titanHz using the latest technologies that uses Optical Character Recognition
(OCR) to automatically read license plate characters. There are two types
of ALPR systems (Automatic License Plate Recognition Systems): stationary,
which uses infrared (IR) cameras at high fixed points, and mobile, which uses vehicle-mounted
IR cameras. Stationary cameras can be mounted on signs, street lights, highway overpasses
or buildings as a cost-effective way to monitor moving and parked vehicles twenty-four
hours a day. Camera software is able to identify the pixel patterns that make up
a license plate and translate the letters and numbers on the plate to a digital
format. The plate data is then sent to a database where it is compared in real-time
to a list of plate numbers that belong to "vehicles of interest". If the system
detects a match, it sends an alert to the dispatcher or other designated personnel.
ANPR systems (Automatic Number plate Recognition Systems) is used for detecting
crime through the use of intelligence monitoring. There are six primary algorithms
that the software requires for identifying a licence plate:
1.Plate localization - responsible for finding and isolating the plate on
the picture
2.Plate orientation and sizing - compensates for the skew of the plate and
adjusts the dimensions to the required size
3.Normalisation - adjusts the brightness and contrast of the image
4.Character segmentation - finds the individual characters on the plates
5.Optical character recognition
6.Syntactical/Geometrical analysis - check characters and positions against
country specific rules
Our ANPR Solutions
titanHz proposed using an ANPR systems across these sites, and in
early 2012 installed ANPR solutions at 95 of Asda's manned maximum stay car
parks. ANPR (Automatic Number plate Recognition) is an automatic surveillance method that uses optical character
recognition on images to read vehicle registration numbers. Infrared cameras record
the registration numbers of vehicles entering and exiting the car park.
