Classification: CPC G  B | IPC B  G

Claim 0:
1. A method of tracking a movement of a target by a movable object, the method comprising:
receiving, from a mobile terminal collocating with the target, absolute location coordinate data of the target;
acquiring, by a camera of the movable object, image data of the target;
determining a physical dimension associated with the target, including, in response to a change in a yaw angle of the camera not exceeding a threshold, averaging a current value of the physical dimension and one or more historical values of the physical dimension to determine the physical dimension;
determining, based on the absolute location coordinate data, the physical dimension associated with the target, and the image data of the target, 3D location coordinate data of the target with respect to the movable object; and
controlling, based on the 3D location coordinate data of the target with respect to the movable object, at least one of a direction or a speed of the movement of the movable object, to maintain a constant relative 3D position of the movable object with respect to the target.
