The Solid Waste Landfilling (SWL) holds a high risk of fire emergencies and represents hazards to people and to the environment mainly due to sub-products, odours and volatile and non-volatile compounds from the immense heat caused by decaying solid matter.
Using Drones fitted with new technology Thermal Imaging sensors to detect thermal emissions (looking for fire upfront and localised ignition points), chemical and physical parameters (CO, NOx, O3, CH4, air temperature, relative humidity, etc.). Moreover, the availability of viewpoints at different altitudes allow to enlarge the monitored area with full geometrical resolution using only one camera.
WHAT IS THERMAL IMAGING
Thermal imaging, or thermography, is the detection and measuring of radiation in the infrared spectrum being emitted from an object with the use of thermographic cameras. These infrared imaging systems produce thermal video or still images (thermograms) using colour differences to point out the various temperature points of an object from hot to cold levels. Since the amount of radiation increases with higher temperatures, warm spots will stand out from colder spots on the thermal image. Thermal imaging cameras do not need light to operate, they can detect objects in total darkness or in daylight.
DJI ZANMUSE XT Radiometric 640
Thermal imaging from the air has never been as easy as it is with the DJI Zenmuse XT. By combining DJI’s unrivalled expertise in gimbal technology and image transmission with the industry leading thermal imaging technology of FLIR, the Zenmuse XT is the ultimate solution for rapid and reliable aerial thermal imaging. Capture faster, with pinpoint precision, over large areas, then save them for analysis and reporting.
The camera on the DJI Zenmuse XT radiometric is developed by FLIR. It provides high-sensitivity (50mK) thermal imaging at 640/30 fps. This sensitivity provides accurate temperature measurements ideal for analytics and telemetry. Stabilised and controlled by a custom DJI gimbal, it provides smooth, clear imagery and 360 degrees of seamless rotational movement.
The Zenmuse XT Advanced Radiometry camera used by Drone Media Imaging provides twice the temperature measurement accuracy of the standard Zenmuse XT along with new analysis and recording functions. Simply tap any point in an on-screen image to view the temperature of that point or select an area to measure the average, highest and lowest temperatures as well as their location. The camera can also be calibrated to further increase temperature measurement precision by setting external parameters including background temperature, scene emissivity and more. The temperature of each pixel can be recorded for further processing and analysis.
