Abstract

Aerial display provides a new field for signage because the aerial display forms a real image without no hardware at the image position [1, 2]. Our goal is to realize aerial LED signage that is shown at desired 3D locations, for example, in front of cars and people's faces. In the previous work, we have realized aerial LED display. However, the previous setup has an occlusion problem, that is, inconsistency between occlusions and depths. In this paper, we propose a new optical setup to solve the occlusion problem in multi-layered LED display.
