Use of Augmented Reality in Geosimulators

Abstract

This thesis aims to extend the Geo2000 technology towards use in outdoor field work and logistics. To accomplish this goal we make use of augmented reality (AR). Integrating and adapting technology as GPS, gyroscope and head mounted displays is an important part of the work. A description of the Geo2000 concept and technology is also given. Functionality for operating on data as tracks, waypoints and images with positioning data inbound have been developed using iterative design and implementation. As well as 3D moving map functionality for assisting navigation with e.g. car, helicopter, snowmobile or tracked vehicle. A method for using a 3D search grid in Search and Rescue operations is also a part of this work. The thesis work involves a lot of field work on Svalbard, which has given feedback to further development and improvements. The problem of fitting virtual and real world together has been explored both empirically and theoretically, and two methods to solve the problem have been suggested. Correction for the earth curvature is essential in getting a correct view and is discussed. The results presented has been successfully included into the Geo2000 simulator SvalSim.
