What are thermal imaging cameras?

Thermal imaging sensors are also referred to as thermal cameras, infrared cameras, thermal imaging cameras, temperature cameras, etc. Thermal imaging cameras work on the principle of infrared imaging. It emits infrared radiations that are sensitive to heat. 

The thermal imaging sensor detects the heat bodies and produces a precise image of the objects in the surrounding. The thermal images are more clear and detailed than the normal ones.

How does thermal imaging cameras operate with drones?

When the drones are equipped with a special infrared camera, it can convert the heat energy into visible light, which our eyes can analyze that particular scene or object. 

The drone thermography cameras are commonly used by firefighters and the members of the public safety department to find out the persons who are missing. Let me give an example for this with a real incident. A 38-year old man found missing in Waterloo, Canada. The law enforcement officers in Waterloo used airborne system with a thermal imaging camera to find him.

Agricultural workers also use these drone thermal cameras to identify highly efficient cultivation and harvesting methods. These are just a few uses of drone thermography cameras.

What can Thermal Cameras Capture?

Thermal energy or heat is emanated from every source on our planet and in our universe. Thermal imaging cameras can capture images of heat emissive objects. They might be;

  • Living things – Human, flora and fauna
  • Buildings – Skyscrapers, factories, houses, tents, and large storeyed buildings.
  • Machinery – Conveyor belts, engines, and assembly lines.
  • Vehicles – All types of automobiles, planes, and boats.
  • Electrical – Electric circuits, power lines, coupling capacitor and insulator.
  • Liquids and Gases – All those that emit thermal radiations. 

Uses of Thermal Cameras

Here are some of the best applications of thermal imaging drone cameras in UAVs. Drones with on-board thermal cameras save your money and time. It is a very safe method to inspect dangerous equipment.

Utility Inspections

Drones with thermal thermal vision cameras allow companies to gather quickly the measured radiometric temperature data and easily cover large substations. With the help of a portable imager it takes the transmission and distribution lines within a fraction of the time.

Utility inspections include power lines, water works, telecoms masts, chimney stacks, and much more.

Firefighting

It is a great boon specially for firefighting. Fire departments have been using portable thermal imaging cameras before the existence of drones. Now drones with thermal cameras play a major role. Drones with thermal vision cameras provide the live stream of structural fires, forest fires, and wildfires from above.

So the commanders are able to see the happenings through the smoke and monitor their personnel in large fire scenes. It provides valuable information about the fire rate and flow paths.

Solar Farm Surveys

UAS thermal imagery of a solar panel array in Switzerland (Source: Wikipedia)

Drones with thermal cameras have the ability to scan large solar panel installations within a few minutes. This allows the operator to measure potential problem areas with a single aerial view. It is impossible to inspect the solar farm from the ground.

Roof Inspections

Before the invention of drones, building and roof inspections was very difficult and took a long time. This was the major reason for workplace accidents for many years. But now, drones with thermal cameras take just a few minutes for building and roof inspections. This saves time and life of the inspectors by visually identifying the problems. This is the great advantage for inspectors in delivering accurate data.

Drone thermal cameras inspect on the exterior of the building.  Similar to drone thermal cameras, there are also thermal imaging cameras for moisture detection and termite detection. These cameras helps to detect any damages or termites present on the interior of the wall of the building. 

Search and Rescue

A drone with a thermal camera is a necessary equipment for rescuers. The thermal camera can be used during both day and night rescue missions. Drones can see and cover over hundreds of acres in minutes.

During the day, the heat radiation from a missing person on a mountain is much higher than that of a normal standard video camera. It is difficult for a standard video camera to locate the missing person, if they are wearing the same color clothing as the surroundings. But drones with thermal cameras can provide you accurate information.

To prove this, here is a real incident for you that happened on October 15, 2019. 

 A 6-year old boy Ethan Haus went missing for more than 10 hours in the woods. More than 700 volunteers came out and searched for the boy, but no one could find him. Finally, a thermal drone operator Steve Fines found him at about 1:30 am using his drone fitted with a FLIR Zenmuse XT2 Thermal Imaging Camera. 

Mining

In case of coal mining, coal is often stored in large storage containers in large quantities. This may lead to the risk of fire. It is very important to carry out temperature monitoring of these coal containers, because self-ignition can easily take place.

A drone with a thermal camera is the fastest way to inspect or analyze the health of the equipment especially in large conveyor belts.  If the equipment is stressed, then the thermal camera will show it hotter. It also identifies the break in the equipment.

Things to look for in Best Drone Thermal Cameras

Before purchasing a thermal camera for the drone, remember some questions while choosing the right thermal imaging camera to get the job done.

  • What is the lens of a thermal vision camera?
  • What is the clarity of the image?
  • What is the size of the camera?
  • How can it bear the harsh climatic scenarios?

Resolution (640 vs 336)

Thermal drone cameras come with a variety of resolution options namely 640×512 pixels, 336×256 pixels, etc. Both types of resolution provide clear images with a wide field of view. 

336×256 pixel resolution is good enough for basic inspection, but for public safety and rescue operation, I suggest a thermal drone with a 640×512 pixel resolution that provides a larger field of view.  

Refresh Rate

The refresh rate is defined as the frequency at which the image is refreshed and displayed on the screen. For example, a 30Hz refresh rate in a drone thermal camera means the image is refreshed 30 times per second. 

The higher the refresh rate, the highest is the image clarity with no blurring. Lower refresh rates can cause image distortion. Usually, rescue teams record the entire scene to get a better chance of finding people who are missed. 

Color Palette

Color palettes are responsible for producing bright, vivid images of your target. Most of the thermal cameras are provided with multiple color options. Among them, White hot and black hot are very popular and are used for various purposes especially, for search and rescue operations. The object in the scene that gives off more radiation will be displayed white and the least radiant object will be black or vice versa. The remaining in the scene will be displayed as a different shade of gray. 

Recommended boards for search and retrieval are white hot and black hot because the objects with the largest temperature difference are highlighted and shown on the display screen. These color palettes perform even better when there is a high contrast between objects.

Lens

Thermal cameras for drones come with various lens options. These lenses are fixed and cannot be interchanged. Make sure whether the lenses are made of germanium. This allows IR radiation easily to pass through and so you’ll be able to get bright, crystal clear images.

Easy to use

Nowadays the thermal cameras are developed with advanced technologies that are extremely easy to operate. The images are bright, vivid, and crystal clear to understand the scenario. But a little training is required for beginners to operate.

Resistance

Thermal imaging cameras can capture images even in total darkness. Although it performs well in the dark, make sure whether the camera is not affected by climatic changes like the fog, rain, and snow. 

Also, before getting, ensure whether the thermal camera can withstand certain harmful elements like the dust and smoky environments.

Final Words

There is never a better or easier way for inspections other than drone thermal cameras. It is an easy-to-use thermal solution, which can save a great deal of time and money, as well as ensuring that your workplace is safe from the hidden dangers that are invisible to the human eye.
