Though noticeable development in the recent few years, the availability of 3D subjects is still shadowed by that of its 2D equivalent, many 2D-to-3D images, and video conversion methods have been exposed. Techniques that have human operators are mostly fruitful but also time-consuming and expensive, methods that classically make use of a deterministic 3D model, have not yet attained an equal range of excellence for they depend on hypotheses that are frequently disrupted in practical. In this paper, we put forth a new flair of methods that are based on a profoundly unalike line of attack to learn the 2D-to-3D conversion from paradigms. We demonstrate both the value and the computational efficiency of our methods on abundant 2Dimagesand discuss their limitations and remunerations.

In the heritage field, the demand for fast and efficient 3D digitization technologies for historic remains is increasing. Besides, 3D digitization has proved to be a promising approach to enable precise reconstructions of objects. Yet, unlike the digital acquisition of cultural goods in 2D widely used today, 3D digitization often still requires a significant investment of time and money. To make it more widely available to heritage institutions, the <em>Competence Center for Cultural Heritage Digitization</em> at the <em>Fraunhofer Institute for Computer Graphics Research IGD</em> has developed <em>CultLab3D</em>, the world’s first 3D mass digitization facility for collections of three-dimensional objects. <em>CultLab3D</em> is specifically designed to automate the entire 3D digitization process thus allowing to scan and archive objects on a large-scale. Moreover, scanning and lighting technologies are combined to capture the exact geometry, texture, and optical material properties of artefacts to produce highly accurate photo-realistic representations. The unique setup allows to shorten the time needed for digitization to several minutes per artefact instead of hours, as required by conventional 3D scanning methods.

The paper explores the application of a non-contact measurement technique - optical 3D digitization (active triangulation/structured light method) - for determining the dimensions (outer and inner diameters) of seamless cold-drawn steel tubes. The paper focuses on three areas of steel tube measurement by 3D digitization: (1) evaluation of the measured values using two different measuring volumes, (2) evaluation of the measured values with different 3D digitization parameter settings, (3) Computer Aided Design (CAD) comparison. The outcomes of the measurements and insights gained provide valuable guidance in selecting the appropriate 3D digitization method for seamless steel tube measurement.

The European Cultural Heritage Strategy for the 21st century has led to an increased demand for fast, efficient and faithful 3D digitization technologies for cultural heritage artefacts. Yet, unlike the digital acquisition of cultural goods in 2D which is widely used and automated today, 3D digitization often still requires significant manual intervention, time and money. To overcome this, the authors have developed CultLab3D, the world's first fully automatic 3D mass digitization technology for collections of three-dimensional objects. 3D scanning robots such as the CultArm3D-P are specifically designed to automate the entire 3D digitization process thus allowing to capture and archive objects on a large-scale and produce highly accurate photo-realistic representations.

Full textAbstract:
As 3D digitization becomes more common in collections documentation and research, there is a growing need for tools which address the special needs of 3D data stewardship. Systems are needed to manage both the scan data collected during digitization activities, as well as the 3D models generated from that data. These systems need to be able to preserve and make transparent the complex relationships inherent in the data created from 3D digitization activities. They need to connect digital surrogates back to the objects they represent as well as provide an easy way to discover and retrieve that data for research, conservation, and public access. At the core of such systems there needs to be metadata models that can account for the intricacies and specific needs of managing 3D data. This year, the Smithsonian Institution will be deploying new infrastructure which does just that, based on a metadata model developed by a cross disciplinary working group comprised of content experts from across the institution. The platform, which not only manages scan data, but also automates the processing and delivery of 3D digitized content, is open source and is built around modular design principles for easier adoption. This talk builds upon last year's SPNHC presentation "Automating 3D collection capture: Developing systems for 3D digitization at scale" as it addresses the information systems and infrastructure needed to support the management and delivery of 3D data at scale. We will cover the basic functionality of the Smithsonian's 3D data repository, how it facilitates data administration, the workflows involved in managing and processing data, and how it connects to the larger Smithsonian infrastructure. As part of this, we will explore the metadata model behind the system and how the model can support greater usability and transparency when sharing and working with 3D scan data.

Modern digitization technologies have created an increasing number of possibilities for capturing the physical dimensions and appearance of archaeological artifacts and sites in 3D. The usage of such data is usually targeted to the research, study, and documentation of our cultural heritage. At the same time, the increasing quality of the produced digitizations has opened new possibilities for the further exploitation of digitization outcomes in a wider context than initially expected. A pioneer in this direction was the gaming industry, where photogrammetry has been recently employed to achieve extreme photorealism. Of course, challenges still exist, especially when digitization accuracy is of importance, such as in the case of large-scale archaeological sites. Further challenges regard the need to combine indoor and outdoor scenes that pose requirements in the selection of the appropriate digitization modalities and post-processing strategies. In more detail, the challenges relate to the appropriate usage of existing technologies, organization issues in terms of digitization visits, the combination and registration of data, data acquisition, and data processing methodologies, etc. In this paper, we demonstrated a methodology for the digitization of archaeological sites that can be used for creating digital assets suitable for various scenarios including research, education, and entertainment.

Full textAbstract:
In the field of digital cultural heritage (DCH), 2D/3D digitization strategies are becoming more and more complex. The emerging trend of multimodal imaging (i.e., data acquisition campaigns aiming to put in cooperation multi-sensor, multi-scale, multi-band and/or multi-epochs concurrently) implies several challenges in term of data provenance, data fusion and data analysis. Making the assumption that the current usability of multi-source 3D models could be more meaningful than millions of aggregated points, this work explores a “reduce to understand” approach to increase the interpretative value of multimodal point clouds. Starting from several years of accumulated digitizations on a single use-case, we define a method based on density estimation to compute a Multimodal Enhancement Fusion Index (MEFI) revealing the intricate modality layers behind the 3D coordinates. Seamlessly stored into point cloud attributes, MEFI is able to be expressed as a heat-map if the underlying data are rather isolated and sparse or redundant and dense. Beyond the colour-coded quantitative features, a semantic layer is added to provide qualitative information from the data sources. Based on a versatile descriptive metadata schema (MEMoS), the 3D model resulting from the data fusion could therefore be semantically enriched by incorporating all the information concerning its digitization history. A customized 3D viewer is presented to explore this enhanced multimodal representation as a starting point for further 3D-based investigations.

The results of the measured values and findings serve as useful information when deciding on the choice of 3D digitization method for measuring seamless steel tubes.

History<br>M.A.<br>This project draws upon material culture, digital humanities, and archival theory and method in the service of public history investigations. After selecting an artifact and performing object analysis, I will digitize the artifact and materialize a new object. I will then perform another object analysis on the 3D printed object. This exercise will provide the familiar benefits of object analysis, but the decisions and interactions necessary to digitize and materialize the object provide a fresh perspective. I will propose approaches for performing similar investigations in repositories, along with a pedagogical argument for doing so. By emphasizing modularity, flexibility, and minimal capital requirements, I hope these approaches can be adapted to a variety of institutions and audiences. Researchers will reap the benefits of intellectual and emotional engagement, hands-on learning, and technological experimentation. Public historians will have the opportunity to engage in outreach and innovative education and exploration of their collections.<br>Temple University--Theses

The technical paper deals with the application of 3D scanning for the preparation of cast machining which is a part of steam turbines manufactured by the Industrial Turbo machinery branch office of the Siemens Ltd. in Brno. There is a theoretic explanation of general terms which relate to the 3D digitization process in the first part. Further in the theoretic part, the used digitization systems TRITOP and ATOS are described in detail. In practical part, the analysis of the current process has been carried out and the alternate process of the cast preparation for a subsequent machining has been suggested. By means of above mentioned systems, the cast has been converted in a digital form and compared with the source CAD module. The comparison results in material allowance check and the suitable setting for a following machining process. In conclusion, the technical economic evaluation of both processes has been carried out.

Full textAbstract:
Plumage is a stereoscopic 3D experience showcasing the culmination of a personal exploration and observation of birds: a digitally modeled and rendered, fantastical bird referred to simply as a Phoenix. In many cultures birds are tied to ideas of freedom, power, and the otherworldly. Preconceived notions of a phoenix exist across many cultures as well, but for this project I wanted to create my own interpretation.
While working, I drew upon my admiration of birds for their qualities of strength, beauty, and curiosity to infuse into the project. Inspired by the dynamic and detailed works of naturalists like John James Audubon, I took the opportunity to make my own observations and records of birds.
I began exploring different processes of digitizing three-dimensional forms by scanning bird skins. However, due to the nature of fibrous and reflective materials (of which birds are often both) I ran into challenges that made accurate and detailed representation difficult if not impossible. From there I made the decision to pursue a more imaginative artistic approach to the project.
More than just a homage to feathers and birds, this project represents the continued value of artists in the field of preservation and their ability to push visuals further with their own observations where automation and digitization fall short. Using life references I created my own textures and forms with details meant to emulate my favorite aspects of the birds that inspired me throughout my journey.
Larger-than-life, projected stereoscopic 3D allows the audience to see details clearly and enhances the dynamic quality of the piece; both very important elements that needed to shine through in the final artwork. Plumage is made possible through the use of the Cyclorama, a series of convex screens that surround an audience and allow them to appreciate scenes projected in stereoscopic 3D.<br>Master of Fine Arts

Full textAbstract:
Die Idealvorstellung eines vollständig digitalisierten Behandlungsalltags rückt mit fortschreitender technologischer und informationeller Entwicklung stetig näher an die Realität. Zu Beginn bestand lediglich die Möglichkeit einer elektronischen Patientenakte, hinzu kamen vielfältige Möglichkeiten der digitalen Bildgebung und wurden schließlich um das Ziel eines vollständigen digitalen Workflows ergänzt. Die Planung der interdisziplinären kieferorthopädischen / kieferchirurgischen Versorgung von Patienten mit Lippen-Kiefer-Gaumen-Spalten (LKGS) wurde bis vor kurzem am Universitätsklinikum Dresden noch hauptsächlich analog durchgeführt. Eine volldigitalisierte Behandlungsplanung unter Einbeziehung aller beteiligten Behandler fand nicht statt. Ziel des Projektes war es deshalb, eine digitale Plattform zur interdisziplinären zahnmedizinischen Versorgung von LKGS-Patienten zu schaffen. Dazu wurde zuerst die bisher erforderliche Abdrucknahme mittels Alginat und die anschließende Herstellung eines Gipsmodells durch einen intraoralen 3D-Scan der Zahnbögen des Patienten abgelöst. Anhand des intraoralen 3D-Scans können nun die erforderlichen Trinkplatten mittels 3D-Druck erstellt werden. Zweiter Schritt war die Anfertigung von 3D-Aufnahmen der Weichteile des Gesichtes mittels eines extraoralen 3D-Scanners. Als dritter Schritt erfolgte die Anfertigung von Digitalen Volumentomografie (DVT)-Aufnahmen zur 3D-Darstellung des Schädelknochens und Kieferskeletts. Nach der Anfertigung wurden diese bildbasierten Datensätze zu einem „digitalen Zwilling“ (virtuelles 3D-Modell aus DVT, intra- und extraoralen 3D-Scan) zusammengefasst, wodurch erstmalig ein umfassendes 3D-Modell des Mund-Kiefer-Raumes einschließlich wichtiger Informationen zum Kiefergelenk und der anliegenden Weichteile entstand. Dieses virtuelle Modell bildet jetzt die Grundlage für die Behandlungsplanung und die Planung der weiteren zahnmedizinischen und medizinischen Versorgung. Es konnte also im Projekt die komplette Digitalisierung der Diagnostik, die Etablierung einer Fusionsplattform und der Datenaustausch zwischen Uniklinik und privater Praxis umgesetzt werden.

Full textAbstract:
A surface characterisation of the Arnager Greensand in south Sweden, a deep saline aquifer found to be suitable for geological storage of CO2 or energy storage, was undertaken in this thesis. Vintage seismic reflection data only available as scanned tiff images of the final stacked sections were digitized and processed using modern interpretation software to provide new insights into the morphology of the Arnager Greensand and to analyse the reservoir’s potential as an energy storage unit. The primary energy storage method discussed and evaluated was Compressed Air Energy Storage (CAES). This is a modern energy storage method developed as a tool for regulating inherently intermittent renewable energy sources. Such methods are key to the growth of the renewable sector and for providing a competitive alternative to fossil fuels. Moreover, in comparison with other energy storage methods such as battery storage, CAES is known to have strong potential to deliver highperformance energy storage at large scales for relatively low costs compared with any other solution. Previous studies conducted in the 1980’s by Swedegas produced a 2D isochrone surface map of the Arnager Greensand by hand interpolation methods utilizing analogue data collected by Oljeprospektering AB (OPAB, currently Svenska Petroleum). The Geological Survey of Sweden (SGU) has now transferred a vast amount of the historical OPAB dataset to modern digital format. This thesis contributes to those efforts and seeks to find new interpretations from the vintage data. A more comprehensive 3D model of the top of the Arnager Greensand employing the application of modern interpretation software was produced in this study. Strong similarities between morphology and dip-trend have been observed between the surface model generated in this report and the historical Swedegas isochrone surface map. Reservoir properties such as thickness, porosity and permeability gleaned from the earlier reports show the Arnager Greensand to exhibit excellent potential as a storage unit. Preliminary effective capacity estimates by Nordic CCS Competence centre show the Aranger Greensand to be one of the top three storage aquifers in Sweden. These positive appraisals highlight the need for a better characterization of the Aranger Greensand through data digitization and modern interpretation means. This thesis contributes to that endeavour.

Entende-se que ao assumir uma atitude faça-você-mesmo, bem como táticas de apropriação e princípios maker, é possível uma aproximação e maior interação dos museus com a sociedade contemporânea, podendo oferecer uma renovação participativa e contínua de processos. Isto tudo, sem demandar grandes investimentos, motivando os participantes a aprender fazendo e a compartilhar o conhecimento. O uso de uma técnica de digitalização tridimensional faça-você-mesmo, além de trazer agregada a atitude, possibilita a valorização do acervo museológico. Um objeto da coleção torna-se, então, capaz de transpor sua singularidade para alcançar distâncias além das geográficas, levando para o público seu conhecimento para valorização e conscientização de salvaguardar o acervo. Neste sentido, esta pesquisa contempla o desafio de propor diretrizes projetuais para o uso da digitalização 3D faça-você-mesmo em diferentes tipologias de acervos museológicos. Essas diretrizes foram construídas a partir de informações levantadas em experimentos e entrevistas, posteriormente, trabalhadas através de um processo criativo realizado num workshop no Museu Júlio de Castilhos, instituição museológica mais antiga do Rio Grande do Sul, e, por fim, diretrizes e resultados do workshop passam por um refinamento para a confecção de um framework de diretrizes projetuais. O perfil da instituição participante das atividades da pesquisa foi estabelecido por sua variedade de coleção, por apresentar peças com diferentes características físicas, químicas e morfológicas. Os resultados obtidos indicaram a oportunidade de tornar o acervo do museu mais acessível ao público de forma segura, possibilitando diferentes atividades educativas, maior disponibilidade, alcance para as pesquisas e maior conhecimento do acervo do museu.<br>It is understood that by taking a do-it-yourself attitude, as well as appropriation tactics and maker principles, it is possible to approach and interact more museums with contemporary society and can offer a participatory and continuous renewal of processes. All this, without demanding large investments, motivating participants to learn by doing and sharing knowledge. The use of a three-dimensional digitization technique do-it-yourself, in addition to bringing aggregates to the attitude, makes possible the valuation of the museological collection. An object of the collection becomes able to transpose its singularity to reach distances beyond the geographic ones, taking to the public its knowledge for valuation and awareness to safeguard these collections. In this sense, this research contemplates the challenge of proposing design guidelines for the use of do-it-yourself 3D digitization to be used in different types of museums. These guidelines were constructed from information collected in experiments and interviews, later worked through a creative process carried out in a workshop at the Júlio de Castilhos Museum, the oldest museum in Rio Grande do Sul, and, finally, guidelines and results of the workshop will go through a refinement for the creation of a framework of design guidelines. The profile of the institution participating in the research activities was established by its collection variety, because it presents pieces with different physical, chemical and morphological characteristics. The results indicated the opportunity to make the museum's collection more accessible to the public in a safe way, allowing different educational activities, greater availability, scope for research and greater knowledge of the museum's collection.

Full textAbstract:
Syfte: Den digitala utvecklingen inom byggproduktionssektorn ligger efter jämfört med många andra branscher och har fått ryktet om att vara rent av konservativ. Att säga att utvecklingen står stilla stämmer inte då majoriteten av företagen arbetar aktivt för en mer digitaliserad sektor. Trots detta domineras produktionsplatserna av pappersdokument, icke autonoma system och själva arbetet utförs mer eller mindre på samma sätt som det gjort i flera decennier. Trots att flertalet digitala verktyg och implementeringsmodeller finns tillgängliga möter dem inom byggproduktionssektorn en hel del motstånd. Denna rapport granskar de digitala innovationer som är på uppgång och som kan göra betydande nytta inom byggproduktion. Metod: Via sökmotorer på högskolans databas, samt internet gjordes insamling av rådata som sedan skulle analyseras och ligga till grund för kvalitativ insamlingsmetod. Litteraturstudien var grundpelaren som betingade de semistrukturerade intervjuerna, som i sin tur möjliggjorde en jämförelse mellan det teoretiska ramverket och intervjuresultat. Resultat: En klar majoriteten av de intervjuade aktörerna ansåg att 3D-skrivaren någon gång i framtiden kommer att inta byggsektorn. En implementering av 3D-skrivaren skulle medföra kortare produktionstider, reducerade produktionskostnader, eliminering av spill och mindre arbetskostnader. Autonoma systems inträde i byggproduktionssektorn kommer förmodligen inte ske inom en snar framtid då olika byggprojekt skiljer sig åt väldigt mycket. Hade byggandet blivit mer monotont skulle det underlätta väldigt mycket, men i dagsläget är sällan ett projekt det andra likt. Big data är en innovation som skulle kunna revolutionera byggbranschen på flera håll. Respondenterna förstod dock inte begreppets innebörd vilket tyder på att det inte satsas någonting på Big data inom produktionssektorn. Möjligheterna för Big data är många och det kan bland annat användas för effektivare kommunikation, effektivisering av produktionsplatsen, mer detaljerad koll på olika maskiner och mer kontrollerade material leveranser. Konsekvenser: För en allmänt lyckad implementering av 3D-skrivaren krävs det att även de mindre företagen kan införskaffa apparaten. De större företagen riskerar annars att konkurrera ut de mindre företagen. Då betong i allmänhet är ett material med förhållandevis hög miljöpåverkan medför detta konsekvenser för miljön som redan befinner sig i en utsatt position. Då det arbetas väldigt aktivt med att förbättra omvärldens miljöpåverkan är det därför viktigt att lägga fokus på att försöka producera mer miljövänlig betong. Begränsningar: Studien begränsades till ett fåtal svenska byggföretag i göteborgsregionen. I rapporten tas därför endast de fåtal respondenters åsikter med.<br>Purpose: The digital progress is slow within the constructional sector in comparison to other type of businesses and it has the reputation of being relatively conservative. To say that the progress is standing still would be mistake since the majority of constructional companies are working actively for a more digital construction site. Even though these companies are working hard towards a more digital sector the construction site is dominated by paper documents, non-autonomic systems and the labor is done the same way as it has been done for decades. Even though multiple digital tools and implementation models are available the construction sector is facing a lot of resistance. This report examines those digital innovations that are on the rampaging and can do a significant good within the construction sector. Method: Through search engines at the university's database, as well as the internet, collection of raw data was collected, which would then be analyzed and underlie for qualitative collection methods. The literature study was the foundation of the semistructured interviews, which in turn enabled a comparison between the theoretical framework and interview results. Findings: A vast majority of the interviewed participants believe that the 3D-printer sometime in the future may be used within the construction sector. An implementation of the 3D-printer would induce shorter production times, reduced production costs, elimination of waste and reduced costs for labor. Autonomic systems will probably not be implemented on construction sites within a short future since different construction projects are to diverse. If the construction would become more monotonic it would ease considerably, but today one project is rarely analogous to the other. Big data is an innovation that could revolutionize the construction sector in a lot of different ways. The respondents did not understand the meaning of the term, which interpret that it is not an innovation in focus for the time being. The possibilities of Big data are substantial and it could be used for more effective communication, more efficiency within the construction site, more detailed checkups of machinery and more controlled building material checkups. Implications: For a generally successful implementation of 3D-printers they need to be affordable for the smaller companies. Otherwise the larger firms risk to put the smaller firms out of business. Since concrete is a material with a relatively large impact on the environment this may cause consequences for the environment in the future since its already in an exposed situation. Since it´s globally working actively with improving the environment the focus should be in producing more environmentally acceptable concrete for the 31d-printers. Limitations: The study was limited to a handful of Swedish constructional companies within the Gothenburg region. In the report, only the opinions of a few respondent are taken to consideration.

Full textAbstract:
Das Potenzial, welches der 3D-Druck im Tissue Engineering für Weichteilgewebe und Knochenersatz hinsichtlich Formgebung und Materialanpassung bietet, wird zunehmend genutzt, weiterentwickelt und ausgebaut. Die Diversität der dabei betrachteten, biologisch aktiven Biomaterialien setzt voraus, dass unterschiedliche Technologien wie Stereolithographie (STL), Fused Deposition Modelling (FDM), Selektives Lasersintern (SLS) in verschiedenen Ausbaustufen zum Einsatz kommen. In medizinischen Anwendungen und besonders im pharmazeutischen Bereich, sind neben den drei räumlichen Dimensionen zusätzlich weitere Dimensionen hinsichtlich der Produkteigenschaften interessant. Einerseits besteht diese Mehrdimensionalität aus strukturellen und geometrischen Gradienten (An, Teoh, Suntornnond & Chua, 2015; Jones et al., 2007; Neri Oxman, Steven Keating & Elizabeth Tsai, 2012). Zusätzlich sind aber auch stoffliche Abstufungen der prozentualen Anteile wichtig. Das betrifft beispielsweise die Einbringung von Wirkstoffen in die generativ aufgebauten Strukturen (Goole & Amighi, 2016; Kalaskar, 2017; Ursan, Chiu & Pierce, 2013). Meist werden dabei scharf abgegrenzte Abstufungen der Materialeigenschaften gezeigt. Dies erfolgt im 3D-Druck beispielsweise durch die Nutzung unterschiedlicher Dosierköpfe in einem Prozess für die jeweiligen Materialien/Materialabstufungen oder durch die getrennte Herstellung der einzelnen Bereiche und anschließendem Fügen der Scaffolds (Diaz-Gomez et al., 2019). Ein allmählich ansteigender/abflachender gradueller Verlauf des zugemischten Anteils (Wirkstoff/Marker) wird bisher nicht beschrieben. Gelingt eine Regelung der Wirkstoffzumischung während des generativen Prozesses, entstehen neue Freiheitsgrade in der Gestaltung der Eigenschaften, wie beispielsweise der pharmazeutischen Wirksamkeit der Produkte. Im biomedizinischen Kontext sind durch Gradientengestaltung innerhalb eines Implantates, unterschiedliche Wirkstoffkonzentrationen oder funktionelle Parameter, wie Festigkeit, Verformbarkeit oder Reaktivität einstellbar. Bei der Zumischung innerhalb des 3D-Drucks ist auch der Einsatz solcher Wirkstoffe denkbar, die bei konventionellen Herstellungsprozessen herausgelöst oder zersetzt würden. Innerhalb der interdisziplinären Zusammenarbeit zwischen der Pharmazeutischen Technologie (Institut für Pharmazie, Medizinische Fakultät) der Universität Leipzig und der Fakultät Maschinenbau und Energietechnik (Maschinenbautechnisches Institut) an der HTWK Leipzig wurde ein miniaturisierter Doppelschneckenextruder (DSE-DK) als Dosierkopf in eine 3D-Druckanlage integriert. Mit der auf dem FDM-Verfahren basierenden Technologie konnte bereits nachgewiesen werden, dass Polymere wie Polycaprolacton (PCL) verarbeitet und mit zugemischten Pulvern homogenisiert werden können (Flath et al., 2016). Es wurden innerhalb eines 3D-Druckprozesses Materialmischungen aus einer aufgeschmolzenen Polymerphase und einem zugeführten Pulver erzeugt. In diesem Aufbau konnten alle Materialien als Pulver zugeführt und dosiert werden. Ziel der hier betrachteten Arbeiten war es, den DSE-DK für pastöse Ausgangsstoffe zur Erweiterung des Einsatzspektrums nutzbar zu machen. Zusätzlich sollten Pasten/Pulver Mischungen und die Möglichkeit der Herstellung von graduellen Zusatzstoffkonzentrationen während der dreidimensionalen Verarbeitung untersucht werden.

Full textAbstract:
AbstractComplexity and data quality of a project are strongly linked together. The higher the need for better data quality is, the more complex projects become. In digitization, various complexity factors have an impact on the quality, such as the object properties or environmental factors. However, it also largely depends on the employed technology. Digitization instruments are designed for specific purposes and applications and have defined specifications and limitations. Some devices perform better with one material or another, and can capture invisible detail or geometry at large distance.The aim of a holistic documentation often implies to take into account significant amount of additional data and of different nature. Equipping devices with multiple sensors, allows capturing more information and detail at the same time, which means a massive increase of data - intensifying the challenge. Thus, it is mandatory to be aware of the strengths and limitations to decide which technology, or a combination thereof, fits best for each case.Smart technological ideas and sensor design can mitigate the complexity. At the example of terrestrial 3D laserscanners by Zoller + Fröhlich, this article provides insight to manufacturer’s strategies about ensuring maximum survey quality and proposing efficient solutions for complexity reduction in survey projects. The technological answers range from sensorial adaptions to sophisticated workflow approaches and the incremental use of intelligent algorithms to an outlook on the necessary focus for the future. The approaches are illustrated with examples from emblematic use cases of outstanding tangible Heritage digitization in Europe.

AbstractThe article explores the impact of transitioning an Egyptian s$$\bar{a}$$ a ¯ qia, a traditional water-lifting device, from 2D blueprints to a comprehensive 3D model, offering new insights into historical artifacts. Despite financial challenges hindering the digitization of African archaeological hydraulic structures, the research emphasizes the importance of embracing 3D reconstructions. The 3D model reveals the intricate engineering complexities and cultural significance of ancient hydraulic systems through data collection and processing techniques. Strategic decision-making in data analysis is crucial, with broader implications highlighted. The article advocates for increased support for 3D digitization initiatives in African archaeology, recognizing their transformative potential in preserving cultural heritage. By addressing financial obstacles, 3D reconstructions offer more than mere data acquisition, extending to strategic considerations of paradata. These efforts enrich the global understanding of African history and technological advancements. Investing in 3D digitization is essential for preserving cultural heritage and advancing knowledge of African contributions to human civilization.

Full textAbstract:
Civil infrastructure is prone to deterioration due to several factors like loading and environmental agents. Condition assessment of these infrastructures is done on a visualization basis by the field inspector. The data collected by the inspector is biased and depends on the perception, experience, and visuals of the inspector. The data collected in terms of images and characteristics of the deterioration is recorded on a qualitative basis in the data log. The report is then presented to the managers or decision-makers to make decisions on the maintenance of the facility. In this era, various sensing and visualization technologies are available that can be utilized to create a digitized as-built model in 3D with exact dimensions and deteriorations, also known as a 3D re-constructed model. In this research, a 3D reconstructed model of an elevated overhead water tank has been created using laser scanning, UAV (Unmanned aerial vehicle). Artificial intelligence has been used to detect and measure cracks or openings on the surface of the structure. Deflection and rotation of the elements of the structure have been quantified by superimposing the point cloud model over the as-planned model in the interface of Navisworks.

Full textAbstract:
Ground Penetrating Radars (GPR) finds its applications in civil engineering, archeology, earth sciences, military and environmental studies. This paper proposes a framework for using GPR as a digitizing technique that can make 3D digitization/measurement of the buried objects. Currently, the 3D radar volume data is acquired by dense subset of parallel 2D radar profiles. However, it results in a very large amount data and related processing time, and needs to be avoided due to the significant computer resources and processing time required to process the data. In order to achieve simplified and faster processing as well as to reduce memory requirements, it is often useful to convert the original image data to a more compact representation. The conversion removes as much of the redundant information as possible. Then the data is processed by removing noise initially and then eliminating undesired presence of ground surface echo. Further, propagation losses are compensated followed by segmentation and skeletonizing. However the accuracy of the 3D measurement depends upon number of parameters such as antenna design, scan paths, scan spacing and frequency which needs to be evaluated in detail. The framework presented in this paper would help to measure the buried objects accurately using 3D GPR.
