Flight control method of plant protection unmanned aerial vehicle

Abstract

The invention discloses a flight control method of a plant protection unmanned aerial vehicle. The flight control method comprises the following steps: acquiring a plurality of border surveying and mapping points of a target land parcel, and generating a border line of the target land parcel based on the border surveying and mapping points; acquiring preset operation information, and generating aworking path according to the border line of the target land parcel and the preset operation information; and acquiring take-off and landing sites outside the target land parcel and a safe intermediate transit site on the border line of the target land parcel, and generating a safe path of the unmanned aerial vehicle according to the take-off and landing sites and the safe intermediate transit site, wherein barriers do not exist in the safe path. The invention aims at providing the flight control method of the plant protection unmanned aerial vehicle; and the safe intermediate transit site isset in the flight line of the plant protection unmanned aerial vehicle, so that the safe and reliable flight of the unmanned aerial vehicle in the working process is guaranteed.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method for controlling the flight of a plant protection unmanned aerial vehicle. Background technique [0002] At present, with the land transfer and the gradual scale of agricultural land production, in order to improve the efficiency of agricultural production and reduce the cost of agricultural production, there is an increasing demand for drones to spray pesticides and other operations with drones. How to safely and reliably control the flight of UAVs is an important issue in the field of UAVs. The UAV flight control method in the prior art is based on the pre-marked obstacles in the operation area, and performs obstacle avoidance design during path planning to determine the route of the UAV, and control the flight of the UAV based on the determined route. . In this kind of flight control scheme, the flight route is planned based on the marked obstacles i...

AI Technical Summary

Problems solved by technology

In this kind of flight control scheme, the flight route is planned based on the marked obstacles in the operation area; in order to facilitate the operation, the take-off and landing points of the UAV are usually set outside the operation area. During the return process, due to the uncertainty of the return position , fly directly from the return position to the take-off and landing point outside the operation area, if there are obstacles in the flight path outside the operation area, the flight control will be unreliable
