The Home Office Centre for Applied Science and Technology invites expressions of interest for a study into the effects of the spacing between characters on the readability of the vehicle registration mark (VRM) on UK number plates by human observers and automatic number plate recognition (ANPR) systems.
In particular evidence is sought regarding whether non-standard character spacing as commonly found on ‘cherished’ plates affects the ability of ANPR systems to accurately read the plate, and also whether it affects human ability to read and remember the registration plate correctly, for example if witnessed at the scene of an accident.
