In the field of monoscopic, multi-image digital photogrammetry, a structure-from-motion system is the set of applications that use rendering methods of more than one native digital snapshot and most of the rendering is done with automatised procedures. In these systems, the development of algorithms, computer vision in particular, has allowed the different phases to be automatised: from the orientation phase, including auto-calibration, to the more or less dense point-cloud-extraction phase according to determined accuracy criteria, from which a texturised model can also be obtained.

Abstract
The goal of this paper is to focus on multi-image monoscopic digital photogrammetry, illustrating several types of applications used in a single case study chosen for its unique characteristics: Palazzo dei Capitani del Popolo in the main square in the old town centre of Ascoli Piceno. The description of this experimentation will be illustrated in the paper not only to assess the potential and limits of these systems, but also to place them in a scientific context and recall the theoretical fundamentals of this method, since we believe these in-depth studies to be increasingly necessary in order for these digital technologies to be used properly.
