We present a system for UAV automated landing that requires minimal landing site preparation, no additional electronics, and no additional aircraft equipment of any kind. This is a Joint-UAV solution that will work equally well for land-based aircraft and for shipboard recoveries. Our proposed system requires only a simple target that can be permanently painted on a runway, laid out in a roll-up mat, or potentially denoted with chemical lights for night operations. Its appearance is unique when seen from the optimal approach path, and from other angles its perspective distortion indicates the necessary correction. By making continual adjustments based on this feedback, the plane can land in a small area at the desired angle. We time the pre-touchdown flare using only a 2D visual reference. Assuming a constant closing speed, we can estimate the time to contact and initiate a controlled flare at a predetermined interval.
