Abstract: An aerial vehicle includes a center body, two arm assemblies arranged at the center body, a power device, and a driver mechanism mechanically coupled to the arm assemblies. The power device includes two first and two second rotor power assemblies. Each pair of first and second rotor power assemblies are installed at two ends of an arm assembly. The driver mechanism drives the arm assemblies to move relative to the center body such that distal parts of the two arm assemblies move between first and second height positions. In a direction of a roll axis of the power device, the first rotor power assemblies are closer to an installation site on the center body than the second rotor power assemblies. When the distal parts are at the second height position, spacing between the first rotor power assemblies is larger than spacing between the second rotor power assemblies.

Abstract: A gimbal pose correction method includes obtaining a first pose of a gimbal based on an Inertial Measurement Unit (IMU) arranged at a vertical compensation device configured to be coupled to the gimbal and compensate for movement of the gimbal in a vertical direction, obtaining a second pose of the vertical compensation device based on a vision device arranged at the vertical compensation device, and correcting the first pose according to the second pose.
