Landing operations for small agricultural helicopters and, in general, docking operations between two vehicles, constitute an ongoing engineering challenge. This is due, in part, to the lack of small-sized and reliable local navigation system. This paper proposes a new, vision-based local navigation system that enables 6 degrees-of-freedom navigation for landing small airborne vehicles. The salient feature of our system is the design of a target that generates easily visible interference fringes, along with easily recognizable features. Following the theoretical aspects to our design, we describe a limited experiment showing the efficacy of our design.
