Number Plate Recognition (ANPR/LPR)
and Counting Cars

Integration of CARRIDA software engine
into Bulgarian LPR solution

Intelligent Traffic Monitoring System for Bulgarian Roads

Reliable traffic monitoring systems for vehicle identification are in demand all over the world. The Bulgarian company atto-Systems, a provider of industrial image processing systems, developed a high-value-for-money comprehensive license plate recognition (LPR) solution for the Bulgarian market. The automatic number plate recognition (ANPR) software engine CARRIDA plays a key role in this clever combination of OEM components and customer-specific software.

In October 2015, several hundreds of these intelligent transportation systems were tested at 200 different locations across Bulgaria’s road network.

The systems allows

• a continuous traffic count
• vehicle classification into 10 categories (e.g. passenger car, motorbike, truck)
• speed detection
• number plate recognition for vehicle speeds up to 200 km/h in up to two traffic lanes
• recognition accuracy of more than 95 % for Bulgarian number plates.

The ITS systems were installed on purpose-made gantries and triggered by a ground contact in the road. At the heart of this system is the CARRIDA ANPR software.

Reliable number plate recognition with CARRIDA Software Engine

atto-Systems has complemented the CARRIDA software solution by adding a number of features to create a customer-specific all-in-one solution:

- Pre-selection of image areas that likely contain a license plate. Only the cropped image portions are sent to CARRIDA, resulting in a more than 100 % faster image evaluation
- Processing routine to handle peaks in demand
- Blacklist/whitelist option
- Streamlined user interface for easier setup of traffic lanes and parameterisation
- Maximum functionality in all light and weather conditions. For this purpose, atto-Systems developed a special lighting solution and has integrated a heater, ventilation as well as temperature and moisture sensors into the weather-proof outdoor housing
