Patent Images

1. A method for stabilizing an image of an object being taken from a video camera, the video camera being moved by a transport mechanism and being controlled by a line-of-sight controller, the method comprising:

  • receiving a plurality of images of the object; and

    for each of the plurality of received images, receiving a velocity and orientation of the transport mechanism;

    receiving an orientation of the camera relative to the transport mechanism;

    receiving a scan and tilt rate of the camera;

    receiving a distance from the camera to the object;

    calculating an inter-frame stabilization adjustment based on the velocity and orientation of the transport mechanism, the orientation of the camera, the scan and tilt rate of the camera, and distance to the object;

    calculating a line-of-sight adjustment for the line-of-sight controller based on the inter-frame stabilization; and

    controlling the line-of-sight controller in accordance with the calculated line-of-sight adjustment.
