Abstract

Claims (20)

1. A chip recognition system for a gaming table, the gaming table having a chip tray for holding one or more chips of a dealer and a table top surface on which chips are placed in a form of a chip stack, the chip recognition system comprising:

a camera configured to capture an image of the gaming table from diagonally above to capture a plurality of chip stacks placed on the gaming table, each of the plurality of chip stacks having a different distance from the camera, whereby the plurality of chip stacks appear in the image at different sizes;

at least one processor configured to:

perform an image analysis of the image using an artificial intelligence technology or deep learning technology to recognize the plurality of chip stacks that appear in the image, and

determine, respective numbers of chips of each of the recognized chip stacks; and

a chip ID reader configured to read chip IDs of the one or more chips held in the chip tray.

2. The chip recognition system according to claim 1 , wherein the at least one processor is further configured to determine, for each chip stack of the plurality of chip stacks, a position of the chip stack.

3. The chip recognition system according to claim 1 , wherein the at least one processor is further configured to recognize types of the chips in the plurality of chip stacks.

4. The chip recognition system according to claim 3 , wherein the at least one processor is further configured to determine an amount of each of the plurality of chip stacks based on the recognized types.

5. The chip recognition system according to claim 1 , wherein the chip ID reader is further configured to determine types of the one or more chips held in the chip tray based on the read chip IDs.

6. The chip recognition system according to claim 1 , wherein:

for each chip, the chip ID of the chip is read from an RFID of the chip, and

the chip ID reader is configured to read the one or more RFIDs of the one or more chips held in the chip tray.

7. The chip recognition system according to claim 1 , wherein the at least one processor is configured to perform the image analysis of the image which is captured according to a predetermined trigger by the camera.

8. The chip recognition system according to claim 1 , wherein the camera is configured to capture chips placed on the table top surface by the dealer.

9. The chip recognition system according to claim 1 , wherein the camera is configured to capture chips placed on the table top surface by a player.

10. The chip recognition system according to claim 1 , wherein the at least one processor is further configured to distinguish a chip stack placed by the dealer with a chip stack placed by a player.

11. The chip recognition system according to claim 1 , wherein the at least one processor is configured to recognize, by using the artificial intelligence technology, a chip stack even when a portion of the chip stack is hidden by a blind spot of the camera.

12. The chip recognition system according to claim 1 , wherein the at least one processor is configured to recognize, by using the artificial intelligence technology, a chip stack even when the chip stack consists of multiple chips stacked out of alignment with each other.

13. The chip recognition system according to claim 1 , further comprising a database configured to store information of the chips.
