WebIST 2017
<p><span class="foldable-text" data-reactid="122" id="yui_3_14_1_1_1505396336545_1222">For several years, many researchers tried to semantically integrate geospatial datasets into the semantic web. Although, there are many general means of integrating interconnected relational datasets (e.g. R2RML), importing schema-less relational geospatial data remains a major challenge in the semantic web community. In our project SemGIS we face significant importation challenges of schema-less geodatasets, in various data formats without relations to the semantic web. We therefore developed an automatic process of semantification for aforementioned data using among others the geometry of spatial objects. We combine Natural Language processing with geographic and semantic tools in order to extract semantic information of spatial data into a local ontology linked to existing semantic web resources. For our experiments, we used LinkedGeoData and Geonames ontologies to link semantic spatial information and compared links with DBpedia and Wikidata for other types of information. The aim of our experiments presented in this paper, is to examine the feasibility and limits of an automated integration of spatial data into a semantic knowledge base and to assess its correctness according to different open datasets. Other ways to link these open datasets have been applied and we used the different results for evaluating our automatic approach.</span></p>

Ontology-based Knowledge Representation for Recommendation of Optimal Recording Strategies - Photogrammetry and Laser Scanning as Examples.

2017

S Wefers, A Karmacharya, F Boochs

gis.Science
<p><span style="color: rgb(73, 72, 72); font-family: Roboto, Roboto, &quot;Helvetica Neue&quot;, sans-serif; font-size: 14px; text-align: justify;">Experts&rsquo; knowledge about optical technologies for spatial and spectral recording is logically structured and stored in an ontology-based knowledge representation with the aim to provide objective recommendations for recording strategies. Besides operational functionalities and technical parameters such as measurement principles, instruments, and setups further factors such as the targeted application, data, physical characteristics of the object, and external influences are considered creating a holistic view on spectral and spatial recording strategies. Through this approach impacting factors on the technologies and generated data are identified. Semantic technologies allow to flexibly store this knowledge in a hierarchical class structure with dependencies, interrelations and description logic statements. Through an inference system the knowledge can be retrieved adapted to individual needs.</span></p>

How to optimally record cultural heritage objects? Decision support through connected knowledge.

<p>Optical recording of material cultural heritage (CH) is a multidisciplinary activity where the understanding of cross-disciplinary semantics is vital for a successful completion. In many cases, a lack of understanding of transdisciplinary semantics slows this process down. The end users who are mostly humanities experts lack the technical knowledge of spatial and spectral recording and could therefore demand more than what is actually required or sufficient for the intended CH application. The negotiations between technical experts and the end users are a tedious process. We present a semantic-based decision support system, COSCH<sup>KR</sup>, that employs reasoning and recommends optimal recording technology(ies) according to the application requirements of the recorded and processed data. COSCH<sup>KR</sup> is an ontology-based knowledge model that implies the development of semantic technologies within the Semantic Web framework. It represents formalized knowledge of the disciplines involved in the process of optical recording of material CH. The paper describes the applicability of the model in spatial, spectral, and visualization applications and summarises current possibilities and challenges.</p>

Terrain difficulty as a relevant proxy for objectifying mobility patterns and economic behaviour in the Aurignacian of the Middle Danube region: the case of Stratzing (Austria)

The Exploitation of Raw Materials in Prehistory: Sourcing, Processing and Distribution
<p>This paper addresses the factors that conditioned the choices in lithic resource procurement for tool making at the Late Aurignacian site of Stratzing-Galgenberg (Austria), based on the lithic assemblage from the main area of the site. The raw materials used in the analysed assemblage are varied and partly relate to various local and non-local proveniences. The importance of non-local flint in the assemblage contradicts the distance decay model according to which the amount of a given raw material decreases with the increasing distance from its source. Drawing on the approach developed recently by Lucy Wilson, we examine the predictive ability of &ldquo;source attractiveness&rdquo; with respect to terrain difficulty and energy expenditure to understand why some sources were used more than others, using a Geographic Information System (GIS). Our results indicate that terrain difficulty and mobility costs matter and have a better predictive ability than Euclidean distance alone to explain assemblage variability in the Aurignacian of the Middle Danube region.</p>

<p>From autumn 2010 to spring 2013 the German Archaeological Institute and the Swiss Institute for Architectural and Archaeological Research on Ancient Egypt continued the investigation of the city and temples of Elephantine (Aswan). The preliminary report presents the results of some of the projects conducted during this period.<br />As part of the ongoing rehabilitation work at the museum buildings located on the island of Elephantine, excavations were conducted near the northeastern limit of the ancient town. Among the earliest remains found in the area is a well preserved section of the city wall of the late 2nd dynasty. Outside the perimeter of this wall Nile sediments dating to the Old Kingdom were identified, as well as settlement remains of the 6th to 12th dynasties. Several pottery kilns of the early Middle Kingdom were discovered here. A later city wall appears to have been constructed during the reign of Senwosret III and it seems to have existed until the early New Kingdom.<br />The documentation and study of the relief blocks originating from the Khnum temple of the New Kingdom was continued. Many of the blocks can be attributed to the temple house, the courtyard and the first pylon built by Thutmosis III, as well as to the festival courtyard which was added by Amenophis II. Some of the blocks appear to originate from other, so far unknown buildings of the temple complex, including a cult building of Thutmosis I and II, a barque station of Hatshepsut and a construction of Thutmosis IV.<br />The aim of another project has been the investigation of workshop areas of the Late Antique Period. During the excavation of a house dating to the 5th&ndash;9th centuries AD, evidence for the baking of bread, the keeping of animals and the production of granodiorite bowls has been found. Nearby an oven used for smelting non-ferrous metal was identified. Fragments of melting pots, casting molds and slag provide information on the production process.</p>

The Labelling System: A Bottom-up Approach for Enriched Vocabularies in the Humanities

2016

Thiery, F., Thomas Engel

43rd Annual Conference on Computer Applications and Quantitative Methods in Archaeology, CAA 2015
<p>Shared thesauri of concepts are increasingly used in the process of data modelling and annotating resources in the Semantic Web. This growing family of linked data resources follows a top-down principle. In contrast, the Labeling System follows a bottom-up approach, enabling scientists working in the digital humanities to manage, create and publish their own controlled vocabularies in SKOS (Simple Knowledge Organization System). The created concepts can then be interlinked with well-known LOD (Linked Open Data) resources, a process named the &lsquo;Labeling Approach&rsquo;. The Labeling System is domain independent, while uniting perspectives of different scientific disciplines on the same label and therefore contributing to interdisciplinary collaboration for building up cross and inter-domain linked data communities. This paper addresses principles of the Labeling System in the light of archaeological use cases.</p>

<p><span class="pb_abstract">For many years FIG, the International Association of Surveyors, has been trying to bridge the gap between surveyors and the geospatial society as a whole, with the geospatial industries in particular. Traditionally the surveying profession contributed to the good of society by creating and maintaining highly precise and accurate geospatial data bases, based on an in-depth knowledge of spatial reference frameworks. Furthermore in many countries surveyors may be entitled to make decisions about land divisions and boundaries. By managing information spatially surveyors today develop into the role of geo-data managers, the longer the more. Job assignments in this context include data entry management, data and process quality management, design of formal and informal systems, information management, consultancy, land management, all that in close cooperation with many different stakeholders. Future tasks will include the integration of geospatial information into e-government and e-commerce systems. The list of professional tasks underpins the capabilities of surveyors to contribute to a high quality geospatial data and information management. In that way modern surveyors support the needs of a geo-spatial society. The paper discusses several approaches to define the role of the surveyor within the modern geospatial society.</span></p>

<p>Application and analysis capabilities of 3D data sets generated through UAV photogrammetry are presented on the basis of an exemplary millstone quarry of the so-called Mayen quarry district (Germany). In general, millstone quarries are technical cultural heritage sites which give evidence for economic interpretations as they are of interest for the reconstruction of ancient procurement patterns. Particularly those quarries which had a high economic impact cover large areas with often arduous accessibility. Therefore, photogrammetric recording using a UAV is the best approach for fast and inexpensive high-quality documentation. The images are used to create a 3D data set and orthophoto. For analysis and interpretation the Spatial Image analysis and Visualisation Tool (SIVT) of i3mainz is used allowing a variety of interactive visualization functionalities. The 3D data are transformed into 2.5D data enabling segmentation of spatial information and volume calculations. Both functionalities support the cultural heritage expert&#39;s research: On the one hand the interactive segmentation allows producing a map of the quarry displaying only those parts associated with the extraction. On the other hand the output of the quarry including debris and millstone blanks can be calculated easily. All in all, the entire workflow beginning with data capture using a UAV followed by data processing, (2.5D / 3D) data analyses and visualisation of the results is presented.</p>

Virtual Archaeology Review
<p>The Château de Germolles is one of the rare palaces in France dating from the 14 th century. The noble floor is decorated with wall paintings that are a unique example of courtly love spirit that infused the princely courts of the time. After being concealed sometime in the 19 th century, the paintings were rediscovered and uncovered in the middle of the 20 th century and partly restored at the end of the 1990s. No scientific documentation accompanied these interventions and important questions, such as the level of authenticity of the mural decorations and the original painting technique(s) used in the medieval times remained unanswered. The combined scientific and financial supports of COSCH COST Action and DRAC-Burgundy enabled to study Germolles&#39; wall paintings using some of the most innovative imaging and analytical techniques and to address some of the questions raised. The study provided significant information on the material used in the medieval times and on the conservation condition of the paintings. The data collected is vast and varied and exposed the owners of the property to the challenges of data management.</p>

Ein Modell der Interoperabilität für GIS-Anwender im Rahmen von INSPIRE

<p>Mit INSPIRE &ndash; der Geodateninfrastruktur der Europäischen Gemeinschaft &ndash; wird das Ziel verfolgt, umweltrelevante und harmonisierte Geodatenbestände für eine nachhaltige europäische Umweltpolitik und zur allgemeinen Bereitstellung für die Bürger der EU verfügbar zu machen. Die Konzeption und Umsetzung von Diensten der Behörden in Europa muss auf der Grundlage von vernetzten Datenbanken erfolgen. Zur Gewährleistung einer Interoperabilität zwischen den verschiedenen Ebenen und Systemen ist es zwingend notwendig, dass auf den verschiedenen Ebenen die Behörden und Systeme über gemeinsame Standards kommunizieren. Dabei sind sowohl semantische, syntaktische und organisatorische Rahmenbedingungen der Verwaltungen zu berücksichtigen. Diese spiegeln sich vor allem in den vorhandenen E-Government-Aktivitäten, Standardisierungen und Geoinformationssystemen (GIS) der Verwaltung wider. Zur Realisierung einer Geodateninfrastruktur in der Europäischen Gemeinschaft sollen die Mitgliedsstaaten ihre bereits vorhandenen Geodatensätze und -dienste stufenweise interoperabel verfügbar machen. Damit soll die Entscheidungsfindung in Bezug auf politische Konzepte und Maßnahmen, die direkte oder indirekte Auswirkungen auf die Umwelt haben können, unterstützt werden. Jedoch haben die gewachsenen Verwaltungsstrukturen in Städten und Landkreisen mit ihren jeweiligen Besonderheiten zu heterogenen Datenbeständen geführt. In dem entwickelten E-Government-Modell einer Geodateninfrastruktur (Geo-Government) kann Interoperabilität auf allen Ebenen nachgewiesen werden.</p>

Development of a platform recommending 3D and spectral digitisation strategies.

2016

S Wefers, A Karmacharya, F Boochs

Virtual Archaeology Review
<p>Spatial and spectral recording of cultural heritage objects is a complex task including data acquisition, processing and analysis involving different technical disciplines. Additionally, the development of a suitable digitisation strategy satisfying the expectations of the humanities experts needs an interdisciplinary dialogue often suffering from misunderstanding and knowledge gaps on both the technical and humanities sides. Through a concerted discussion, experts from the cultural heritage and technical domains currently develop a so-called COSCH KR (Colour and Space in Cultural Heritage Knowledge Representation) platform that will give recommendations for spatial and spectral recording strategies adapted to the needs of the cultural heritage application. The platform will make use of an ontology through which the relevant parameters of the different domains involved in the recording, processing, analysis, and dissemination of cultural heritage objects are hierarchically structured and related through rule-based dependencies. Background and basis for this ontology is the fact that a deterministic relation exists between (1) the requirements of a cultural heritage application on spatial, spectral, as well as visual digital information of a cultural heritage object which itself has concrete physical characteristics and (2) the technical possibilities of the spectral and spatial recording devices. Through a case study which deals with the deformation analysis of wooden samples of cultural heritage artefacts, this deterministic relationship is illustrated explaining the overall structure and development of the ontology. The aim of the COSCH KR platform is to support cultural heritage experts finding the best suitable recording strategy for their often unique physical cultural heritage object and research question. The platform will support them and will make them aware of the relevant parameters and limitations of the recording strategy with respect to the characteristics of the cultural heritage object, external influences, application, recording devices, and data.</p>

SEMANTIC CATALOGUE TO MANAGE DATA SOURCES IN DISASTER MANAGEMENT SYSTEM

<p><span class="foldable-text" data-reactid="118" id="yui_3_14_1_1_1505396728757_1230">With the climate change, disasters occur more frequently and the need for efficient disaster management systems becomes highly recommended to save lives. This paper deals with a study of existing systems, with the intention of determining the main recent improvement in the domain. The heterogeneous data integration process is a major central point. Thus, a semantic system with three main components is proposed as a new position in the disaster management systems. These three components are a knowledge base, a reasoner and a semantic catalogue. The knowledge base provides a controlled vocabulary and allows storing information retrieval. The semantic catalogue facilitates the access to data sources adapted to user&#39;s and agent&#39;s needs. The reasoner analyzes the information in the knowledge base thus replying to the user queries. In addition, the reasoner aims at adding automatically new data sources in the semantic catalogue. The fast access to a great number of data sources is of benefit for decision-making systems such as disaster management systems.</span></p>

Interdisciplinary Dialogue Towards an Enhanced Understanding of Optical Techniques for Recording Material Cultural Heritage - Results of a COST Action

2016

<p>The COST Transdomain Action TD1201, Colour and Space in Cultural Heritage [COSb], 2012-2016, contributes to the conservation and preservation of cultural heritage (CH) by enhancing shared understanding, between experts from various disciplines, of the spectral and spatial recording of physical CH objects. Optimal recording, adapted to the requirements of a CH application, should involve experts from multiple disciplines and industries. Such an interdisciplinary approach is necessary &quot;in order to protect, preserve, analyze, understand, model, virtually reproduce, document and publish important CH in Europe and beyond&quot; [COSa]. In order to fulfil this goal, experts from 28 European countries entered into a multidisciplinary dialogue trying to establish a common understanding of spatial and spectral recording techniques best suited for particular CH applications. Several COSCH groups worked on the characterisation of spatial and spectral recording techniques; the use of algorithms and processing chains; and requirements of analysis, restoration and visualisation of CH surfaces and objects. A range of possible applications of optical techniques, now available to recording and examination of CH objects, have been tested through six COSCH case studies [BKM17]. These projects have exposed the challenges of common understanding of the processes involved, and differences in disciplinary research needs and methods. A number of issues have been identified, sometimes as basic as lack of common specialist terminology and relevant technical standards. The complexity of the field became apparent in the course of designing COSCHKR, ontological knowledge representation, which employs semantic technologies. After four years of interdisciplinary dialogue, COSCH leaves a legacy that will help the dialogue to continue, technology to develop, and specialist training to better respond to the actual needs of the interdisciplinary CH research communities.</p>

Digital 3D Reconstructed Models – Structuring Visualisation Project Workflows

<p>Cultural Heritage (CH) visualisations have to be understood as a combination of research sources, the contemporary historical and cultural context (Zeitgeist), project background and work process. All available information is collected, consolidated, filtered and assembled into a coherent picture. In case of digital 3D reconstructed models, the result is a digital data set that can be processed for different application fields. They are understood as a result of a complex creative process and as a synthesis of a CH research project, its CH context, the available research source material, and the modeling process itself. For all visualisation types in CH different conditions, factors, and basic rules apply to achieve a high quality result. Two examples are presented illustrating the structured view on visualisation projects as such. This paper seeks to differentiate the various research sources being the basis for digital 3D reconstructed models and defines work phases allowing a quality assessment. Furthermore, the potentials of including this structured view into the ontology COSCHKR currently under development is discussed. In combindation with traditional guidelines COSCHKR platform could open up new and flexible approaches.</p>

Knowledge Based Recommendation on Optimal Spectral and Spatial Recording Strategy of Physical Cultural Heritage Objects

2016

A Karmacharya, S Wefers, F Boochs

SEMAPRO 2016: The 10th Internat. Conference on Advances in Semantic Processing
<p>Ontologies have traditionally been used to represent knowledge of a specific domain. They are also used to provide a base to infer the knowledge present inside them. However, the applications of ontologies within the Cultural Heritage (CH) community have been restricted to providing standard documentation for significant heritage objects. E.g., widely used ontology within CH disciplines, International Committee for Documentation Conceptual Reference Model (CIDOC CRM) is designed to provide standards in documenting archival information of physical CH object. There has been hardly any work relating the objects to their documentation purposes. In this paper, we present the Colour and Space in Cultural Heritage Knowledge Representation (= COSCHKR) ontology &ndash; a multi-faceted ontology. With COSCHKR, we present a system that infers inter-woven descriptive semantics of different involved CH disciplines in recording CH objects to recommend optimal spatial and spectral technical solutions to humanities experts and guide through the underlying complexities while recording their objects. It takes numbers of facts into consideration including physical characteristics of the CH objects, the characteristics of their surroundings and even other relevant facts such as budget or staff competence to infer against the characteristics of the technologies for a proper recommendation. In contrast to a typical Recommender System, which does the same for web-based content through stochastic methods, we use descriptive semantics at the concept level.</p>

The Late Antique and Byzantine Workshop- and Milling-complex in Terrace House 2 of Ephesos (Turkey) - Relative Chronology and Wheelrace Construction

2016

S Wefers

Actes du colloque international, Lons-le-Saunier du 2 au 5 novembre 2011
<p>The workshop and milling complex in Terrace House 2 comprises seven mills and one stone-sawing machine. Each were powered by a waterwheel. Based on the different features, it is possible to identify three building phases. The first comprised at least two mills powered by two independent waterwheels. The second had at least one mill. In the third phase five waterwheels drove four mills and one stone-sawing machine. In addition, it is possible to distinguish between two different types of waterwheel constructions.</p>

Computational Science and Its Applications -- ICCSA 2016
<p>The paper presents work on implementation of semantic technologies within a geospatial environment to provide a common base for further semantic interpretation. The work adds on the current works in similar areas where priorities are more on spatial data integration. We assert that having a common unified semantic view on heterogeneous datasets provides a dimension that allows us to extend beyond conventional concepts of searchability, reusability, composability and interoperability of digital geospatial data. It provides contextual understanding on geodata that will enhance effective interpretations through possible reasoning capabilities. &nbsp;We highlight this through use cases in disaster management and planned land use that are significantly different. This paper illustrates the work that firstly follows existing Semantic Web standards when dealing with vector geodata and secondly extends current standards when dealing with raster geodata and more advanced geospatial operations.</p>

Location Based Sensing for Health Diagnoses: A Prototype for Personalized Pollen Profiling

2015

K Böhm, N Bock, T Sehlinger

GI_Forum - Journal for Geographic Information Science
<p>Personalized information and forecasts of environmentally triggered medical symptoms are becoming more and more critical, since the numbers of patients suffering from environmentally induced symptoms is still increasing (e.g. allergy or asthma patients). This project aimed at developing a solution to enable gathering personalized pollen exposure information and mapping this information with geospatial data from the personal habitat. This enables personal forecasts based on geospatial information and, when distributed to other suffering individuals, gives them the possibility of avoiding harmful environments. Within an interdisciplinary team of researchers from the medical, engineering, and geoinformatics professions, a system was developed to gather, qualify, and quantify aeroallergen particles (pollen), monitor additional climate parameters, and map this information, together with geospatial information, to the daily habitat of a single individual.</p>

Semantic based Structuring of 3D technologies for their optimized use in cultural heritage documentation.

2015

A Karmacharya, S Wefers, F Boochs

43rd Conference of Computer Applications and Quantitative Methods in Archaeology, CAA 2015, Siena, Book of Abstracts.
<p>Constant technological progress results in new possibilities to produce reliable and rich spatial data of cultural heritage objects: for instance, museums have started to digitize their collections, more and more archaeological excavations or features and entire CH buildings have been documented in 3D. It is now necessary to establish connections among different CH disciplines and several technical disciplines, and to work on collaborative projects.</p><p>Technicians and CH experts together evaluate the best technique for specific CH object documentation, implementation and use. This discussion arises from the knowledge gaps of each counterpart in respect to the other discipline. Projects such as Agora 3D (see below) clearly demonstrate the need for an evaluation of the different available techniques.</p><p>In order to make optimal use of these technological capabilities, it is important to identify and name the information required to best serve the reasoning processes in these application fields. Correspondingly it is necessary to know about the characteristics of digitization techniques producing the content adapted to the needs of the applications. Due to the considerable complexity of instruments and processes producing the data, it is helpful to have a clear structure which relates the capabilities of the instruments to the requirements of the applications.</p><p>The COST Action TD1201 &ldquo;Colour and Space in Cultural Heritage (COSCH)&rdquo; takes this need into account, aiming to enhance the understanding among these disciplines. We will focus on the already listed, structured and evaluated available 3D technologies. At the same time, experts in spectral and CH research started to list, structure, and evaluate their knowledge. These evaluations yield a structure of technologies, and ultimately the techniques and instruments using their characteristics. The understanding of these characteristics provides insights for their potential applications. The ontology knowledge model accessible through so-called &ldquo;COSCH<sup>KR </sup>App&rdquo; provides a knowledge structure. It benefits from the development of semantic technologies from the Semantic Web framework. Semantics, which provide meanings, are captured through the conceptual structure and are defined through the ontology. The overall aim of this ontology is the development of a software tool to enable a better understanding of data acquisition techniques and their support to optimally realize cultural heritage applications.</p>

Semantisch angereicherte 3D-Messdaten von Kirchenräumen als Quellen für die geschichtswissenschaftliche Forschung

2015

Felix Lange, Martin Unold

Zeitschrift für digitale Geisteswissenschaften (ZfdG), Grenzen und Möglichkeiten der Digital Humanities, Sonderband 1
<p>Der vorliegende Beitrag gibt einen Einblick in raumbezogene epigraphische Forschungen von mittelalterlichen und frühneuzeitlichen Kirchen im Rahmen des Forschungsprojektes <i>Inschriften im Bezugssystem des Raumes</i> (IBR). Dieses in den Spatial Humanities angesiedelte Vorhaben nutzt mit Hilfe einer speziell für diesen Zweck entwickelten Erfassungssoftware Punktwolken aus terrestrischen Laserscannings als Primärquelle für die Raumanalyse. Zusammen mit epigraphischen Fachdaten und Annotationen entsteht so die Datengrundlage für die Untersuchung vielfältiger Sinn- und Funktionsbezüge von Objekten in Kircheninnenräumen.</p>

Netzmessungen mit dem Leica Absolute Tracker AT402 zur Bestimmung geodätischer Prüfstrecken

2015

P. Arent, R. Bretscher, M SchlĂĽter

Allgemeine Vermessungs-Nachrichten (avn)
<p>Zur Bestimmung geodätischer Prüfstrecken unter Nutzung eines Leica Absolute Trackers AT402 stellen wir Konzept und Ergebnisse vor. Dazu greifen wir die positiven Erfahrungen mit Lasertrackern beim Ringversuch auf der neuen Kalibrierbasis der Universität der Bundeswehr München zwischen 2009 und 2011 auf.<br />Im Unterschied zum Ringversuch konzentrieren wir uns auf die Bestimmung neuer und bestehender Prüfstrecken im derzeit üblichen Pfeilerdesign mit einer Pfeilerkopf-Abschlussplatte mit 5/8-Zoll-Gewindezapfen zur Dreifußaufnahme. Dafür schlagen wir eine Netzmessung unter Verwendung einfacher Pfeiler-Aufsatzadapter vor. Abschließend vergleichen wir unsere Ergebnisse, die bei unterschiedlichen meteorologischen<br />Bedingungen auf der Eichstrecke Weinolsheim des Landes Rheinland-Pfalz gewonnen wurden.</p>

Photogrammetrie, Laserscanning, Optische 3D-Messtechnik. Beiträge der Oldenburger 3D-Tage 2015
<p>Dieser Beitrag befasst sich mit dem Einfluss der Zielmarkenexzentrizität während der Kamera-<br />Kalibrierung in Kombination mit verschiedenen Kalibrierkörpern. Zunächst wird<br />deren Einfluss auf die Resultate anhand numerischer Simulationen nachgewiesen. In diesen<br />Simulationen wird eine Erfassung des Einflusses der Exzentrizität auf Bildmessung, Objekt-<br />und Kamerageometrie angestrebt. Im zweiten Schritt wird eine Realkalibrierung mit<br />vergleichbarer Aufnahmekonfiguration durchgeführt. Dabei werden Gemeinsamkeiten bzw.<br />Unterschiede der erreichten Ergebnisse diskutiert sowie eine mögliche Kompensation des<br />Einflusses in der Praxis erörtert.</p>
