The fictional police spy helicopter from the movie Blue Thunder is taking a big step toward becoming a reality. Police in the UK have successfully tested a 160 MPH helicopter that can read license plates from as much as 2,000 feet in the air. The Eurocopter EC135 is equipped with a camera capable of scanning 5 cars every second. Essex Police Inspector Paul Moor told the Daily Star newspaper: "This is all about denying criminals the use of the road. Using a number plate recognition camera from the air means crooks will have nowhere to hide."
The use of Automated Plate Number Recognition (ANPR) is growing. ANPR devices photograph vehicles and then use optical character recognition to extract license plate numbers and match them with any selected databases. The devices use infrared sensors to avoid the need for a flash and to operate in all weather conditions.
