Problems solved by technology
[0003] At present, UAVs usually contain a magnetometer, which is used to detect the direction of the earth’s magnetic field and to assist the flight control system in judging the UAV’s orientation. out of control
Because the earth's magnetic field is very weak, the magnetometer is easily affected by external magnetic substances. For example, the ferromagnetic substances in the fuselage of the drone and the magnetic field generated by the power line will interfere with the magnetometer
In addition, since UAVs usually carry mounts, and the difference in mount weight will lead to changes in the operating current, which will further lead to changes in the magnetic field strength, so the position and height of the magnetometer are difficult to determine, giving UAVs flight safety belts to hidden danger

The present application proposes a method, device, unmanned aerial vehicle, and storage medium for eliminating magnetic field interference, wherein the above method includes: detecting a first instruction for starting the unmanned aerial vehicle, and responding to the detected first instruction An instruction to measure the mounted weight of the drone to obtain the first mounted weight; calculate the first target height according to the first mounted weight; lift the magnetic force according to the first target height Measure the altitude in the drone, so that the magnetometer extends out of the body of the drone, to eliminate the interference of the magnetic field to the drone. This application converts the weight of the UAV into the height of the magnetometer, thereby controlling the ups and downs of the magnetometer, and using it to eliminate the interference of the surrounding magnetic field on the UAV, which can improve the flight safety of the UAV and the packaging and handling of the UAV. The convenience of transportation.
Description
【Technical field】 [0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to a method, device, unmanned aerial vehicle and storage medium for eliminating magnetic field interference. 【Background technique】 [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. It is widely used in disaster rescue, film and television shooting, power inspection, disaster relief, etc. [0003] At present, UAVs usually contain a magnetometer, which is used to detect the direction of the earth’s magnetic field and to assist the flight control system in judging the UAV’s orientation. out of control. Because the earth's magnetic field is very weak, the magnetometer is easily affected by external magnetic substances. For example, the ferromagnetic substances in ...
