Abstract

The invention discloses a method and system for correcting the take-off and landing course of an unmanned aerial vehicle, and relates to the technical field of take-off and landing of an unmanned aerial vehicle, including a method for correcting a take-off course and a method for correcting a landing course. The method for correcting the take-off course comprises the following steps: Step 1: Open the top cover of the machine nest and obtain the initial direction north east α1 angle of the rotating platform and the wind direction information north east β angle, step 2: The rotating platform calculates the take-off heading correction angle of the UAV according to the difference θ=β‑α1; step 3: When the rotating platform rotates to the difference |θ|=β‑α1<1°, send the take-off command to the drone through the nest; Step 4: After the drone receives the take-off command, follow the standard take-off process, The take-off process is completed; the course correction strategy of the method of the present invention is implemented in the control structure of the machine nest, which can make the course of the unmanned aerial vehicle in the windward position when the unmanned aerial vehicle is ready to take off, and maximize the use of the resistance of the unmanned aerial vehicle during take-off. wind performance.

Description

technical field [0001] The invention relates to the technical field of take-off and landing of unmanned aerial vehicles, in particular to a method and system for correcting the take-off and landing of unmanned aerial vehicles. Background technique [0002] With the development of drone technology, the application scenarios of drones are becoming more and more extensive, such as in power line patrol, traffic rescue and customs border defense. It needs to be charged or replaced to ensure its continuous flight. The UAV automatic airport system is a full-process automation facility that can realize the automatic take-off, automatic inspection, automatic return to the nest, automatic charging and replacement, and intelligent storage of UAVs. It can replace manual control by remote control or ground station. UAVs perform aerial inspection operations to improve the automation level of UAVs performing tasks. At present, there are multi-rotor UAV automatic airports and vertical tak...
