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 based, at least in part, on the image processing analysis.

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.
