Thermal Drones: The Ultimate Guide for 2023

What are Thermal Drones and How Do They Work?

Thermal drones are drones that are equipped with thermal cameras or payloads that can capture infrared radiation and produce thermal images. Thermal images are different from regular images because they show the temperature of objects rather than their visible light. This allows thermal drones to see things that are invisible to the human eye, such as heat sources, temperature differences, and hidden objects.

Thermal imaging is not the same as night vision, which amplifies the available light to create a brighter image. Night vision still relies on some visible light to work, while thermal imaging can work in complete darkness. Night vision also cannot detect heat sources or temperature differences, while thermal imaging can.

There are different types of thermal cameras and payloads that are available for drones, depending on their features and functions. Some of the most common types are:

• Radiometric: These cameras can measure the exact temperature of each pixel in the image and provide accurate data for analysis.
• Non-radiometric: These cameras can only show relative temperature differences between objects and do not provide exact data.
• Dual-sensor: These cameras combine a thermal sensor with a visible light sensor to create a fused image that shows both heat and details.
• Multispectral: These cameras can capture images in multiple wavelengths of light, such as infrared, visible, and near-infrared, to provide more information about the objects.

To choose the best thermal drone for your needs, you need to consider several factors, such as:

• Resolution: This is the number of pixels in the image and determines how clear and detailed the image is. Higher resolution means better image quality, but also higher cost and lower frame rate.
• Frame rate: This is the number of images per second that the camera can capture and display. Higher frame rate means smoother video, but also higher power consumption and lower resolution.
• Zoom: This is the ability of the camera to magnify or reduce the size of the image. Zoom can be either optical or digital. Optical zoom uses lenses to change the focal length of the camera, while digital zoom uses software to crop and enlarge the image. Optical zoom is better than digital zoom because it does not reduce the image quality.
• Field of view: This is the angle of view that the camera can cover and determines how much of the scene you can see. Wider field of view means more coverage, but also more distortion and less detail.
