Abstract

The embodiment of the present invention relates to a method and device for correcting the ground altitude, and an unmanned aerial vehicle. The method is applied to the unmanned aerial vehicle, and the unmanned aerial vehicle includes a ground sensor for detecting the ground altitude between the unmanned aerial vehicle and the landing point. The method includes: obtaining the normal height-to-ground height before the abnormality of the ground-to-ground sensor; calculating the correction amount of the ground-to-ground sensor during the abnormality; . The method obtains the normal altitude of the ground sensor of the unmanned aerial vehicle before the abnormality occurs, and then corrects the normal altitude according to the correction value of the ground altitude calculated by the ground sensor during the abnormal period, thereby improving the ground altitude of the unmanned aerial vehicle. The accuracy of the altitude over the ground improves the landing performance of the aircraft.

Description

【Technical field】 [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method and device for correcting ground altitude, and an unmanned aerial vehicle. 【Background technique】 [0002] When the aircraft is flying normally in the air, its ascent and descent speeds are generally faster. For commercial unmanned aerial vehicles, in order to achieve a better customer experience and from the perspective of safety, the aircraft will be limited at low altitudes. , especially the speed during take-off and landing will be limited to a small size, so as to facilitate safe and smooth take-off and landing. [0003] In the process of realizing the present invention, the inventors found that the relevant technology has at least the following problems: when the aircraft takes off and lands, the altitude over the ground is a key information, if the altitude over the ground is inaccurate, it will affect the take-off and landing performance of the...
