A method and system for unmanned aerial vehicle mountain fire exploration and control

Abstract

The embodiment of the present invention discloses a UAV mountain fire exploration control method and system, wherein the UAV mountain fire exploration control method preprocesses visible light images, short-wave infrared images, mid-wave infrared images and long-wave infrared images , splicing and fusion, brightness temperature inversion and other processes to obtain the fusion image and the brightness temperature value of each pixel in the fusion image, and then identify the open flame point according to the fusion image and the brightness temperature value of each pixel in the fusion image Finally, according to the location of the fire point, analyze the impact range of the wildfire and the distance between the center of the wildfire and the transmission line, determine the level of the wildfire, and give an early warning based on the level of the wildfire. Compared with the existing technology, it can effectively distinguish the open fire point and the dark fire point, and can give timely early warning according to the level of the mountain fire, which can effectively improve the detection rate of the mountain fire and the success rate of fire fighting, reduce the safety risk of firefighters, and further Ensure the safe and reliable operation of transmission lines.

Description

technical field [0001] The invention relates to the field of electrical geological exploration, in particular to a control method and system for unmanned aerial vehicle mountain fire exploration. Background technique [0002] Generally speaking, wildfires can be divided into open fires and dark fires. Open fire usually has obvious flame (flame) rising, violent reaction, strong heat radiation, and the firefighters are more dangerous when fighting. Dark fires often have no flame, commonly known as smoldering, similar to the burning of cigarettes, especially difficult to judge whether they have been completely burned, and dark fires are easy to re-ignite, so it is more difficult to fight dark fires, and the losses caused by dark fires are also greater . The high mountains and densely forested power transmission corridors in my country objectively determine the possibility of frequent wildfires in dry seasons with little rain. [0003] Many transmission lines in my country ar...

Problems solved by technology

[0005] An embodiment of the present invention provides a method and system for controlling wildfires by UAVs to solve the problems in the prior art that it is difficult to distinguish between open fires and dark fires when using UAVs to explore mountain fires in transmission line corridors and to control mountain fires. The problem that the fire image range cannot make a reasonable assessment of the disaster situation
