Balancing Design Freedom and Constraints in Wall Posters Masquerading as AR Tracking Markers
This paper describes how to construct a mixed reality (MR) environment by adopting a geometric registration method using visually unobtrusive flat posters on the wall. The proposed method is one of the several approaches of the semi-fiducial invisibly coded symbols (SFINCS) research project, the purpose of which is achieving a good balance between elegance with regard to the environment and robust registration. In this method, posters tentatively used for geometric registration are designed to blend with the environment. However, they are recognized as markers based on certain design rules. Posters in a real scene can be found in real time using these design rules. This paper introduces procedures for developing poster design rules using toolkits developed by us.
