What is thermal drone and how does it work?
What is a Thermal Drone and How Does it Work?
A thermal drone, also known as an infrared drone, is a type of drone equipped with a thermal camera that can detect heat signatures and create a visual representation of temperature variations in the environment. This technology can be used for a variety of applications, such as search and rescue, surveillance, and industrial inspection.
Thermal drones work by using a thermal camera to capture infrared radiation emitted from objects in the environment. Thermal cameras have a special lens that focuses the infrared radiation onto a detector array made up of many individual detector elements called microbolometers. Each microbolometer measures the temperature of the radiation that it receives and generates an electrical signal proportional to the temperature.
The signals from all the microbolometers are then processed by a computer, which converts them into a visible image. In the image, different colors or shades represent different temperatures, with the hottest areas being displayed in bright colors like red, and the coolest areas in darker colors like blue.

Thermal Imaging vs. Night Version
Thermal Imaging vs. Night Version
The main difference between night vision cameras and thermal imaging cameras is what they can see. Night vision cameras are like normal cameras in that they both see things in terms of reflected light, but night vision cameras need very little light or they will provide their own light. Thermal imaging cameras do not see reflected light, but thermal energy.
One disadvantage of using night vision cameras is that their images are not as clear due to poor contrast. Contrast is the difference in colors between objects that makes them stand out from each other. In the dark, everything is pretty much the same color, so it can be hard to see anything despite the magnified light. These cameras also have a shorter range because their visibility decreases the further they get from a light source.
Thermal imaging cameras don't need light to see, so poor contrast isn't a problem. In contrast, thermal imaging cameras produce high-contrast images due to their ability to detect differences in heat. Compared to night vision cameras, thermal imaging cameras are more effective because they can be used in complete darkness and harsh weather conditions.
What is a Thermal Drone Used for?
What is a Thermal Drone Used for?
As thermal sensors become more technologically advanced and accessible, many drone applications are emerging in different industry sectors. To help you understand how this technology can help professionals around the world, we will list below the main applications of drones with thermal cameras:
Solar Farm Inspections
Thermal drone inspection detects faulty or malfunctioning solar panels by detecting variations in temperature. During an inspection, the drone's thermal camera captures images of the panels and creates a thermal map of the solar field. Any panel producing less heat than surrounding panels may indicate a problem.
The thermal images also reveal shading areas, which can reduce panel efficiency. Technicians can use this information to make necessary adjustments and maximize energy output.
Powerline Inspections
Drones with thermal cameras are used in powerline inspections to detect potential faults and identify areas that need maintenance. By detecting abnormal heat on powerlines and related infrastructure, inspectors can take proactive measures to repair or replace damaged components, preventing potential damage and reducing the risk of outages.
Thermal drones can also be used to inspect transformers and assess the overall health of powerline infrastructure. Overall, the use of these drones in powerline inspections improves the safety and reliability of power distribution systems.
Wildlife Hunting
Commercial drones with thermal cameras are increasingly being used in hunting to locate and track animals. During a hog hunt, thermal imaging drones can be used to scan large areas of land quickly and efficiently. The thermal cameras can detect the heat signatures of hogs or deers, even in dense vegetation or low-light conditions. Once hogs are detected, hunters can use the information from the drone to move in and locate the animals.
The use of infrared drones can increase the chances of a successful hunt and maintain a safe distance while tracking the animals through challenging terrain.
Roof and Building Inspections
Drones with infrared cameras are used in roof and building inspections to detect areas of heat loss, moisture intrusion, and structural defects. The drone's thermal camera captures infrared radiation emitted by objects, which allows it to create a heat map of the building's surface.
This heat map can help identify areas where insulation is lacking, where leaks or moisture are present, and where structural defects may be causing heat loss. By detecting these issues early, thermal drones can help prevent costly repairs and improve energy efficiency in buildings.
Precision Agriculture and Livestock
Unmanned aircraft are popular in precision agriculture, performing various functions from pre-planting to harvesting, such as localized fertilization and pest control. Thermal mapping drones monitor soil and plant temperature and are useful for long-term vegetation and soil monitoring. NDVI indices relate plant spectral response to the infrared and visible spectrum and are widely used in agriculture to identify plant health, water and nutritional stress, pests, and fertilization needs.
Ranchers use drones with thermal cameras to monitor pastures, grazing, and locate animals. Aerial mapping with thermal cameras is becoming more accessible, with drones being used in various applications in agriculture and livestock management.
Refinery and Pipeline Inspections
Thermal drones are used in refinery and pipeline inspections to detect anomalies in equipment and infrastructure by capturing thermal images of the area. The drones can quickly cover large areas, allowing inspectors to identify potential issues such as leaks or hot spots in pipelines or tanks.

This information can be used to schedule maintenance and repairs before more significant problems arise, reducing the risk of accidents and downtime.
Search and Rescue
Thermal drones are used in search and rescue to locate missing persons or survivors by detecting their body heat signatures. The drone's thermal camera can detect temperature differences and create a visual representation of the environment based on the heat emitted by objects or individuals, making it easier to locate people in low-light or obscured areas such as forests, caves, or disaster zones. Thermal camera drones can cover large areas quickly and efficiently, allowing rescue teams to prioritize their efforts and potentially save lives.
Public Safety and Security
Public security sectors have taken advantage of thermal cameras embedded in drones to identify fugitives in difficult-to-reach environments and to help people in risky situations. In addition, these security drones are powerful tools for the prevention and control of fires of any nature.
If before, large search groups had to risk themselves in dense forests and difficult-to-access environments, now, drones coupled with thermal cameras perform a complete scan of a certain area of interest, ensuring the safety of the professionals involved and generating reliable results in real time.
