OCR License Plate or Automatic License Plate Recognition (ALPR) is a system that identifies and extracts data from vehicle license plates in a provided image. In practice, the ALPR system takes an input image containing vehicles with their license plates which might be captured from CCTV or other devices. It then extracts the valuable information including the plate numbers and the issuing provinces of all license plates found in the given image and returns them in a structured format to the user. This process effectively translates visual information into a format that's easily understandable by machines, laying the groundwork for a variety of business applications.
