[POSTER] Overlaying Navigation Signs on a Road Surface Using a Head-Up Display

Abstract

In this paper, we propose a method for overlaying navigation signs on a road surface and displaying them on a head-up display (HUD). Accurate overlaying is realized by measuring 3D data of the surface in real time using a depth camera. In addition, the effect of head movement is reduced by performing face tracking with a camera that is placed in front of the HUD, and by performing distortion correction of projection images according to the driver's viewpoint position. Using an experimental system, we conducted an experiment to display a navigation sign and confirmed that the sign is overlaid on a surface. We also confirmed that the sign looks to be fixed on the surface in real space.
