Abstract
Disclosed herein is a method that comprises acquiring one or more images of a plurality of markers of an off-board target using a camera onboard a rotorcraft, the plurality of markers arranged in a predefined pattern. The method also comprises processing, using an image processor, the one or more images of the plurality of markers to identify the predefined pattern of the plurality of markers. The method further comprises determining guidance information for the rotorcraft relative to the off-board target based on the identified predefined pattern of the plurality of markers, an orientation of the plurality of markers and a relative spacing of the plurality of markers. The method additionally comprises providing the determined guidance information to a display device within a field of view of an operator of the rotorcraft.
