Abstract

The invention discloses an autonomous path planning method for a plant protection unmanned aerial vehicle. A spraying area of the unmanned aerial vehicle is given. After the unmanned aerial vehicle receives a spraying task, a to-be-sprayed area is divided into strip-shaped areas, a spraying path is planned, the unmanned aerial vehicle tracks the spraying path to carry out a spraying mission, complex earlier-stage preparatory work is not required before the unmanned aerial vehicle works, spraying work is performed according to the pre-planned path, overspray and missing spray and the like are avoided, pesticides are saved, the pest control effect is improved, and manpower is saved.

Description

technical field [0001] The invention relates to the field of aircraft control, in particular to an autonomous path planning method for a plant protection drone. Background technique [0002] With the advancement of communication electronics technology and control technology, UAVs are applied to more and more fields, among which the application of UAVs in the field of agriculture has received widespread attention. UAVs are different from traditional pesticide spraying pest control The method has huge advantages, it liberates manpower, improves the operation speed, the spraying of pesticides is more penetrating, improves the control effect, reduces the use of pesticides, reduces environmental pollution, and avoids direct contact between people and pesticides Thereby ensuring people's safety and health. [0003] The existing method of drone spraying is mostly manually controlled by skilled pilots, but this method has a limited range of action. When the drone is far away from t...
