WHY LPR?

Session LPR 2License Plate Recognition

If your business is involved with surveillance, counter-terrorism, access control and

congestion charging markets…

If your customer base are police forces, local authorities, universities, gated

communities and government bodies.

Growth potential is significant due to rise in Security and Traffic initiatives. (In the US alone, a vehicle is stolen once every 26 seconds.)

WHAT is LPR?

Session LPR License Plate Recognition 7

Session LPR WHAT is LPR? 8

It is a kind of OCR (optical character recognition)

Optical Character Recognition (OCR) is the method used by a computer to convert scanned in pages of text into

electronic text documents. (definition at web)

"License Plate Recognition is the method used by a computer to convert digital images of vehicle license plates into electronic text."

The artificial neural network consists of many no-linear processing units (neuron) and numerous links between those units. Parallel and separate processing method enables this network to deal with multitudinous data simultaneously.

Key to success in license plate capture:

The quality of the license plate image!

HOW to install LPR?Used Dedicated Cameras 18

Is it possible to let the camera to capture license plates and at the same time provide

surveillance of the surrounding area?

NO!• the camera cannot deliver high-resolution

images of the license plates•The camera cannot cope with changing

environmental conditions over time

Solution: DUAL CAMERA!

Session LPR

HOW to install LPR?Properly Position the Camera 19

Ideally : At vehicle “bottlenecks” or by control points such as barriers Ideally: the license plate should be viewed from NOT more than 35 degrees Ideally: the width of the license plate should be 1/5 to 1/3 of the width of the image (min. 120 pixel)

Session LPR

HOW to install LPR?The importance of Infrared 20

How to solve the serious problems caused by glare on the license plates from factors such as headlights, sunlight and reflections from

roads?

GOOD IR lighting – day and night!

Because all visible light is cut-filtered and only IR light is used by camera!

HOW to install LPR?The suitable capture card 21

TWO ways to recognize:

With software motion detection (30 frames/sec)The LPR system monitors vehicle passing through the camera and illuminator zone constantly and analyze it autonomously

By I/O activation (15 frames/sec)I/O devices: magnetic loop detector, overhead laser scanner, or

infrared sensor, which output their command through RS 232/485
