Abstract

A control method for an unmanned aerial vehicle (UAV) is provided. The method includes: obtaining, from a depth-sensing camera, images of a surface below the unmanned aerial vehicle; obtaining, from a gyroscope, current pitch angle of the unmanned aerial vehicle; determining, at the unmanned aerial vehicle, a current altitude of the unmanned aerial vehicle based on the images and the current pitch angle; determining, at the unmanned aerial vehicle, whether the current altitude of the unmanned aerial vehicle is less than a predefined value; and controlling, at the unmanned aerial vehicle, a drive unit to rotate so as to cause the unmanned aerial vehicle to slow down in a balanced condition if the current altitude of the unmanned aerial vehicle is less than a predefined value.
