An Omnidirectional Vision System for Bus Safety Surveillance

Sudden brake seems to be unavoidable in driving practice to prevent from accidence. The sudden brake may often cause falling risks to on-board passengers in public transport and even threaten the lives of the senior. Thus, this paper presents an omnidirectional vision system to assist bus drivers in ensuring the safety for passengers. To this end, we configure an auxiliary camera in the boarding gate to recognize the age of passengers and an omnidirectional camera on the ceiling of the bus to detect and track the passengers. Their trajectories and positions are mapped into a bus layout, together with their age information transferred from the auxiliary camera. This bus layout is shown on a small display in front of bus drivers. Instead of looking to the mirror to guess and gather information of passengers, the driver can collect such necessary information for safe driving. We set up experiments on a real bus and demonstrate the system by preliminary results.
