OVERVIEW

This course presents the basics of Augmented Reality, considering both the Computer Vision aspects necessary to build knowledge of real environments and the technical elements necessary to develop AR applications. The main software framework for the development of AR applications will be presented, always referring to the theoretical aspects and background

AIMS AND CONTENT

LEARNING OUTCOMES

Learning the theoretical and methodological fundamentals of Augmented Reality, from the concepts of 3D Computational Vision to model the real-world world, to the synthesis of the virtual environments, and their fusion.
