Abstract

The present invention addresses the issue of image analysis technology being unable to determine whether or not a dealer has accurately performed redemption, during redemption of substitute currency for gaming (chips) corresponding to wagered chips, and the issue of being unable to sufficiently prevent mistakes, as a result of the design of the chips on a gaming table being complicated. This detection system comprises a control device (9) that detects unfair practices at a gaming table (1), using image analysis results from an image analysis device (6). A substitute currency for gaming, used in this detection system, has a multi-layer structure having laminated therein a plurality of different colored plastic layers, comprising a colored layer in at least the middle thereof, and having laminated therein, on both sides of the middle colored layer, a white layer or a light-color layer (not shown in the drawing but can be a layer of any color lighter than the colored layer). In this way, the substitute currency for gaming has a multi-layer structure comprising a colored layer and has laminated on both sides of this middle colored layer a white layer or a light-color layer (not shown in the drawing but can be a layer of any color lighter than the colored layer). The camera (4) also captures an image of a plurality of stacks of game tokens placed in a plurality of bet areas set on a game table from above at an angle so that the plurality of stacks are shown in the depth direction. Also, the management control device (9) is equipped with a function of performing a deep learning image recognition to the image to determine the number or type of the gaming token in the plurality of stacks.

Claims

1. A table game management system that manages game tokens on a game table, wherein the game token has an RFID that stores information of a type of the game token, and has, in appearance, on a side face of the game token, a layer characterized by a first surface color (101) different according to the type of the game token and a layer characterized by a second surface color (102) not depending on the type of the game token, the table game management system comprising: a camera (4) that captures an image of a plurality of stacks of game tokens (100) placed in a plurality of bet areas (24) set on a game table (1) from above at an angle so that the plurality of stacks are shown in the depth direction; and a management control device (9) that is equipped with a function of performing a deep learning image recognition to the image to determine the number or type of the gaming token in the plurality of stacks.

2. The table game management system according to claim 1, wherein the management control device is equipped with a function of performing a deep learning image recognition to the image to determine the type of the game token in the plurality of stacks.

3. The table game management system according to claim 1, wherein a pattern made up of the first surface color (101) and the second surface color (102) formed on the side face of the game token, and the management control device determines the type of the game token based on the first surface color.

4. The table game management system according to claim 3, wherein the first surface color is continuous in a circumferential direction.

5. The table game management system according to claim 3, wherein the second surface color is continuous in a circumferential direction.

6. The table game management system according to claim 3, wherein the side face of the game token has a portion whose surface color changes in a thickness direction. [
