Automatic Number Plate Recognition

Number Plate Recognition Systems

Automatic Number Plate Recognition (or as frequently called 'number plate recognition') is a special form of optical character recognition (OCR).

License plate recognition (LPR) is a type of technology, mainly software, that enables computer systems to read automatically the registration number (license number) of vehicles from digital pictures.

Reading automatically the registration number means transforming the pixels of the digital image into the ASCII text of the number plate.

While license plate recognition has special type of OCR technology, today optical character recognition (OCR) technology is considered strictly a type of technology - mainly software - that lets you scan paper documents and turn them into electronic, editable files.

From the LPR/ANPR point of view the image quality is always key factor. Capturing of fast moving vehicles needs special technique to avoid motion blur which can decrease the recognition accuracy dramatically. To ensure the right image quality short shutter time need to be used with the combination of high-power illumination.

The best illumination is the IR, because the retro-reflective plates reflect this kind of light very well and it is undetectable for the human eye. This combination works fine during day and night and provides constant good image quality.

Only dedicated ANPR cameras meet these requirements, like AHR’s ANPR cameras, which provide flexible shutter control with built-in IR flash and able to catch the vehicles up to 250km/h which is suitable for all kind of license plate reading applications.


What Can We Offer To You?

We design and develop high quality recognition software for the automatic recognition of vehicle license plates.
