Key blank identification system with bitting analysis

摘要

A key identification system is provided. The key identification system comprises a sensing device configured to extract bitting information from a master key, and a logic configured to analyze the image. The sensing device may be configured to capture information about the bittings of the master key, such as an image of the bittings. The logic analyzes information about the bittings of the master key and compares it with bitting characteristics of known key blanks to determine the likelihood of a match between the master key and a known key blank.

1. A key identification system comprising:
a sensing system configured to extract bitting information from a master key; and a logic configured to analyze said bitting information to determine at least one geometric characteristic of the shape of said bittings of said master key and further to compare said geometric characteristic of said bittings with bitting characteristics of known key blanks to determine the likelihood of a match between said master key and a known key blank wherein said at least one geometric characteristic of the shape includes at least one of a depth of a bitting, a width of a bitting, a bitting profile shape, and a spacing between the bittings, and at least one of a—location, slope, angle, or radius of a feature of said master key; wherein said data related to bitting characteristics of known key blanks includes a set of bitting centers associated with a given key blank.
