License Plate Recognition Software
The CARMEN® Parking License Plate Recognition Engine is a special version of the CARMEN® license plate recognition technology. It has been developed to offer an excellent solution for the growing need of parking and access control management systems.
With integration CARMEN® Parking into parking management systems, it becomes possible to automate vehicle entry to and exit from a car park or a secure zone and to use the recognised registration number for inventory management.
The usage of CARMEN® Parking with our specially designed camera set - equipped and synchronised with a IR flash - provides quick and accurate identification of vehicles 24 hours a day, 7 days a week, without human assistance or any driver co-operation.
One of the major applications of license plate recognition is parking and access control. These applications and systems have their own special requirements. In parking and access control applications recognition accuracy is a very critical issue both from the automation's and the security's point of view. However - on the other hand - vehicles have limited speed or frequently stop when their plates are being recognised.
Therefore we have developed a special version of CARMEN®, the CARMEN® Parking, to meet all the special requirements of parking and access control. We have kept the flexibility of the SDK and of course the robustness and stability of the plate recognition engine while added extra features that are useful when making the application software of a parking, car park management or access control system.
The CARMEN® Parking ANPR Engine and its SDK is a special version of our ANPR technology. It is specially designed and developed for parking and access control applications, where automatic identification of vehicles is needed.
