“…Heritage documentation is seen as the systematic collection and archiving of tangible and intangible elements of historic structures and environments. Its purpose is to supply accurate information that will enable correct conservation, monitoring and maintenance for the survival of the building (Dore and Murphy, 2017) (Letellier, 2007) (Bryan et al, 2009).…”

Abstract. Heritage BIM can represent many advantages for heritage building documentation, restoration, retrofitting and management. However, the most complicated challenge concerning H-BIM is the inevitability of starting at an intermediate point in the asset’s life cycle, which can be much more complex than the relatively straightforward cradle-to-grave model that describes new-build construction (Historic England, 2017). This leads to irregular geometry, non-homogeneous materials, variable morphology, not documented changes, damage and various stages of construction. These challenges put more weight on the surveying, documentation, modelling and visualisation phase within the process of HBIM.Many investigation tools can be used and combined to document and investigate the fabric of historic buildings. This paper reviews the literature and the state of art of the different domains of data that could be included in the documentation and investigation process of the built heritage, in order to assess the breadth and depth by which heritage buildings can be documented. These data can vary from outer geometry survey, to sub-surface materials and structural integrity investigations, to data concerning the building performance, as well as the historic records concerning the building`s morphology over time, which can help to create a more in-depth knowledge about the heritage buildings` status and performance and can create a solid base for any required restoration and retrofitting processes.

“…Table shows the IOPs for the principal distance, c , and principal point, x 0 and y 0 , estimated for these experiments and the respective estimated standard deviations σ . Standard deviations of the estimated principal distance and estimated principal point coordinates, for all approaches, were less than 1 pixel (0·005 mm) for both sensors, as recommended for close range photogrammetry applications (Bryan et al., ; Campos et al., ). These results have an accuracy comparable to conventional camera calibration with perspective cameras, which shows the importance of a correct mathematical model to describe the camera's inner geometry for non‐conventional sensors.…”

This paper presents a technique for the calibration of a 360°dual imaging system (Ricoh Theta S) composed of two cameras with fisheye lenses specially mounted in a common structure. The experiments are based on calibration with a bundle adjustment using the equidistant fisheye lens model and relative orientation stability constraints, such as distance, base elements and rotation matrix between individual cameras' coordinate systems. As a result, an equidistant mathematical model using the Conrady-Brown lens distortion model was shown to be suitable for estimating the interior and relative orientation parameters of the Ricoh Theta S. The main contribution presented in this work is a simultaneous bundle adjustment approach with stability constraints on base elements and rotation matrix angles, which achieved accuracies comparable with conventional photogrammetric calibration with perspective cameras.

“…Points cloud is demonstrated as the state of art format in the recording of architectural heritage: several and robust tools are growing up in image-based techniques (Siebke et al, 2018) (Schonberger and Frahm, 2016), as well as, some years ago, was demonstrated in range based acquisitions (Bryan et al, 2013). Recently, studies focus on the exploitation of point clouds out challenging their current boundaries: in architectural heritage documentation certainly, the major challenge is to perform workflow able to give information dealing with conservation or restoration purposes.…”

Abstract. In the last few years, the evolution of acquisition techniques allowed to acquire reality-based models increasing accurate and rich of information. On the contrary, the ability to exploit the acquired data in the most efficient, economic (in terms of invested time), and impartial way (in terms of arbitrary choices of the operator) represents the most significant gap. Interoperability theme between points cloud and informative systems becomes relevant. Excellent results were achieved in 3D data exploitation in HBIM and GIS environments, as well as in VR and AR applications, whereas the structural analysis with the Finite Element Method (FEM) still lacks robust workflows based on point clouds. The present paper proposes a methodology allowing to transform the TLS point cloud obtained from the survey directly into a 3D FEM, in a semi-automatic way and, therefore, proposes a hybrid reverse engineering approach that aims to: (i) maximizing the correspondence between the model for structural analysis and the real object; (ii) minimizing the time and the operator’s decision. The strategy is validated on the belfry of the Metropolitan Cathedral-Basilica of Saint Cyriacus in Ancona, Central Italy. The reliability of the proposed model is assessed through a comparison between the model obtained from the Boolean modelling within a FEM software and the model obtained directly from points cloud processing. The comparison between the two numerical models highlights the enormous potential of the exposed method. The proposed case study shows how it is possible to develop high-quality 3D models, able to connect geometrical-historical survey with thematic analysis about structural behavior.
