Abstract
A fraud detection system which detects fraud in a game of performing collection and redemption of chips in accordance with a win or lose result includes a camera which captures an image of chips contained in a chip tray of a dealer, an image analyzing apparatus which analyses the image captured by the camera to detect an amount of the chips contained in the chip tray, a card distribution device which determines a win or lose result of a game, and a control device which compares the win or lose result of the game and the amount of the chips contained in the chip tray before and after collection and redemption of the chips to detect fraud.
Claims (18)
1. A chip recognition system for recognizing chips to be used at a gaming table in an amusement facility, the chip recognition system comprising:
a capturing device configured to capture an image of chips by a camera, wherein each of the chips is configured to include at least one specific color indicating a value of the chip; and
a recognition device configured to apply artificial intelligence to the captured image and identify the specific color of a chip of the chips to recognize the value of the chip, wherein the artificial intelligence is trained to identify the specific color of the chip regardless of capturing conditions that make it difficult to distinguish the specific color of the chip.
2. The chip recognition system according to claim 1 , wherein the capturing conditions include a condition where the chips enter into a shadow.
3. The chip recognition system according to claim 1 , wherein the chip has at least the specific color indicating the value of the chip at a predetermined location or in a predetermined shape.
4. The chip recognition system according to claim 1 , wherein the recognition device is further configured to identify a number of chips based on identification of the specific color of the chip.
5. The chip recognition system according to claim 1 , wherein the recognition device further is configured to identify a number of chips for each specific color of a plurality of specific colors by identifying, for each chip of a plurality of the chips, the specific color.
6. The chip recognition system according to claim 1 , wherein the artificial intelligence used by the recognition device is an artificial intelligence trained with a plurality of images including images captured under various capturing conditions.
7. The chip recognition system according to claim 1 , wherein the recognition device is configured to:
determine the specific color of a plurality of chips stacked on top of each other, and
determine the specific color or number of chips when the chips are partially hidden due to a blind spot of the camera.
8. The chip recognition system according to claim 1 , wherein the recognition device is configured to determine position of the chips.
9. The chip recognition system according to claim 1 , wherein
the capturing device is set diagonally above the gaming table to capture the image of a plurality of chips stacked on top of each other diagonally above,
at least part of a side surface of the chip is shown in the image, and
the recognition device is configured to recognize the value of the chip using deep learning technology as the artificial intelligence.
10. The chip recognition system according to claim 1 , wherein the chip recognition system has a plurality of the capturing device.
11. The chip recognition system according to claim 1 , wherein the recognition device is configured to recognize the value of the chip even if the chips are stacked on top of each other in a way that does not align with each other.
