1. Working principle of drone thermal imaging technology
The core of drone thermal imaging technology is the infrared thermal imaging camera, whose working principle is based on the infrared radiation emitted by the object itself. Here are the key principles:
| principle | illustrate |
|---|---|
| infrared radiation | All objects with a temperature above absolute zero (-273.15°C) emit infrared radiation, the intensity of which is proportional to the object's temperature. |
| Thermal imaging camera detection | The thermal imaging camera receives the infrared radiation emitted by the object through an infrared sensor and converts it into an electrical signal. |
| image generation | The electrical signal is processed to generate a thermal image, with different temperature areas displayed in different colors or grayscales. |
| Drone mounted | The thermal imaging camera is installed on the drone and transmits real-time images back to the ground station through wireless transmission to achieve remote monitoring. |
2. Application scenarios of drone thermal imaging technology
Drone thermal imaging technology is widely used in many fields because of its efficiency and flexibility:
| Application areas | Specific use |
