Card recognition system, card handling device, and method for tuning a card handling device
First Claim
1. A card recognition system, comprising:
- 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 configured to;
perform an image processing analysis of the raw image to identify measurements related to 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 during a calibration mode based, at least in part, on the image processing analysis, the calibration file including the measurements from the image processing analysis for processing cards during a subsequent card recognition mode.

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.

21. A card handling device, comprising:
-
a card infeed; a card output; and a card recognition system, including; an image sensor configured to capture an image of a card passing from the card infeed to the card output; and a card recognition processor configured to automatically generate a calibration file using an image analysis process of the image during a calibration mode prior to card recognition mode, the calibration file including measurements from the image analysis process of the image for at least one of a size of a rank and a suit symbol of the card within the image. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
