Abstract
A method is provided for controlling a gimbal including a mounting member. The method includes determining, through a magnetic sensor, a first deflection angle of the mounting member around a yaw axis in a time period. The method also includes determining, through an inertial measurement unit, a second deflection angle of the mounting member around the yaw axis in the time period. The method also includes determining an angle error of the inertial measurement unit based on the first deflection angle and the second deflection angle. The method further includes controlling attitude of the gimbal based on measurement data of the inertial measurement unit in which the angle error has been corrected.
