    摘要： A method of recognizing a self location of an image acquisition device by acquiring an image of two or more reference objects is provided. The method of the present invention comprises setting an actual camera plane, two or more reference object planes, and two or more virtual viewable planes located between the actual camera plane and the reference object planes; projecting the reference objects to a corresponding one of the virtual viewable planes; calculating a distance between a viewing axis and the reference objects and a distance between the viewing axis and images on the actual camera plane, the images corresponding to the reference objects; and sensing the self location of the image acquisition device by using an orientation and a zoom factor of the image acquisition device and coordinates of the reference objects, wherein the zoom factor is a ratio of a length of the reference object plane and a distance between the reference object plane and the virtual viewable plane, and the actual camera plane, the virtual viewable plane, and the reference object plane are perpendicular to the viewing axis.

    摘要： An apparatus for actively tracking an object is provided. The apparatus includes a camera unit; a motor drive for changing a shooting direction of the camera unit; and a controller for acquiring a first comparative image and a second comparative image in sequence using the camera unit, comparing the first comparative image with the second comparative image, detecting a moving direction and a speed of an identical object existing in the first and second comparative images, determining an estimated location of the object after receipt of the second comparative image based on the detected moving direction and speed, and enlarging and capturing the object in the estimated location of the object.
