Transcript AUTOMATIC NUMBER PLATE RECOGNITION SYSTEM


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.

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.

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 .

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.

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
 CARMEN Parking Lane: developed for parking
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.

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)

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,


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.

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)

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

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.

