摘要：Nowadays digital photogrammetry has become one of the most efficient techniques for Heritage documentation. The creation of three-dimensional models from images taken with digital cameras is the usual procedure. The aim of this paper is showing the results obtained by photogrammetric analysis of library pictures, taken mainly in archaeological excavations, to recover three-dimensional information that maybe latent, although the shots had not been made with the purpose of creating 3D models. In this way we have generated three-dimensional models in which can be recovered geometric data that were not reflected in the drawings or photographs made during fieldwork.
