We present the results of a point-cloud-based survey deriving from the use of image-based techniques, in particular with multi-image monoscopic digital photogrammetry systems and software, the so-called structure-from-motion technique. The aim is to evaluate the advantages and limitations of such procedures in architectural surveying, particularly in conditions that are at the limit. A particular case study was chosen: the courtyard of Palazzo dei Capitani del Popolo in Ascoli Piceno, Italy, which can be considered the ideal example due to its notable vertical, rather than horizontal, layout. In this context, by comparing and evaluating the different results, we present experimentation regarding this single case study with the aim of identifying the best workflow to realise a complex, articulated set of representations-using 3D modelling and 2D processing-necessary to correctly document the particular characteristics of such an architectural object.
