Compared to manned aircraft, drones are often better suited for tasks that are too “dull, dirty or dangerous.” UAVs can be divided into military and civilian applications according to the application field. In military terms, drones are divided into reconnaissance planes and drones. Civilian, drone + industry application, is the real need for drones; currently in aerial photography, agriculture, plant protection, micro-self-timer, express delivery, disaster relief, observation of wildlife, surveillance of infectious diseases, mapping, news reports, power patrol The application of inspection, disaster relief, film and television shooting, manufacturing romance, etc. has greatly expanded the use of the drone itself.
