Abstract: A target object tracking method applied in an aerial vehicle which has a tripod head and a camera connected to the tripod head includes steps of obtaining coordinates of a target object from the target object itself and controlling the aerial vehicle to fly towards such coordinates. Images of the target object are obtained from the camera when the aerial vehicle has reached the target object, and further images are obtained at different time points, to determine a moving direction of the target object. The tripod head is rotated according to the determined moving direction, thereby controlling the camera to keep focusing on and tracking the target object.
