This paper introduces a simple system to provide relative position between a base unit
and an active unit. The proposed system is directional and allows the active unit to
approach or depart from the base unit along a linear path, determined by the orientation
of the base unit. The system does not require a data link between the base and the active
unit, just a clear line of sight. The proposed system utilizes monocular vision on the
active unit and requires the availability of enough computational power to perform
simple computer vision algorithms.
Part I describes the physical characteristics of the beacon utilized on the base unit, Part
II describes the algorithms utilized to compute the relative position of the active unit to
the base, utilizing the vision data. Part III presents simulation results. Part IV discusses
the results and findings and proposes future work.
