The invention relates to an unmanned aerial vehicle charging
system and charging method based on lasers. The charging
system comprises a
laser transmission power supply device and an unmanned aerial vehicle, the
laser transmission power supply device comprises a power supply, a
laser transmitter unit, a first positioning unit, a first
communication unit and a horizontal-
pitch angle adjustment mechanism, and the unmanned aerial vehicle comprises an unmanned aerial vehicle body, a photovoltaic unit, a rechargeable battery, a second positioning unit, a second
communication unit, a photovoltaic unit attitude adjustment unit and a second
control unit; according to the charging
system, the two positioning units collect position information of the laser transmission power supply device and position information of the unmanned aerial vehicle respectively, the photovoltaic unit is adjusted to be perpendicular to incident
laser beams through the photovoltaic unit attitude adjustment unit, the energy transmission efficiency is improved, and the
energy loss is reduced.
