Abstract

It is essential for car drivers to obtain sufficient visual information, but the dead angle caused by the pillar is often a problem to ensure the safety. In order to solve this problem, optical camouflage technologies using a retro-reflective projection technology is a promising approach. However, it is difficult for the driver to wear a head-mounted projector. Therefore we have proposed the method to separate a projector from the driver's head. In our method, a screen attached to the front pillars should have characteristics to reduce the influence of the variance of environment light while maintaining high contrast in the vertical direction. In this study, the authors measured the luminance of the projected image on a white screen, beads type retroreflector, prism type retroreflector, and beads type retroreflector covered with a diffuser. The results show that beads type retroreflector covered with a diffuser is effective for this method.
