Hybrid Technique to Support the Tracking in Unstructured Augmented Reality Environments

In this paper, we present a new Augmented Reality (AR) tracking technique that integrates the marker-based tracking with the tracking ability of a commercial mobile robot. The role of the mobile robot is to co-work with the user for extending the working space of the marker-based tracking technique. The robot follows the user’s movements during the exploration in the AR environment and updates the position of a fiducial marker, which is fixed on it. The robot is automatically controlled through the device used to visualize the AR scene. The paper discusses the issues related to the integration of these two tracking techniques and proposes an AR application, which has been developed to demonstrate the feasibility of our approach. Technical issues and performances have been assessed through several testing sessions.Copyright © 2012 by ASME
