Card recognition system, card handling device, and method for tuning a card handling device
First Claim
1. A method for operating a card handling device, the method comprising:
- capturing images from a set of cards with an imaging device of a card handling device as the cards pass through the card handling device during a calibration mode;
storing the images of the cards in a non-transitory memory of the card handling device;
automatically generating a calibration file during the calibration mode with a processor of the card handling device, and storing the calibration file in the non-transitory memory, wherein the calibration file includes parameters responsive to the processor analyzing each image of the images for card identification information related to at least one of a rank area or a suit area of the card in the respective image; and
retrieving the parameters from the calibration file during a card recognition mode of the card handling device to determine an identity of at least one card passing through the card handling device during operation thereof.

Abstract
A card recognition system comprises an imaging device configured to capture a raw image of at least a portion of a card, and a processor operably coupled with the imaging device. The processor is configured to perform an image processing analysis of the raw image to identify measurements of at least one of a rank area around a rank of the card, and a suit area around a suit of the card, and automatically generate a calibration file based, at least in part, on the image processing analysis. A card handling device comprises a card infeed, a card output, and a card recognition system. A method for tuning a card handling device comprises capturing a plurality of images from a deck of cards, storing the images in memory, analyzing the plurality of images for card identification information, and generating a calibration file including parameters associated with the card identification information.

10. A card handling device, comprising:
-
an imaging device configured to capture images from a set of cards as the cards pass through the card handling device during a calibration mode; a non-transitory memory operably coupled with the imaging device and configured to store the images of the cards captured by the imaging device; a processor operably coupled with the imaging device and the non-transitory memory, the processor configured to control operation of the card handling device during both a card calibration mode and a card recognition mode, including to; automatically generate a calibration file during a calibration mode of the processor by analyzing each image of the images for card identification information related to at least one of a rank area or a suit area of the card in the respective image; cause the calibration file to be stored in the non-transitory memory; and retrieve the parameters from the calibration file during a card recognition mode of the card handling device to determine an identity of at least one card passing through the card handling device during operation thereof. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
