  • Publication number: 20190258255
    Abstract: A control device includes a control circuitry configured to estimate a first position for a movable object to reach by a time point in association with movement of an object, derive a first speed that the movable object needs to reach the first position by the time point, and determine if the first speed is greater than a second speed, beyond which the movable object is not able to track the object. If so, the control circuitry determines a second position that the movable object is able to reach by the time point by moving toward the first position at the second speed, and defines at least one of an imaging condition or an imaging direction of an imaging system carried by the movable object based on a relative position between the movable object at the second position and the object at the time point.
