Thermal Drone Technology

How Thermal Drones Work

A thermal drone does more than just take pictures from the sky. It uses thermal imaging to find heat that people cannot see. Here is how it works:

The drone has a special thermal camera and a normal camera.
The thermal camera senses infrared radiation from things, based on their temperature.
The drone’s software changes this heat into bright colors. Hot spots look red or yellow. Cooler places show up as blue or purple.
You can spot leaks, hot parts, or hidden issues. This works even when it is dark, foggy, or smoky.

Thermal imaging drones use GPS to fly the right path and mark locations. Obstacle avoidance helps the drone stay safe. Many drones can fly for a long time and handle bad weather. Some can even fly by themselves and repeat the same path for steady results.

Tip: High-resolution thermal imaging and advanced cameras help you see small temperature changes. This lets you find problems early, before they get worse.

Thermal imaging technology also uses AI to look at data, check old inspections, and make reports. This makes your work faster and easier.
