How it works
ANPR is a technology that automatically reads vehicle registration marks (VRMs), allowing these details to be compared against database records.
ANPR cameras take an images of vehicle number plates; these images are passed to a reader, which locates the VRM and reads the letters and characters so that they can be identified using Optical
Character Recognition (OCR) software. An image of the number plate is then saved and checked against the database.
As a vehicle approaches the camera the software takes a series of 'snapshots' and stores them in a file. When the number plate is of sufficient size for the OCR software the frame is scanned and held in a list. This is carried out for a series of images according to the speed and position of the vehicle ensuring that the optimum view of the license plate is achieved.
ANPR capture is totally dependent on the correct set up of camera, lens, illumination, angle of view and configuration.
