“…Stereo systems have been used for numerous underwater applications such as robotic control (Sagara et al, 2013), archeology (Liarokapis et al, 2017), and surveying (Williams et al, 2016). These systems consist of two horizontally displaced cameras that simultaneously photograph a scene from slightly different perspectives.…”

“…The authors found that the performance of the PMVSbased stereo-matching technique declines markedly in high turbidity conditions. Liarokapis et al (2017) used PhotoScan R (Agisoft, St. Petersburg, Russia), a state-of-the-art commercially available software package, for 3D modeling and mapping of underwater archaeology sites. Agisoft's PhotoScan R handles all stages of the 3D reconstruction pipeline, including the dense multiview stereo-matching stage.…”

Underwater inspections stand to gain from using stereo imaging systems to collect three‐dimensional measurements. Although many stereo‐matching algorithms have been devised to solve the correspondence problem, that is, find the same points in multiple images, these algorithms often perform poorly when applied to images of underwater scenes due to the poor visibility and the complex underwater light field. This article presents a new stereo‐matching algorithm, called PaLPaBEL (Pyramidal Loopy Propagated BELief) that is designed to operate on challenging imagery. At its core, PaLPaBEL is a semiglobal method based on a loopy belief propagation message passing algorithm applied on a Markov random field. A pyramidal scheme is adopted that enables wide disparity ranges and high‐resolution images to be handled efficiently. For performance evaluation, PaLPaBEL is applied to underwater stereo images captured under various visibility conditions in a laboratory setting, and to synthetic imagery created in a virtual underwater environment. The technique is also demonstrated on stereo images obtained from a real‐world inspection. The successful results indicate that PaLPaBEL is well suited for underwater application and has value as a tool for the cost‐effective inspection of marine structures.

“…One of the most promising and popular technologies that provides the user with an integration of digital contents with real images is augmented reality (AR) (Vecchio et al, 2015). Unlike land sites, semi (/or fully) submerged settlements, ancient ports, shipwrecks and coastal instatements are not accessible to public due to their special (sub) marine environment and depth (Liarokapis et al, 2017). Through the remarkable achievements in digital technologies, including wireless communications and smart devices, the exploitation of AR models is now feasible, in order to provide a better understanding of coastal and underwater cultural heritage assets.…”

Abstract. Τhe development in the fields of Underwater Cultural Heritage (UCH) management and Maritime Archaeology, yields an interdisciplinary and creative academic framework, such as the Information and Communication Technologies (ICT) sector that has been proved to build intelligent systems and applications. However, the ways to fully make use of these technologies are still being explored, as their potential have not been exploited yet. Underwater archaeological sites, semi (/or fully) submerged settlements, ancient ports and shipwrecks, unlike land sites, are not accessible to public due to their special (sub) marine environment and depth. In this paper, an innovative research idea of using Augmented Reality (AR) for maintaining the memory and the information of underwater archaeological sites, is presented. Although the “artificial” visual documentation cannot replace the authentic values of the underwater tangible heritage, the AR technology can contribute to the protection of the intangible properties and the conquered knowledge of the past of a place. This research work will focus, among other case studies, on the (semi) submerged fortifications and their contiguous contents of the acropolis of Halai in east Lokris, Greece. Hence, along with the climate change that may lead more antiquities covered by water during the following years, the advances in the communication field and the up-coming 5G and cloud technologies will make the idea fully applicable, contributing to the enhancement of the coastal and the underwater archaeological remains.

“…Among the digital technologies, Virtual Reality (VR) has proven its effectiveness in increasing the value of cultural heritage and in the last years it has been efficiently applied for the visualization and exploitation of the UCH (Chapman et al, 2006;Liarokapis et al, 2017;Bruno et al, 2016Bruno et al, , 2018. In fact, VR technology can be efficiently applied to this field in order to make underwater archaeological sites the most accessible to the general public without any constraint given by distance, depth or time.…”

Abstract. The paper presents the application of some Virtual Reality technologies developed in the Horizon 2020 i-MARECulture project to the case study of the sunken “Villa con ingresso a protiro”, dated around the II century AD, and located in the Marine Protected Area - Underwater Park of Baiae (Naples).The i-MARECulture project (www.imareculture.eu), in fact, aims to improve the public awareness about the underwater cultural heritage by developing new tool and techniques that take advantage of the virtual reality technologies to allow the general public to explore the archaeological remains outside of the submerged environment.To this end, the paper details the techniques and methods adopted for the development of an immersive virtual tour that allow users to explore, through a storytelling experience, a virtual replica and a 3D hypothetical reconstruction of the complex of the “Villa con ingresso a protiro”.
