Professional drone pilots use thermal imaging to provide solutions.

How Is Thermal Imaging Formed?

Thermography is a method of measuring the heat emitted from an object or area for analysis. This infrared thermal imaging (IRT) is the process of detecting infrared energy emitted from something and converting the readings into heat.

Most objects emit infrared energy. The higher the temperature, the faster the atoms and molecules move. The faster they move, the more infrared energy is produced.

What Commercial Drones Support Thermal Imaging?

Generally speaking, for most commercial drones to use the drone to operate more applications, it must be able to carry a payload, thermal and infrared cameras can be mounted on the drone to fly over a certain area area to detect heat.

The DJI Zenmuse XT is one of the most advanced drones, and the camera on the DJI Zenmuse XT was developed by FLIR. It offers high-sensitivity (50mK) infrared scanning at 640/30 fps or 336/60 fps, depending on the camera model.

Flir is a global leader in the design and manufacture of thermal imaging infrared cameras. FLIR's aerial thermal imaging technology is very mature, and FLIR thermal imaging infrared cameras are suitable for both drone-mounted sensors and ground-based sensors.

The thermal imager sensor of Autel EVO II Dual 640t is FLIR BOSON Sensor, which can capture 640*512 or 320*256 infrared images. Autel EVO II Dual 640t has dual-sensor cameras, 8k and infrared imaging cameras can record at the same time.

How To Interpret Infrared Or Thermal Images Captured By Industrial Drones?

A thermal imager can help a business or utility get the most out of its investment in thermal technology. Thermal imaging is different from drone camera imaging, which captures visible light and thermal cameras captures infrared energy.

Both visible light and infrared are part of the electromagnetic spectrum, visible light has a wavelength of light in the 0.4-0.75 micron wavelength band, and the infrared energy detected by drone thermal imagers spans the 7.5 to 14 micron band, which is why we need infrared thermal images .

What Is The Relationship Between Heat And Temperature?

Explain that thermal energy and temperature are not the same concept when taking infrared images from drones. When the molecules of an object are in frictional motion, the temperature of the object will rise, and the thermal imager on the drone is the thermal energy from something, not its temperature.

Temperature can be thought of as a result of more or less thermal energy in matter - if we add thermal energy, the temperature goes up; if we remove energy, the temperature goes down. The temperature values ​​we see on infrared images are calculated, not detected.

What Makes Something Look Hot Or Cold?

Most of the time, the infrared energy we see from an object comes from the surface of the object. But this energy doesn't necessarily come from the object itself. It can come from the object, but it can also be reflected by the object, pass through the object, or a combination of the three. In order to properly interpret the image and measure the temperature contained within it, we first have to understand where the energy we see is coming from.

The energy that comes directly from an object is called emitted energy. The reflected energy comes from something else, but is reflected into your camera from the object you're looking at. If the energy behind the object you are looking at passes through the object you are interested in, the material is said to be "transmitting".

Everything a drone thermographer sees in an infrared image is some combination of emitted, reflected and/or transmitted energy. This relationship can be expressed mathematically like this: emission + reflection + transmission = 1 (with one representing 100 percent of the infrared energy being seen).

How To Measure The Radiant Heat Of An Object?

A measure of how efficiently an object radiates heat is called emissivity. Emissivity is the ratio of the energy in an object to the energy it emits, and these ratios are displayed as values ​​between 0 and 1.0. Therefore, an object with 90% emissivity has an emissivity of 0.9.

What Affects The Emissivity Of An Object?

Materials - Emissivity is first and foremost a material property. In general, organic objects - dirt, rocks, wood, animals (including people) are highly radioactive; usually have an emissivity greater than 0.95.
Surface finish - The smoother and brighter an object is, the lower its emissivity and the higher its reflectance.
Viewing Angle - If you look at a high emissivity object from an angle below 90° it becomes more reflective.
Geometry - Due to these changes in geometry, objects with lots of holes and angles in them may appear hotter than they actually are.
