The Application of Infrared Illumination to ANPR

The Application of Infrared Illumination to ANPR

If a standard colour or monochrome camera was focused to read number plates it would have to contend with a huge variety of lighting conditions, daytime, night-time, sunlight, backlight, headlights, and so on. One configuration simply would not cope with all conditions, so there is a need to provide a constant level and direction of illumination irrespective of any other conditions. And so we come to the development of special cameras for continuous capture of number plate data.he camera must be sensitive to the infrared part of the spectrum, to at least 850 nanometres. Then it must be fitted with a filter to restrict the visible part of the spectrum. The lens would have a manual iris set fully open and the shutter speed set to 1/1000th second. Finally an infrared source must be fitted adjacent to the camera. Therefore, taking advantage of the retro-reflective characteristics of number plates, the illumination from the illuminator will be reflected directly back to the camera. Thus only infrared light will be seen without any visible light or other reflections or refractions. The picture will of course be black with no detail except for the number plate. The OCR software then takes care of converting the image to usable code. Note that this is the sort of image on the monitor both day and night

 

This then is the core of ANPR technology, but there are many other factors to be considered. The first of these are the selection of lens and the distance to view the vehicle. The size of a UK license plate on cars and commercial vehicles is approximately 510mm long x 110mm high. Motorcycles are different being approximately 255 x 200. However more significantly, the minimum height of the letters must be 79mm. The current UK font is Charles Wright, although there are some illegal formats seen. The size of the number plate and the actual characters will need to be of a certain size when seen by the camera for the OCR software to function. One line of thought is that the number plate should be 18% of the scene width; I prefer to consider the vertical height of the characters, which from previous research should be 3% minimum for a 400 line camera. This in fact equates very closely to the 18% screen width but is more logical when considering different shapes of number plates. (For instance when a car plate is 18% of the screen a motorcycle plate would only be 7 %.) Also note that motorcycles currently do not have to carry a front number plate, but this could change in the future.

Portuguese ANPR Systems

Our Compliance and Quality Management software has been extended to encompass titanHz ANPR (Automatic Number Plate Recognition) technology. This system, called Portuguese ANPR Systems (Automatic Number Plate Recognition), is highly flexible suite of web-based software and hardware that can automatically read number plates by converting pictures into number plate text strings. The number extracted from the picture can then be used in a range of different control situations, either by Compliance or other enterprise management systems. Portuguese ANPR Systems (Automatic Number Plate Recognition) is a fully integrated turnkey system involving software, hardware and communication networks that can be configured many different ways to suit your requirements. Portuguese ANPR Systems (Automatic Number Plate Recognition) uses ANPR (Automatic Number Plate Recognition) technology as the basis to enable number plates to be extracted from standard video streams or still pictures. Portuguese ANPR Systems (Automatic Number Plate Recognition) is a mass-surveillance method that uses Optical Character Recognition (OCR) on images to read the number-plates on any vehicle. It can use existing closed-circuit television, road-rule enforcement cameras, or cameras specifically designed for the task. Portuguese ANPR Systems (Automatic Number Plate Recognition) can be used to store the images captured, as well as the text from the number plate. It is also able to store a photograph of the driver. Our system commonly uses infrared lighting to allow the picture to be taken at any time of the day. ANPR (Automatic Number Plate Recognition) technology tends to be region specific, owing to variation of number plates from place to place. Initially image manipulation techniques are used to detect, normalise and enhance the image of the number plate. Then the Optical Character Recognition (OCR) is used to extract the alpha-numerics of the number plate.

The ANPR (Automatic Number Plate Recognition) engine is the true genius behind the Portuguese ANPR Systems (Automatic Number Plate Recognition) system, and uses the ANPR (Automatic Number Plate Recognition) engine by Adaptive Recognition Portuguese. The key task of the ANPR (Automatic Number Plate Recognition) engine is to provide accurate reading capability “tuned” specifically for a country’s number plates style. ANPR (Automatic Number Plate Recognition) engine has been tuned for Brazil plates, providing brilliant accuracy and speed of resolution. Portuguese ANPR Systems (Automatic Number Plate Recognition) complements this technology perfectly by providing the complete solution, designed to suit the environment. This ensures the ANPR (Automatic Number Plate Recognition) Technology will provide you with the maximum advantage

Functional use of Portuguese ANPR Systems

Portuguese ANPR Systems (Automatic Number Plate Recognition) is also finding favour within non-supervised car parks as a means to control access via a white list. This white list contains a list of vehicles with known access rights. Suitable for hotel, apartment and company car parks, this negates the use of disposable paper tickets and wireless FOBs. Companies with large fleets are introducing Portuguese ANPR Systems (Automatic Number Plate Recognition) as a cost effective method of tracking their vehicles throughout their depots. Large supermarkets and chains are also beginning to utilize the information obtained from their car-parks as a way of highlighting demographic patterns with a view to maximizing profits. For any traffic management system to be a success, the read rate must exceed 99%. Traditionally most operators shied away from Portuguese ANPR Systems (Automatic Number Plate Recognition) when they discovered that their true read rates were rarely above 60%. In real world applications, this was the limit, not due to poor software but the result of using conventional CCTV systems to obtain the images. CCTV technology is 50 years old and does not lend itself well to computer recognition systems.

The titanHz Norwegian ANPR System (Automatic Number Plate Recognition) is one of the greatest world's leading Norwegian ANPR Systems (Automatic Number Plate Recognition), employing state of the art neural network techniques for character recognition. This capability ensures system efficiency and integrity for use in high volume or standard traffic flow situations. Norwegian ANPR Systems (Automatic Number Plate Recognition) are used extensively in policing and law enforcement and are now being used to monitor areas such as car parks, congestion zones and toll booths. Norwegian ANPR Systems (Automatic Number Plate Recognition) must quickly and accurately identify vehicles through the use of OCR (Optical Character Recognition). LED illuminators are ideal for use in Norwegian ANPR System (Automatic Number Plate Recognition) due to their long lifetimes, availability in a range of wavelengths and suitability for strobing. Norwegian ANPR System (Automatic Number Plate Recognition) illuminators must also be robust, particularly if being used in a mobile system, and long lasting as maintenance can be costly. titanHz provide illuminators with MTBFs of up to 100,000 hours. supplies some of the leading Norwegian ANPR System (Automatic Number Plate Recognition) manufacturers with LED illuminators. titanHz SpecBright Spotlights are used as illuminators for Norwegian ANPR System (Automatic Number Plate Recognition) and titanHz also supplies custom solutions to meet specific customer requirements.

major feature of the National Norwegian ANPR System (Automatic Number Plate Recognition) Data Centre for car numbers is the ability to data mine. Advanced versatile automated data mining software trawls through the vast amounts of data collected, finding patterns and meaning in the data. Data mining can be used on the records of previous sightings to build up intelligence of a vehicle's movements on the road network or can be used to find cloned vehicles by searching the database for impossibly quick journeys.

Functional use of Norwegian ANPR Systems

Norwegian ANPR System (Automatic Number Plate Recognition) has been used in such schemes to identify what vehicles are traversing a location, on the basis that the technology is less "invasive" than electronic tagging systems that require users to gain a RFID tag for the particular driver or vehicle. The registration database is typically linked to a billing system, with Norwegian ANPR System (Automatic Number Plate Recognition) being used to identify 'authorized' vehicles (which have usually paid for the privilege of using the local road network) and non-authorized vehicles, which are automatically issued with a fine. The Canada congestion pricing scheme (centred on a standard charge for private cars and commercial vehicles entering the zone during particular periods, with a 90% discount for residents and exemption for buses, taxis and disabled individuals) envisages that the penalty will be around per instance. while the current level of accuracy would not support an account-based charging system (for which a vehicle would have to be detected in order to be charged), it is sufficient for the enforcement of the current pre-pay system; individuals must pay the charge without knowing whether they have been detected.

Given the speed of processing and sufficient cameras it is possible to develop highly granular, time-specific and dynamic charging, eg different charges at various times of the day, higher charges when pollution reaches particular levels.

Highway Applications of Norwegian ANPR Systems

In com­mon with the statu­tory duty of any pub­lic body, the High­ways Agency will pro­vide assis­tance to the Police in the inves­ti­ga­tion of spe­cific seri­ous crimes (typ­i­cally those which carry a life sen­tence). The hash­ing process cre­ates a non-unique tag that may con­se­quently apply to a num­ber of vehi­cles. The High­ways Agency can­not there­fore be defin­i­tive about a spe­cific vehi­cle, and can only say whether or not one or more vehi­cles with that non-unique tag was observed at the loca­tion and within the spec­i­fied time parameters. As the data is non per­sonal infor­ma­tion (due to the non-unique tag for­mat) there are no Data Pro­tec­tion restric­tions on how long we keep it. Cur­rently, the data is kept indef­i­nitely for mod­el­ling the net­work effec­tively and antic­i­pat­ing dri­vers’ behav­iour in response to inci­dents on the road network .
