Key blank identification system with groove scanning
First Claim
1. A key identification system comprising:
- an imaging system including a camera configured to capture an image of the tip of a master key, wherein said image includes a contour;
a logic configured to analyze said captured image to determine characteristics of said contour and compare said characteristics with characteristics of known key blanks to determine the likelihood of a match between said master key and a known key blank; and
one or more mirrors positioned to allow said camera to capture two or more views of the master key wherein said characteristics of said contour are determined based on image data from at least said two or more views of said master key wherein at least one said view is substantially a tip end view, and wherein said logic calculates the geometry of the contour based on data from at least said two or more views of said master key.

Abstract
A key identification system is provided. The key identification system comprises an imaging system to capture an image of a master key, and a logic to analyze the captured image. The imaging system may be capture an image of a groove in the master key from an angle between perpendicular and parallel to the blade of said master key. The logic analyzes the captured image to compare characteristics of the groove with groove characteristics of known key blanks to determine the likelihood of a match between the master key and a known key blank. The key identification system may further compensate for displacement or orientation of the master key with respect to the imaging system when analyzing characteristics of the groove.

24. A key identification system comprising:
-
an imaging system including a camera in a first position configured to directly capture at least one image of one side of a master key, wherein said image includes a contour; at least one mirror positioned to allow said camera to capture at least one image of a second side of a master key from a second position wherein the second position is from a different angle than the first position, wherein the image from the second angle is substantially a tip end view; and a logic configured to analyze said captured images to determine characteristics of said contour and compare said characteristics with characteristics of known key blanks to determine the likelihood of a match between said master key and a known key blank. - View Dependent Claims (25)

26. A key identification system comprising:
-
an imaging system including a camera configured to capture an image of a master key, the image includes a first view and a second view; a first mirror positioned at a first position to allow said camera to capture the first view of the master key wherein the first view is a substantial tip end view, at least one second mirror positioned at a second position to allow said camera to capture a second view of the master key, wherein the first view is from a different angle than the second view; and a logic configured to analyze said captured image to determine characteristics of said contour and compare said characteristics with characteristics of known key blanks to determine the likelihood of a match between said master key and a known key blank.
