ANPR / LPR Design Calculator
Design licence plate recognition installations. Calculates plate pixel width, capture zone, camera angles and the shutter speed needed for the traffic speed.
Targets assume a clean, unobstructed plate with adequate illumination. Confirm the minimum pixel width your recognition engine requires, since it varies between products.
