thermal camera imaging technology has applications in both military and civilian applications. It originally originated from military use and gradually turned to civilian use. In civilian use, it is generally called a thermal camera, which is mainly used in research and development or industrial testing and equipment maintenance. It is also widely used in fire protection, night vision, and security. In layman's terms, a thermal camera converts the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent different temperatures of the measured object.
