Space mapping is an integral part of architecture, whose basic tools change constantly thanks to technology, expensive or/and bulky tools being the modern protagonists of this dynamic process especially when high precision is required. The study at hand aims at investigating whether a mobile phone is capable of providing the necessary information to photogrammetric programs in sufficient time, in order to produce an interior 3D model that can subsequently be used as a lighting analysis model or further employed in energy studies. The use of the mobile phone instead of another photographic medium was also chosen in order to explore the option of mapping at low cost to the user.

In the first part of the study the various basic methods of mapping that exist to date are described, along with the contribution of photogrammetry in fields outside architecture. The second part of the study deals with the detailed description of the experiments carried out with the mobile phone and their comparison with the standard mapping method.
