Abstract

The embodiment of the invention provides a predicted path acquisition method and device based on an unmanned aerial vehicle. The predicted path acquisition method based on the unmanned aerial vehicle comprises the following steps: acquiring a historical motion path, a motion attitude and predicted flight duration of the unmanned aerial vehicle; judging whether a storage motion path matched with the historical motion path exists in a preset database or not; when the storage motion path matched with the historical motion path does not exist in the preset database, determining a fitting function according to the motion posture; performing path fitting according to the historical motion path and the fitting function to obtain a fitting path; and intercepting the fitting path according to the predicted flight duration to obtain a predicted path. Therefore, by implementing the implementation mode, the flight path of the unmanned aerial vehicle can be efficiently predicted in real time, so that the flight universality of the unmanned aerial vehicle is improved.

Description

technical field [0001] The present application relates to the technical field of unmanned aerial vehicles, in particular, to a method and device for acquiring a predicted path based on an unmanned aerial vehicle. Background technique [0002] At present, with the rapid development of drone technology, more and more drones have been put into various working environments. As we all know, drones usually fly according to a preset flight path during flight. It has been found in practice that most of the current flight paths are pre-set by humans, which makes UAV flight lack a certain degree of autonomy, thereby reducing the universality of UAV flight. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a UAV-based method and device for obtaining a predicted path, which can efficiently predict the UAV flight path in real time, thereby improving the universality of UAV flight. [0004] The first aspect of the embodiment of ...
