Thermal Sensors

Aerial thermal imaging for analysis and reporting

Thermal sensors measure the relative surface temperature of land and objects beyond the scope of human vision.

A microbolometer is a specific type of resistor used as a detector in a thermal camera. When long wave infrared radiation emitted from objects strikes the microbolometer, it heats up and this changes its electrical resistance. These changes are converted to electrical signals and processed into an image.

Drone-based thermal imagery has many applications including surveillance and security, water temperature detection and water source identification, livestock detection and heat signature detection.

Data Collection Using Thermal Sensors

When it comes to capturing quality aerial thermal images, flight planning is important. Before you take flight, allow a thermal sensor to warm up for 5 minutes. If you have breaks between flights lasting longer than an hour, perform the warm up again before returning to the air. To avoid thermal blur, keep a low flight speed (about 4 meters per second).

Also, pay attention to climate, and fly on days with optimal weather conditions. Both wind (over 15 mph) and precipitation can change surface temperatures. Flying in high humidity (over 60 percent) will result in a haze in your source imagery.
