Key blank identification system with groove scanning

摘要

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.

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.
