With the continuous development of afforestation, the area of forest land and the volume of forestry reserves are increasing year by year, and fire prevention is a top priority for forestry development. Forest fires are one of the most important forestry disasters in the world, occurring in a certain number of cases every year, causing significant losses of forest resources and global environmental pollution. Forest fires are characterized by suddenness, randomness of disaster occurrence, and the ability to cause huge losses in a short period of time. Therefore, once a fire occurs, it is necessary to take measures to fight the fire at a very fast speed, whether the fight is timely, whether the decision-making is appropriate, the important reason depends on the behavior of the forest fire is found in a timely manner, whether the analysis is accurate and reasonable, whether the decision-making measures are appropriate. For this reason, efforts are being made at home and abroad to prevent, reduce and control forest fires.

The application of infrared thermal imaging technology in forest fire prevention is crucial, providing an efficient, non-invasive method to detect and monitor fires, which can build a three-dimensional monitoring network for forest fire prevention that is round-the-clock, all-weather, and full-coverage. Infrared thermal imaging technology can quickly scan a large area of forest area, detect the high temperature area generated by the fire, to achieve early fire detection; through continuous monitoring of temperature changes in the fire area, infrared thermal imaging technology can help fire prevention personnel to determine the development trend of the fire, and formulate effective fire-fighting strategies; infrared thermal imaging technology can real-time observation of the thermal distribution around the fire line, and quickly find out the direction of the fire and the spreading of the fire line Direction, for the commander to provide an important reference; infrared thermal imaging technology can be in the night, complex terrain or smoke and other poor conditions for efficient detection, improve the accuracy and timeliness of fire detection; infrared thermal imaging technology can be realized in long-distance range detection, so that fire prevention personnel can be safely away from the danger zone, and at the same time for fire monitoring; infrared thermal imaging technology can be integrated into the intelligent early warning system, with the over-temperature detection system, visible light cameras and other equipment to work together. system, visible light camera and other equipment work together to provide comprehensive fire monitoring and analysis.

The application of infrared thermal imaging technology in forest fire prevention not only improves the accuracy and timeliness of fire early warning, but also reduces the losses caused by fire, providing important technical support for the protection of forest resources and ecological environment. With the continuous development of technology, the role of infrared thermal imaging technology in the field of forest fire prevention will become more and more important.
