How to break the principle of drone thermal imaging arresting people?

As long as the objects in nature are above absolute zero (-273℃), they will continuously radiate infrared rays. Thermal imaging converts infrared radiation on the surface of an object into a visible image through an optical system, an infrared detector chip and an electronic processing system. Simply put, the principle of infrared thermal imaging is to use temperature imaging to convert invisible infrared energy emitted by objects into visible thermal images. Different colors on the thermal image represent different temperatures of the measured object.

Traditional night vision equipment relies on visible light reflected by night environment, while infrared thermal imaging is not affected by visible light, so it can see the target in complete darkness. In addition, infrared thermal imaging can penetrate smoke, dust, vegetation cover and so on. And can be used in outdoor observation, personnel search and rescue, circuit detection, floor heating detection, hotel/rental house camera detection and many other fields.

Unmanned aerial vehicles equipped with thermal imaging can break through the limitations of terrain, light and vegetation, not only help to quickly lock and catch bad guys, but also play an important role in personnel search and rescue operations.
