- 8. •License plate recognition (LPR) INTRODUCTION A vehicle registration plate is a metal or plastic plate attached to a motor vehicle or trailer for official identification purposes. The registration identifier is a numeric or alphanumeric code that uniquely identifies the vehicle within the issuing region’s database. Eight types of license plates are used in Pakistan. Each province and territory issues its own number plate; the federal government issues number plates for foreign diplomats and vehicles owned by the military, police and federal departments (red for foreign diplomats and green for the federal government.)Sindh’s number plates are yellow with black letters and numbers for private vehicles and Black number plates with white letters for commercial vehicles; Islamabad, NWFP, Azad Jammu and Kashmir, Balochistan
- 9. and Northern Areas have white number plates with black letters and numbers The number plates also have the province or territory’s name at the bottom. In Punjab however, number plates can be of any color the vehicle owner chooses, but the first 2 letters represent the city the vehicle is registered in. The same all over Punjab and has a sign and’ Punjab’ written on it, while the white part has the number of the vehicle. For example: •RIZ 3725, is a vehicle registered in •RIW1329, is a vehicle registered in Rawalpindi, Punjab.
- 10. MAIN CHARACTERISTICS OF INFORMATION SYSTEM LICENSE PLATE CAPTURE CAMERA License plate capture cameras are a specialized form of CCTV camera that has built in software that helps to identify and capture license plates on still or moving vehicles. The intelligent traffic modes built into these cameras allows the camera to compensate for speed, weather, and headlight issues which all make it challenging to capture a usable video that identifies license plates. AIM •To Reduce Crime and the Fear of Crime •Reduce Burglaries •Reduce Vehicle Crime •Reduce shop theft
- 11. •Reduce damage and graffiti •Reduce motorcycle / traffic related nuisance OBJECTIVES • ANPR – capitalising on what you already know MISSION Delivering superior knowledge at the point of decision STRATEGY •Work with Partner Agencies at National, Regional and Local Level to Share Assets and Data, avoid Duplication and enhance Operational Effectiveness
- 12. •Proactively maintain National support and momentum for ANPR within the Police Service, partner agencies and Government •Working with the ANPR industry, continue to develop and exploit Technology to support ANPR activities. •Promote the better collection, use and weeding of vehicle intelligence to support ANPR activity, including utilization of appropriate databases from other agencies LICENSE PLATE RECOGNITION (LPR) SYSTEM CCTV Camera Pros license plate recognition (LPR) system, provides high-resolution video monitoring and recording. Our License Plate Recognition (LPR) system is an effective video surveillance and parking lot monitoring solution. Many parking lots have a high security risk rating. It is difficult for security personnel to monitor isolated areas or levels of large lots. Most lots need effective digital surveillance systems to provide live monitoring and continuous recording. These video surveillance systems provide protection and reassurance to customers and employees.
- 13. The license plate capture system activates the LPR recognition process in two ways. TWO WAYS PROCESS LPR RECOGNITION • The first is via software video motion detection, which detects vehicles passing through the camera and illumination zone. • The second is by input / output activation, which triggers recognition and recording upon I/O activation. The system supports both camera overview and picture-in-picture modes with ease of monitoring WHY WE NEED TWO CAMERAS FOR TRAFFIC SURVEILLANCE? •The monochrome camera produces high-contrast license plate images characterized by unmatched clarity. •Simultaneously, a second camera captures color overview images of vehicles for additional video evidence. LICENSE PLATE RECOGNITION SOFTWARE
- 14. •The Geovision-LPR license plate recognition software features: •High recognition rate •High recognition speed: < 0.2 second •Supports up to 8 I/O Trigger or 4 Motion Detection lanes •Support image up to 720 x 480 (NTSC) providing higher accuracy •Integrate with GV-series DVR capture cards •Vehicle counter feature tracks number of vehicles •Camera overview for vehicle or driver The GeoVision GV-LPR license plate recognition software is an effective video security and parking / traffic monitoring solution. To provide security or allow access to customers and employees, parking lots can integrate these high efficiency digital surveillance systems with license plate recognition to enhance lots security and surveillance efficiency. GV-LPR is used with GeoVision Surveillance and License Plate Capture Cameras. LPR (License Plate Recognition) is an image-processing technology used to identify vehicles by their license plates. This technology is used in various security and traffic applications, such as gated access-
- 15. control system. The GV-LPR license plate recognition system provides high-resolution video monitoring and recording. The system uses illumination (such as Infrared) and a license plate capture camera to take the image of the front or rear of the vehicle, then the GV-LPR license plate recognition software processes analyzes the images and extracts the plate information. This data is used for enforcement, data collection, and can be used to open a gate if the car is authorized or keep a time record on the entry or exit for automatic payment calculations. The LPR system significant advantage is that the system can keep an image record of the vehicle which is useful in order to fight crime and fraud. An additional camera can focus on the driver face and save the image for identification reasons. GV-ANPR SYSTEM

- 20. •JPEG format support allows approximately 2 million JPEG images to be saved in a 160 GB HDD •Auto recycle for image storage and database backup HARDWARE At the front end of any ANPR 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 system which, often determines the overall performance. License plate capture is typically performed by specialized cameras designed specifically for the task.
- 21. 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. USE OF ANPR SYSTEMS •Section control, to measure average vehicle speed over longer distances. •Border crossings •Filling stations to log when a motorist drives away without paying for their fuel. •Traffic management systems, which determine traffic flow using the time it takes vehicles to pass two ANPR sites •Drive Through Customer Recognition, to automatically recognize customers based on their license plate and offer them their last selection, improving service to the customer. •To assist visitor management systems in recognizing guest vehicles
