Method and system for controlling a gimbal
A method for controlling a gimbal includes detecting a motion of the gimbal, determining whether a received control signal indicates that the motion of the gimbal corresponds to a user-intended motion, controlling the gimbal to move along a moving direction of the motion in response to determining that the received control signal indicates the motion of the gimbal corresponds to the user-intended motion, and controlling the gimbal to move along an opposite direction to the moving direction of the motion in response to determining that the received control signal does not indicate the motion of the gimbal corresponds to the user-intended motion.
