What is LPR(License Plate Recognition) Technology?

LPR or ANPR(Automatic Number Plate Recognition) 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. LPR 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 cataloging the movements of traffic, for example by highways agencies.

License 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. LPR technology must take into account plate variations from place to place.

Advantages of LPR technology:

1. For Parking Lot Management;

2. Identify vehicle plate text and figures automatically;

3. Save labor cost and management difficulty in parking lot management;

4. Improve traffic efficiency;

5. Tickless/ cardless parking lot management;

License Plate Recognition technology (License Plate Recognition, LPR) is based on computer technology, image processing technology, and fuzzy Recognition to build the characteristics of the vehicle model, identify the vehicles' characteristics, such as Plate, model, color, etc. It can automatically extract the plate image from an image, it uses advanced image processing technology, pattern recognition, and artificial intelligence to the collected images information and processing, it can identify the license plate numbers, letters, and Chinese characters, and directly given recognition result, makes the system become a reality.
