Forest fires are one of the significant disasters in global forestry, occurring in certain numbers every year, resulting in substantial losses to forest resources and global environmental pollution. They are characterized by suddenness, randomness in occurrence, and the potential to cause massive damage in a short period. Therefore, once a fire alarm is triggered, it is imperative to take firefighting measures at an extremely rapid pace. The timeliness of the extinguishing efforts and the appropriateness of the decision-making largely depend on the timely detection of fire behavior, accurate and rational analysis, and the suitability of the decision-making measures. To this end, efforts are being made both domestically and internationally to prevent, reduce, and control forest fires.

Infrared thermal imaging technology plays a crucial role in forest fire prevention, providing an efficient, non-invasive method for detecting and monitoring fire conditions. It enables the establishment of a comprehensive, round-the-clock, all-weather, three-dimensional forest fire monitoring network. Infrared thermal imaging can quickly scan large forest areas, detect high-temperature zones produced by fires, and achieve early fire detection. By continuously monitoring temperature changes in the fire area, infrared thermal imaging helps firefighting personnel assess the development trend of the fire and formulate effective firefighting strategies. The technology can observe the thermal distribution around the fire line in real time, quickly identify the direction and spread of the fire line, providing important references for commanders. It can efficiently detect fires under adverse conditions such as at night, in complex terrains, or in smoke, enhancing the accuracy and timeliness of fire detection. Infrared thermal imaging allows for long-distance detection, enabling firefighting personnel to safely stay away from dangerous areas while monitoring fires. It can be integrated into intelligent early warning systems, working in conjunction with systems for detecting high temperatures, visible light cameras, and other equipment 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 warnings but also reduces the damage caused by fires, providing important technical support for the protection of forest resources and the ecological environment. As technology continues to advance, the role of infrared thermal imaging in the field of forest fire prevention will become increasingly important.
