Automatic Number Plate Recognition

ANPR (Automatic Number Plate Recognition) / LPR (License Plate Recognition) is a versatile technology that is currently used in many different traffic applications. This includes for example access control systems, high-speed applications such as free flow tolling and enforcement and dragnet investigation. Industrial cameras are most typically used because of their real-time compatibility. When outfitted with the proper sensor, they offer the necessary sensitivity to capture high quality images during short exposure times.

Certain regional peculiarities are crucial here, such as the size of the number plates; in Europe a horizontal resolution of 800 x 1000 pixels per lane is recommended. This grows to 1600 x 2000 pixels per lane for the USA, Middle East and China. In addition, depending on the number plate properties a monochrome camera variant with IR light support is preferred in Europe, while a color variant with white light support is helpful in the Middle East and China.
