Forest fire detection, prevention and control method based on unmanned aerial vehicle

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...

Problems solved by technology

The technology disclosed in patent CN102496234A is "when the fire source point in the forest is found, use the infrared camera on the UAV to capture it, and send the GPS position of the UAV to the fire center through satellite communication", whoever finds the fire source point ? How to find the source of fire? Can it automatically identify and extract the fire source? There is no detailed description in the patented technology, and it is impossible to automatically identify the fire area, spread range and development trend. The technology disclosed in the patent is very poor in practicability

In addition, the disclosure is limited to the functions of image collection, analysis and forecasting. By the time people receive the signal to find the fire point and take preventive and control measures, the fire may have spread
