AR Guide System Using Mobile Projector in Indoor Environment

Abstract

This pager proposes a projection-based AR guide system which guides users using a mobile projector in indoor environment. The projection-based AR guide system projects guidance of exhibits onto walls or floors in the real world. In order to realize this system, it is necessary to measure a position and an orientation of the projector precisely in a wide area. In the proposed guide system, the projector's position is estimated from images capturing invisible markers which are set up on ceilings with an infrared camera attached to the projector. In addition, to indicate the guide information intuitively for users, the proposed system displays information at three dimensional position using two projectors and polarized glasses.
