Embodiment 1

[0030] A method of forest fire detection and prevention and control based on drones, the steps are as follows figure 1 Shown:

[0031] 1) Preset meteorological data in the UAV, visible light images and thermal infrared images of the monitoring area under normal conditions; preset the threshold value of thermal aberration value; threshold acquisition method: thermal infrared images of the monitoring area under normal conditions, combined with pre-set Set the meteorological data, adjust the image brightness range, which is the threshold range;

[0032] 2) Use the UAV to inspect the monitoring area and take visible light images and thermal infrared images at the same time, and record the corresponding shooting position and shooting time of the image in real time through the GPS positioning function, and at the same time transmit the data to the ground receiving station through the wireless communication network;

[0033] 3) The visible light image and thermal infrared image obta...

Abstract

The invention discloses a forest fire detection, prevention and control method based on an unmanned aerial vehicle. According to the forest fire detection, prevention and control method, the mode that visible-light images and thermal infrared images are combined is adopted, a forest fire can be judged by observing thermal image difference values of high-brightness points of the images, and fire extinguishing bags are released so as to extinguish fire head points in time or control fire behaviors primarily; accurate analysis is further conducted through a receiving station on the ground, abnormal areas missed during rough judgment conducted by the unmanned aerial vehicle can be found in time, and particularly monitoring can be achieved more effectively by forming a percentage distribution diagram of fire behavior possibility coefficients; efficiency and accuracy are high.

Description

technical field [0001] The invention belongs to the technical field of fire safety, and in particular relates to a forest fire detection and prevention and control method based on an unmanned aerial vehicle. Background technique [0002] Forest fire is one of the major disasters in global forestry, which causes heavy loss of forestry resources and large-scale environmental pollution every year. Traditional forest fire monitoring mainly adopts manual observation, remote video monitoring and satellite remote sensing. [0003] The artificial lookout method is to set up lookout posts at the commanding heights, and the on-duty personnel are on duty 24 hours a day. Due to human negligence and negligence, many fires will not be detected early, delaying the fire fighting time, and causing serious consequences. [0004] The remote video monitoring method is to build a large number of video monitoring points in the forest area. The monitoring points are equipped with cameras, and the...
