Exploiting CCTV Camera System for Advanced Passenger Services On-board Trains

This work proposes to exploit the on-board closed-circuit television (CCTV) security system to enable advanced services not only for surveillance, but also for safety, automatic climate control, e-ticketing. The new system has minimal hardware and installation cost overheads, since it exploits the already installed CCTV cameras. In addition, for each wagon, an embedded acquisition and processing node (EAP) is used, composed by a video multiplexer, and by a digital signal processor that implements algorithms for advanced services such as: smoke detection, to give an early alarm in case of a fire, or people detection for people counting, or fatigue detection for the driver. The information is then transmitted from each EAP node to the train information system. The final terminals can be the tablets of the train staff, and/or visualization displays in each wagon in case of fire alarms for the passengers.
