Abstract

The invention discloses a flight control method, and the method is used for an unmanned plane. The method comprises the steps: obtaining the data information detected by a plurality of sensors (14) disposed on the unmanned plane; carrying out the fusion of the data information, so as to enable the data information to be unified in time; and calculating the relative height of the unmanned plane to a ground object according to the data information after fusion. The invention also relates to the unmanned plane and the flight control system.

Description

technical field [0001] The invention relates to the technical field of safe flight control of micro-UAVs in the low-altitude field, in particular to an unmanned aerial vehicle, a flight control method and a flight control system thereof. Background technique [0002] In recent years, with the rapid development of UAV technology, UAV technology has been applied in various fields. Among them, it has played an important role in the field of agricultural aviation. A typical case is to spray pesticides on agricultural plants. Existing agricultural aircraft mainly rely on manual visual inspection for pesticide spraying operations. This method will lead to uneven spraying of pesticides and reduce the practicability of agricultural aircraft in the case of uneven farmland terrain. [0003] In the prior art, UAVs can realize the functions of obstacle avoidance and height measurement. However, the vision and ultrasonic technologies used in UAV obstacle avoidance and height measuremen...
