Summary

The aim of augmented reality (AR) is to increase user perception by adding information, such as sound, textual notations or virtual objects to a perceived scene. By its very nature, AR is interactive and three-dimensional (3D), meaning that at any time, added elements must be correctly placed in relation to the real world as seen by the user. This chapter discusses the state of the art of two key points in AR: (i) real-time pose computation including pose computation requirements and image/model mapping, and (ii) the acquisition of a scene model including generation of 3D models such as offline modeling and online modeling, in the common framework of monocular vision.
