A system that spots a car plate in an image and reads its number.
It is like a parking lot camera with a tiny detective hat. A car zooms past. It writes down the plate and time.
You see it at parking gates and on roads. Dirt or bright glare can make it read the wrong plate.
Computer Vision
ALPR is a common use of Computer Vision on roads.
Object Detection
Object Detection finds the plate before ALPR reads it.
OCR
OCR turns the plate characters into searchable text.
