The invention discloses an unmanned aerial vehicle navigation method and an unmanned aerial vehicle navigation device. The unmanned aerial vehicle navigation precision is improved. The unmanned aerial vehicle navigation method includes the comprises the following steps: acquiring the coordinate point of an unmanned aerial vehicle in a current position as a starting point, and photographing the unmanned aerial vehicle at the starting point to obtain a photograph, wherein the photograph comprises a target image; carrying out edge characteristic information extraction on the photograph to obtain the contour coordinate point set of the target image; determining the coordinates of a target point according to the coordinates of all coordinate points included in the coordinate point set; determining the GPS coordinates of the target point according to the coordinates and the GPS coordinates of the starting point and the coordinates of the target point; and determining the flight direction of the unmanned aerial vehicle flying to the target point according to the GPS coordinates of the starting point and the GPS coordinates of the target point.
Description
technical field [0001] The invention relates to the technical field of navigation, in particular to a navigation method and device for an unmanned aerial vehicle. Background technique [0002] Navigation technology is one of the most critical and important technologies of UAVs. UAV navigation is to correctly guide UAVs to their destinations along a predetermined route within a specified time according to the required accuracy. [0003] Most of the existing geographic information-assisted navigation technologies need external geographic information databases, external data interfaces provided by relevant manufacturers, or global GPS (Global Positioning System, Global Positioning System) geographic information assistance. In the local environment of automated operations, such as local obvious landmarks and environments, large-scale geographic information databases sometimes cannot provide effective information, and can only rely on human control to carry out operations, such a...
