Automatic Number Plate Recognition (ANPR) Systems - Bollard ANPR

DIS-ANPR-B2

Automatic Number Plate Recognition (ANPR) uses optical character recognition on images to read the vehicle license plates. Most of the current ANPR solution includes many components such as cameras, lighting, software, mounting hardware etc.. Therefore it is never easy to install a cost-effective ANPR solution.

DISCOVER's Bollard ANPR automatically recognize, capture and store vehicle license plate numbers. Such vehicle information may be transfer to local or remote data center for management or enforcement traffic violators. Bollard ANPR has optional alarm input and output, to sound a siren or electronic strobe light .With simple optional integration it is also able to operate a car park barrier.

DISCOVER's Bollard ANPR is a newly designed ANPR with proven technology and reliability, flexibility in installation or even to be used as a mobile ANPR unit! DISA is suitable for installation on toll gate platform to capture and record all vehicles passing through. Collecting information such as:

  • Vehicle Number Plates
  • Time & Date
  • Vehicle Type
  • Location
  • Toll booth collector information and etc…

Features

Cost Effective Solution The Bollard ANPR is a All-in-One Standalone ANPR System, this eliminates the huge labor costs of installation of punting pole for cameras, camera mounting, lighting mounting, PC hardware installation etc.. Simply install the Bollard ANPR next to the car lane, example on the toll collection booth platform or on the side of the road. Or simply use as a mobile unit on top of a truck or jeep. The Bollard ANPR is standalone built-in with all ANPR components such as cameras, lighting, PC, video capture cards etc.. This Bollard ANPR is link by network to a laptop or desktop for temporary or permanent monitoring.
Reliable Since it is self-contained there is minimum maintenance required after the Bollard ANPR is properly installed and configured. Using Japanese high resolution camera for captures and built on proven technology applied in large scale ANPR projects, our Bollard ANPR is very reliable and minimum maintenance is required. All sensitive components such as camera and lenses are housed in a vandal-resistant stainless steel bollard-look-alike cylindrical tube.
Open Architectural Platform Built on open architectural platform our hardware and software are easily upgradeable and as when system requires. No proprietary hardware or software is used in the Bollard ANPR. Further R&D can be easily done based on customer’s requirements.
Advanced Technology Using the latest in optical character recognition and capture technology, our Bollard ANPR development is based on years of experience with large-scale ANPR projects. Our Bollard ANPR uses the high resolution progressive scan camera with advanced Wide Dynamic Range (WDR) to enable working in most harsh weather condition and environment on 24/7 basis. High quality components used in our Bollard ANPR also guarantee a longer lifespan for your investment. Our software are developed inhouse so we can do any upgrade or modification without any difficulty. We can easily customize to your specific requirements for your ANPR.
Compatibility Easily compatible with most other third party software or system. For example Bollard ANPR can be integrated into toll collection software.
Expandability Both hardware and software of our Bollard ANPR is built on modular form, leverage on standard IP infrastructure, expandability is no longer a problem! Bollard ANPR is built with long-term investment in mind.
Maintenance Free Bollard ANPR is built with self-diagnose and will immediately notify user in case of any mal-function of the system. With normal routine maintenance and cleaning is enough to keep the Bollard ANPR going for long years.
Practical Solution Bollard ANPR is designed with our user in mind. Based on the feedback from our large governmental users of our large-scale ANPR system we improve and customize the Bollard ANPR in order to allow more flexibility in operation as well as the accuracy of information.

Functions

License Plate Recognition and Captures Bollard ANPR applied optical character recognition technology to read and capture each vehicle license plate and convert into text form in the database. Basically it reads all alphanumeric characters from numbers, 0-9 and from alphabet A-Z. Other languages on the license plate needs some customization before accurately read and captures. Software also has self-learning and training abilities for auto error correction until a correct reading is accepted..
Video Captures Options Bollard ANPR captures recognizes and stores 1 panorama and 1 closeup angle video of the captured vehicle in database for future comparison or database queries. Also text information such as Time, Date, Location, Travel Speed, and Travel Direction are superimposed on the panorama video capture.
Alarm Reporting Optional software allows auto alarm for vehicles against traffic laws and orders. For example for vehicle over the legal speed limit, license plate number together with video and car speed will be auto uploaded to the control center via network for issue traffic ticket to the offender.

Trigger Methods

Bollard ANPR needs to know when to capture the vehicle license plate. A trigger determines the exact point of focus for the Bollard ANPR to capture the vehicle license plate. There are several ways of triggering the captures; however we recommend trigger by induction loop or video motion. The following table shows the various trigger methods and it’s advantages and disadvantages. Table showing various trigger methods for Bollard ANPR:
 

Trigger Method Description Advantage Disadvantage
Induction Loop
Detector		 A length of electrical wire buried just under the asphalt, when the huge mass of the metal body of car passes by alters the electromagnetic field around the loop  Accurate trigger method, clearly differentiate a moving vehicle, a stationery vehicle or a human  Needs extra labor to bury the electrical wire under the asphalt
Active IR Beam Block beam by the vehicle body Effective trigger, easy to install Cannot differentiate between a vehicle or a human. Suitable only for single lane pass through
Ultra Sound
Detector		 Use ultra sound reflection from car body mass Simple and easy installation Easy interference Efficiency much less than loop detector and Active IR beam
Video Motion
Detection		 Software detection of vehicle Low cost More false alarm
