Abstract

The invention discloses a method, a device and a system for navigating an unmanned aerial vehicle. The method comprises the following steps of obtaining a target area image collected by a binocular image collecting device which is arranged on the unmanned aerial vehicle; respectively extracting characteristic points of the target area image; detecting and matching the characteristic points, and performing three-dimensional reconstruction on the target area image according to the characteristic points, so as to obtain a three-dimensional model containing three-dimensional coordinate information of a target area; according to a preset flight route and the three-dimensional model, establishing a flight model containing the flight route information, so as to navigate the unmanned aerial vehicle according to the flight model. The method has the advantages that on the basis of the obtained target area image, the flight route of the unmanned aerial vehicle in the target area is determined by an image processing technique, the interference by instable factors is avoided, and the anti-interference property is higher; the stability in the navigation of the unmanned aerial vehicle is favorably improved.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, in particular to a method, device and system for unmanned aerial vehicle navigation. Background technique [0002] With the development and progress of drone technology, plant protection drones have also developed rapidly. [0003] The plant protection UAV has many advantages such as small size, short flight adjustment, high flight efficiency and low operating cost. Compared with traditional manual spraying of pesticides, plant protection drones can easily spray pesticides on taller crops; and compared with manned aircraft pesticide spraying operations, plant protection drones have the characteristics of being able to adapt to small farmlands. [0004] The existing UAV navigation technology is mainly GPS navigation, that is, to use the real-time geographic location information of the UAV to conduct real-time navigation according to the geographic location information. T...
