In a single camera-frame time of 40 ms a recognition system, devised at an English university, can scan the number plates of vehicles in its field of view as they are driven along a motorway.
The new hybrid digital/optical pattern recognition system combines optical computing with latest digital electronic technology, offering massive computational power for number plate recognition in a flow of high density traffic.
The monitoring and control of high-density traffic flows have become very important issues for reasons of economy, security, law-enforcement and the environment.
Professor Chris Chatwin, head of the Advanced Technology Hub (the research centre), based in the School of Engineering and Information Technology at the University of Sussex, southern England, believes that the system is a great advance in the application of high-speed pattern-recognition technology for demanding unconstrained problems that have, until now, eluded solution.
As well as the rapid recognition of vehicle number plates while monitoring and controlling high-density traffic flows, other applications include recognition of bank notes, post codes on mail and security data.
