The CARMEN® Freeflow License Plate Recognition Engine possesses all the features a high quality license plate recognition system may require:
it is highly accurate, fail safe and stable, fast and intelligent.
Meanwhile it provides the highest technological performance amongst today's license plate readers,
CARMEN® FreeFlow offers great flexibility for manufacturers and integrators of car plate recognition systems:
it can be integrated into practically any automatic number plate recognition system which needs automatic vehicle recognition.
There is no compromise.
The CARMEN® FreeFlow's Software Development Kit (SDK) makes integration of optical plate recognition extremely easy, fast and cost effective.
And the resulted image processing system will have the highest performance - both in terms of recognition accuracy and speed - of optical license plate recognition.
Features of CARMEN® FreeFlow
The CARMEN® Freeflow offers general-purpose license plate reading from digital pictures of any tpye of sources.
Whether it is a megapixel-size, 12bits/pixel high dynamic range, high resolution digital image or a 384x288 size colour CCTV video picture provided as input,
(either from file or memory) CARMEN® provides ballanced reading of car plates.
While there is a vast space for different configurations - you can freely set the working parameters of CARMEN®

Applications of CARMEN® FreeFlow
While CARMEN® Freeflow is suitable for any automatic license plate recognition system, it is mainly used in
Intelligent Transportation Systems (ITS), security systems and low enforcement systems.
The main applications are: motorway toll collection (highway toll collection), traffic analysis, weight in motion, police law enforcement,
state border control, enforcement of traffic regulations, vehicle theft prevention, assests protection,
automation and simplification of airport, harbour and warehouse logistics, security monitoring of roads and checkpoints, vehicle surveillance, etc...
As car plate recognition is the most natural way of automatic car identification, car license plate recognition can be used anywhere, where automatic,
computerised vehicle identification is needed.
