The invention relates to an unmanned aerial vehicle night
plant protection operation method based on multi-view vision, and belongs to the technical field of
aviation systems. The method comprises thefollowing steps of arranging a plurality of
binocular vision sub-platforms around a farmland to be subjected to
plant protection to form a multi-view vision platform; carrying out parameter calibration on the
binocular vision sub-platforms, and then calibrating the position relation between the
binocular vision sub-platforms; calculating the initial position of the
plant protection unmanned aerial vehicle platform relative to the farmland through a multi-view vision
system; planning a flight path of the plant protection unmanned aerial vehicle by using a ground control platform; starting plant protection work, in the operation process, enabling the multi-view vision platform to capture
infrared feature identification points on the plant protection unmanned aerial vehicle platform, calculate the position of the plant protection unmanned aerial vehicle relative to a farmland in real time, and feed back position information to an
autopilot and a ground control platform of the plant protection unmanned aerial vehicle, which is used for correcting the
route of the unmanned aerial vehicle in the plant protection operation process in real time. A
pesticide spraying platform is carried onthe unmanned aerial vehicle platform and is an executing mechanism for plant protection operation of the unmanned aerial vehicle.
