Abstract
A method for controlling a landing gear of an unmanned aerial vehicle (UAV) includes detecting whether a relative-to-ground height of the UAV is greater than a height threshold, where the relative-to-ground height is a vertical height of the UAV with respect to an object; and in response to the relative-to-ground height being not greater than the height threshold and the UAV having not lowered the landing gear, adjusting the relative-to-ground height to the height threshold or above, and lowering the landing gear.
Claims20
A method for controlling a landing gear of an unmanned aerial vehicle (UAV), comprising:
- detecting whether a relative-to-ground height of the UAV is greater than a height threshold, the relative-to-ground height being a vertical height of the UAV with respect to an object;
- and
- in response to the relative-to-ground height being not greater than the height threshold and the UAV having not lowered the landing gear, adjusting the relative-to-ground height to the height threshold or above, and lowering the landing gear.
A user device comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, cause the user device to:
- detect whether a relative-to-ground height of an unmanned aerial vehicle (UAV) is greater than a height threshold, the relative-to-ground height being a vertical height of the UAV with respect to an object, and
- in response to the relative-to-ground height being not greater than the height threshold and the UAV having not lowered a landing gear, adjust the relative-to-ground height to the height threshold or above, and lower the landing gear.
An unmanned aerial vehicle (UAV) comprising:
- a fuselage;
- a landing gear connected to the fuselage;
- a sensing element arranged at the fuselage and configured to sense a relative-to-ground height of the UAV;
- and
- a controller arranged at the fuselage and configured to:
- detect whether the relative-to-ground height of the UAV is greater than a height threshold, the relative-to-ground height being a vertical height of the UAV with respect to an object, and
- in response to the relative-to-ground height being not greater than the height threshold and the UAV having not lowered the landing gear, adjust the relative-to-ground height to the height threshold or above, and lower the landing gear.
