Method for detecting landing of unmanned aerial vehicle, electronic device and unmanned aerial vehicle

An electronic device, comprising:

• at least one processor;
• and
• a memory communicatively connected with the at least one processor;
• wherein
• the memory stores instructions executable by the at least one processor, and the instructions, when executed by the at least one processor, cause the at least one processor to execute a plurality of operations, wherein the unmanned aerial vehicle comprises a plurality of supporting vertical rods with an adjustable length, and the plurality of operations comprise:
• acquiring a current ground clearance of each of the plurality of supporting vertical rods;
• acquiring a current height above ground of the unmanned aerial vehicle in response to determining that a landing instruction is received;
• determining whether a fuselage of the unmanned aerial vehicle is horizontal in response to determining that the current height above ground reaches a preset height node;
• in response to determining that the fuselage of the unmanned aerial vehicle is horizontal, adjusting a length of the supporting vertical rod according to the current ground clearance of the supporting vertical rod to keep the fuselage horizontal when the unmanned aerial vehicle lands;
• and
• controlling the unmanned aerial vehicle to descend for landing.

An unmanned aerial vehicle, comprising:

• a fuselage;
• a plurality of supporting vertical rods with an adjustable length;
• a plurality of supporting bars being installed outside the fuselage, the other ends of the plurality of supporting bars being respectively connected with a supporting vertical rod, and the supporting vertical rod being a controllable telescopic rod;
• a plurality of ranging units, the plurality of ranging units being respectively installed below the plurality of supporting bars, and the ranging unit being configured to detect a distance between the corresponding supporting vertical rod and a detection target;
• a motor, the motor being configured to control the supporting vertical rod to extend or contract;
• a flight control system, the flight control system being configured to execute a method for detecting landing of an unmanned aerial vehicle;
• and
• a power supply, the power supply being configured to be accommodated in the fuselage and to provide power for the motor, the ranging unit and the flight control system;
• wherein the flight control system is configured to:
• acquire a current ground clearance of each of the plurality of supporting vertical rods;
• acquire a current height above ground of the unmanned aerial vehicle in response to determining that a landing instruction is received;
• determine whether a fuselage of the unmanned aerial vehicle is horizontal in response to determining that the current height above ground reaches a preset height node;
• in response to determining that the fuselage of the unmanned aerial vehicle is horizontal, adjust a length of the supporting vertical rod according to the current ground clearance of the supporting vertical rod to keep the fuselage horizontal when the unmanned aerial vehicle lands;
• and
• control the unmanned aerial vehicle to descend for landing.
