Advantage of UAVs

2020-10-28

Compared with manned aircraft, UAVs have low cost, no risk of casualties, good maneuverability, low visibility, low cloud cover, low-altitude flight, good safety, wide application scenarios, and can significantly increase the daily flying time and speed up Operational progress, therefore, UAV has been developed rapidly in recent years. The drone can be equipped with a visible light camera and an infrared thermal imager for aerial photography. Thermal imaging cameras can image the temperature distribution of the scene by detecting the infrared rays emitted by the object itself, providing more information than visible light cameras. It can be used for night vision tracking, search and rescue, equipment inspection, agriculture, forestry, animal husbandry and fishery. For example, the forestry department uses drone-borne thermal imaging cameras to conduct forest fire prevention and find high-temperature flammable points in time. In the agricultural field, aerial photography using thermal imaging cameras can detect the temperature of the ground and crops and understand the irrigation conditions. Because the temperature of industrial sewage is higher than that of river water, the environmental protection department uses drones equipped with thermal imaging cameras to visually detect sewage discharge during the day and night.
