About License Plate Recognize APIs

The world has a way in which things work. The law requires that every property owned by an individual has a unique code that identifies it to its owner. The registration of a license or number plate in the vehicle is important as it enables law enforcement agents to perform their duties seamlessly. It also helps in identifying a vehicle in the issuing database.

The License plate recognition API uses the JSON input and the Rest API to achieve its functions. It has several features that work collaboratively. These features include crop photos of registration plates, an optional language code, confidence score, vertices, and timestamps.

How License Plate APIs work

The process begins with image acquisition from the camera. Images are usually in different colors red, green, and blue. Due to the possible image distortion that may occur, the image undergoes pre-processing to correct the errors. Then number plate detection resizes the image and converts it to a greyscale image. This process involves the identification of specific features in the number plate. Next is the output of character, character segmentation, and character recognition. In character recognition, the image is translated into meaningful text.


Law Agencies - The law enforcement officers at national, regional, and local levels use the license plate API to ensure that order prevails. They utilize it to track criminals and terrorist groups on the move. The software has a huge database where law enforcers can obtain information that can be used as evidence during an investigation.

Car Park Control Systems - Some locations are restricted for access and are preserved for authorized vehicles. In this case, the license plate recognition API is used to point out the license plate registered to the vehicle that has their car spaces reserved.

Developers - Developers use these APIs as a base to build a website and mobile applications that can be used to perform advanced operations in license registration for vehicles.


  • Traffic Control - Toll booths and weighbridges experience heavy traffic flow. The license plate API can identify vehicles with a toll fee, congestion charge, and valid permits. This process will ease the flow of traffic on the roads.
  • Pricing Package - The software allows you to receive invoices on charge fee. Usually, invoices and tickets are issued after utilizing a parking spot with this kind of APIs, and one can view the charges in real-time and initiate payment.

There are several of these APIs that are available as freemiums including License Plate Search, VicRoads Registration Check, OpenALPR and License Plate Recognition. The APIs that are available for free include License Plate Recognition-Platebber and Been plated API.
