Automatic Number Plate Recognition is a technique that reads automobile registration numbers by using optical character detection. This allows for faster and more accurate readings. In the beginning, ANPR was used by police forces all over the globe for the aim of upholding peace and order. However, it quickly made its way into the security industry as increasing numbers of service providers saw the advantages of using this technology for a variety of applications, including electronic toll collecting, parking facilities, and smart parking.

ANPR is a method of vehicle identification based on the analysis of photographs taken of the vehicle's license plate number. The goal is to create a reliable automated authorized vehicle recognition system based on the license plate. In order to control access to a highly restricted area, the system is installed at the entry point.

Such areas include military zones and the vicinity of high-ranking government buildings such as the Parliament, the Supreme Court, and the like.

How Does Automatic Number Plate Recognition Work?

Automatic Number Plate Recognition cameras automatically scan approaching vehicle number plates and match them to database information.

This camera captures a vehicle's number plate, which is subsequently scanned by a reader that transforms legitimate plates into Wiegand ID numbers. The access control system analyses this data to authorize or refuse vehicle entry. Upon verifying entrance, the controller opens the barrier/gate.

The following parts make up an ANPR system:

  • Lights up the license plate and snaps a picture of it using a high-definition infrared digital camera. For even more efficiency, some Automatic Number Plate Recognition (ANPR) cameras can capture high-speed pictures at up to 240 kilometers per hour.
  • A data processing server based on a computer.
  • Use of a wireless or wired local area network (such as Wi-Fi or Ethernet) to send a vehicle's identification number to a server for the purposes of checking its legitimacy.
  • Keep track of the license plates of authorized personnel in a database.
  • There are physical restrictions on accessing the building, such as barriers and gates.
  • Connecting the above elements is the access controller.

Benefits of ANPR for Business

Easy Installation:- ANPR systems are quite simple to set up; no specialized equipment is required, as well as the solution is available to use in a matter of hours.

24-hour Security:- By inserting the necessary vehicle's license plate into the system, ANPR offers automatic 24-hour access to secure locations or car parks. When pre-approved cars arrive, the barrier will be raised, enabling complimentary vehicle access both into and out of any secure facility. At any moment, access may be deleted or canceled.

Increased Revenue:- This technique is an excellent way to maximize car park revenues. When a vehicle enters the parking lot, the ANPR camera records the registration number, which may subsequently be utilized to optimize the on-site parking experience, resulting in improved earnings. To eliminate human input mistakes, cutting-edge payment equipment may be completely connected with ANPR data to match vehicle information recorded in the database.

No Tags Needed:- Where automobile tags are not an option, Automatic license plate system prices are often cheaper since it still provides lengthy automated vehicle access without the need to buy tags for each vehicle.


With the knowledge you gained from this guide, you should be able to put up an OpenCV and Python-based ALR system from the ground up. Our ANPR methodology used standard image processing and computer vision operations such as morphological operations, image gradients, thresholding, bitwise operations, and contours to pinpoint the precise location of a license plate inside an image. When input photographs all have the same illumination, and license plates are of the same size and shape, this approach will perform well (such as dark characters on a light license plate background).
