Abstract

According to one embodiment, provided is a chip recognition system that recognizes a chip on a gaming table in an amusement place having the gaming table, the chip recognition system including: a game recording apparatus that records, as an image, a state of chips stacked on the gaming table, using a camera; an image analysis apparatus that performs an image analysis on the recorded image of the state of chips; a plurality of chip determination apparatuses including at least a first artificial intelligence apparatus that determines a number of the chips stacked, using an image analysis result obtained by the image analysis apparatus; and a second artificial intelligence apparatus that decides a correct number of the chips stacked, when the plurality of chip determination apparatuses obtain different determination results for the number of the chips stacked.

First claim

What is claimed is:

1 . A chip recognition system for a gaming table on which chips are stacked, the chip recognition system comprising:
a first game recording apparatus configured to capture a first image of the gaming table; a second game recording apparatus configured to capture a second image of the gaming table; and at least one processor configured to:
perform an image analysis of the first image using an artificial intelligence technology and an image analysis of the second image using an artificial intelligence technology;
determine, based on results of the respective image analyses, respective numbers and positions of the chips appeared in the first image and the second image; and
decide a number and a position of the chips stacked on the gaming table based on the respective numbers and positions of the chips determined by the image analyses of the first image and the second image.

2 . The chip recognition system according to claim 1 , wherein the number and the position of the chips stacked on the gaming table are decided even when the chips captured in the first image include one or more chips which are not recognized from the second image and/or the chips captured in the second image include one or more chips which are not recognized from the first image.

3 . The chip recognition system according to claim 1 , wherein the number and the position of the chips stacked on the gaming table are decided even when the chips captured in the first image include one or more chips which are not appeared in the second image and/or the chips captured in the second image include one or more chips which are not appeared in the first image.

4 . The chip recognition system according to claim 1 , wherein the number and the position of the chips stacked on the game table are decided using the number and the position determined from one of the first image and the second image having more pixels than the other.

5 . The chip recognition system according to claim 1 , wherein the number and the position of the chips stacked on the game table are decided using the number and the position determined from one of the first image and the second image being more in focus than the other.

6 . The chip recognition system according to claim 1 , wherein the number and the position of the chips stacked on the game table are decided using the number and the position determined from one of the first image and the second image being captured by more closely to the chips stacked on the game table.

7 . The chip recognition system according to claim 1 , wherein:
the first game recording apparatus includes a first camera, the second game recording apparatus includes a second camera, and the first camera and the second camera are installed in different locations and/or at different angles such that the first camera and the second camera capture different aspects of same chips of the chips stacked on the gaming table, thereby there are one or more chips that are determined by the image analysis of the first image but are not determined by the image analysis of the second image.

8 . The chip recognition system according to claim 7 , wherein the number and the position are decided based on at least one of:
respective positions of the first camera and the second camera, and respective numbers of pixels of the first camera and the second camera.

9 . The chip recognition system according to claim 2 , wherein the number and the position are decided based on at least one of:
respective focal positions of the first image and the second image, definitions of the first image and the second image, and past results of number and position of chips stacked on the gaming table decided by the at least one processor respectively based on the first game recording apparatus and the second game recording apparatus.

10 . The chip recognition system according to claim 1 , wherein the at least one processor is configured to:
determine, based on results of the respective image analyses, a respective type of at least one chip in the first image and the second image; and decide a type of each of at least one of the chips stacked on the gaming table based on the respective types determined from the first image and the second image.

11 . The chip recognition system according to claim 10 , wherein:
the first game recording apparatus includes a first camera, the second game recording apparatus includes a second camera, the first camera and the second camera are installed in different locations and/or at different angles such that the first camera and the second camera capture different aspects of same chips of the chips stacked on the gaming table thereby there are one or more chips that are detected by the image analysis of the first image but are not detected by the image analysis of the second image.

12 . The chip recognition system according to claim 11 , wherein the at least one type is decided based on at least one of:
respective positions of the first camera and the second camera, and respective numbers of pixels of the first camera and the second camera.

13 . The chip recognition system according to claim 10 , wherein the at least one type is decided based on at least one of:
respective focal positions of the first image and the second image, definitions of the first image and the second image, and past results of one or more types of chips stacked on the gaming table obtained by the at least one processor respectively based on the first game recording apparatus and the second game recording apparatus.

14 . The chip recognition system according to claim 1 , wherein the first game recording apparatus and /or the second game recording apparatus is configured to capture a part of the gaming table.

15 . The chip recognition system according to claim 1 , wherein the first game recording apparatus and /or the second game recording apparatus is configured to capture all of the gaming table.

16 . A chip recognition system for a gaming table on which chips are stacked, the chip recognition system comprising:
a first camera configured to capture a first image of the gaming table; a second camera configured to capture a second image of the gaming table; and at least one processor configured to:
perform an image analysis of the first image using an artificial intelligence technology and an image analysis of the second image using an artificial intelligence technology;
determine, based on results of the respective image analyses, respective numbers and positions of the chips appeared in the first image and the second image; and
decide a number and a position of the chips stacked on the gaming table based on the respective numbers of the chips determined by the image analyses of the first image and the second image,
wherein the first camera and the second camera are installed in different locations and/or at different angles such that the first camera and the second camera capture different aspects of same chips of the chips stacked on the gaming table, thereby there are one or more chips that are determined by the image analysis of the first image but are not determined by the image analysis of the second image.
