Garda to Get New Face Recognition Software for Tracking ...
Garda to Get New Face Recognition Software for Tracking ...
A five-year modernisation programme for the Garda will see new facial recognition software to target and track criminals and terrorists.Patrol cars will be fitted with automatic number plate recognition, every aspect of an investigation will be electronically recorded and crime scene kits such as digital cameras will be given to officers to record information for use later.The strategy up to 2021 sets crime prevention as the number one priority and focuses on policing several other key policing areas including reforming culture, victim support, new technology and cyber crime.Garda Commissioner Noirin O'Sullivan said the force was committed to openness and accountability after 43 official reports over the last 10 years exposed damning practices and failures."The next five years will see An Garda Siochana become a 21st century police and security service the people of our country can be proud of and our people can be proud to serve in," she said.The 116-page strategy document sets a target of turning the culture of the force into one of openness, transparency and accountability and notes how repeated state inquiries criticised it for being insular and defensive and for ignoring dissenting voices and constructive criticism.Among the new initiatives are bringing electronic capabilities up to date by giving officers on patrol access to real-time information on mobile devices.New technologies will be used to pinpoint "face in the crowd and shape in the crowd biometrics" to identify criminal and terrorist suspects.More civilians will be hired, more high visibility policing will be targeted in communities and patrols and checkpoints will be stationed in areas affected by particular crimes.Issues over the management of investigations which were exposed following whistle-blower Sergeant Maurice McCabe's claims will also be addressed.The Garda plan is to systematically catalogue evidence seized, electronically manage case files and deploy the correct resources to an incident or crime scene.On cyber crime, specialist units will be set up to liaise with overseas forces and to support front-line policing and state security while regional Computer Crime Investigation Units will be created.The Garda said it plans to increase information and intelligence exchange with other forces and deepen attention on those who benefit from or fund crime and terrorism.The Policing Authority, which is set to grill the commissioner in public over the next fortnight about the handling of whistle-blower complaints, said the new focus on victims and crime prevention, increasing visibility of officers, better training and resources is a milestone.Despite the commitments from the commissioner, the Association of Garda Sergeants and Inspectors dismissed the modernisation targets and warned it would not happen unless they secured their pay demands.General Secretary John Jacob said: "While we welcome a programme of reform, there can simply be no positive reform in the Garda organisation until Gardai are paid appropriately for the job that they do."Press Association
What You Should Know About ANPR(Automatic Number Plate Recognition) System
What You Should Know About ANPR(Automatic Number Plate Recognition) System
What You Should Know About ANPR(Automatic Number Plate Recognition) SystemIn this world of technology and innovation, almost everything is possible. Today, we can go to Mars, the moon, or any other planet we want to.No no, we are not going to discuss planets in this article. In earlier times, it was very difficult to note down the number of vehicles. Not just for traffic police but for security purposes also, its quite necessary to have technology like the ANPR system. With the help of this, one could have all the information about every vehicle which crosses the path of the ANPR system. What Is ANPR System?It is a software that helps to recognize the number plate automatically by accomplishing intricate optical character recognition on images to read the license plates of any vehicle.This system works in a very unique way. First, it takes the image of the vehicle as input and then returns the decoded vehicle plate, timestamp, and confidence status of the decoding algorithm. You will be amazed to know that it can analyze the image in 50 to 100 ms to allow real-time management. What Is The Use Of the ANPR System In India?It is really very important to tell you the need for ANPR in India. You will be amazed to know that, in every four-minute, there is one death due to over speeding of vehicles. Also, more than 200,000 cars are stolen per year. ANPR is used for various factors and in numerous fields like law enforcement security, neighborhood law, and parking management. With the help of which, you can easily monitor the average velocity of the vehicle, in addition to that, you will also get to know vehicles that exceed the speed limit.Hence, it can be said that with the help of this system, its really easy to maintain law and order, which in last, helps to minimize the amount of road accidents. Other Importance Of ANPR SystemBelow, we have listed some of the applications or we can say the advantages of an ANPR system. Improved Security Monitoring And Surveillance Less Manned Surveillance Still And Video Footage Tollgate vehicle accessChallenges Faced By ANPR SystemIts true that technology is very advanced nowadays but it also faces some of the difficulties and the same goes for the ANPR system. One of the main difficulties that is faced by ANPR is the nonuniformity of license plate number models for different places(cities or countries). RELATED QUESTION Do you need an Engineering degree to be called an Engineer? You can call yourself anything you want.but if you ADVERTISE yourself as an engineer you need to have an engineering license. This is otherwise known as a Professional Engineer. Its a very hard set of tests (one general, the other area specific). most people with engineering degrees will never have need or use of such a license in their careers. In general, you will need such a license if you need to sign off on a project. That is, to put your signature on a piece of paper stating that the particular work product meets certain standards set forth by the government. Such standards are usually put into place when there is a life safety risk at play (a licensed engineer will need to sign off in the design of a new bridge for instance, or a piece of medical equipment).software engineering used to be a licensable area. However it was found that there was so little demand and need, and so few people actually bothered to take the test that they no longer offer it. I have a degree in computer engineering. I am extremely well versed in all areas of engineering that are necessary to take the PE licensure exam. I never bothered to take it (well, thats not true as my university required everyone to sit for it as part of their graduation requirements, but it was not necessary to pass so you had large number of people show up, but their names down and then just leave, of which I was one). I served a summer internship at Siemens medics laboratories during my college career. I saw first hand what the rigor was for medical equipment design and decided that I wanted to go into telecoms and that did not require a PE license.I have never needed one in my now 35 year career. But I have worked in various projects where there was someone required to sign-off. Usually one person out of a team of dozens or hundreds of engineers
Police Officer Sacked for Using Number Plate Camera to Film Women
Police Officer Sacked for Using Number Plate Camera to Film Women
A police officer has lost his job after using a force camera to zoom in on a womans cleavage.Married PC David Smith used the automatic number plate recognition camera to look at the woman as she sat in beer garden.He initially blamed a colleagueof using the camera to zoom in to get closer footage of the woman in October 2011.But it was actually Smith who had used the camera inappropriately before downloading the footage on his home computer.Smith, who had been an officer for 19 years,was accused of five allegations of misconduct and, despite denying the charges, a panel concluded they had been proven after a two-day hearing at a police station in Hull, East Yorkshire.He said: I have got a clean record for working with vulnerable victims and I would not abuse that position.He claimed his colleague had taken the pictures because he was a flash clown and enjoyed a bit of a laugh.The panel heard how PC Smith also recorded video footage of a young woman in Harrogate, North Yorkshire, police station, before downloading the software onto his personal computer in 2012.PC Smith denied taking the footage for personal use, stating he was trying to get reception on his phone and did not know the camera was recording.When asked if he found the woman in the video footage attractive, PC Smith replied: Shes not ugly.PC Smith claimed he had accidentally transferred the images to his computer when he was doing a bulk download of pictures from his Blackberry mobile phone to his home console.He said he wanted to free up the memory on his phone for pictures of his family and for air show simulator games.He said: If you look at my service for the last 19 years and the positions I have held, you do not get these positions without having a good name. This was an isolated thing.Over his long-serving career, PC Smith was twice commended after rescuing a woman who was held at gunpoint in a taxi.However, during the hearing, he was accused of falling so far below the professional standards that he was dismissed without notice.In a separate incident in November 2012, PC Smith used a Cleartone automatic number plate recognition camera to replace car number plates with racist and offensive words, some describing male and female genitalia.PC Smith said he had taken pictures of the vehicles for future intelligence.The hearing also heard how the officer downloaded movie clips from an onboard police vehicle camera and a photograph of a bus parked in the street with no insurance, both without a policing purpose.He admitted taking the footage, but said it was for work purposes.PC Smith told the hearing: In hindsight it was wrong, but at the time I didnt see the potential harm because other traffic officers knew I did presentations on road safety to outside agencies. I didnt think there would be a problem.Chairing the panel, South Yorkshire Assistant Chief Constable Ingrid Lee said PC Smiths actions were an intrusion of privacy and showed a complete disregard for data protection and police responsibilities.
What Is the Use of the Number Plate Recognition System
What Is the Use of the Number Plate Recognition System
In the world of today, where the technology is constantly evolving, it is hard to keep a track of the various crimes and thefts that are happening. Especially when it comes to vehicle theft, it is often very difficult to track down vehicles, which are stolen all of a sudden, and they can never be easily recovered.In the year of 1976, a new technology evolved from behind the scene and it was known to be the ANPR or the automatic number plate recognition system. The ANPR or the automatic number plate recognition system is today used for many tasks as in synchronization with cameras and mobile phones. Several objects of lighting such as the Appian strobe light etc is used with the technology of the number plate recognition.The number plate recognition system is used for many a reason. Firstly, it is often used for collection of electronic toll taxes and also for maintaining the parking laws, rules and regulation. Secondly, in case of maintaining the traffic rules such as taking the details of the driver with the car who is driving above a particular speed limit can easily be executed by using the ANPR technology.The Appian strobe light in this case is a wonderful piece of technology, which is particularly used for surveillance purposes. The Appian strobe light is particularly used in high security areas and also by several police vehicles in maintaining the traffic laws.The ANPR or the number plate recognition technology is now a day used by several countries such as by the England, Scotland, Ireland, Germany etc. In these countries, the technology has become quite famous in no time and for this reason, several companies have come up offering products related to patrol and surveillance, which are particularly based on the ANPR technology.The automatic number plate recognition may be an instant hit with the police of various countries and in areas where high security and surveillance is required, however, such a system have got its own disadvantages.Firstly, in case of the ANPR or the automatic number plate recognition system, the images of the number plate or of any object which is taken by using the optical character reader technology may get blurred mainly due to the reason of motion blurring for which the picture seems to be hazy when uploaded in the database.Secondly, the technology often uses low-resolution images for which the images are not actually visible properly in every case.
License Plate Recognition System - Alerts on Stolen Vehicle
License Plate Recognition System - Alerts on Stolen Vehicle
Automatic number plate recognition (ANPR) is a group supervision method that uses optical character detection on images to examine the license plates on a vehicle. Licence plate recognition can be used to store the images that have been captured by the camera and the text of the number plate. Some of the systems can even store the photographic image of the driver of the vehicle. This technology is used in safety and traffic application worldwide. License plate recognition technology and ANPR has gained popularity in security and traffic applications as it is based on the fact that all vehicles have a license plate and there is no need to install any additional tracking apparatus. The main advantage is that the system stores the image record for future references. The system uses lighting (such as Infra-red) and a camera to take the image of the front or rear of the vehicle which is then analyzed by image-processing software, which extracts the image and the plate information. This data is then used for enforcement or record collection and maintenance. License plate recognition system or Automatic number plate recognition systems have the following components: 1. License plate capture camera - which captures the images 2. Lighting mostly infra-red, which the driver cannot recognize 3. Framework that is a connection between the image capturing unit and the computer and the software 4. A computer or PC which runs the system 5. The software that is used by the system. 6. The proceedings are recorded on a database which includes the images of the license plate and the driver face if that option is present in the system. 7. The system also uses other hardware including an automatic license plate reader. Car Detector has two different models or variations: 1. Fixed Camera LPR systems: CarDetector records and informs the concerned authorities regarding any unauthorized vehicles that travel through the chosen security zone, even if the vehicle is moving. The system records the time of detection, the plate number and image and the entire car image if required. 2. Mobile LPR Systems (CDMS): This is designed for mobile law enforcement vehicles. The system automatically detects the vehicle and extracts the plate image, which is then analyzed and matched with the existing database. This helps the police in detecting stolen or suspect vehicles.
What is automatic number-plate recognition?
What is automatic number-plate recognition?
Automatic number-plate recognition (ANPR) is a technology that uses optical character recognition on images to read vehicle registration plates to create vehicle location data. It can use existing closed-circuit television, road-rule enforcement cameras, or cameras specifically designed for the task. ANPR is used by police forces around the world for law enforcement purposes, including to check if a vehicle is registered or licensed. It is also used for electronic toll collection on pay-per-use roads and as a method of cataloguing the movements of traffic, for example by highways agencies. 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 day or night.ANPR technology must take into account plate variations from place to place. Concerns about these systems have centered on privacy issues, such as government tracking citizens' movements, misidentification, high error rates, and increased government spending. Critics have described it as a form of mass surveillance.Components The software aspect of the system runs on standard home computer hardware and can be linked to other applications or databases. It first uses a series of image manipulation techniques to detect, normalize and enhance the image of the number plate, and then optical character recognition (OCR) to extract the alphanumerics of the license plate. ANPR systems are generally deployed in one of two basic approaches: one allows for the entire process to be performed at the lane location in real-time, and the other transmits all the images from many lanes to a remote computer location and performs the OCR process there at some later point in time. When done at the lane site, the information captured of the plate alphanumeric, date-time, lane identification, and any other information required is completed in approximately 250 milliseconds.[citation needed] This information can easily be transmitted to a remote computer for further processing if necessary, or stored at the lane for later retrieval. In the other arrangement, there are typically large numbers of PCs used in a server farm to handle high workloads, such as those found in the London congestion charge project. Often in such systems, there is a requirement to forward images to the remote server, and this can require larger bandwidth transmission media. Technology ANPR uses optical character recognition (OCR) on images taken by cameras. When Dutch vehicle registration plates switched to a different style in 2002, one of the changes made was to the font, introducing small gaps in some letters (such as P and R) to make them more distinct and therefore more legible to such systems. Some license plate arrangements use variations in font sizes and positioning—ANPR systems 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. The cameras used can be 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. Technology ANPR uses optical character recognition (OCR) on images taken by cameras.

The cameras used can be 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. Algorithms The license plate is normalized for brightness and contrast, and then the characters are segmented to be ready for OCR. There are seven primary algorithms that the software requires for identifying a license plate: Plate localization – responsible for finding and isolating the plate on the picture.Plate orientation and sizing – compensates for the skew of the plate and adjusts the dimensions to the required size. Normalization – adjusts the brightness and contrast of the image.Character segmentation – finds the individual characters on the plates.Optical character recognition.Syntactical/Geometrical analysis – check characters and positions against country-specific rules.The averaging of the recognised value over multiple fields/images to produce a more reliable or confident result. Especially since any single image may contain a reflected light flare, be partially obscured or other temporary effect. The complexity of each of these subsections of the program determines the accuracy of the system. During the third phase (normalization), some systems use edge detection techniques to increase the picture difference between the letters and the plate backing. A median filter may also be used to reduce the visual noise on the image.
ANPR(automatic number plate recognition)
ANPR(automatic number plate recognition)
ANPRWhat is ANPR?by:Shenzhen TGW Technology Co.,LtdAutomatic number Plate Recognition (ALPR) is a technology that can detect the Vehicle on the monitored road and automatically extract Vehicle License Plate information (English letters, Arabic Numbers and Plate color) for processing. License plate recognition is one of the most important parts of modern intelligent transportation system. Based on digital image processing, pattern recognition, computer vision and other technologies, it analyzes the vehicle images or video sequence taken by the Anpr camera to obtain the unique license plate number of each vehicle, thus completing the recognition process. Parking fee management, traffic flow control index measurement, vehicle positioning, car theft, automatic superhighway overspeed supervision, red light electronic police, highway toll station and other functions can be realized Because of a serious of follow-up processing . It is important for maintain traffic safety, fighting crime,prevent traffic jam and realize traffic automation management.Common application scenarios of ANPR1.ANPR in fighting crime    In fact, we can pinpoint the culprit of many traffic violations or other crimes by tracing to the license plate. Many intersections are equipped with a red light violation detection system, and the most important part of this system is intelligent number plate recognition system modules, the system record the number plate of vehicle , and then analysis which are suspicious vehicles according to Database comparison, determine illegal information, thus reducing the illegal behavior, control the status of the traffic on the road to ensure safety.Countries around the world are actively using ANPR to combat crime.On April 24, 2015,it was announced that Victoria Police to consider implementing $86 million live video ANPR system for patrol carsin November 2014, it was announced that The Royal Malaysian Police (PDRM) was to employ an Automated Number Plate Recognition(ANPR) system to identify vehicles with foreign registration plates with unsettled summonsesOn December 20, 2018, the local authority of Redbridge Announced that  £1.5m ANPR cameras installed to fight crime.Automatic number plate recognition software is proving invaluable to the Huntly police force.Within four hours of using the ANPR equipment last week, the team of eight stopped over 25 vehicles, including a car which had been stolen by knifepoint in Northland.2.anpr in parking lot management     Nowadays, more and more parking lots have improved access to ANPR to improve management efficiency. The traditional parking system cannot meet people's needs because of the high labor cost and low management efficiency. The parking lot managers are planing to update the traditional parking systems into smart parking systems      The traditional parking system can be modified by the automatic number plate recognition (anpr) technology. The ANPR camera captures the vehicle information and the image of the person clearly, so that the owner can enter and exit the parking lot without stopping. It can also monitor the running status of all online devices, realize equipment fault pre-discovery, self-repair, query various report functions in real time, and provide customers with on-site information in the form of multiple pictures, with real-time query charge amount, the system breaks through the region. Sexual restrictions have enabled remote management across the country. The parking lot charging system is charged automatically and supports the current popular mobile payment or login to a special parking app for payment. The whole process is fast and convenient.       At present, the traditional parking lot management system is prone to cause congestion during the peak hours of commuting. The traffic efficiency is extremely low because of the simple function of the system. Traditional parking lot does not have the functions of helping the owner to find a parking space, finding a car and paying a fee quickly. Manual charging also leads to capital loopholes, makes difficulty in collecting money for change, etc. it is necessary to install a separate database and front-end display for the parking lot during installation. The ANPR system adopts a fully automatic computer management mode. From the exit of the parking lot to the gate and then to the management center, all of them are maneged by the automatic control computer to make it convenient to manage. ANPR decrease the time we spend on vehicle entering the parking lot and leaving the parking lot. And it can easily realize unmanned operation at the entrance and exit, and automatically charge, which can greatly save costs. Therefore, the intelligent parking system that can meet the needs of the management and the owners has very high potential, and the future development prospect is very broad.Sorts of ANPR SYATEM    The basic hardware configuration of a license plate recognition system is composed of A ANPR camera, master controller, acquisition card and lighting device. The software is composed of an image analysis and processing software with license plate recognition function and a background management software to meet specific application requirements.License plate recognition system has two sorts of products, one is a combination of hardware and software, or the realization of hardware recognition function module, forming a full hardware license plate recognition, such as DSP. Another sort is open software and hardware system, that is, hardware adopts standard industrial products, software as embedded software. Both the two product formats have advantages as well as disadvantages. The advantage of the open system is that the hardware adopts standard industrial products, and the operation and maintenance are easy to grasp. The purchase of spare parts can be obtained from any manufacturer, and there is no need to worry about the permanent failure of products or procurement difficulties due to the failure or shortage of supply of one manufacturer. The integrated hardware and software products make it easier for users to operate and control the products. For later maintenance debugging is also easier to grasp.Anpr working process    Automatic number plate recognition is a pattern recognition technology that USES dynamic video or static images of vehicles to automatically recognize license number and license color. Its hardware base generally includes trigger equipment (monitoring whether the vehicle enters the field of vision), camera equipment, lighting equipment, image acquisition equipment, processor (such as a computer) that recognizes the license plate number, etc. Its software core includes license plate positioning algorithm, license plate character segmentation algorithm and optical character recognition algorithm. Some ANPR systems also have the ability to determine whether there is a car by using the video vehicle detection techno. A complete license plate recognition working process(as shown in figure ) should be include of vehicle detection, image acquisition, license plate recognition and other parts . When the vehicle detection part detects the arrival of a vehicle, the image acquisition unit is triggered to collect the current video image. The license plate recognition unit processes the image, locates the license plate position, then separates the characters in the license plate for recognition, and then output the license plate number.ANPR system Technical indicators    There are three indexes to evaluate a number plate recognition system: recognition rate, recognition speed and background management system. Of course, the premise is that the system should be able to operate reliably.1.ANPR Recognition rate    Whether a ANPR system is practical or not, the most important index is the recognition rate. The international traffic technology has made the special identification rate index elaboration, the request is 24 hours all-weather brand accurate identification rate above 95%.In order to test the recognition rate of a number plate recognition system, it is necessary to install the system in a practical application environment, operate 24 hours a day or more, collect license plates of at least 1000 natural traffic flows for identification, and store license plate images and recognition results for retrieval and viewing. Then, it is necessary to get the image of the actual passing vehicle and the correct result of manual identification. Then the following recognition rate can be calculated:1. The identification rate of natural traffic flow = the total number of correct identification of the full plate/the total number of actual passing vehicles2. The percentage of identifiable license plates = the total number of license plates correctly read by human/the total number of vehicles actually passed3. The correct recognition rate of all plates = the total number of license plates correctly recognized by all plates/the total number of license plates manually read. These three indicators determine the recognition rate of license plate recognition system.2.ANPR  Recognition speed    Recognition speed determines whether a license plate recognition system can meet the requirements of real - time application. A system with a high recognition rate, if it takes a few seconds or even minutes to recognize the result, will not be practical because it cannot meet the real-time requirements in practical applications. For example, speed is a powerful way to reduce travel time and avoid lane congestion in an application that USES license plate recognition to reduce travel time.The speed of identification proposed by international traffic technology is less than 1 second, the faster the better.3.ANPR Background management    The background management system of a license plate recognition system determines whether the license plate recognition system is useful. It is important to keep in mind that it is impossible to achieve a 100% recognition rate because the license plate is defaced, obscured, obscured, or the weather may be bad (snow, hail, fog, etc.). The functions of the backend management system should include:    1. Reliable storage of identification results and vehicle image data, which can protect image data from loss when the multi-function system operation makes the network error-prone, and facilitate manual investigation afterwards;    2, effective automatic alignment and query technology, the recognized license plate number with the database of thousands of license plate number automatic alignment and alarm prompt, if the license plate number is not read correctly when the use of fuzzy query technology to obtain the relative "best" comparison results;    3, a good license plate recognition system for network operation, but also need to provide real-time communication, network security, remote maintenance, dynamic data exchange, automatic database update, hardware parameter Settings, system fault diagnosis.  How to choose ANPR provider1.Attaches great importance to stability    With the improvement of product algorithm and industry technology, integration is not an important topic for a long time, but the most important point at the present stage is "stability". Stability is defined as: within a given speed range, the accuracy must be achieved without excessive error due to external environmental influences.For example, a license plate system that is more than 90 percent accurate during the day, down to 80 percent in the evening and 70 percent at night is more difficult to integrate than a license plate recognition system that is on average 70 percent accurate throughout the day. Because the user might think, now that the recognition rate of 90% during the day, the all-weather only reasonable accuracy is 90%, this specification does not include strange environment interference (torrential rain, hail, fog, sections, etc.), and set up the environment limit (, big wind shake height limit restrictions, it is not easy to artificial damage, etc.). 2.Product testing    Almost every company claims to have high recognition rate, but in order to avoid later because both sides cognitive difference of product, and to each other, the responsibility of dysfunctional users in purchasing the license plate recognition system, as well as for product testing, and test had better more than two weeks time, compare results can determine whether "exaggerated". Because of the changeable environment, two weeks should be able to grasp about 80% of the conditions that may affect the identification rate of the field. If you only measure it for a day or even a few hours, you cannot understand it.     In addition, since license plate recognition is a "system", the hardware and software architecture will certainly affect the "present results". As to what kind of software and hardware are suitable for what kind of environment, it must be different from environment to environment, because different application environments may not have the same requirements on identification rate, and this must be accumulated by experience.Although there are a variety of license plate recognition system on the market, the use of the product and structure, can save a lot of wasted money and time, but more importantly, the project and system integrators need to cooperate with and understand, rather than blindly focus on a brand is better, cheaper, nothing is cheaper.    In addition, whether the license plate recognition system can make the most use of the software technology, the camera and the field construction ability, also have a great deal to do. Users may request the manufacturer to the scene after the exploration, the paper puts forward establishing planning, the assessment should set up the first place, using an Angle, whether you need to set up auxiliary light source, etc., offer again, by these actions, in addition to assess in advance ability and users themselves can also achieve product learning and education training, management, in the future will be more clearly know the restrictions on the use of the products and the relevant measures. More info in wikipedia
How  license plate recognition system work
How license plate recognition system work
license plate recognition system work followAs one of the important components in the intelligent transportation system, the automatic license plate recognition technology has been widely used in urban road monitoring, highway toll collection and monitoring, community and parking lot entrance and exit management, public security security card, etc. hot spot.The license plate recognition system is equipped with digital camera equipment and computer information management system and other software and hardware platforms. Through the collection of vehicle images, advanced image processing is adopted. Pattern recognition and artificial intelligence technology find the position of the license plate in the image, extract all the character images that make up the license plate number, identify the characters, letters and numbers in the license plate, and finally give the real number of the license plate.The license plate recognition is the process of sequentially realizing the license plate location, license plate character segmentation and license plate character recognition algorithm of the car image. The license plate location is to extract the license plate image from the image containing the car and the background, the input is the original car image, and the output is the license plate image.The character segmentation of the license plate is to divide the characters from the license plate image by preprocessing, geometric correction, etc. of the license plate image, and divide it into individual characters. The input is the license plate image obtained after the license plate is positioned, and the output is preprocessed and geometric. A set of individual character images obtained after correction, and the dot matrix data of each character is obtained. Character recognition is to extract character feature data from a single character dot matrix data in turn, and give a recognition result.by:Shenzhen TGW Technology Co.,Ltd
