Abstract

The invention discloses an unmanned aerial vehicle positioning switching method, an unmanned aerial vehicle positioning switching device and an unmanned aerial vehicle and belongs to the unmanned aerial vehicle field. The method includes the following steps that: the current height of an unmanned aerial vehicle is detected; and if the current height of the unmanned aerial vehicle is larger than a first threshold value and is smaller than a second threshold value, weighting processing is performed on first position information provided by a GPS and second position information provided by an assistant positioning system, so that the weighed information is adopted as the position information of the unmanned aerial vehicle, wherein the first threshold value is smaller than the second threshold value. According to the unmanned aerial vehicle positioning switching method, the unmanned aerial vehicle positioning switching device and the unmanned aerial vehicle of the invention, data fusion is performed on GPS positioning and assistant positioning, so that the smooth transition of positioning data used by the unmanned aerial vehicle before and after positioning mode switching can be facilitated, and therefore, positioning accuracy can be ensured, large jitter of the positioning data can be avoided, and the flight safety of the unmanned aerial vehicle can be ensured.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a positioning switching method and device for an unmanned aerial vehicle and an unmanned aerial vehicle. Background technique [0002] Traditional UAV positioning is usually implemented by GPS (Global Positioning System, Global Positioning System) positioning. However, in places relatively close to the ground (such as drone takeoff and landing points), GPS signals are easily blocked by surrounding objects, resulting in inaccurate positioning. Even if the differential GPS technology with high precision is used, this problem cannot be avoided. Therefore, only relying on GPS positioning cannot meet the positioning requirements of UAVs. [0003] With the development of indoor wireless positioning technology, its accuracy can reach centimeter level. Therefore, high-precision positioning services can be provided when the drone is near the take-off and landing point. [0004] ...
