LICENSE PLATE RECOGNITION SOLUTION

LPD/ANPD: Detects the vehicle license plate in the camera view, captures the license plate image.
LPR/ANPR: Recognizes the license plate by identifying license number from detected plate.

Applications:

  • Parking Management: Detection of vehicles with ingress into the parking area but no egress after timeout.
  • Traffic Monitoring: Red light violation detection or any other traffic rule violation detection.
  • Law Enforcement: Stolen cars detection, Place of registration tracking through traffic surveillance.
  • Task Automation: Systems can trigger operations such as access control / boom barriers etc.
  • Automatic Toll Management: Recognized vehicles can be charged the toll fees automatically.

How It Works

  • License Plate Detection & Capture: Clear image, captured in the camera, is processed for presence of vehicle license plate and on successful detection of license plate the license plate is captured.
  • Segmentation & Extraction: The captured license plate image is segmented into optically recognized characters and the alpha numeric value is extracted.
  • License Number Storage & Matching: The license plate identity (the alpha-numeric code) is stored in the database. There is option for the matching the extracted code with the existing entries in a list of registered license plates.
  • LPR Alarm: Depending upon match or mismatch the license plate is recognized or unrecognized with respect to registered database. The user has options to manually examine the code and modify if required.

Camera Installation

  • Height of installation = approx. 4 feet
  • Camera focus to be adjusted for each character of License Plate to have min. width = 16 pixels, min. height = 24 pixels and good separation between the characters.
  • Good quality camera with high shutter speed. Full HD, 120 DB WDR, 30 fps Frame Rate.
  • Illumination min 200Lux, with night IR illuminator
  • Optional: For driver image along with captured license plate image, another angular camera should be installed at a height of 5-6 feet, focussing to the area where driver face would typically appear. Illumination should be Min. 200 lux for the face detection.
  • Typical camera installation as below (Cam 1 – LPR Cam, Cam 2 – Face Capture Cam):
