1. A system for recognizing chips placed on a game table on which a game using chips is played, the system comprising:
a single camera configured to capture a chip stack comprising a plurality of chips stacked vertically and displaced from each other and placed on the game table to acquire a captured image; and
a control device configured to determine a position, a type, and a number of chips placed on the game table by analyzing one captured image acquired by the single camera,
wherein:
the single camera is configured to acquire the one captured image including a plurality of chip stacks having different distances and directions of observation from each other when there are the plurality of chip stacks by capturing the chips on the game table from diagonally above,
the single camera is configured to acquire the one captured image, which shows a top surface of the topmost chip in the chip stack and sides of the plurality of chips comprising the chip stack, by capturing the chips on the game table from diagonally above,
the control device is configured to determine a location of each of the plurality of chip stacks, the type of each of the plurality of chips in each of the plurality of chip stacks, and the number of chips in each of the plurality of chip stacks by using artificial intelligence techniques utilizing deep learning as image analysis, and
the control device is configured to determine the position, the type, and the number of chips by image analysis of the one captured image of a chip stack comprising a plurality of chips stacked in a zigzag manner.
