Unmanned aerial vehicle (UAV) remote sensing, that is, using advanced UAV technology, remote sensing sensor technology, telemetry and remote control technology, communication technology, GPS differential positioning technology and remote sensing application technology, can realize the automatic, intelligent, professional and rapid acquisition of spatial remote sensing information such as land resources, natural environment and earthquake-stricken areas, and complete the application technology of remote sensing data processing, modeling and application analysis. Unmanned aerial vehicle (UAV) remote sensing system has become a hot spot in international research because of its advantages of maneuverability, rapidity and economy, and has gradually moved from research and development to practical application, becoming one of the main aviation remote sensing technologies in the future.
