed on the placement area 112 and the game is started (i.e., at the time when the game chip 50 is not allowed to be moved thereafter).

[0052] The information processing device 20 is a computer composed of a storage device serving as a temporary storage area, a processor that performs calculation corresponding to an input signal according to the information processing program of the present embodiment, and a storage device in which various data are stored. The database 40 is provided with a storage device and a processing device that performs processing such as search and update of information stored in the storage device.

[0053] The information processing device 20 has a function of identifying the game chip ID of the game chip 50 by executing the information processing program of the present embodiment. Figure 4The information processing apparatus 20 is provided with various functions as shown. Specifically, the information processing apparatus 20 is provided with a chip detection section 21, a chip ID determination section 22, a player detection section 23, a player ID determination section 24, a first association section 25, a second association section 26, a comparison section 27, a recording section 28, an overwriting control section 29, and an updating section 30.

[0054] The chip detection section 21 acquires an image (hereinafter, referred to as "first image") taken by the first camera 11, and detects a chip set region including a chip set from the first image. In a case where the chips 50 placed on the placement region 112 of the game table 110 are stacked and placed on the placement region 112, the chip detection section 21 detects a region including the stack of the placed chips as a chip set region (chip stack region). Specifically, the chip detection section 21 detects a rectangular frame including a chip set as a chip set region.

[0055] The chip detection section 21 detects a chip region corresponding to each chip from the detected chip set region. At this time, the chip detection section 21 can detect each chip region using the center line 51 of the side surface of the chip 50. That is, the chip detection section 21 can determine the position and size of the chip region from the position and length of the center line 51.

[0056] The chip ID determination section 22 acquires an image (hereinafter, referred to as "second image") taken by the second camera 12. Also, the chip ID determination section 22 detects a chip set region and a chip region from the second image in the same manner as the chip detection section 21. The chip ID determination section 22 performs code recognition on the detected chip region, and interprets the code information of each chip 50. Thereby, the chip ID determination section 22 determines the chip ID of each chip region, and in this way, determines all chip IDs included in each chip set region. At this time, the chip ID determination section 22 can detect the center line 51 of the chip 50, and further perform code recognition in the region of the detected center line 51.

[0057] Alternatively, the chip ID determination section 22 can be an RFID system that determines the chip ID of the chip placed on the placement region 112 by RFID. In this case, the chip is provided with an RFID tag that stores the chip ID of the chip. The RFID system is provided with an antenna and a reader. The antenna is buried under the table top 111 at a position corresponding to each placement region 112. The reader is connected to the antenna, and acquires the chip ID from a signal read by the antenna.

[0058] The chip detection section 21 determines the position of the detected chip group area and determines the time at which the chip group area is detected. On this basis or as an alternative thereto, the chip ID determination section 22 determines the position of the chip 50 for which the chip ID has been determined on the game table. Further, the chip ID determination section 22 determines the time at which the chip 50 for which the chip ID has been determined is placed on the game table.

[0059] The player detection section 23 detects a player from the first image obtained by the photographing by the first camera 11. At this time, the player detection section 23 detects the entirety of the player including the face, the upper body, the wrist, and the hand as the player from the first image, and extracts a skeletal model constituted by the face area of the player, and each of the key points of the upper body, the wrist, and the hand. The player detection section 23 recognizes the face area and the skeletal model of the same player, or even the plurality of key points constituting the skeletal model, as belonging to one player.

[0060] The player ID determination section 24 determines the player ID by performing face authentication on the face area of the first image detected by the player detection section 23. The player determined by the player ID determination section 24 is registered in advance with the image of the face and is given a player ID, and the player ID determination section 24 determines which registered player the face of the face area is by using a face authentication technique. Note that in the case where the result of the face authentication is not to determine which registered player, the player ID determination section 24 determines that the player of the face area, that is, the player displayed by the player area, is an unregistered player.

[0061] The player can be registered by the player ID or by the face information. In the case where the player is registered by the player ID, the player ID determination section 24 determines the player ID of the player whose face area is detected from the first image. In the case where the player is registered by the face information, the player ID determination section 24 determines the face information of the player whose face image is detected from the first image. Here, the face information can be the face image of the player or can be a feature quantity extracted from the face image of the player.

[0062] The first association section 25 associates the first chip detected by the chip detection section 21 with the player detected by the player detection section 23 as the player who placed the first chip. Specifically, the first association section 25 associates the player detected by the player detection section 23 and the chip 50 detected by the chip detection section 21 based on the positional relationship between the hand of the player and the chip 50.

[0063] Figure 5is a diagram of an example of association of the first association section of the embodiment. In this embodiment, the chip set area cl, c2 is detected by the chip detection section 21 and the player Pl, P2 is detected by the player detection section 23 from the same image such as the first image 90 captured by the first camera 11. The first association section 25 determines the combination of the hand and the chip set area, and further determines the combination of the player and the chip set area, based on the distance between the hand pl l, p21 of the player Pl, P2 detected by the player detection section 23 and the chip set area cl, c2.

[0064] In Figure 5 In this example, since the distance between the reference point cpl of the chip set area cl and the hand pl l of the player Pl is below the prescribed threshold value, the first association section 25 associates the chip set area cl with the player Pl. Also, since the distance between the reference point cp2 of the chip set area c2 and the hand p21 of the player P2 is below the prescribed threshold value, the first association section 25 associates the chip set area c2 with the player P2. Note that the reference point can be the center of the lower edge of the rectangular frame constituting the chip set area.

[0065] As described above, since the player detection section 23 recognizes the face area fl, f2 and the skeleton model sm l, sm2 including a plurality of key points of the same player as belonging to the same player, the first association section 25 can associate the chip set area with the face area and the skeleton model, and even each key point.

[0066] The second association section 26 associates the chip ID of the chip 50 determined by the chip ID determination section 22 with the player associated with the chip 50 by the first association section 25. Specifically, the second association section 26 first identifies the chip 50 detected by the chip detection section 21 and the chip 50 detected by the chip ID determination section 22 and determined to have the chip ID as the same chip. To this end, the second association section 26 determines the chip 50 located at the same position as the same chip 50 based on the relationship between the position of the chip 50 in the second image detected by the chip ID determination section 22 and the position of the chip 50 in the first image detected by the chip detection section 21.

[0067] More specifically, the second association section 26 determines the chip stack areas located at the same position as the same chip 50 by converting the position of the chip stack area detected by the chip detection section 21 in the first image into the position in the second image. Alternatively, the second association section 26 can determine the chip stack areas located at the same position as the same chip 50 by converting the position of the chip stack area detected by the chip ID determination section 22 in the second image into the position in the first image. Alternatively, the second association section 26 can determine the chip stack areas located at the same position as the same chip 50 by converting into a coordinate space common to the position of the chip stack area detected by the chip detection section 21 in the first image and the position of the chip stack area detected by the chip ID determination section 22 in the second image.

[0068] In this way, the second association section 26 determines the chips 50 located at the same position as the same chip 50 based on the position determined by the chip detection section 21 and the position determined by the chip ID determination section 22, but can instead determine the chips 50 placed on the game table 110 at the same time as the same chip 50 based on the time at which the chip detection section 21 detects the chip and the time at which the chip ID determination section 22 determines the chip 50.

[0069] The second association section 26 associates the chip ID of the chip determined by the chip ID determination section 22 with the player associated with the chip by the first association section 25. More specifically, in the case where the player is registered by the player ID, the second association section 26 associates the chip ID of the chip determined by the chip ID determination section 22 with the player ID of the player associated with the chip by the first association section 25. Further, in the case where the player is registered by the facial information, the second association section 26 associates the chip ID of the chip determined by the chip ID determination section 22 with the facial information of the player associated with the chip by the first association section 25.

[0070] The recording section 28 records the combination of the chip ID of the chip 50 and the image of the player associated with the chip ID of the chip 50 by the second association section 26. At this time, as described later, the recording section 28 can also record the chip ID and the player ID of the player associated therewith, or can record the chip ID and the facial information of the player associated therewith. As in this embodiment, the recording section 28 records only the image of the player in association with the chip ID determined by the chip ID determination section 22, without recording the player ID used to determine the player associated with the chip ID, thereby not recording the personal information of the player, protecting the privacy of the player.

[0071] The game chip ID of the game chip 50 is stored in association with the owner of the game chip 50 in the database 40. Specifically, in the case where the player is registered by the player ID, the database 40 stores the game chip ID of the game chip 50 in association with the player ID of the player who is the owner of the game chip 50. Alternatively, in the case where the player is registered by the facial information, the database 40 stores the game chip ID of the game chip 50 in association with the facial information of the player who is the owner of the game chip 50.

[0072] The comparison section 27 compares the owner associated with the game chip ID of the game chip 50 in the database 40 and the player associated with the game chip ID of the game chip 50 by the second association section 26. When the owner associated with the game chip ID of the game chip 50 in the database 40 and the player associated with the game chip ID of the game chip 50 by the second association section 26 are not coincident, the comparison section 27 outputs a signal indicating the non-coincidence.

[0073] Specifically, in the case where the player is registered by the player ID, the comparison section 27 compares the player ID associated with the game chip ID of the game chip 50 in the database 40 and the player ID determined by the second association section 26 from the player associated with the game chip ID of the game chip 50. In this case, when the player ID of the owner associated with the game chip ID of the game chip 50 in the database 40 and the player ID of the player associated with the game chip ID of the game chip 50 by the second association section 26 are not coincident, the comparison section 27 outputs a signal indicating the non-coincidence.

[0074] In the case where the game chip ID of the game chip 50 is stored in association with the facial information of the owner of the game chip 50 in the database 40, on the basis of the above-described specific example or instead of the above-described specific example, the comparison section 27 compares the facial information associated with the game chip ID of the game chip 50 in the database 40 and the facial information extracted from the image of the player associated with the game chip 50 by the second association section 26. In this case, when the facial information associated with the game chip ID of the game chip 50 in the database 40 and the facial information extracted from the image of the player associated with the game chip 50 by the second association section 26 are not coincident, the comparison section 27 outputs a signal indicating the non-coincidence.

[0075] In the case of the game chip 50 on the game table 110, when the player different from the original owner operates the game chip 50, the signal indicating the non-coincidence can be output by the above-described function of the comparison section 27, and further, the non-coincidence can be warned.

[0076] In a case where the comparison section 27 determines that the owner associated with the chip ID of the chip 50 in the database 40 and the player associated with the chip ID of the chip 50 by the second association section 26 are not coincident, the rewriting control section 29 rewrites the owner associated with the chip ID of the chip 50 in the database 40 to the player associated with the chip ID of the chip 50 by the second association section 26.

[0077] In a case where the chip 50 is erroneously associated with a player, by the rewriting control section 29, the situation can be corrected and the association with the correct player can be established. Further, in a case where it is determined that the chip ID is not associated with any player, the rewriting control section 29 rewrites the player associated with the chip ID by the second association section 26 to the owner of the chip ID.

[0078] In a case where the player wins the game and receives the payment of the chip 50 from the dealer, the owner of the chip involved in the payment (hereinafter, referred to as "payment chip") should be changed from the dealer or the casino to the player who won the game. Therefore, the updating section 30 rewrites the owner associated with the chip ID of the payment chip paid by the dealer in the database 40 to the player associated with the payment chip by the second association section 26. To this end, the first camera 11 and the second camera 12 take a picture when the payment chip 50 is paid, the first association section 25 associates the chip group region of the payment chip with the player who wants to take the payment chip, and the updating section 30 updates the database 40 according to the association.

[0079] Alternatively, the updating section 30 rewrites the owner associated with the chip ID of the payment chip paid by the dealer in the database 40 to the player associated with the chip 50 moved out of the placement region 112 together with the payment chip by the second association section 26. Thereby, the chip ID of the payment chip 50 is stored in the database 40 in association with the player ID of the player who received the chip 50.

[0080] It is to be noted that the chip 50 has an RFID tag in which the chip ID is stored, and in a case where the chip ID determination section 22 reads the chip ID from the RFID tag of the chip 50 in the placement region 112, the chip ID of the payment chip can be determined by reading the RFID tag of the payment chip in the payment placement region 112, and the player ID to be associated with the chip ID can be updated.

[0081] Further, in the above-described embodiment, the first camera that generates the first image by imaging and the second camera that generates the second image by imaging are different cameras, but these can also be one camera. In this case, the first image and the second image can both be generated by the one camera. Also, in this case, the imaging conditions (angle of view, resolution, imaging direction, etc.) can be changed in the case of imaging the first image and in the case of imaging the second image.

[0082] As described above, in the game monitoring system 100 of the present embodiment, the first association unit 25 associates the chips 50 (chip stacks) on the game table 110 detected by the chip detection unit 21 from the first image with the players detected by the player detection unit 23 from the first image, the chip ID determination unit 22 determines the chip IDs of the chips 50 based on the second image, and the second association unit 26 associates the players with the chip IDs. Thus, it is possible to determine which player's chips 50 the chips 50 on the game table 110 are, and it is possible to perform cheating detection, customer rating, and the like.

[0083] Note that, as described above, the method of determining the chip IDs of the chips 50 on the game table 110 is not limited to the method using images, but can also be a method using an RFID tag and an RFID reading system. Since the chips and the players who handle the chips can be associated by the above-described embodiment, it is possible to determine which player placed the chips 50, for example, even in the case where the player placed the chips 50 in a placement area 112 other than the placement area in front of the player's own player position, or in the case of chips 50 placed by a rear placer who is not seated at a player position.

[0084] Note that, the information processing apparatus 20 can also recognize the positions, types, and numbers of the chips 50 placed on the game table 110 based on the first image or the second image, or by embedding a plurality of antennas in the game table 110 and reading the RFID tags of the chips 50 by embedding RFID tags that store at least information on the types of the chips 50 in the chips 50.
