What are the characteristics of drone aerial photography?

The characteristics of UAV aerial photography are analyzed in detail: in aerial photography, remote sensing aerial photography has broad market prospects, and its main advantages are: many aerial photography work sites are airspace, high altitude or dangerous areas that cannot be reached by manned aircraft; The air flight cost of unmanned aerial vehicles is only a fraction of that of manned aircraft. Small size, flexible action, can fly at low altitude, some operations are impossible to increase the cost of manned aircraft. The approval procedure for UAV air flight is simple. For example, the use of the largest remote-controlled airship for aerial photography over the city requires approval from the meteorological department according to regulations. Because it is a remote-controlled aircraft, it basically does not need approval (except airports and special areas). Other aircraft, such as remote-controlled helicopters, do not need approval because of their small size. The drone is flexible and flexible, and it is handy to choose perfect angle; Low requirements for landing sites; The aerial image of UAV has the advantages of high definition, large scale, small area and high realism. In order to ensure the timeliness of data, traditional high-resolution satellite remote sensing data generally face two problems. First, the timeliness of archived data is poor; The second is that programming shooting can get the latest images, but it usually takes a long time and has relatively low timeliness. UAV aerial photography can solve this problem well, and the working group can start at any time and shoot at any time.

UAV aerial photography has a wide range of applications: UAV aerial photography technology can be widely used in national ecological environment protection, mineral resources exploration, marine environment monitoring, land use survey, water resources development, crop growth monitoring and yield estimation, agricultural operations, natural disaster monitoring and evaluation, urban planning and municipal management, forest pest protection and monitoring, public safety, national defense, digital earth, advertising photography and other fields.
