Gambling chip recognition system
DCFirst Claim
1. A computer implemented gambling chip recognition system for automatically determining the number of chips and the value of each chip within a stacked pile of one or more chips comprising:
- an imager for generating an image of at least one chip;
data storage electrically interconnected to said imager for storing at least a portion of said image,said data storage storing a plurality of predetermined chip representations, wherein said plurality of predetermined chip representations define a gambling chip value classification system with each predetermined chip representation having a gambling chip value assigned thereto; and
a processor electrically interconnected to said data storage for processing said image to determine the number of chips within the stacked pile and generate a chip representation for each chip, said processor determining the number of chips within the stacked pile by identifying chip edges for each chip within said image.

Abstract
A computer implemented gambling chip recognition system having the ability to capture an image of a stack of gambling chips and automatically processing the image to determine the number of chips within the stack and the value of each. The system processor determines the classification for each chip in a stack by way of processing performed in real time on the image of the stack of gambling chips. The system further includes the ability to communicate the information derived from the stack of gambling chips to a video monitor and the ability to communicate the information to a main database where information is being compiled and stored about an individual gambler.

5. A computer implemented method for determining the number of chips and the value assigned each chip within a stacked pile of one or more gambling chips comprising the steps of:
-
imaging the stacked pile of chips; storing said image; determining the number of chips within the stacked pile of chips by identifying chip edges for each chip within said image; and determining a chip representation for each chip within the stacked pile of chips by comparing each said chip representation with a plurality of predetermined chip representations wherein each predetermined chip representation defines a casino chip having a specific monetary value. - View Dependent Claims (14, 15)

6. A gambling chip recognition system for automatically determining the number of chips and the value of each chip within a stacked pile of one or more chips comprising:
-
an imager for capturing a digital representation of an image representing the stacked pile of one or more chips; data storage electrically connected to said processor and; a processor electrically connected to said imager, said processor determining the number of chips within the stacked pile of one or more chips by identifying the edges of each chip, said edges of each chip identified by computing pixel variance value for pixels comprising said image, comparing said pixel variance values to a threshold variance values and applying an edge detection filter to said pixels comprising said image. - View Dependent Claims (7, 8, 9, 16)
