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

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.
