Coin identification system and method using image processing

摘要

A coin identification system and method is disclosed for determining the identity of a source coin by way of image processing. The system comprises a source coin image capture means, an image processing means, and an output that relays information to the user or sorts the coin according to its match results. The processing means compares at least one image of the source coin to a plurality of reference coin images, whereby the image of the source coin is manipulated and overlaid onto the reference coin images to determine if a match is available with a given probability. An embodiment of the system employs a coin collection and sorting device. Another embodiment contemplates a handheld electronic device that captures and processes the source coin. Both embodiments may connect to a remote server housing the reference coin information or store the information locally.

主权项

1. A coin identifying system using image processing, comprising:
an identification chamber that is adapted to receive a source coin therein; said source coin supported within said identification chamber via a perch; an image capture means for capturing an image of at least one side of said source coin when said source coin is within said identification chamber; an image processing means for comparing said image of said source coin with images of a reference coin; said image processing means comprising a processing means, a main memory, and a storage means; a database comprising images of said reference coin and said image of said source coin; said images of said reference coin individually compared against said image of said source coin to calculate a matching probability using at least one matching algorithm to determine a coin match output; wherein said coin match output is successful if said reference coin and said source coin match; wherein said coin match output is unsuccessful if said reference coin and said source coin mismatch.
