Nowadays,
having a car is quite necessary for the daily life of
people worldwide. In Thailand, like other countries,
there are a lot of cars on streets going in and out
office buildings; thus, to provide some degrees of
security, many traffic control applications are employed
in order to achieve the efficient management. PPA
License Plate, the license plate recognition system, is
one of the most interesting options proven to substitute
critical values in effective security. For example, it
can help tracking car thieves, drug smugglers,
terrorists, suspects or ones who break the traffic laws.
It is also seen as a promising method of enforcing toll
payment, recording the traffic-use statistics,
allocating parking spaces for specific members (access
control system) and providing parking fee management.
Besides, the advanced technology helps bring customers
and officers the senses of confidence in secure, and
increases organizational positive image.
Using Image Processing techniques, PPA License Plates
technology involves 3 major processes of capturing a car
picture, searching the plate position, and transforming
image into text data using the PPA OCR tool which is
specially designed and developed for reading the plate
labels (this tool is able to automatically transform for
image text, and seek car images and data within 1
second).

known as LPR, Automatic Number-Plate Recognition (ANPR,
