Accurate unmanned aerial vehicle positioning method and device

Abstract

The invention relates to the technical field of positioning, and discloses an accurate unmanned aerial vehicle positioning method and device. The accurate unmanned aerial vehicle positioning method provided by the invention comprises the steps that the target position information is acquired, wherein the target position information comprises the target position and the first signal receiving intensity of N wireless hotspots at the target position, and N is a natural number greater than 2; the second signal receiving intensity of N wireless hotspots is acquired when a first position D1 is reached; and according to the first signal receiving intensity and the second signal receiving intensity, the unmanned aerial vehicle is controlled to reach the target position from the first position D1. The embodiment of the invention further provides an accurate unmanned aerial vehicle positioning device. According to the embodiment of the invention, through the assistance of the wireless hotspots at the target position, the unmanned aerial vehicle positioning accuracy is improved; unmanned aerial vehicle direct delivery is realized without increasing extra cost; and the scope of unmanned aerial vehicle transport operations is expanded.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a method and device for precise positioning of an unmanned aerial vehicle. Background technique [0002] With the rapid development of UAV technology and the reduction of cost, the application of UAV has developed from the traditional military field to the civilian field. For example, with the rapid development of e-commerce, people began to use drones to undertake express delivery. [0003] In the process of realizing the present invention, the inventor found that the existing unmanned aerial vehicles still have the following deficiencies: the existing unmanned aerial vehicles usually use GPS (Global Positioning System, Global Positioning System, referred to as GPS) to locate the latitude and longitude, and use air pressure sensors to locate Altitude, because there is a certain error in this positioning method itself, and if it is affected by occlusion or bad weather, the e...

[0003] In the process of realizing the present invention, the inventor found that the existing unmanned aerial vehicles still have the following deficiencies: the existing unmanned aerial vehicles usually use GPS (Global Positioning System, Global Positioning System, referred to as GPS) to locate the latitude and longitude, and use air pressure sensors to locate Altitude, because there is a certain error in this positioning method itself, and if it is affected by occlusion or bad weather, the error may be even greater. As a result, the current drones generally need to send items to Go to the designated location (the area near the target user's location), and then deliver it to the user by the courier

However, since this method needs to place an additional auxiliary positioning device at the destination, it will also increase costs unnecessarily, which is not conducive to the popularization of drone transportation business
