License Plate Recognition System


Introduction

  • License Plate Recognition is an image processing technology that is used to identify vehicles by their license plates.

  • Works by extracting the characters from an image.

  • Used for many applications: tollbooths, parking decks, border control, law enforcement, etc.

License Plate Recognition System


Our Product

  • We will design a license plate recognition system that will be used for law enforcement

  • Based on a Linux platform

  • Works with stationary vehicles

  • Customized for the Georgia License Plate
