Abstract

The invention discloses an unmanned aerial vehicle take-off and landing course correction method and system, relates to the technical field of unmanned aerial vehicle take-off and landing, and comprises a take-off course correction method and a landing course correction method. The take-off course correction method comprises the following steps: step 1, opening a nest top cover and obtaining an initial direction north-to-east alpha 1 angle and a wind direction information north-to-east beta angle of a rotating platform, and step 2, calculating a take-off course correction angle of the unmanned aerial vehicle by the rotating platform according to a difference value theta = beta-alpha 1; 3, rotating the rotating platform until the difference value theta is equal to beta-alpha1lt; at 1 degree, sending a take-off instruction to the unmanned aerial vehicle through the nest; 4, after the unmanned aerial vehicle receives the takeoff instruction, the takeoff process is completed according to the standard takeoff process; the course correction strategy of the method is implemented in a nest control structure, the course of the unmanned aerial vehicle can be in a windward position in the stage that the unmanned aerial vehicle prepares to take off, and the wind resistance of the unmanned aerial vehicle is utilized to the maximum extent during take-off.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle takeoff and landing, and in particular to a method and system for correcting the course of unmanned aerial vehicle takeoff and landing. Background technique [0002] With the development of drone technology, the application scenarios of drones are becoming more and more extensive, such as power line inspection, traffic rescue, and customs and border defense. In the above application scenarios, after a period of work, the drone 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 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 conduct aerial inspection operations and improve the automation level of UAVs in performing t...
