Problems solved by technology

[0003] In the process of realizing the present invention, the inventors found that the prior art has the following problems: At present, when the unmanned aerial vehicle lands at the take-off point, it mainly relies on GPS positioning or position estimation to realize the landing of the unmanned aerial vehicle. The error and the error of position estimation increase over time, so the UAV cannot achieve accurate landing when flying for a long time or in a place with poor GPS signal

Abstract

The invention discloses a UAV (unmanned aerial vehicle) landing method and system. The method comprises steps as follows: the flight height of a UAV is acquired; a template image corresponding to the flight height is acquired according to the flight height of the UAV; a scene picture is shot by a camera device of the UAV, and the shot picture is acquired; the shot picture is matched with the template image corresponding to the flight height, and the position where the UAV deviates from the target landing site is obtained; the UAV is controlled to fly to the target landing site on the basis of the position where the UAV deviates from the target landing site and controlled to land at the target landing site. By means of the UAV landing method and system, the UAV accurately lands without GPS positioning or position estimation.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a landing method and system of an unmanned aerial vehicle. Background technique [0002] Because UAVs have the advantages of good maneuverability, low cost, and easy use, UAVs have been used in many industries, such as aerial photography, agricultural plant protection, surveying and mapping and other fields. [0003] In the process of realizing the present invention, the inventor found that the prior art has the following problems: when the current unmanned aerial vehicle lands at the take-off point, it mainly relies on GPS positioning or position estimation to realize the landing of the unmanned aerial vehicle, but because the GPS has a meter level And the error of the position estimation accumulates with time, so the drone cannot achieve accurate landing when flying for a long time or in a place with poor GPS signal. SUMMARY OF THE INVENTION [0004] The mai...
