  1. AUTOMATIC NUMBER PLATE RECOGNITION SYSTEM BY SUHAIL KHAN ROLL NO:31

  2. 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.

  4. 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.

  6. ANPR SOFTWARE • Different CARMEN software versions are used for different ANPR application areas • There are basically 3 versions • CARMENFree Flow : general-purpose license plate recognition engine , used for processing images of fast moving vehicles • CARMENParking Lane: developed for parking management applications where automatic identification of vehicles is needed. • CARMENParking: 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.

  7. CARMEN FREE FLOW SOFTWARE • It is highly accurate, fail safe and stable, fast and intelligent. • it provides the highest technological performance • It can be integrated into practically any ANPR system • Features: • offers general-purpose license plate reading from digital pictures of any type of sources. • provide high quality car plate recognition for very different type of images and plates with default settings. • 98.5% recognition rate (correct reading/total number of input)

  8. Applications: • Intelligent Transportation Systems (ITS), • security systems • motorway toll collection (highway toll collection), • traffic analysis, • police law enforcement, • state border control, • enforcement of traffic regulations, • vehicle theft prevention, • automation and simplification of airport, • harbor and warehouse logistics, • security monitoring of roads and checkpoints • vehicle surveillance

  9. CARMEN PARKING SOFTWARE • specially designed for parking systems, security systems and access control systems. • It has a unique integration level of license plate recognition technology, the video acquisition technology and the processing of multiple images of video streams. • It comes with an industrial quality native driver for image acquisition and video streaming, providing a plug-and-play core number plate recognition module (software and capture card) for car park and vehicle access control systems.

  10. Features: • offers flexible, • low maintenance, • effective and intelligent technology for car park operation. • reduces costs as well as increasing efficiency and security. • the Carmen Parking ANPR package contains the following elements: • Automatic number plate recognition engine • FXVD4mc_s grabber card • Functions library (ANSI C/C++, MSVC/C++, MSVB and Delphi, ActiveX, OCX) • Demo and test applications • Tutorial and sample programs both in executable and source code. • High Resolution Camera equipped with a special and synchronized IR flash.(optional)

  11. A parking lot equipped with Carmen Parking can provide: • Flexible and automatic vehicle entry to and exit from a car park • Management information about car park usage • Improved security for both car park operators and car park users • Improved traffic flow during peak periods • Vehicle recognition through date and time stamping as well as exact location • Comprehensive database of traffic movement can be managed • Applications: • car park management, • car parking automation, • occupation management, • automation of access control, • security access control, • flotilla management (car pool management), • automation of vehicle entry to and exit from car parks, • inventory management, • state border control

  12. CARMEN PARKING LANE SOFTWARE • used for one or two lanes of access control systems. • With integration CARMENParking 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.

  13. ANPR HARWARES • ANPR consists of following hardware products : • Image capturing -FXCAM LPR/ANPR camera series : to provide good quality images • ARH Car PC for Mobile ANPR applications : is a mobile PC with unique features like GPS receiver and GPS antenna. • Video signal digitizing -FXVD4 frame grabber card : the primary function of this card is digitizing the video signal.
