    Integrated position and attitude determination for augmented reality systems
    Scott-Young, Stephen ( 2004-10)
    One of the most challenging tasks for augmented reality systems is that of position and attitude determination in outdoor unprepared environments. Augmented reality, a technology that overlays digital information with views of the real world, requires accurate and precise position and attitude determination to operate effectively. For small (often indoor) areas, careful preparation of the environment can allow for augmented reality systems to work successfully. In large outdoor environments, however, such preparation is often impractical, time-consuming and costly. This thesis aims to investigate the development of a position and attitude determination component for augmented reality systems capable of operation in outdoor unprepared environments. The hypothesis tested in this investigation is that the integration of Global Positioning System (GPS), Dead Reckoning (DR) and map matching techniques enables the continuous and accurate real-time visual alignment of three-dimensional data with objects in the perspective view of a user operating in outdoor unprepared environments.
