ANPR (Automatic Number Plate Recognition Systems) in mobile systems

ANPR in mobile systems

Recent advances in technology have taken ANPR (Automatic Number Plate Recognition Systems) from fixed applications to mobile ones. Scaled-down components at more cost-effective price points have led to a record number of deployments by law enforcement agencies around the world. Smaller cameras with the ability to read license plates at high speeds, along with smaller, more durable processors that fit in the trunks of police vehicles, allow law enforcement officers to patrol daily with the benefit of license plate reading in real time, when they can interdict immediately.Despite their effectiveness, there are noteworthy challenges related with mobile ANPRs (Automatic Number Plate Recognition  Systems)  One of the biggest is that the processor and the cameras must work fast enough to accommodate relative speeds of more than 100 mph (160 km/h), a likely scenario in the case of oncoming traffic. This equipment must also be very efficient since the power source is the vehicle battery, and equipment must be small to minimize the space it requires. Relative speed is only one issue that affects the camera's ability to actually read a license plate. Algorithms must be able to compensate for all the variables that can affect the ANPRs (Automatic Number Plate Recognition  Systems) ability to produce an accurate read, such as time of day, weather and angles between the cameras and the license plates. A system's illumination wavelengths can also have a direct impact on the resolution and accuracy of a read in these conditions.

Relative speed is only one issue that affects the camera's ability to actually read a license plate. Algorithms must be able to compensate for all the variables that can affect the ANPRs (Automatic Number Plate Recognition  Systems) ability to produce an accurate read, such as time of day, weather and angles between the cameras and the license plates. A system's illumination wavelengths can also have a direct impact on the resolution and accuracy of a read in these conditions.Installing ANPR cameras on law enforcement vehicles requires careful consideration of the juxtaposition of the cameras to the license plates they are to read. Using the right number of cameras and positioning them accurately for optimal results can prove challenging, given the various missions and environments at hand. Highway patrol requires forward-looking cameras that span multiple lanes and are able to read license plates at very high speeds. City patrol needs shorter range, lower focal length cameras for capturing plates on parked cars. Parking lots with perpendicularly parked cars often require a specialized camera with a very short focal length. Most technically advanced systems are flexible and can be configured with a number of cameras ranging from one to four which can easily be repositioned as needed. States with rear-only license plates have an additional challenge since a forward-looking camera is ineffective with incoming traffic. In this case one camera may be turned backwa

Imaging Hardware

At the front end of any  ANPR (Automatic Number Plate Recognition Systems) system is the imaging hardware which captures the image of the license plates. The initial image capture forms a critically important part of the  ANPR (Automatic Number Plate Recognition Systems) system which, in accordance to the Garbage In, Garbage Out principle of computing, will often determine the overall performance.License plate capture is typically performed by specialized cameras designed specifically for the task. Factors which pose difficulty for license plate imaging cameras include speed of the vehicles being recorded, varying ambient lighting conditions, headlight glare and harsh environmental conditions. Most dedicated license plate capture cameras will incorporate infrared illumination in order to solve the problems of lighting and plate reflectivity. Many countriesow use license plates that are retroreflective. This returns the light back to the source and thus improves the contrast of the image. In some countries, the characters on the plate are not reflective, giving a high level of contrast with the reflective background in any lighting conditions. A camera that makes use of active infrared imaging (with a normal colour filter over the lens and an infrared illuminator next to it) benefits greatly from this as the infrared waves are reflected back from the plate. This is only possible on dedicated  ANPR (Automatic Number Plate Recognition  Systems) cameras, however, and so cameras used for other purposes must rely more heavily on the software capabilities. Further, when a full-colour image is required as well as use of the  ANPR (Automatic Number Plate Recognition  Systems) retrieved details it is necessary to have one infrared-enabled camera and one normal (colour) camera working together.To avoid blurring it is ideal to have the shutter speed of a dedicated camera set to 1/1000 of a second. Because the car is moving, slower shutter speeds could result in an image which is too blurred to read using the OCR software, especially if the camera is much higher up than the vehicle. In slow-moving traffic, or when the camera is at a lower level and the vehicle is at an angle approaching the camera, the shutter speed does not need to be so fast. Shutter speeds of 1/500 of a second can cope with traffic moving up to 40 mph (64 km/h) and 1/250 of a second up to 5 mph (8 km/h). License plate capture cameras can now produce usable images from vehicles traveling at 120 mph (190 km/h). To maximize the chances of effective license plate capture, installers should carefully consider the positioning of the camera relative to the target capture area. Exceeding threshold angles of incidence between camera lens and license plate will greatly reduce the probability of obtaining usable images due to distortion. Manufacturers have developed tools to help eliminate errors from the physical installation of license plate capture cameras

Circumvention techniques

Vehicle owners have used a variety of techniques in an attempt to evade  ANPR (Automatic Number Plate Recognition  Systems) systems and road-rule enforcement cameras in general. One method increases the reflective properties of the lettering and makes it more likely that the system will be unable to locate the plate or produce a high enough level of contrast to be able to read it. This is typically done by using a plate cover or a spray, though claims regarding the effectiveness of the latter are disputed. In most jurisdictions, the covers are illegal and covered under existing laws, while in most countries there is no law to disallow the use of the sprays.Other users have attempted to smear their license plate with dirt or utilize covers to mask the plate. Novelty frames around Texas license plates were made illegal in Texas on 1 September 2003 by Texas Senate Bill 439 because they caused problems with ANPR (Automatic Number Plate Recognition  Systems) devices. That law made it a Class C misdemeanor (punishable by a fine of up to US $200), or Class B (punishable by a fine of up to US $2,000 and 180 days in jail) if it can be proven that the owner did it to deliberately obscure their plates.^[15] The law was later clarified in 2007 to allow Novelty frames.If an ANPR (Automatic Number Plate Recognition  Systems) system cannot read the plate it can flag the image for attention, with the human operators looking to see if they are able to identify the alphanumerics. In order to avoid surveillance or penalty charges, there has been an upsurge in car cloning. This is usually achieved by copying registration plates from another car of a similar model and age. This can be difficult to detect, especially as cloners may change the registration plates and travel behavior to hinder investigations. Other possible options include IR emitting LEDs around the license plate which would serve to "blind" cameras.

Russian ANPR Systems

Russian ANPR System (Automatic Number Plate Recognition) is where your car can have its number plate read via a video camera and this information is then matched against various computer databases, for example: the DVLA (Driver Vehicle Licence Authority), PNC (Police National Computer), motor insurers databases and local police force intelligence systems. In addition, many bailiff companies now use ANPR to locate vehicles with an unpaid PCN. The titanHz is special Russian NPR System(Number Plate Recognition) software, which until now has many times proved the efficiency and reliability. The Russian police has been using this number plate recognition system since 1994. The titanHz Russian ANPR System (Automatic Number Plate Recognition) can be installed in a patrol car and is able to catch the licence plate number of vehicles even at high speed. Russian ANPR System (Automatic Number Plate Recognition) technology is used for enforcement with cameras that capture pictures of license plates of vehicles that fail to relay a usable tag ID. Information regarding the owners of such vehicles is obtained from the State’s vehicle registry.

In Russian ANPR System (Automatic Number Plate Recognition) technology ANPR System(Automatic Number Plate Recognition) uses OCR (Optical Character Recognition) on to read images taken of Vehicle License Plates. The cameras used can include existing road-rule enforcement or closed-circuit television cameras as well as mobile units which are usually attached to vehicles. Some systems use infrared cameras to take a clearer image of the plates. Some license plate arrangements use variations in font sizes and positioning – Russian ANPR Systems (Automatic Number Plate Recognition) must be able to cope with such differences in order to be truly effective. More complicated systems can cope with international variants, though many programs are individually tailored to each country. Overall, there is an error rate that makes human oversight necessary. (Wikipedia, citation below) As of 2006, systems can scan number plates at around one per second on cars traveling up to 100 mph (160 km/h). They can use existing closed-circuit television or road-rule enforcement cameras, or ones specifically designed for the task. They are used by various police forces and as a method of electronic toll collection on pay-per-use roads, and monitoring traffic activity such as red light adherence in an intersection.

Japanese ANPR Systems

Japanese ANPR Systems (Automatic Number Plate Recognition) is a mass surveillance method that uses OCR (Optical Character Recognition) on images to read Vehicle Registration Plates. They can use existing closed-circuit television or road-rule enforcement cameras, or ones specifically designed for the task. They are used by various police forces and as a method of electronic toll collection on pay-per-use roads and cataloging the movements of traffic or individuals. Japanese ANPR System (Automatic Number Plate Recognition ) can be used to store the images captured by the cameras as well as the text from the license plate, with some configurable to store a photograph of the driver. Systems commonly use infrared lighting to allow the camera to take the picture at any time of the day. Japanese ANPR System (Automatic Number Plate Recognition) technology tends to be region-specific, owing to plate variation from place to place. Concerns about these systems have centered on privacy fears of government tracking citizens' movements, mis-identification, high error rates, and increased government spending.

Identifying stolen and wanted cars without resorting to a manual check of police records is now possible. The Japanese ANPR System (Automatic Number Plate Recognition) is the new weapon of gendarmes in the fight against crime and trafficking. This will also be weapon against crime in general when you consider that a criminal uses a vehicle to access the place of his crime or to escape. 500 vehicles equipped with this new technology will be deployed nationwide in France in the next few months.

Two technologies are completely integrated in the light bar of patrol vehicles; video protection systems and automatic numberplate recognition systems ('LAPI' in French). The complete system is made up of six colour video cameras (videosurveillance 360° around the vehicle with zoom cameras in the front and rear) and two infrared Japanese ANPR System(Automatic Number Plate Recognition) cameras, coupled with a OCR (Optical Character Recognition) software.

The Japanese have been abroad to learn best practices from the countries which are leaders in these new technologies : i.e. the UK ('Targeting the criminals through their use of the roads'), Italy ('Falco' system of the Carabinieri), the Netherlands and the USA (LPR and operation IMPACT). The titanHz are piloting other 'LAPI' devices; on board helicopters, mobile on a tripod (similar to the current automatic radar controls), and fixed in strategically important areas (motorways, ringroads etc). The titanHz promote the idea of multi-partnership between the ministry of Interior and the Transports to develop ANPR (Automatic Number Plate Recognition Systems) fixed sites on the main trunk road network. Next step will be the creation of a national dedicated date centre or back-office facility (to be called "STCL"). The idea is to have the 500 patrol cars not deployed "stand-alone" and to do criminal investigation and intelligence with Japanese ANPR System (Automatic Number Plate Recognition Systems) data at national level

Functionality

The system reads the plates of vehicles encountered by the titanHz patrol car, by day and at night, whatever the weather conditions. The manufacturers predict a theoretical reading of 5,000 number plates an hour. The 'LAPI' system compares the read number plates with the database of stolen and wanted vehicles in real time from the computer installed in the patrol car. In the case of a hit, the system sets off an alarm; the gendarmes intercept the potentially stolen car and arrest its driver. This association between Japanese ANPR (Automatic Number Plate Recognition) and video protection opens the way to other new and efficient road policing. It helps as well with community policing, road safety, crime investigation and anti-terrorism. The "L2V" gendarmerie car (L stands for LAPI, V for videosurveillance, V for video assisting law enforcement and speed detection) is a real weapon designed for nationwide policing, control of strategic routes, community policing and road policing at the same time.The "L2V" concept is complete and versatile as it includes a mobile in-car speed detection and video recording system complete with an automatic number plate recognition system.

1. LAPI detects all stolen and wanted cars, whether stopped or travelling at high speed whether this be during a routine patrol or during an investigation or anti-terrorism case

2. The video protection 360° around the patrol vehicle protects the gendarmes against complaints and makes the offence impossible to contest 

3. The video recording system assists law enforcement, i.e. facilitates the identification of criminal acts and traffic offences most likely to cause fatal accidents (telephoning at the wheel, non-use of seat-belts, etc.) and allows the identifications of the perpetrators of these crimes. A speed detection system helps tackle speed offences by measuring the average speed. 'LAPI' alarms are sent in real time to the "CORG" (the gendarmerie operations centre at regional level)in the form of localisation on a map and to the patrol vehicles in the area thanks of the onboard computer. The videos recorded by the vehicle can also be sent to the "CORG" by the onboard computer, to show the regional command vital information about the situation on the ground (for example, acts of delinquencies in a suburb, a major road traffic accident on a motorway or traffic conditions by blizzard).

MULTIEYE Japanese ANPR

The automation of incoming/outgoing saves money and controls access authorizations at the same time. The parking time of vehicles can be determined and analyzed which helps optimizing your logistics. By using the Japanese ANPR Systems (Automatic Number Plate Recognition) in parking garages / parking lots unauthorized long-term parking would be prevented. Upon the return of rental cars at unmanned stations the actual return times are recorded and potential damages on the vehicles documented by additional high-resolution cameras.
The Japanese MULTIEYE ANPR Systems (Automatic Number Plate Recognition Systems) may be used as low-priced add-on software module for the MULTIEYE video recorders or for MULTIEYE-NET. The number plates are stored image conform and compared to the database entries. No separate hardware is necessary for the Japanese ANPR Systems (Automatic Number Plate Recognition). The standard version offers the surveillance of 2 lanes; the system can be expanded to monitor up to 8 lanes (depending on recorder performance) and thus represents a low-risk and future-proof investment. The MULTIEYE-ANPR is available in two designs: Traffic and Gate, both support analog as well as IP-cameras. Currently number plates from 125 different countries can be recognized.

Chinese ANPR Systems

The uses of Chinese ANPR (Automatic Number Plate Recognition) are many and it is already proving a popular system with police and private contractors to catch and even prosecute. It also has a number of practical uses including the ability to ease congestion and monitor journey times.

titanHz Chinese ANPR or also known as Chinese ALPR is an innovative Chinese ANPR (Automatic Number Plate Recognition) for traffic surveillance, toll collection, traffic management, enforcement parking and many other projects where accuracy, speed and automation are essential objectives. Due to its outstanding technology, its high accuracy rate, the speed of image processing and its adaptability, titanHz Chinese ANPR technology (Automatic Number Plate Recognition System) is among the best of its class. With its advanced character recognition not only does it capability of reading Latin characters, the Chinese ANPR engine (Automatic Number Plate Recognition) can read Chinese, Cyrillic (and with special training any other types of) number plates as well. The Chinese ANPR software (Automatic Number Plate Recognition) can execute continuous license plate reading even at vehicle speeds of up to 150mph. This feature is especially important in convicting speed limit violators or for use in automatic toll collection projects, just to mention a few. 

                             

How Chinese ANPR Works

Chinese ANPR (Automatic Number Plate Recognition) uses OCR (Optical Character Recognition) to identify the numbers and letters on a number plate. These are then usually stored in a central database and as long as the cameras themselves are set up for Chinese ANPR Systems (Automatic Number Plate Recognition) they can be used to cover a surprisingly large amount of space. Two cameras can cover both directions of the 27 lane Dart-ford crossing motorway.

Monitoring Traffic

titanHz Chinese Camera's are being installed in more and more police traffic cars as well as specialist police vans and CCTV vans. The cameras fitted in these vehicles usually operate forwards and to the side of the vehicles and they can be portable, fixed, or even covert giving a great range of opportunities to the police force.

Parking Management

Private uses of the Chinese ANPR System (Automatic Number Plate Recognition) include parking management. Pay and display car parks can be difficult and costly to police and monitor regularly and routinely. However, by installing Chinese ANPR Cameras (Automatic Number Plate Recognition) at the entrance and exit it is possible to accurately locate every car that enters and exits, therefore determining how long they have spent within the car park.

Congestion Charging

Congestion charging is another viable use of the Chinese ANPR System (Automatic Number Plate Recognition) . Rather than having to employ numerous toll booths and operators, and then demand that every vehicle stop, using an Chinese ANRP System (Automatic Number Plate Recognition) would allow for each car to be checked in order to determine whether or not the driver has a valid parking license or permit. This means that thousands of vehicles can pass through the congestion charge area each hour.

Petrol Forecourts

Petrol station forecourts also operate Chinese ANPR Cameras (Automatic Number Plate Recognition). These are used to record details of non-paying customers, whether they are unable to pay or drive off without making payment. Cashiers can be warned as soon as a car drives up that is found to be on the Petrol Forecourt Database of Offenders. This not only includes petrol thieves but also customers that are flagged as previously unable to pay.

The Chinese ANPR system comprises of the following components:

1. Chinese ANPR Camera: A camera is required to capture an image of the vehicle license plate under changing environmental conditions both, day and night, with no operator supervision. A typical Chinese ANPR Camera (Automatic Number Plate Recognition) will have a fast shutter to reduce motion blur of vehicles travelling at high speeds. Traditional ANPR systems use CCTV style cameras. These cameras tend to use low resolution, interlaced sensors with an analog signal output. These type of cameras are not suitable for applications where the vehicle is travelling at high speed as the interlaced format will cause the image of the vehicle to be distorted. Many manufactures of Chinese ANPR Systems (Automatic Number Plate Recognition) tend to work around the shortcoming of interlaced cameras by working with either the odd or even field of the interlaced image. This has the unwanted side effect of reducing the effective vertical resolution in half which can affect the reading accuracy of the system.In comparison, many of the newer dedicated Chinese ANPR Camera Systems (Automatic Number Plate Recognition) use high resolution, progressive scan sensors with digital interface connectivity options. With a higher resolution sensor, it is possible to monitor more than a single lane at a time. Also progressive scan sensors are more suitable for applications where vehicles are travelling at speed.

 2. Light Source. A Chinese ANPR System (Automatic Number Plate Recognition) must operate 24 hours a day throughout the year. Strong sunlight and vehicle headlights at night, can saturate the camera sensor, creating bright spots on the image, making it difficult to view and read the license plate. To resolve this problem, modern Chinese ANPR Systems (Automatic Number Plate Recognition) use IR (infra red) lighting with optical filters to illuminate the plate and minimise the affects of ambient lighting. Many countries use retroreflective plates. IR illumination is reflected from the vehicle plate to improve contrast of the plate within the image.  

Video Capture. Where analog cameras are used, the image must be digitised so that it can be processed by the PC. The purpose of the video capture card is to take the analog video output from the camera and convert it into a standard digital format for further processing. Video acquisition cards often have one or more video channels allowing capture from several cameras at once. Digital camera systems with IP connectivity do not require a separate video capture card as the image is digitised at the camera.  

4. Computer. The purpose of the computer is to analyse the captured image and to read the license plate, if one is present in the image. This is the most complex part of the system and is the main component that distinguishes one manufacturer from another. Note: More recently, PC computer based license plate recognition systems are being superseded by intelligent, all-in-one type systems where the processor, camera and lighting are all combined into one compact unit. These systems typically use DSP and/or FPGA hardware with customized deterministic operating systems

ANPR Congestion Charging Solutions

               Traffic congestion schemes, of increasing significance in urban centres where there are concerns about pollution or the capacity of streets to accommodate a large number of vehicles during peak hours, seek to exclude classes of motor vehicles (for example cars owned by non-residents) or to allow entry of vehicles on a selective basis (eg at a particular time or subject to a financial penalty). In essence most schemes involve charging for use of public streets and have thus proved to be controversial, although sometimes supported by residents of the particular precinct.

ANPR Systems (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 ANPR Systems (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, and even the reduced penalty charge (if paid within 14 days) is more than six times the daily charge.

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.
