摘要： A method to identify a key profile, characterised by: illuminating with two laminar beams emitted by two laser light sources (18) the two sides of the shank of a key (6) driven to move axially relative to said beams; reading with two video cameras (20), fixed relative to said sources (18) and having their optical axis inclined to the planes in which said light beams lie, the two light profiles formed by said laminar beams striking the two surfaces of the shank of said keys (6); digitizing the optical images read in this manner, to obtain two sequences of signals representative of the profiles of the two lateral surface portions of the key (6), as instantaneously illuminated by said laminar beams and read by said video cameras (20); reconstructing from said signals, by means of a processor unit (22), a signal representative of the entire key profile; and comparing the thus reconstructed signal withthe signal representative of profiles stored in said processor unit (22) to obtain data identifying the profile of said read key.
