Monitor-Based tracking system for Wide Augmented Reality Environments

Abstract

In Augmented Reality (AR) applications, the technological solutions used for tracking objects in the real environment are generally related to the conditions of the environment and to the application purposes. The selection of the most suitable tracking technology satisfies the best compromise among several issues including performance, accuracy and easiness of use. This paper describes an AR tracking approach based on a marker-based tracking and its development for wide environment by displaying itself on a monitor. This solution allows us to improve the visibility of the marker and the tracking, thanks to a dynamic control of marker s dimensions. The technical features and performances of our approach have been assessed by several testing sessions focused on comparative analyses.
