Unmanned aerial vehicle(UAV)is a kind of unmanned aircraft operated by radio remote control equipment and self-contained program control device,or operated by on-board computer completely or intermittently.The correct workflow of UAV should be like this.
(1)Start interface:quickly realize the task planning,enter the task monitoring interface,realize the rapid and automatic archiving of aerial photography tasks,divide the functions,and realize the specific and stable operation of the software.
(2)Pre flight inspection:in order to ensure the safety of the mission,the flight control software is used for automatic detection before takeoff to ensure that the GPS,compass,pitot and pitch and roll of the aircraft are in good condition,so as to avoid the occurrence of dangerous situations in aerial photography.
(3)Mission planning:the flight mission planning is carried out in three modes:regional aerial illumination,navigation and hybrid.
(4)Flight monitoring:real time grasp of aircraft attitude,orientation,airspeed,position,battery voltage,instant wind speed and direction,mission time and other important states,so as to facilitate operators to judge the feasibility of the task in real time and further ensure the safety of the task.
(5)Image mosaic:after the aerial photography task is completed,the navigation aerial image is used for image mosaic in the study area.
Drones are often better suited for missions that are too”dull,dirty or dangerous”than manned aircraft.UAVs can be divided into military and civil according to their application fields.In military,UAVs are divided into reconnaissance aircraft and target aircraft.In terms of civil use,UAV+industry application is the real rigid demand of UAV.
