Licence Plate Recognition - ANPR System

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.
ANPR can be used to store the images captured by the cameras as well as the text from the license plate. Systems commonly use infrared lighting to allow the camera to take the picture at any time of day or night.

How ANPR Works?

For license plate recognition to work, your camera needs a few specific things:

• The angle of the camera is extremely important, because a camera that's installed too high cannot see the license plate
• The distance from the camera to the car must also be considered - while a camera may be able to zoom in quite a distance, you want to minimize the distance between camera and car
• Lighting is also important - whether you install lights or use the camera's built-in IR, you will need additional lighting at night
• The speed of oncoming traffic must be low enough that the camera has enough time to focus on the license plate

In addition, you'll need to pay attention to the quality of the image. To be used as legal evidence, your video may need to meet standards set by your local law enforcement; one requirement might be that the captured license plate image be at least 15 pixels tall, to ensure clarity.

Web Camera Pro application uses data vision theory to identify objects within video, search through catalogues of images, and extract information out of images.

Object detection deals with detecting instances of semantic objects of a certain class (such as a dog, a human, or a car.) in digital images and videos.

Web Camera Pro is using Computer Vision to understand everything that happens on your cameras and sends smart and flexible video surveillance alerts.

Custom-tailored ALPR systems are popular worldwide for aiding with many related processes.

Among the applications of ALPR that you can consider for your business, are:

• Manage parking facilities. Controlling gates with the help of an automated solution can facilitate monitoring vehicle entry/exit and payment operations. Also, some listed vehicles can be restricted from parking.
• Electronic toll collection. Custom ALPR systems can be used to supervise toll roads, bridges, tunnels, etc., and to charge drivers bypassing associated manual labor.
• Access control. It will be easier to oversee entry permits at airports and places restricted for some categories of vehicles.
• Control the movement of traffic. ALPR is capable of reading number plates and collecting vehicle location data, for instance, for the needs of highway agencies.
• Receive alerts and prevent crimes. These systems send automatic notifications on capturing vehicles that are on a watch list.
• Traffic enforcement. ALPR eases exercising control over respecting traffic rules by drivers and helps capture the license plates of vehicles that go through a red light or break the speed limit.
