INTRODUCTION

• Automatic Number Plate Recognition (or 'number
  plate recognition') is a special form of optical
  character recognition (OCR).
• It enables computer systems to read automatically
  the registration number (license number) of
  vehicles from digital pictures.
• Reading automatically the registration number
  means transforming the pixels of the digital
  image into the ASCII text of the number plate.
• OCR technology scans paper documents and turn
  them into electronic, editable files.
• Capturing of fast moving vehicles needs special
  technique to avoid motion blur . To ensure the
  right image quality short shutter time is used
  with high-power illumination.

3

• The best illumination is the IR, because the
  retro-reflective plates reflect this kind of
  light and it is undetectable for the human eye.
• This combination works fine during day and night
  and provides constant good image quality.
• Only dedicated ANPR cameras meet these
  requirements, which provide flexible shutter
  control with built-in IR flash and able to catch
  the vehicles up to 250km/h which is suitable for
  all kind of license plate reading applications.

HOW TO BULIT ANPR SYSTEMS ?

• ANPR has two technological issues
• The quality of license plate recognition software
   with its applied recognition algorithms, and
• The quality of image acquisition technology, the
  camera and the illumination.
• The very key factor is the number plate
  recognition software.
• A sophistication recognition software should
  have following features
• the highest recognition accuracy
• the fastest processing speed
• the most type of number plates it can handle,
• the widest range of picture quality it can
  handle,
• the most tolerant against distortions of input
  data .

5

• The key technological parts of an APNR system
• high accuracy Optical Character Recognition (OCR)
  is an essential requirement
• technology image acquisition technology -
  determines the average image quality the number
  plate recognition algorithm has to work on.

ANPR SOFTWARE

• Different CARMEN software versions are used for
  different ANPR application areas
• There are basically 3 versions
• CARMEN Free Flow general-purpose license plate
  recognition engine , used for processing images
  of fast moving vehicles

  management applications where automatic
  identification of vehicles is needed.
• CARMEN Parking cost-effective solution, which is
  ideal for parking, vehicle entry and access
  control systems. It is capable of the automatic
  detection, identification and recognition of the
  registration number of any vehicle.

CARMEN PARKING LANE SOFTWARE

• used for one or two lanes of access control
  systems.
• With integration CARMEN Parking Lane into parking
  management systems, it is possible to automate
  vehicle entry to and exit from a car park or a
  secure zone and to use the recognized
  registration number for inventory management.
• specially developed for parking management
  applications where automatic identification of
  vehicles is needed.
• provides accurate and quick identification of
  vehicles without human assistance.
