Table game management system and game token
A detection system according to the present invention includes a control device that detects fraud conducted on a game table by using the image analysis result obtained by an image analysis device. In addition, each game token used in this detection system has a multilayer structure having plastic layers with a plurality of different colors stacked on each other, with a colored layer being provided at least intermediately, and white layers or light-colored layers (not illustrated, but may be any layers lighter in color than the colored layer) being stacked on two sides of the intermediate colored layer. As described above, this game token has a multi-layer structure including the colored layer, with the white layers or light-colored layers (not illustrated, but may be any layers lighter in color than the colored layer) being stacked on the two sides of the intermediate colored layer.
1. A system configured to determine a value of each of one or more game tokens that are put on a game table and constitute one or more stacks, wherein each game token has a notation of a value of the game token on a flat surface and has a first color part representing the value by a color thereof and a second color part not representing the value on a side surface, the system comprising:
a camera configured to capture an image of the one or more stacks that include the one or more game tokens put on the game table, the camera positioned diagonally above the game table to capture, for each stack of the one or more stacks, a top and a side of the stack; and
one or more processors configured to, using a deep learning technology:
analyze the image in which the one or more stacks appear; and
for each stack of the one or more stacks, determine, based on the analysis of the image:
a position of the stack placed in a betting area of a plurality of betting areas of the game table, the plurality of betting areas arranged in a depth direction with reference to a field of view of the camera; and
a total value of a set of one or more game token that constitute the stack captured in the image, the total value determined based on a number of game tokens included in the set of one or more game tokens of the stack and based on, for each token of the set of one or more game tokens, a value of the game token determined based on the first color part of the game token.
2. The system according to claim 1 , wherein the one or more processors is further configured to determine, based on the analysis of the image, a number of chip stacks of the one or more stacks bet on the game table.
3. The system according to claim 1 , wherein the one or more processors is configured to, for each stack of the one or more stacks, determine, based on the analysis of the image:
the number of game tokens included in the set of one or more game tokens of the stack; and
for each game token of the set of one or more tokens, the value of the game token based on the first color part of the game token.
4. The system according to claim 1 , wherein the one or more processors is further configured to, for at least one game token of the one or more game tokens, detect the first color part of the at least one game token from the image and determine the value of the at least one game token based on the color of the detected first color part.
5. The system according to claim 1 , wherein at least one game token of the one or more game tokens has a pattern in which at least a part of the first color part of the at least one game token is sandwiched by the second color part of the at least one game token on the side surface of the at least one game token.
6. The system according to claim 4 , wherein the one or more processors is further configured to determine a number of the one or more game tokens based on a number of the first color parts detected in the image.
7. The system according to claim 1 , wherein at least one game token of the set of one or more game tokens of the stack includes has information capable of identifying the value of the at least one game token, the information distinct from the first color part of the at least one game token, the system further comprising:
a reading device configured to read the information from the at least one game token,
wherein the one or more processors is further configured to inspect whether or not the value of the at least one game token read by the reading device matches the value of the at least one game token determined based on the first color part of the at least one game token.
8. The system according to claim 7 , wherein the information is stored in a RFID tag embedded in the at least one game token, and the reading device is a RFID reader.
9. The system according to claim 1 , wherein the plurality of betting areas are also arranged in a width direction with reference to the field of view of the camera.
10. The system according to claim 9 , wherein the one or more processors is further configured to determine, for each stack of the one or more stacks, the position of the stack in the depth direction, the width direction, or a combination thereof.
11. The system according to claim 1 , further comprising a plurality of cameras that include the camera, wherein a total number of cameras of the plurality of cameras is fewer than a total number of betting areas of the plurality of betting areas.
