Abstract
A method and system for far field image navigation sensing are described. The method includes pre-processing an image from a remote beacon into gray scale and contour data. Multiple frames of the image, including the gray scale and contour data are buffered. The beacon image is reconstructed from the buffered frames, which include blur data related to the beacon image. A position of the beacon is measured from the buffered frames. The blur data are analyzed to generate a blur vector. The beacon position and blur vector are processed to generate navigation information based on the beacon.
