In the broad field of technology, thermal drone are used in many industries and are revolutionizing the way we perceive and interact with our environment. Among the different types of drones, thermal drones stand out as innovators, offering a unique perspective through infrared imaging. Let’s explore the fascinating world of thermal drones and how they are making a significant impact in various industries.
What are thermal drones?
These are unmanned aerial vehicles (UAVs) equipped with a thermal camera or specially designed sensors to detect infrared radiation emitted by various objects. They transmit images or videos in real time and show the temperature distribution of the objects or terrain they fly over.
The principle: objects emit infrared radiation depending on their temperature, with hotter objects emitting more than colder objects. A drone equipped with a thermal camera records these emissions, painting a vivid picture of the thermal landscape below.
Their applications range from drone inspections, which can detect heat loss in buildings, to search and rescue operations, where missing people can be found even in complete darkness. Let’s not forget the enormous benefits of drone agriculture, which allows farmers to easily assess the health of plants, animals and irrigation needs.
