Unmanned aerial vehicle laser charging method based on binocular vision positioning

Abstract

The invention relates to an unmanned aerial vehicle laser charging method based on multi-view visual positioning. A visual positioning label and a laser charging panel are installed on an unmanned aerial vehicle; a laser emitter and a plurality of cameras are arranged in the space; the plurality of cameras capture a visual label position signal on the unmanned aerial vehicle and send the signal toa computer system, and the spatial position and attitude information of the unmanned aerial vehicle is obtained through calculation; after a target offset amount and a servo adjustment amount are calculated, the tracking servo module of a laser sighting device is driven to adjust an azimuth angle and a zenith angle, and a laser transmitting end is aimed at the laser charging panel on the unmannedaerial vehicle; and laser is emitted to charge the unmanned aerial vehicle. With the unmanned aerial vehicle laser charging method based on multi-view visual positioning of the invention adopted, theunmanned aerial vehicle can be remotely charged while the unmanned aerial vehicle operates; and the flight time of the unmanned aerial vehicle is prolonged. The method has the advantages of high efficiency, flexibility and the like, and can improve the cruising ability of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to a remote charging technology, in particular to a laser charging method for drones based on binocular vision positioning. Background technique [0002] With the application and development of drone technology, improving the battery life of drones has become one of the key development directions. Solar charging is one of the important means to improve the endurance of drones at present. However, the area of ​​solar panels is limited, the energy power provided by solar energy is small, and it is greatly affected by weather conditions, so it cannot continuously provide energy. Using laser instead of sunlight can overcome the shortcomings of solar charging, which can increase energy power and improve the charging performance of drones. [0003] Visual positioning methods can be divided into relative positioning and global positioning. Relative positioning is to install the camera on a moving UAV and move with the UAV during the po...
