In many cases car number plate recognition systems are needed not only at stationary, but also at mobile objects. As examples we can name guard services, security service cars and automobile inspection, service cars.
Such systems are indispensable for carrying out the investigation and search operations, forthwith car thefts and looking for particular cars during anti-terrorist operations.
A car is generally equipped with two wide-angle surveillance cameras oriented along and opposite the move direction. Cumulative observed angle depends on the camera model and comprises from 240° to 300°. Image processing algorithms, embedded into Overseer Mobile, automatically compensate wide angle distortions, thus, capture and recognition of the numbers decreases by less then 5% in comparison with fixed versions.
The highest effect from Overseer Mobile system is achieved under mass introduction and following gathered data analysis. For example, having put over the city map a layer with patrol car routes and car number samplings, fixed by the system, it is possible to analyse the routes of cars uncovered. Embedded video data and journal archiving means allow storing gathered data and implementing flexible data search, while processed data limits are practically unrestricted and are defined by hardware platform, where the analytical complex is deployed.
