“…Photogrammetry is a survey technique based on the triangulation principle, through which a set of photos taken from different viewpoints are turned into 3D models [24,25]. The transformation of images into a 3D model is the result of a complex procedure involving specific computer vision algorithms (e.g., structure from motion) that are able to collimate common points from a set of convergent and overlapping photos and, thus, to reconstruct the position, the shape and the size of the scene taken in investigations [26][27][28]. UAV photogrammetry is currently the most popular in architecture and archaeology, used to create digital maps, texture, 3D models, calculate volume and document historical buildings, thanks to the possibility of using low-cost instruments.…”

In the coming years, Italy will need to take on a great challenge concerning the digitization of its archaeological and architectural heritage, one of the richest and most problematic in the world. The aim is to improve the knowledge, conservation, enhancement and accessibility of cultural assets and to make them a resource for national and local development. In this process, the next generation of 3D survey methods (laser scanning and photogrammetry), in combination with diagnostic techniques (spectroscopy analyses) and GIS/BIM (Geographic Information System/Building Information Modeling) solutions, represent a valid support. This work, part of a broader intervention launched by the Municipality of Reggio Calabria for the requalification of some archaeological sites located within its urban and metropolitan area, is focused on the study case of Motta S. Agata. The ancient settlement is located 8 km from Reggio C. in a hilly area difficult to reach and preserves numerous structures in a state of ruin. Among these, two interesting medieval churches are proposed for examination: the church of San Nicola, characterized by five hypogeal funeral crypts, and the chapel of San Basilio, which preserves the traces of a wall painting. A multi-methodological approach including close-range photogrammetry, laser scanning and chemical and thermal analyses was adopted in order to fulfill different tasks: creating a topographic model of the hillfort, mapping the archaeological evidence, digitizing and returning 3D models of the churches, characterizing materials through chemical analyses and monitoring the surfaces with thermal imaging. These combined applications have contributed to reaching the planned goals, i.e., study, conservation, diagnostics, preparation for restoration interventions, development of digital media and dissemination. In this way, a type of interactive museum (made up of virtual tours and informative digital models) has been made available in order to improve the site’s accessibility and inclusivity as well as to test the effect of digitization in attracting tourists and local people toward a place located outside of the usual tourist circuits.

“…Fusion approaches introduced for multisource point cloud (3D-to-3D) registration (and successively coloring) are: manual annotation of common features [251], iterative closest point (ICP) [252,253], feature-based [254], and georeferencing-based [35]. The rapid increase in the implementation of unmanned aerial systems (UAS) for cultural heritage IBM has recently introduced fascinating integrative approaches, on the convergence of TLS and low-altitude aerial photogrammetry [255][256][257][258][259] (see Section 4.1).…”

Built cultural heritage is under constant threat due to environmental pressures, anthropogenic damages, and interventions. Understanding the preservation state of monuments and historical structures, and the factors that alter their architectural and structural characteristics through time, is crucial for ensuring their protection. Therefore, inspection and monitoring techniques are essential for heritage preservation, as they enable knowledge about the altering factors that put built cultural heritage at risk, by recording their immediate effects on monuments and historic structures. Nondestructive evaluations with close-range sensing techniques play a crucial role in monitoring. However, data recorded by different sensors are frequently processed separately, which hinders integrated use, visualization, and interpretation. This article’s aim is twofold: i) to present an overview of close-range sensing techniques frequently applied to evaluate built heritage conditions, and ii) to review the progress made regarding the fusion of multi-sensor data recorded by them. Particular emphasis is given to the integration of data from metric surveying and from recording techniques that are traditionally non-metric. The article attempts to shed light on the problems of the individual and integrated use of image-based modeling, laser scanning, thermography, multispectral imaging, ground penetrating radar, and ultrasonic testing, giving heritage practitioners a point of reference for the successful implementation of multidisciplinary approaches for built cultural heritage scientific investigations.

“…Photogrammetric techniques rely on images taken from different viewpoints to record the 3D geometry of a building or objects (Dore and Murphy, 2017). As these techniques are quick and easy to use, and the costs of devices are relatively low (Altman et al, 2017;Brilakis et al, 2010;Dobelis et al, 2016;Ulvi, 2021;Yang et al, 2020), the recording of existing buildings by photogrammetry has increased recently (Dore and Murphy, 2017;Yang et al, 2020). Even though photogrammetry has several advantages compared to laser scanning, including high-quality imagery and colour information (Dore and Murphy, 2017), there are also multiple challenges related to this technique.…”

“…Even though photogrammetry has several advantages compared to laser scanning, including high-quality imagery and colour information (Dore and Murphy, 2017), there are also multiple challenges related to this technique. The main difficulties include a time-consuming computational data process (Dore and Murphy, 2017;Fassi et al, 2013;Ulvi, 2021), less accurate and dense point clouds than a laser scanner can provide (Altman et al, 2017;Golparvar-Fard et al, 2011;Lee et al, 2015;Mellado et al, 2020;Ulvi, 2021), and the requirement of proper lighting (Rocha et al, 2020). For overriding the challenge of a laborious data process, photogrammetric techniques are evolving towards automatic post processing (Aicardi et al, 2018;Dore and Murphy, 2017).…”

The use of the laser scanning technique has increased rapidly in the field of built environment, mainly because it produces highly accurate as-built data. However, the full potential of this technique is utilised only limitedly in building refurbishment projects. This research aims to investigate the barriers to the implementation of laser scanning in building refurbishment projects in Finland. Qualitative interviews were carried out to identify these barriers, and furthermore, to explore the current usage of the technique in building refurbishments. The study shows that many obstacles to implementations are related to challenges in laser scanning procurement, including a low level of competence in acquisition, limitations of the laser scanning technique in building refurbishments, and limitations and challenges in utilising the data in design work. This study is beneficial for building owners and practitioners as it presents the challenges and advantages that laser scanning can provide a refurbishment project. In addition, it offers suggestions to improve the early phase of a refurbishment project in order to achieve greater benefits with laser scanning. Furthermore, the findings may be utilised in the procurement process of laser scanning services in such projects, and the results may potentially solve practical challenges encountered in laser scanning work.
