Traffic Signs Localisation and Recognition Using A Client-Server Architecture

The detection and recognition of Traffic Signs (TSs) by smart vehicles is of great interest. In this paper, we present a novel TSs localisation and recognition system using client-server architecture. To the best of our knowledge, this is the first architecture that uses non vision-based techniques to detect and recognise TSs. To discover TSs in lanes using our architecture, each travelling vehicle (known as client in our architecture) begins by sending a request, which contains its geographical position, to the data server. This server then sends all nearby TSs, found within a given radius in the lane, to the requester. Finally, we apply a filtering algorithm to select appropriate TSs from the previously found set of TSs. Our system can be used in a conjunction with a traditional vision-based system to further increase the accuracy of the whole system.
