Curating boats can be difficult. They are complex structures, often demanding to conserve whether in or out of the water; they are usually large, difficult to move on land, and demanding of gallery space. Communicating life on board to a visiting public in the terra firma context of a museum can be difficult. Boats in their native environment are i...

In recent years, researchers in the field of natural heritage have intensified their efforts to develop new ways to enhance the promotion and accessibility of natural content in order to attract more audiences using virtual representations of physical objects (digital twins). Therefore, they are increasingly incorporating new technologies and digital tools in their operations since their usage by the general public and in the natural heritage (NH) museums is considered particularly effective. Simultaneously, the increasing quality of the produced digitizations has opened up new opportunities for the exploitation of the outcomes of digitization beyond the initial anticipations. Responding to the growing demand of museum visitors for a personalized digital tour experience, especially amidst the recent COVID-19 pandemic, the v-PalM project aims to develop a digital platform to offer virtual guidance and education services at the Museum of Paleontology and Geology, which is hosted at the National Kapodistrian University of Athens. The development of the platform will be based on collecting data through various methods, including crowdsourcing, innovative information, and communication technologies, taking advantage of content digitization using 3D scanning devices. This paper demonstrates an enhanced methodology for the digitization of paleontological exhibits. The methodology uses photogrammetry and laser scanning methods from various devices, such as drones, laser scanners, and smartphones. These methods create digital twins that are suitable for various scenarios, including research, education, and entertainment. The proposed methodology has been applied to over fifty paleontological museum exhibits of varying sizes and complexities, and the resulting 3D models exhibit high accuracy in both their material and geometric aspects, while they also feature crucial details that assist researchers and the scientific community.

In recent years, researchers in the field of cultural heritage have intensified their efforts to develop new ways to enhance the promotion and accessibility of cultural content in order to attract more audiences using virtual representations of physical objects (digital twins). Therefore, they increasingly include new technologies and digital tools in their operation, since their application both to the general public and among the cultural organisations themselves, is considered particularly effective. Simultaneously, the increasing quality of the produced digitizations has opened up new opportunities for further exploitation of digitization outcomes in a broader context than was initially anticipated. Responding to the growing demand of museum visitors for a personalized digital tour experience, especially in the midst of the recent Covid-2019 pandemic, the v-PalM project aims to develop a digital platform for offering virtual guidance and education services at the Museum of Paleontology and Geology that is hosted at the National Kapodistrian University of Athens. The development of the platform will be based on collecting data through several methods including crowdsourcing, innovative information and communication technologies, taking advantage of content digitization using 3D scanning devices. In this paper, we demonstrate a methodology for the digitization of paleontological findings that can be used for creating digital twins suitable for various scenarios including research, education, and entertainment.
... With the improvement of 3D data acquisition capabilities 1-3 , point cloud models are gaining increasing attention and being widely utilized in many fields, such as scene reconstruction [4][5][6][7][8][9] , museum display [10][11][12][13] , and virtual projection [14][15][16][17][18] . High precision of the 3D scanning technology can provide abundant details of the point clouds, but it will simultaneously generate a mass of redundant data, which seriously reduces the efficiency of data processing, transmission and display, thereby affecting subsequent applications. ...
To obtain a higher simplification rate while retaining geometric features, a simplification framework for the point cloud is proposed. Firstly, multi-angle images of the original point cloud are obtained with a virtual camera. Then, feature lines of each image are extracted by deep neural network. Furthermore, according to the proposed mapping relationship between the acquired 2D feature lines and original point cloud, feature points of the point cloud are extracted automatically. Finally, the simplified point cloud is obtained by fusing feature points and simplified non-feature points. The proposed simplification method is applied to four data sets and compared with the other six algorithms. The experimental results demonstrate that our proposed simplification method has the superiority in terms of both retaining geometric features and high simplification rate.
... Aside from buildings and terrestrial sites, some naval artifacts are considered of great heritage value, and it is of great difficulty to display and effectively disseminate a multitude of naval vehicles out of their context (water masses) in museums. Accordingly, Wetherelt, Cooper, and Zazzaro (2014) processed the LiDAR high density point cloud and generated photorealistic and accurate 3D digital models for the dhows. Their work is displayed in 2D, 3D, and virtual visualization in the National Museum of Qatar. ...
Preservation of heritage buildings should be carried out to get a better understanding of the behavior of their structures and keep them in a good condition. As such, corrective diagnosis of heritage buildings health conditions would help to identify potential risks and take remedy actions. This paper presents a framework for heritage Building Information Modeling (HBIM) application in Egyptian Heritage buildings. The framework is capable of utilizing processed point clouds using 3D laser scanning to create different purpose BIM models at the different levels of development to simulate the structural performances under different types of actions. The paper illustrates an extensive structural analysis for Tosson palace in Cairo – Egypt to assess its health state to assure its sustainability for future use.

Many buildings were built on more ancient remnants of heritage buildings, some others incubate and surrounds older structures. Sharing and documenting knowledge about elder hidden buildings whether inside newer structures or be-neath them is a good contribution to the cultural heritage of the building’s region and era. In this research the authors will introduce a framework to document, share and manage information about the apparent heritage remnants of elder structures. The framework harnesses the power of LiDAR and HBIM technologies. This frame-work is intended to support documenting the current state and provide basis for fu-ture development around ancient sites/buildings while considering keeping the old-er remnants visible and intact. A case study is introduced that involves a Basilica renovation of an ancient site in Minya-upper Egypt; being a heritage site with large ancient remnants from different eras. There is a plan to build a modern muse-um/exhibition around the heritage site containing the ancient remnants on their cur-rent position, with the purpose of preservation and exhibition. The modern structures shall follow the proposed framework to keep the remnants structurally and contextu-ally intact while providing the intended new functionality.
