Description

technical field [0001] The invention relates to the field of aerial scale hyperspectral remote sensing, in particular to an unmanned aerial vehicle system and method for aerial image remote sensing measurement with high spectral resolution, which can be applied to fields such as precision agriculture, mineral exploration, and environmental monitoring. Background technique [0002] At present, in the field of aviation-scale hyperspectral remote sensing, most of the sensor platforms are manned flight platforms, such as hot air balloons, airships, delta-wing aircraft, helicopters, remote sensing aircraft, small and medium-sized fixed-wing aircraft and other small and medium-sized civil aircraft. Due to the manned flight, the risk is great. In addition, it is necessary to hire pilots, apply for airspace and routes, lease aircraft, runways, aprons, airports, etc. Each flight is expensive and has poor mobility. It is impossible to repeatedly test and monitor the same area in a sho...
