Description

technical field

[0001] The invention belongs to the field of altitude determination control for soft-wing unmanned aerial vehicles, and more particularly relates to a low-altitude flight altitude determination control system for soft-wing unmanned aerial vehicles. Background technique

[0002] At present, drones are used in more and more fields, such as aerial photography, agricultural sowing, emergency communications and material airdrops. However, due to the single function of existing UAVs, many applications are greatly restricted, especially those with strict restrictions on flight height, ground condition perception and location requirements.

[0003] In terms of the means of flight altitude measurement, the current commonly used method mainly uses GPS navigation or barometric altimeter to obtain the distance of the unmanned aerial vehicle by obtaining the absolute altitude and the altitude of the aircraft latitude and longitude position on the map. ground height.
