Flooding disaster oriented USV & UAV system development & demonstration

Flooding disasters have led to heavy costs including enormous property losses and casualties. The biggest challenge lies in rescue operation is the low efficiency and the high security risk of rescuers, which is also a problem focused on by this work. Unmanned system is one of the solution that replace people in the rescue operation. However, there are still some obvious defects of unmanned system that are difficult to overcome, such as the limited perspective of the Unmanned Surface Vehicle (USV) and the short flight endurance of a micro multi-rotor craft also called little Unmanned Aerial Vehicle (UAV). At the same time, they both have other advantages that the other one does not have, for instance, the long cruising ability of the USV and the broad horizons of the UAV. Thus in this paper we try to combine the superiorities of the USV and the UAV to make up for their defects, as a result, the whole system will be able to own a broad vision and a long cruising power.
