The invention provides an unmanned aerial vehicle guided multi-vehicle cooperation fire extinguishing method. The method comprises the following steps that a ground control terminal is started, an unmanned aerial vehicle performs flight search along a search
waypoint and establishes ground two-dimensional map information, a
fire point is searched and accurately positioned, spatial position information of the
fire point, the unmanned aerial vehicle and all fire-fighting unmanned vehicles is calculated and marked, after path planning, all the fire-fighting unmanned vehicles travel in a formation mode to advance towards the
fire point, autonomously avoid obstacles and establish a three-dimensional sparse
point cloud picture, whether the fire-fighting unmanned vehicles advance or not is judged through a temperature sensor, a fire extinguishing task is started when the fire-fighting unmanned vehicles are close to the fire point, and after the fire extinguishing task is completed, the unmanned aerial vehicle and all the fire-fighting unmanned vehicles return along the original path. The invention further provides a multi-vehicle cooperation fire extinguishing
system suitable for the method. The multi-vehicle cooperation fire extinguishing
system comprises the unmanned aerial vehicle, the plurality of fire-fighting unmanned vehicles and the ground control terminal. According to the unmanned aerial vehicle guided multi-vehicle cooperation fire extinguishing method and the fire extinguishing
system thereof, the time required by the unmanned vehicles to arrive at the fire point can be greatly shortened while the large-
range searching and accurate positioning of the position of the fire point are ensured, and the efficiency of completing the fire-fighting task is improved.
