Towards 3D Digitization in the GLAM (Galleries, Libraries, Archives, and Museums) Sector – Lessons Learned and Future Outlook

The IPSI BgD Transactions on Internet Research

The European Cultural Heritage Strategy for the 21st century, within the Digital Agenda, one of the flagship initiatives of the Europe 2020 Strategy, has led to an increased demand for fast, efficient and faithful 3D digitization technologies for cultural heritage artefacts. 3D digitization has proven to be a promising approach to enable precise reconstructions of objects. 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 enable heritage institutions to make use of large scale, economic, and automated 3D digitization technologies, the Competence Center for Cultural Heritage Digitization at the Fraunhofer Institute for Computer Graphics Research IGD has 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. The unique setup allows to shorten the time needed for digitization from several hours to several minutes per artefact.

Planning exhibitions of cultural artifacts is always challenging. Artifacts can be very sensitive to the environment and therefore their display can be risky. One way to circumvent this is to build replicas of these artifacts. Here, 3D digitization and reproduction, either physical via 3D printing or virtual, using computer graphics, can be the method of choice. For this use case we present a workflow, from photogrammetric acquisition in challenging environments to representation of the acquired 3D models in different ways, such as online visualization and color 3D printed replicas. This work can also be seen as a first step towards establishing a workflow for full color end-to-end reproduction of artifacts. Our workflow was applied on cultural artifacts found around the “Roseninsel” (Rose Island), an island in Lake Starnberg (Bavaria), in collaboration with the Bavarian State Archaeological Collection in Munich. We demonstrate the results of the end-to-end reproduction workflow leading to virtual replicas (online 3D visualization, virtual and augmented reality) and physical replicas (3D printed objects). In addition, we discuss potential optimizations and briefly present an improved state-of-the-art 3D digitization system for fully autonomous acquisition of geometry and colors of cultural heritage objects.

Photometric multi-view 3D geometry reconstruction and material capture are important techniques for cultural heritage digitalization. Capturing images of artifacts with high resolution and high dynamic range and the possibility to store them losslessly enables future proof application of this data. As the images tend to consume immense amounts of storage, compression is essential for long time archiving. In this paper, we present a lossless image compression approach for multi-view and material reconstruction datasets with a strong focus on data created from cultural heritage digitalization. Our approach achieves compression rates of 2:1 compared against an uncompressed representation and 1.24:1 when compared against Gzip.

We show how to overcome the single weakness of an existing fully automatic system for acquisition of spatially varying optical material behavior of real object surfaces. While the expression of spatially varying material behavior with spherical dependence on incoming light as a 4D texture (an ABTF material model) allows flexible mapping onto arbitrary 3D geometry, with photo-realistic rendering and interaction in real time, this very method of texture-like representation exposes it to common problems of texturing, striking in two disadvantages. Firstly, non-seamless textures create visible artifacts at boundaries. Secondly, even a perfectly seamless texture causes repetition artifacts due to their organised placement in large numbers over a 3D surface. We have solved both problems through our novel texture synthesis method that generates a set of seamless texture variations randomly distributed over the surface at shading time. When compared to regular 2D textures, the inter-dimensional coherence of the 4D ABTF material model poses entirely new challenges to texture synthesis, which includes maintaining the consistency of material behavior throughout the 4D space spanned by the spatial image domain and the angular illumination hemisphere. In addition, we tackle the increased memory consumption caused by the numerous variations through a fitting scheme specifically designed to reconstruct the most prominent effects captured in the material model.

We created a fully automatic system for acquisition of spatially varying optical material behavior of real object surfaces under a hemisphere of individual incident light directions. The resulting measured material model is flexibly applicable to arbitrary 3D model geometries, can be photorealistically rendered and interacted with in real-time and is not constrained to isotropic materials.

3D scanning and 3D printing are two rapidly evolving domains, both generating results with a huge and growing spectrumof applications. Especially in Cultural Heritage, a massive and increasing amount of objects awaits digitization for variouspurposes, one of them being replication. Yet, current approaches to optical 3D digitization are semi-automatic at best andrequire great user effort whenever high quality is desired. With our solution we provide the missing link between both domains,and present a fully automatic 3D object replicator which does not require user interaction. The system consists of ourphotogrammetric 3D scanner CultArc3D_mini that captures an optimal image set for 3D geometry and texture reconstructionand even optical material properties of objects in only minutes, a conveyor system for automatic object feed-in and -out,a 3D printer, and our sensor-based process flow software that handles every single process step of the complex sequencefrom image acquisition, sensor-based object transportation, 3D reconstruction involving different kinds of calibrations, to3D printing of the resulting virtual replica immediately after 3D reconstruction. Typically, one-button machines require theuser to start the process by interacting over a user interface. Since positioning and pickup of objects is automatically registered,the only thing left for the user to do is placing an object at the entry and retrieving it from the exit after scanning. Shortly after,the 3D replica can be picked up from the 3D printer. Technically, we created a zero-button 3D replicator that provides highthroughput digitization in 3D, requiring only minutes per object, and it is publicly showcased in action at 3IT Berlin.

We have lifted the one weakness of an existing fully automatic acquisition system for spatially varying optical material behavior of real object surfaces. While its expression of spatially varying material behavior with spherical dependence on incoming light as 4D texture (ABTF material model) allows flexible mapping on arbitrary 3D geometries, photo-realistic rendering and interaction in real-time, this very method of texture-like representation exposed it to common problems of texturing, striking in two levels. First, non-seamless textures create visible border artifacts. Second, even a perfectly seamless texture causes repetition artifacts due to side-by-side distribution in large numbers over the 3D surface. We solved both problems through our novel texture synthesis that generates a set of seamless texture variations randomly distributed on the surface at shading time. When compared to regular 2D textures, the inter-dimensional coherence of the 4D ABTF material model poses entirely new challenges to texture synthesis, which includes maintaining the consistency of material behavior throughout the space spanned by the spatial image domain and the angular illumination hemisphere. In addition, we tackle the increased memory consumption caused by the numerous variations through a fitting scheme specifically designed to reconstruct the most prominent effects captured in the material model.

Acceleration of 3D Mass Digitization Processes: Recent Advances and Challenges

Mixed Reality and Gamification for Cultural Heritage

In the heritage field, the demand for fast and efficient 3D digitization technologies for historic remains is increasing. Besides, 3D has proven to be a promising approach to enable precise reconstructions of cultural heritage objects. Even though 3D technologies and postprocessing tools are widespread and approaches to semantic enrichment and Storage of 3D models are just emerging, only few approaches enable mass capture and computation of 3D virtual models from zoological and archeological findings. To illustrate how future 3D mass digitization systems may look like, we introduce CultLab3D, a recent approach to 3D mass digitization, annotation, and archival storage by the Competence Center for Cultural Heritage Digitization at the Fraunhofer Institute for Computer Graphics Research IGD. CultLab3D can be regarded as one of the first feasible approaches worldwide to enable fast, efficient, and cost-effective 3D digitization. lt specifically designed to automate the entire process and thus allows to scan and archive large amounts of heritage objects for documentation and preservation in the best possible quality, taking advantage of integrated 30 visualization and annotation within regular Web browsers using technologies such as WebGI and X3D.

With projects such as CultLab3D, 3D Digital preservation of cultural heritage will become more affordable and with this, the number of 3D-models representing scanned artefacts will dramatically increase. However, once mass digitization is possible, the subsequent bottleneck to overcome is the annotation of cultural heritage artefacts with provenance data. Current annotation tools are mostly based on textual input, eventually being able to link an artefact to documents, pictures, videos and only some tools already support 3D models. Therefore, we envisage the need to aid curators by allowing for fast, web-based, semi-automatic, 3D-centered annotation of artefacts with metadata. In this paper we give an overview of various technologies we are currently developing to address this issue. On one hand we want to store 3D models with similarity descriptors which are applicable independently of different 3D model quality levels of the same artefact. The goal is to retrieve and suggest to the curator metadata of already annotated similar artefacts for a new artefact to be annotated, so he can eventually reuse and adapt it to the current case. In addition we describe our web-based, 3D-centered annotation tool with meta- and object repositories supporting various databases and ontologies such as CIDOC-CRM.

We introduce c-Space, an approach to automated 4D reconstruction of dynamic real world scenes, represented as time-evolving 3D geometry streams, available to everyone. Our novel technique solves the problem of fusing all sources, asynchronously captured from multiple heterogeneous mobile devices around a dynamic scene at a real word location. To this end all captured input is broken down into a massive unordered frame set, sorting the frames along a common time axis, and finally discretizing the ordered frame set into a time-sequence of frame subsets, each subject to photogrammetric 3D reconstruction. The result is a time line of 3D models, each representing a snapshot of the scene evolution in 3D at a specific point in time. Just like a movie is a concatenation of time-discrete frames, representing the evolution of a scene in 2D, the 4D frames reconstructed by c-Space line up to form the captured and dynamically changing 3D geometry of an event over time, thus enabling the user to interact with it in the very same way as with a static 3D model. We do image analysis to automatically maximize the quality of results in the presence of challenging, heterogeneous and asynchronous input sources exhibiting a wide quality spectrum. In addition we show how this technique can be integrated as a 4D reconstruction web service module, available to mobile end-users.

Um dem wachsenden Bedarf nach optimierten Scanverfahren in 3D im Kulturbereich zu entsprechen, entwickelt das Fraunhofer Institut für Graphische Datenverarbeitung IGD einen Ansatz zur 3D-Massendigitalisierung. Um Objektmengen effizient zu erfassen, wird die bisher zeit- und kostenintensive Datenakquise durch Automatisierung des Prozessablaufs beschleunigt. Zudem wird eine originalgetreue Wiedergabe in hoher Qualität angestrebt, die Geometrie, Textur und optische Materialeigenschaften berücksichtigt.

Journal of Cultural Heritage

Complete and detailed 3D-scanning of cultural heritage artifacts is a still time-consuming process that requires skilled operators. Automating the digitization process is necessary to deal with the growing amount of artifacts available. It poses a challenging task because of the uniqueness and variety in size, shape and texture of these artifacts. Scanning devices have usually a limited focus or measurement volume and thus require precise positioning. We propose a robotic system for automated photogrammetric 3D-reconstruction. It consists of a lightweight robotic arm with a mounted camera and a turntable for the artifact. In a virtual 3D-environment, all relevant parts of the system are modeled and monitored. Here, camera views in position and orientation can be planned with respect to the depth of field of the camera, the size of the object and preferred coverage density. Given a desired view, solving inverse kinematics allows for collision-free and stable optimization of joint configurations and turntable rotation. We adopt the closed-loop inverse kinematics (CLIK) algorithm to solve the inverse kinematics on the basis of a particular definition of the orientation error. The design and parameters of the solver are described involving the option to shift the weighting between different parts of the objective function, such as precision or mechanical stability. We then use these kinematic solutions to perform the actual scanning of real objects. We conduct several tests with different kinds of objects showing reliable and sufficient results in positioning and safety. We present a visual comparison involving the real robotic system with its virtual environment demonstrating how view poses for different-sized objects are successfully planned, achieved and used for 3D-reconstruction.

Museumskunde

Seit mehr als einem Jahrzehnt gibt es umfangreiche Maßnahmen zur digitalen Verarbeitung und Visualisierung von Sammlungsbeständen. So sind die EU-Mitgliedstaaten noch Empfehlungen der Europäischen Kommission im Rahmen der Digitalen Agenda aufgefordert, Digitalisierung, Online-Verfügbarkeit und digitale Erhaltung von historischem Material voranzutreiben. Auch die Reflexionsgruppe zur "Digitalisierung des kulturellen Erbes in Europa" erwartet unter Hinweis auf dessen wirtschaftliches Potenzial eine "neue Renaissance" durch Zusammenführung von Beständen im Netz. Während vor diesem Hintergrund die digitale Aufbereitung von Kulturgut in 2D längst zur Kernaufgabe von Bibliotheken, Archiven und Museen gehört, ist die 3D-Digitalisierung von dreidimensionalen Artefakten aufgrund ihrer komplexeren Form noch immer eine Herausforderung. Aufgrund des hohen Kosten- und Zeitaufwands konzentrieren sich hier Maßnahmen auf prestigeträchtige Einzelobjekte statt auf ganze Sammlungen. Denn es existieren bisher keine kommerziell verfügbaren Technologien zur effizienten und hochpräzisen Massendigitalisierung in 3D. Auch bleibt die 3D-Digitalisierung in den wenigen existenten Digitalisierungs- und Erhaltungsstrategien von musealen Einrichtungen noch immer unberücksichtigt. Erst jüngst wurden die DFG-Praxisregeln zur Digitalisierung dahingehend überarbeitet, unter dem Begriff nicht mehr ausschließlich die digitale Fotografie zu verstehen. In der aktualisierten Version wird zwischen der digitalen Repräsentation eines dreidimensionalen Objekts und dessen digitaler Replik unterschieden. Ersteres stellt eine ,,fotografische Erfassung aller relevanten visuellen Eigenschaften des Objekts, meist von mehr als einem Aufnahmestandpunkt" dar. Eine digitale Replik hingegen ist eine "originalgetreue Rekonstruktion seiner Form und Oberflächen-Licht-lnteraktion", also ein digitales 3D-Modell samt Hülle und Anmutung.

In addition we describe our web-based, 3D-centered annotation tool with meta- and object repositories supporting various databases and ontologies such as CIDOC-CRM.

C-space: Fostering New Creative Paradigms based on Recording and Sharing "Casual" Videos through the Internet

IEEE International Conference on Multimedia & Expo Workshops

IEEE International Conference on Multimedia & Expo Workshops (ICMEW)

A key theme in ubiquitous computing is to create smart environments in which there is seamless integration of people, information, and physical reality. In this manuscript, we describe a set of tools that facilitate the creation of such environments, e,g, a service to transform videos recorded with mobile devices into navigable 3D scenes, a service to compute and describe the emotional processes that occur during the user interaction with such content, a service that takes into account certain dynamic needs of users in personalizing solutions for allocating their leisure time and activities, a gamified crowdsourcing application, and a set of projection-based tools for creating and interacting with augmented environments. Ultimately, our objective is have a framework that seamless integrates all these components, to foster creativity processes.

Cloud-based 3D Reconstruction of Cultural Heritage Monuments using Open Access Image Repositories

GCH 2014. Short Papers - Posters

Eurographics Symposium on Graphics and Cultural Heritage (GCH)

A large number of photographs of cultural heritage items and monuments is publicly available in various Open Access Image Repositories (OAIR) and social media sites. Metadata inserted by camera, user and host site may help to determine the photograph content, geo-location and date of capture, thus allowing us, with relative success, to localise photos in space and time. Additionally, developments in Photogrammetry and Computer Vision, such as Structure from Motion (SfM), provide a simple and cost-effective method of generating relatively accurate camera orientations and sparse and dense 3D point clouds from 2D images. Our main goal is to provide a software tool able to run on desktop or cluster computers or as a back end of a cloud-based service, enabling historians, architects, archaeologists and the general public to search, download and reconstruct 3D point clouds of historical monuments from hundreds of images from the web in a cost-effective manner. The end products can be further enriched with metadata and published. This paper describes a workflow for searching and retrieving photographs of historical monuments from OAIR, such as Flickr and Picasa, and using them to build dense point clouds using SfM and dense image matching techniques. Computational efficiency is improved by a technique which reduces image matching time by using an image connectivity prior derived from low-resolution versions of the original images. Benchmarks for two large datasets showing the respective efficiency gains are presented.

CultLab3D - On the Verge of 3D Mass Digitization

GCH 2014

Eurographics Symposium on Graphics and Cultural Heritage (GCH)

Acquisition of 3D geometry, texture and optical material properties of real objects still consumes a considerable amount of time, and forces humans to dedicate their full attention to this process. We propose CultLab3D, an automatic modular 3D digitization pipeline, aiming for efficient mass digitization of 3D geometry, texture, and optical material properties. CultLab3D requires minimal human intervention and reduces processing time to a fraction of today's efforts for manual digitization. The final step in our digitization workflow involves the integration of the digital object into enduring 3D Cultural Heritage Collections together with the available semantic information related to the object. In addition, a software tool facilitates virtual, location-independent analysis and publication of the virtual surrogates of the objects, and encourages collaboration between scientists all around the world. The pipeline is designed in a modular fashion and allows for further extensions to incorporate newer technologies. For instance, by switching scanning heads, it is possible to acquire coarser or more refined 3D geometry.

Dabei soll langfristig die Qualität der Daten auch wissenschaftlichen Ansprüchen genügen, die bislang Originalvorlagen erfordern. Das System soll hinsichtlich des Aufwands (u.a. Scan-Geschwindigkeit), der erzielbaren Qualität und der Kosten den Markt revolutionieren. Eine Marktreife wird für 2015 erwartet.

KulturBetrieb

Während die digitale Erfassung von kulturellen Artefakten in 2D heute effizient und kostengünstig möglich und bereits weit verbreitet ist, ist die 3D-Digitalisierung noch immer zeit- und kostenintensiv. Gleichzeitig steigt der Wunsch, Museums- und Archivbestände auch in 3D zu erfassen und verschiedenen Anspruchsgruppen zugänglich zu machen. Die vom Fraunhofer IGD entwickelte digitale Scanstraße CultLab3D soll die Digitalisierung dreidimensionaler Objekte revolutionieren.

Modeling a Virtual Robotic System for Cultural Heritage Digitization

Neapel, Univ., Master Thesis, 2014

The objective of this thesis is the development of an inverse kinematic solver application which allows a camera mounted onto the robotic arm to resolve occlusion in a 3D model, by reaching a position and a camera direction, given in this case by a path creator, while in the reality the pose is given from a view planning; The results will be visualized and simulated in a virtual environment which represents the CultArm3D subsystem of the CultLAb3D. This thesis is part of the Cultural Heritage Project of the Fraunhofer Institute for Visual Computing, which is concerned with the development of inexpensive automated 3D-digitization of objects of cultural value. Given that many museums lack exhibition space for their numerous exhibits and that these museums are scattered around the world, the Cultural Heritage Project seeks to provide worldwide virtual access to these exhibits.

3D Research Challenges in Cultural Heritage

Europe is rich in cultural heritage but unfortunately much of the tens of millions of artifacts remain in archives. Many of these resources have been collected to preserve our history and to understand their historical context. Nevertheless, CH institutions are neither able to document all the collected resources nor to exhibit them. Additionally, many of these CH resources are unique, and will be on public display only occasionally. Hence, access to and engagement with this kind of cultural resources is important for European culture and the legacy of future generations. However, the technology needed to economically mass digitize and annotate 3D artifacts in analogy to the digitization and annotation of books and paintings has yet to be developed. Likewise approaches to semantic enrichment and storage of 3D models along with meta-data are just emerging. This paper presents challenges and trends to overcome the latter issues and demonstrates latest developments for annotation of 3D artifacts and their subsequent export to Europeana, the European digital library, for integrated, interactive 3D visualization within regular web browsers taking advantage of technologies such as WebGl and X3D.

4D Reconstruction of the Past

First International Conference on Remote Sensing and Geoinformation of the Environment

International Conference on Remote Sensing and Geoinformation of the Environment (RSCy)

One of the main characteristics of the Internet era we are living in, is the free and online availability of a huge amount of data. This data is of varied reliability and accuracy and exists in various forms and formats. Often, it is cross-referenced and linked to other data, forming a nexus of text, images, animation and audio enabled by hypertext and, recently, by the Web3.0 standard. Search engines can search text for keywords using algorithms of varied intelligence and with limited success. Searching images is a much more complex and computationally intensive task but some initial steps have already been made in this direction, mainly in face recognition. This paper aims to describe our proposed pipeline for integrating data available on Internet repositories and social media, such as photographs, animation and text to produce 3D models of archaeological monuments as well as enriching multimedia of cultural / archaeological interest with metadata and harvesting the end products to EUROPEANA. Our main goal is to enable historians, architects, archaeologists, urban planners and affiliated professionals to reconstruct views of historical monuments from thousands of images floating around the web.

Virtual and Mixed Reality - New Trends: Part I

International Conference on Virtual and Mixed Reality (VMR)

This paper introduces a new low-cost, laser-based 6DOF interaction technology for outdoor mixed reality applications. It can be used in a variety of outdoor mixed reality scenarios for making 3D annotations or correctly placing 3D virtual content anywhere in the real world. In addition, it can also be used with virtual back-projection displays for scene navigation purposes. Applications can range from design review in the architecture domain to cultural heritage experiences on location. Previous laser-based interaction techniques only yielded 2D or 3D intersection coordinates of the laser beam with a real world object. The main contribution of our solution is that we are able to reconstruct the full pose of an area targeted by our laser device in relation to the user. In practice, this means that our device can be used to navigate any scene in 6DOF. Moreover, we can place any virtual object or any 3D annotation anywhere in a scene, so it correctly matches the user's perspective.

A Real-time Low-cost Marker-based Multiple Camera Tracking Solution for Virtual Reality Applications

Journal of Real-Time Image Processing

One of the reasons of how virtual reality applications penetrate industrial production chains slowly is because of significant investment costs to purchase adequate supporting hardware. As a consequence such applications are only available to major companies and fail to benefit the production processes of small and medium enterprises. In this article, we introduce PTrack, a real-time, low-cost, marker-based multiple camera tracking solution for virtual reality providing the accuracy and scalability usually found in much more expensive tracking systems. PTrack is composed of single camera tracking PTrack Units. Each unit is connected to a video camera equipped with infrared strobes and features a novel iterative geometric pose estimation algorithm which does marker-based single camera tracking and is therefore completely autonomous. Multiple PTrack units successively extend the tracking range of the system. For a smooth transition of tracked labels from one camera to another, camera range areas must overlap to form a contiguous tracking space. A PTrack Sensor Fusion Module then computes the pose of a certain label within tracking space and forwards it to interested applications. A universal test setup for optical tracking systems has been built allowing to measure translational and rotational accuracy of PTrack as well as of competing systems.

2010 Proceedings of the Symposium on Simulation for Architecture and Urban Design

Symposium on Simulation for Architecture and Urban Design (SimAUD)

This paper introduces a new augmented reality framework based on a multi-source urban planning backbone aiming at interactively investigating fast "what-if" analysis of urban planning simulations and creating awareness of possible environmental impact. The process of advanced urban planning nowadays includes the simulation of physical phenomena, its analysis, visualization and interpretation in order to evaluate the impact on the layout of the planning. For example, noise and air pollution, annoyances due to both nearby transportation infrastructure and urban traffic have become a serious concern for citizens. In order to provide major aid to the involved stakeholders, especially city managers, new techniques for the preparation, representation and interpretation of the typically large amount of resulting simulation data are required. These must be designed in order to enhance the perceptual and cognitive processes of users to facilitate faster interpretation and decision making. Hence, we introduce a new augmented reality framework which not only allows users to visualize but also to analyze physical phenomena in fast "what-if"- scenarios. By changing boundary conditions, parameters and re-simulating at interactive rates results can be augmented into real world planning layouts. Augmenting reality, urban planning and layouts with resulting simulation data through real-time visualizing tools provides a new and efficient interactive post processing unit for the exploration and analysis of the environmental impact due to changing conditions.
