“…Usually, a DSLR camera is used in the most of photogrammetric surveys for the documentation of Cultural Heritage even though new low-cost digital sensors have been recently tested. In fact, there has been a rapid development of testing especially spherical photogrammetry applied to Cultural Heritage, both for purely commercial purposes and for tourism promotion, but also for three-dimensional metric documentation (Fangi 2017;Kwiatek et al 2015;Barazzetti et al 2018;Gottardi et al 2018;Fangi 2006). One of the main advantages of using spherical panoramas concerns their implementation in virtual reality tools: up to now, there are different procedures to generate a virtual environment using various input data, software and devices.…”

Abstract. The deep knowledge of Cultural Heritage, with historical research and interpretative analysis of materials, is fundamental to know the state of conservation and to plan potential restoration interventions. In the last years, thanks to the fast and continuous technological development, the metrical survey had a significant increase in this particular field: in fact, 3D digital acquisition allows to study some aspects otherwise difficult to investigate in a detailed way.In this research, we will explain the methodology used for the ceiling’s survey of the Sala Capitolare of the Scuola Grande di San Rocco in Venice, focusing on the support structure of Tintoretto’s paintings, anchored to a wooden system of Palladian trusses. The complexity of this Venetian architecture, its considerable dimension, the richness of decorations and the particular lighting conditions provided the opportunity of thinking about unconventional choices to apply from time to time and they required the integration of different methodologies: the laser scanning survey and the photogrammetric acquisition, together with a topographic network, allowed to obtain an adequate metric result for the study of the structure in its entirety. Furthermore, it was also decided to test image acquisition with a spherical camera for the documentation of the analysed architecture: this type of information, more related to a viewable aspect than to a metric one, can be presented together with traditional 2D representations to ensure a better enhancement of the achieved results.

“…The solution to such issues is nowadays represented by new sensors that, at the expenses of resolution, enable to collect spherical images with just one shot. In (Kwiatek and Tokarczyk, 2015) and (Kwiatek and Tokarczyk, 2014) the topic of exploiting 360 images for photogrammetric purposes is faced. The articles attempt to describe a procedure for using images coming from a video sequences, highlighting that the images have a relatively low resolution.…”

During the last few years, there has been a growing exploitation of consumer-grade cameras allowing one to capture 360&deg; images. Each device has different features and the choice should be entrusted on the use and the expected final output. The interest on such technology within the research community is related to its use versatility, enabling the user to capture the world with an omnidirectional view with just one shot. The potential is huge and the literature presents many use cases in several research domains, spanning from retail to construction, from tourism to immersive virtual reality solutions. However, the domain that could the most benefit is Cultural Heritage (CH), since these sensors are particularly suitable for documenting a real scene with architectural detail. Following the previous researches conducted by Fangi, which introduced its own methodology called Spherical Photogrammetry (SP), the aim of this paper is to present some tests conducted with the omni-camera Panono 360&deg; which reach a final resolution comparable with a traditional camera and to validate, after almost ten years from the first experiment, its reliability for architectural surveying purposes. Tests have been conducted choosing as study cases Santa Maria della Piazza and San Francesco alle scale Churches in Ancona, Italy, since they were previously surveyed and documented with SP methodology. In this way, it has been possible to validate the accuracy of the new survey, performed by means an omni-camera, compared with the previous one for both outdoor and indoor scenario. The core idea behind this work is to validate if this new sensor can replace the standard image collection phase, speeding up the process, assuring at the same time the final accuracy of the survey. The experiment conducted demonstrate that, w.r.t. the SP methodology developed so far, the main advantage in using 360&deg;&thinsp;omni-directional cameras lies on increasing the rapidity of acquisition and panorama creation phases. Moreover, in order to foresee the implications that a wide adoption of fast and agile tools of acquisition could bring within the CH domain, points cloud have been generated with the same panoramas and visualized in a WEB application, to allow a result dissemination between the users.

“…The potential in extracting information automatically has also been explored, an example being mapping out road sign location using computer vision within Street View [16]. Within the area of BIM, more advanced 3D models can be generated using photogrammetry and further used as a tool to compare deviation of buildings from the 'as-built' to 'designed as' models [17][18].…”

The use of Mixed Reality (MR) tools can improve information retrieval, collaboration and decision making, thus aiding the management of buildings within the operation and maintenance (O&M) lifecycle stages. In this paper, we focus on the use of MR in visualising BIM data to aid building lifecycle management. This paper compares current and emerging MR tools and explores their potential in being applied to O&M of Small and Medium Enterprises (SMEs). MR refers to technology that enhances reality by integrating it with the digital world, such as Augmented Reality (AR), Virtual Reality (VR) and spherical panoramas, known as Photospheres. Current literature on applications and limitations of MR in the O&M cycle for small businesses is explored and the user requirements for implementation and use are elicited. Key requirements are found to be cost, skill level, interoperability, prerequisite data, interactivity and time. Using these requirements, the state-of-the-art in VR, AR and Photosphere environments is assessed and the contexts in which they are most appropriate are developed. The paper concludes with a number of recommendations for the selection of an appropriate strategy dependent on the maturity of BIM adoption within an enterprise. A number of theoretical and conceptual implications are also developed.
