Abstract: A system for controlling a movable object includes a controller in communication with an analyzer and configured to obtain one or more parameters of a target object, obtain signals indicating one or more motion characteristics of the movable object and one or more motion path parameters, determine a motion path for the movable object to travel based on the one or more parameters of the target object and the one or more motion path parameters, and control the movable object to travel along the motion path based on the one or more motion characteristics of the movable object. The motion path is a three-dimensional (3D) motion path defined based on a contour of the target object. A change in a shape, geometry, or orientation of the contour of the target object results in a corresponding change of the 3D motion path.
