LILIN ANPR license plate recognition solution

Automated Number Plate Recognition, abbreviated as ANPR, is one of LILIN's foremost software products. ANPR is a type of OCR (optical character recognition) technology, to read automatically the registration number and characters of vehicles from digital pictures. Reading the registration number means transforming the pixels of the digital image into the text of the number plate. LILIN ANPR system allows versatile & client-specific applications such as comparison of number plates with a Blacklist, Whitelist, and Exclusion List. The setup of Blacklist is to avoid unauthorized vehicles attempt accessing the premises by sending a pop-up warning window to users through LILIN ANPR solutions. Whitelist is mainly for access control. In addition to Blacklist and Whitelist, users can also set up an Exclusion List, is featuring to avoid misreading frontal vehicle brand logo as registration plates.

Not only users can setup various lists for all kinds of license plate reading applications, but LILIN also offers “Recognition Rate Filtering” function to minimize the chances that unclear images / motion blur due to vehicle moving. With LILIN ANPR solutions, users can set up their default total length and font size of plate numbers and letters in order for receiving high recognition rate.

Types of License Plates
In general, registration license plate numbers have Reflective and Retro-reflective two types of plate presentations. Reflective form of registration plates are mostly being adopted in majority of European countries and the visibility & recognition rate are higher than the retro-reflective plates. For retro-reflective plates, it is highly recommended to either install an additional infrared IP camera or exterior light sensor to complement the insufficient lighting circumstance, and further increasing its recognition rate.
