Problems solved by technology

Most of the existing fully autonomously controlled UAVs use GPS for positioning, but the positioning accuracy of GPS is not high enough, and the error can reach several meters. Now some use infrared for auxiliary positioning, and some use icons for auxiliary positioning. Although the positioning accuracy has been improved to a certain extent, the accuracy is still not high enough to accurately align the wireless charging transmitter module with the wireless charging receiving module, thereby reducing the efficiency of wireless charging

Abstract

The invention discloses an unmanned aerial vehicle charging supply positioning method. The method comprises the steps of 1 constructing a wireless charging platform of an unmanned aerial vehicle; 2 setting a beacon for the unmanned aerial vehicle to identify; 3 acquiring image coordinates of the beacon center and guiding the unmanned aerial vehicle to land autonomously; 4 coarse positioning of theunmanned aerial vehicle on the wireless charging platform; 5 accurately positioning the unmanned aerial vehicle on the wireless charging platform; 6 positioning a transmitting coil; and 7 self-checking of the position of the transmitting coil. According to the invention, the unmanned aerial vehicle is guided to land on the top plate of the wireless charging platform in an autonomous landing modeof image navigation and single-light-source assisted positioning; the center coordinates of the unmanned aerial vehicle and a receiving coil are accurately obtained through perspective transformationand laser scanning; a two-axis sliding table is used for controlling a wireless charging transmitting coil to move; high-precision alignment between coils is achieved; coil position self-checking is carried out through charging efficiency maximization; and the charging supply positioning of the unmanned aerial vehicle is high in speed and good in effect.

Description
