Implementation method and control system of headless mode of unmanned aerial vehicle

Abstract

The invention relates to the technical field of unmanned aerial vehicles and discloses an implementation method and a control system of a headless mode of an unmanned aerial vehicle. The implementation method comprises the following steps: an handheld remote control terminal acquires direction information of the handheld remote control terminal; the handheld remote control terminal acquires direction indication information according to operation instructions and the direction of a user when a flying instruction is sent to the unmanned aerial vehicle, and carries the direction indication information in the flying instruction; and the unmanned aerial vehicle calculates flying reference front side of the unmanned aerial vehicle according to the direction information acquired by the unmanned aerial vehicle and the direction indication information carried in the flying instruction after the flying instruction is received by the unmanned aerial vehicle and executes the flying instruction. According to the method and the system, the headless mode of the unmanned aerial vehicle can be relatively simply realized, and the reference front side of a vehicle body in the headless mode can relatively simply correspond to the front side of a remote controller, so that the limit of GPS in the headless mode of the unmanned aerial vehicle is cast off, the influence of the position of the user is avoided, and the user experience of the utilization of the headless mode is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle headless mode technology. Background technique [0002] There are two types of headless modes for existing drones. The first one is to calculate the orientation information of both the drone and the remote control based on the GPS position information, and use the remote control as the starting point to the aircraft as the end point. As the front of the drone. Therefore, the user does not need to care about the direction of the nose of the drone body itself, but only needs to use the orientation between the remote control and the drone as a reference direction, so as to achieve the purpose of simpler control; The magnetic sensor on the aircraft takes the orientation of the nose when it takes off or the orientation of the nose at a certain moment when the headless mode is triggered, as the reference front of the headless mode.

Problems solved by technology

[0003] However, these two methods have the following problems: In the first method, since the GPS position information of both the remote control and the UAV is needed to accurately calculate the reference direction of the UAV in headless mode, as long as there is The GPS information of one party is interfered or the positioning is inaccurate, and the headless mode is likely to cause inaccurate or invalid directions

In the second method, the user needs to always remember to refer to the front during the flight. When the user turns the direction by himself, it is not easy to correspond the user's intuitive "front" with the "front" of the drone, which is likely to cause confusion. poor user experience
