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.
Claims19
A key identification system comprising:
- an imaging system including a first camera configured to capture a first image of a master key and a second camera configured to capture a second image of said master key, said first image different than said second image;
- a logic configured to map data points from said first image to corresponding data points from said second image to determine characteristics of a contour of said master key;
- and
- wherein said logic compares said characteristics of said contour with characteristics of known key blanks to determine the likelihood of a match between said master key and a known key blank.
