Intérêt des groupes avec médiations
Authors: Thomas Marie , Drieu Didier , Jerar Oulidi Jalal , de Fleurian Aymeric
Published: June 2016

Le travail groupal avec médiations peut soutenir la symbolisation dans les soins aux adolescents vulnérables. Comme dans le psychodrame, le dispositif d’un groupe « trouvé/créé » – ici avec des jeunes d’un hébergement thérapeutique – et le support de la narrativité (cartes, histoires fantastiques, récit imagé et partagé) peuvent mobiliser une dynamique d’interfantasmatisation et déjouer ainsi la violence d’incorporats traumatiques qui sidèrent les processus d’adolescence.
Kontakthof : le groupe et la danse
Authors: Lippi Silvia
Published: June 2016

À travers l’analyse du spectacle Kontakthof avec des adolescents de plus de quatorze ans, de Pina Bausch, nous interrogerons le corps, le désir, la castration, le rêve et l’identification à l’adolescence. Nous verrons comment peut se constituer un groupe qui ne se rassemble pas autour d’un idéal protecteur, mais à partir du désir. Ce désir est en rapport avec le rêve et le jeu, et se manifeste à travers la pratique de la danse.
L’approche globale à l’européenne
Authors: Egger Clara
Published: June 2016

Cet article s’intéresse à la façon dont les rivalités entre les acteurs européens au sein de la configuration de la gestion de crise européenne en Somalie ont façonné un modèle propre à l’UE en la matière. À partir de données collectées sur le terrain au moyen d’entretiens, l’article plaide pour une meilleure prise en compte des stratégies conflictuelles des acteurs européens dans l’analyse de la politique étrangère européenne. Dans cette perspective, il présente deux résultats empiriques pour expliquer quelques-unes des spécificités du modèle européen, respectivement sur l’autonomie de la politique humanitaire et sur les objectifs stratégiques de l’action de l’UE en Somalie.
L’Europe des militaires
Authors: Rayroux Antoine
Published: June 2016

Cet article montre les limites de l’institutionnalisation de l’approche globale dans la pratique des militaires européens en opération. Une analyse d’EUFOR Tchad/ RCA fait ressortir deux observations contrastées. Certes, l’approche globale trouve un écho favorable auprès des militaires européens, en ce qu’elle leur permet de développer de nouvelles compétences professionnelles et sociales au contact les uns des autres et avec les autres acteurs du champ de la sécurité européenne. L’approche globale est une norme qui contribue pour les militaires à donner du sens au rôle de l’UE comme acteur de la gestion des crises. Cependant, sa mise en œuvre sur le terrain donne lieu à un assemblage de pratiques diverses et au rejet par les militaires d’un certain nombre de ses principes, dès lors que ces derniers mettent en danger la conduite des opérations.
La sexualité dans le mariage. Un avant-goût du Paradis
Authors: Bellakhdar Saïd
Published: June 2016

Le fait que l’islam soit une religion sans clergé ni intercesseur auprès de Dieu implique qu’il y ait plusieurs interprétations des énoncés du Coran, texte sacré des musulmans et à prendre en compte les pratiques religieuses en fonction des époques, des lieux et des contextes et plus particulièrement l’endogamie qui a longtemps imposé le mariage entre cousins. Le Coran prescrit la sexualité de personnes de sexes différents dans le mariage et rejette formellement toutes les autres pratiques. Certains théologiens comme Ghazali ont affirmé que la sexualité dans le mariage offre un avant-goût du Paradis pour récompenser la piété des croyants. Certains courants d’un islam populaire ont décrit le Paradis selon leur désir. Ce Paradis promis a une fonction de consolation par rapport à la vie difficile menée ici bas.
De la différence à l’émergence d’une question : sur la modalité distinctive du monothéisme juif
Authors: Squverer Amos
Published: June 2016

Le judaïsme, propose Lacan, met en acte une mode de différentiation, une forme de distinction qui lui est constitutif et qui devrait être interrogé par la psychanalyse. L’auteur propose de dégager la modalité originale de ce mode de différenciation soit la modalité par laquelle il fonde son identité collective tout en problématisant l’idée même de l’identité. L’auteur prend appui sur les travaux de l’égyptologue Jan Assmann qui esquisse la distinction monothéiste comme un acte violent. Le monothéisme se constituerait comme une « vraie » religion rejetant dans le « faux » et l’exclusion la théologie polythéiste qui le précède. L’intolérance lui serait alors inhérente. Assmann décrit comme alternative une sphère polythéiste pré-monothéiste qui serait bien plus tolérante, ouverte et capable de contenir en elle une multiplicité culturelle. En s’appuyant sur ces travaux, l’auteur y introduit un écart et dégage une autre modalité de constitution. Entre l’affirmation violente du monothéisme et son envers, le retour au polythéisme, se dégage ici une troisième voie.
La destruction des dieux d’autrui, une singularité abrahamique
Authors: Castel Jean-Pierre
Published: June 2016

Les religions abrahamiques se distinguent des autres religions non pas tant par leur éthique ou par leur rationalité que par un complexe d’exclusivisme, bâti autour des notions de vérité révélée, de dieu jaloux, d’idolâtrie, et par la sacralisation d’un texte prescriptif. Au nom du devoir d’extirpation de l’idolâtrie, elles ont commis plus de violences religieuses que toute autre religion. À quoi elles opposent un formidable déni.
Femtosecond Laser-Assisted Cataract Surgery After Radial Keratotomy
Authors: Noristani Rozina , Schultz Tim , Dick H. Burkhard
Published: June 2016

PURPOSE:

To determine the efficacy of femtosecond laser-assisted cataract surgery in eyes with radial keratometry.

METHODS:

Femtosecond laser-assisted cataract surgery was performed in 3 patients (6 eyes) who had six to eight radial keratotomy incisions.

RESULTS:

In all cases, the anterior segment of the eye was visualized with integrated three-dimensional optical coherence tomography and it was possible to position the laser corneal incisions between the radial keratotomy incisions. No intraoperative complications occurred. In particular, no corneal perforation, anterior capsular tears, or discontinuities could be detected. No corneal leakage or other postoperative complications were noted on follow-up after 6 weeks and 6 months.

CONCLUSIONS:

Femtosecond laser-assisted cataract surgery presents a new, feasible, and safe surgical technique for patients with cataract who had previous radial keratotomy.

Ex Vivo Transepithelial Collagen Cross-linking in Porcine and Human Corneas Using Human Decorin Core Protein
Authors: Metzler Kimberly M. , Roberts Cynthia J. , Mahmoud Ashraf M. , Agarwal Gunjan , Liu Jun
Published: June 2016

PURPOSE:

To investigate changes in corneal biomechanics after cross-linking with human decorin core protein (decoron), which is a small, naturally occurring proteoglycan that bridges collagen fibrils, organizing and stabilizing lamellar collagen architecture.

METHODS:

Five human donor pairs (10 eyes) and 5 porcine pairs (10 eyes) had one random eye treated transepithelially with decoron, with the untreated fellow eye serving as control. Pretreatment (45 to 60 seconds) and penetration enhancer (45 to 60 seconds) preceded instillation of decoron (45 to 60 seconds). Total treatment time was less than 4 minutes per eye. Human donor eyes were evaluated using the CorVis ST (Oculus Optikgeräte GmbH, Wetzlar, Germany) at 15, 20, 30, 40, and 50 mm Hg of intraocular pressure. Elastic modulus was calculated for human corneas, using parameters derived from Scheimpflug images. Analysis of variance was performed. Porcine corneas underwent uniaxial tensile testing with a Rheometrics Systems Analyzer (RSA III; TA Instruments, New Castle, DE). Secant modulus was calculated and paired
t
tests were performed between treated and control groups.

RESULTS:

One human eye pair was excluded based on initial corneal thickness greater than 850
µ
m. Analysis of variance of the included four pairs demonstrated a significant treatment effect (
P
< .05) in deformation amplitude, first applanation velocity, initial curvature, and pachymetry, with all lower in the treatment group, consistent with stiffening and cross-linking. Elastic modulus demonstrated a significant treatment effect with a higher elastic modulus in the treatment group. In porcine eye pairs, the secant modulus was significantly higher in the treated than the untreated corneas at 4%, 5%, and 6% strain (
P
< .05).

CONCLUSIONS:

Treatment with decorin core protein produced stiffer biomechanical behavior and higher elastic modulus in both human and porcine corneas in this preliminary ex vivo study. Further studies are needed to evaluate clinical safety, efficacy, and long-term stability.

The effect of twig diameter on emergence rates of the oak twig pruner (Coleoptera: Cerambycidae)
Authors: Brown William P. , Zuefle Marion E. , Dombroskie Jason J.
Published: June 2016

Oak twig pruner (Anelaphus parallelus(Newman); Coleoptera: Cerambycidae) larvae develop inside twigs pruned from host plants. Reasons for this behaviour are unknown and differential emergence due to twig diameter has not been explored. Twigs pruned from walnuts (Juglans nigraLinnaeus; Juglandaceae) (n=179) and oaks (QuercusLinnaeus; Fagaceae) (n=84) were collected in Pennsylvania, United States of America in 2010; 118 pruned oak twigs were collected in New York State, United States of America in 2012. Twigs from 2012 were dissected to determine rates of emergence and larval mortality; both samples were examined for parasitoids. As the diameter of oak twigs (range of 3–16 mm) increased, larval mortality increased and adult emergence decreased. Date of collection did not influence twig diameter nor emergence rates. Three new parasitoids were associated with the oak twig pruner:AtanycolusFörster (Hymenoptera: Braconidae),Eubazus denticulatus(Martin) (Hymenoptera: Braconidae), and a potentially new genus of wasp (Hymenoptera: Braconidae, Hormiinae nearPambolusHaliday). Parasitism rates were an order of magnitude greater among twigs that contained more than one larva or pupa (23.1%;n=26) compared to those that contained only one (2.3%;n=341).
Recurrent angina from chronic coronary obstruction following transcatheter aortic valve implantation
Authors: Kabach Mohamad , Alrifai Abdulah , Furlan Stefanie , Alahdab Fares
Published: June 2016

Severe aortic stenosis and coronary artery disease often coexist. Coronary angiography (CA) and percutaneous coronary intervention (PCI) can be challenging in patients with prior transcatheter aortic valve implantation (TAVI). Depending on the type and position of the implanted valve, the procedure can be challenging or even unfeasible due to interference of diagnostic catheters and valve parts. The correct positioning of the TAVI prosthesis during TAVI was identified as an important factor with regard to the feasibility of subsequent CA or PCI. TAVI has been also associated with vascular, cerebrovascular and conduction complication. One is rare but life-threatening complication, coronary ostial obstruction. Coronary ostial obstruction can develop, especially if a safety check of more than 10 mm of coronary ostial height is not taken into consideration during TAVI. This complication can cause recurrent episodes of angina and can severely worsen the patient′s cardiac systolic function.
Key Points to Facilitate the Adoption of Computer-Based Assessments
Authors: Burr S.A. , Chatterjee A. , Gibson S. , Coombes L. , Wilkinson S.
Published: June 2016

There are strong pedagogical arguments in favor of adopting computer-based assessment. The risks of technical failure can be managed and are offset by improvements in cost-effectiveness and quality assurance capability. Academic, administrative, and technical leads at an appropriately senior level within an institution need to be identified, so that they can act as effective advocates. All stakeholder groups need to be represented in undertaking a detailed appraisal of requirements and shortlisting software based on core functionality, summative assessment life cycle needs, external compatibility, security, and usability. Any software that is a candidate for adoption should be trialed under simulated summative conditions, with all stakeholders having a voice in agreeing the optimum solution. Transfer to a new system should be carefully planned and communicated, with a programme of training established to maximize the success of adoption.
The burying and grazing effects of Plateau pika on alpine grassland are small: A pilot study in a semi-arid basin on the Qinghai-Tibetan Plateau
Authors: Yi Shuhua , Chen Jianjun , Qin Yu , Xu Gaowei
Published: June 2016

Abstract. There is considerable controversy about the role of Plateau pika (Ochotona curzoniae) in alpine grassland on the Qinghai-Tibetan Plateau (QTP). It is on one hand considered as a keystone species, on the other hand poisoned. Although significant amount of efforts have been made to study the effects of Plateau pika at a quadrat scale (~ m2), our knowledge about its distribution and effects at a larger scale is very limited. In this study, we investigated the direct effects, i.e. burying and grazing, of pika by upscaling field sampling at a quadrat scale to a plot scale (~ 1,000 m2) by aerial photographing. Altogether, 168 plots were set on 4 different types of alpine grassland in a semi-arid basin on the QTP. Results showed that: 1) the effects of burying by pika piles on the reduction of vegetation cover, biomass and soil carbon/nitrogen were less than 10 %, which was much smaller than the effects of bald patches; and 2) pika consumed 8–21 % of annual net primary production of grassland. We concluded that the direct burying and grazing effects of pika on alpine grassland were minor in this region. Quadcopter is an efficient and economic tool for long-term repeated monitoring over large regions for further understanding the role of pika.
Voxel inversion of airborne electromagnetic data for improved groundwater model construction and prediction accuracy
Authors: Christensen N. K. , Ferre T. P. A. , Fiandaca G. , Christensen S.
Published: June 2016

Abstract. We present a workflow for automated construction and calibration of large-scale groundwater models that includes the integration of airborne electromagnetic (AEM) data and hydrological data. The AEM data are inverted to form a 3D geophysical model. The parameter of interest is the hydraulic conductivity, which can be determined by translating the 3D geophysical model, using a petrophysical relationship, to form a 3D hydraulic conductivity distribution. We use the geophysical models and hydrological data to determine the optimum spatially distributed petrophysical relationship. The two shape factors of the petrophysical relationship primarily work as translators between resistivity and hydraulic conductivity, but the shape factors can also compensate for structural defects in the model. The method is demonstrated for a synthetic case study. The AEM data are inverted with both smoothness (smooth) and minimum gradient support (sharp) constraints, resulting in two competitive geophysical models. The value of the AEM data quality is tested by inverting the alternative geophysical models using data corrupted with four different levels of background noise. Subsequently, the geophysical models are used to construct two competing groundwater models. The performance of the flow model was tested for four types of prediction. All predictions occurred beyond the calibration base. Predictions of a pumping well's recharge area and groundwater age were applying the same stress situation as applied during hydrologic model calibration, while predictions of head and stream discharge was done for a stress situation changed from those applied during hydrologic model calibration. The results show that geophysical models inverted with sharp constraints improve the predictive capability of the groundwater models compared to geophysical models inverted with smooth constraints. It was found that the use of sharp models improves the prediction of recharge area, while prediction of groundwater age does not improve significantly. When the stress situation is changed the prediction of head change and stream discharge improves significantly for sharp models compared to smooth models. This is especially true for predictions of head change made in the vicinity of the pumping well and far-away from hydrologic boundaries. Furthermore, the geophysical data quality has variable influence on different model predictions. Prediction accuracy improves with AEM data quality for predictions of recharge area, head change and stream discharge, while the accuracy appears to not improve for prediction of groundwater age.
INDUSTRIAL PHOTOGRAMMETRY - ACCEPTED METROLOGY TOOL OR EXOTIC NICHE
Authors: Bösemann Werner
Published: June 2016

Abstract. New production technologies like 3D printing and other adaptive manufacturing technologies have changed the industrial manufacturing process, often referred to as next industrial revolution or short industry 4.0. Such Cyber Physical Production Systems combine virtual and real world through digitization, model building process simulation and optimization. It is commonly understood that measurement technologies are the key to combine the real and virtual worlds (eg. [Schmitt 2014]). This change from measurement as a quality control tool to a fully integrated step in the production process has also changed the requirements for 3D metrology solutions. Key words like MAA (Measurement Assisted Assembly) illustrate that new position of metrology in the industrial production process. At the same time it is obvious that these processes not only require more measurements but also systems to deliver the required information in high density in a short time. Here optical solutions including photogrammetry for 3D measurements have big advantages over traditional mechanical CMM’s. The paper describes the relevance of different photogrammetric solutions including state of the art, industry requirements and application examples.
VIRTUAL AND PHYSICAL RECOMPOSITION OF FRAGMENTED ECCLESIASTICAL FRESCOES USING A PHOTOGRAMMETRIC APPROACH
Authors: Abate D. , Hermon S. , Eliades I.
Published: June 2016

Abstract. The octagonal domed church of the Christ Antiphonitis in the district of Kyrenia (Cyprus) was originally completely decorated with frescoes along its interior walls. Two of these are exceptional for their artistic and historic value: the story of the Tree of Jesse (a pictorial genealogy of the Virgin) located on the southern wall of the octagon, and the Last Judgment, on the northern wall. Following the invasion of Cyprus by Turkish military forces in 1974, looters stripped many of the region churches, removing an estimated 15,000 to 20,000 icons and several dozen major frescoes and mosaics, intending to sell them illegally on the antique market. The Church of Antiphonitis was among them. The walls with the two biblical episodes suffered major damages and big portions of their pictorial decoration were removed. Since the end of the 1990s, due to efforts of Cypriot authorities, more than 70 fragments of its frescoes returned from USA and Europe to the Byzantine Museum of Nicosia, where they are currently under conservation and restoration for future display. These were digitally documented through high-resolution ortophotos. The inner space of the church was documented by similar means, in order to virtually re-position the frescoes in their original locations. The virtual re-composition of the frescoes along the looted walls helped quantifying the missing parts, correctly re-locate virtually each fragment at its original position, obtain accurate colour information and prepare a digital musealisation product, to be included in the permanent exhibition display at the museum which will feature a 1:1 scale reproduction of the church walls.

Published: June 2016

Abstract. In recent years many earthquakes hit Italy and its Cultural Heritage. The topic of survey of buildings damaged by seismic events and their interpretation has become very relevant and involved many research groups and Italian Civil Protection. The damage survey has different roles: in the first stage, immediately after the emergency, the documentation is necessary for the shoring and protection of damaged structures (AEDES forms of Civil Protection). The aim of the second stage is the study and the documentation for the restoration, reconstruction and retrofitting of buildings. In this context, this study presents methods and instruments used in the survey of 24 churches in the province of Mantua, Lombardy, after the 2012 earthquake sequence. The paper examines the difficulties in surveying damaged buildings and presents the classification used to define, time by time, the most suitable survey approach in the field of Geomatics. In this classification, many aspects are taken into account, such as logistical and practical problems, safety conditions, time preserving methods, economic decisions, complexity of building and required results. The accurate documentation obtained as a three-dimensional architectural database allows for the observation and analysis of the damage, the definition of interpretative models and the development of intervention projects. Different results are obtained from the point cloud database: traditional 2D representations for architectural projects as well as 3D models for structural analysis or for the development of BIM.
THE PROCESS OF DIGITIZING OF OLD GLOBE
Authors: Ambrožová K. , Havrlanta J. , Talich M. , Böhm O.
Published: June 2016

Abstract. This paper describes the process of digitalization of old globes that brings with it the possibility to use globes in their digital form. Created digital models are available to the general public through modern technology in the Internet network. This gives an opportunity to study old globes located in various historical collections, and prevent damage of the originals. Another benefit of digitization is also a possibility of comparing different models both among themselves and with current map data by increasing the transparency of individual layers. Digitization is carried out using special device that allows digitizing globes with a diameter ranging from 5 cm to 120 cm. This device can be easily disassembled, and it is fully mobile therefore the globes can be digitized in the place of its storage. Image data of globe surface are acquired by digital camera firmly fastened to the device. Acquired image data are then georeferenced by using a method of complex adjustment. The last step of digitization is publication of the final models that is realized by two ways. The first option is in the form of 3D model through JavaScript library Cesium or Google Earth plug-in in the Web browser. The second option is as a georeferenced map using Tile Map Service.
INTEGRATED SURVEY FOR ARCHITECTURAL RESTORATION: A METHODOLOGICAL COMPARISON OF TWO CASE STUDIES

Published: June 2016

Abstract. A preliminary survey campaign is essential in projects of restoration, urban renewal, rebuilding or promotion of architectural heritage. Today several survey techniques allow full 3D object restitution and modelling that provides a richer description than simple 2D representations. However, the amount of data to collect increases dramatically and a trade-off between efficiency and productivity from one side and assuring accuracy and completeness of the results on the other must be found. Depending on the extent and the complexity of the task, a single technique or a combination of several ones might be employed. Especially when documentation at different scales and with different levels of detail are foreseen, the latter will likely be necessary. The paper describes two architectural surveys in Italy: the old village of Navelli (AQ), affected by the earthquake in 2009, and the two most relevant remains in Codiponte (MS), damaged by the earthquake in 2013, both in the context of a project of restoration and conservation. In both sites, a 3D survey was necessary to represent effectively the objects. An integrated survey campaign was performed in both cases, which consists of a GPS network as support for georeferencing, an aerial survey and a field survey made by laser scanner and close range photogrammetry. The two case studies, thanks to their peculiarities, can be taken as exemplar to wonder if the integration of different surveying techniques is today still mandatory or, considering the technical advances of each technology, it is in fact just optional.
THE REPRESENTATION OF CULTURAL HERITAGE FROM TRADITIONAL DRAWING TO 3D SURVEY: THE CASE STUDY OF CASAMARY’S ABBEY
Authors: Canciani M. , Saccone M.
Published: June 2016

Abstract. In 3D survey the aspects most discussed in the scientific community are those related to the acquisition of data from integrated survey (laser scanner, photogrammetric, topographic and traditional direct), rather than those relating to the interpretation of the data. Yet in the methods of traditional representation, the data interpretation, such as that of the philological reconstruction, constitutes the most important aspect. It is therefore essential in modern systems of survey and representation, filter the information acquired. In the system, based on the integrated survey that we have adopted, the 3D object, characterized by a cloud of georeferenced points, defined but their color values, defines the core of the elaboration. It allows to carry out targeted analysis, using section planes as a tool of selection and filtering data, comparable with those of traditional drawings. In the case study of the Abbey of Casamari (Veroli), one of the most important Cistercian Settlement in Italy, the survey made for an Agreement with the Ministry of Cultural Heritage and Activities and Tourism (MiBACT) and University of RomaTre, within the project "Accessment of the sismic safety of the state museum", the reference 3D model, consisting of the superposition and geo-references data from various surveys, is the tool with which yo develop representative models comparable to traditional ones. It provides the necessary spatial environment for drawing up plans and sections with a definition such as to develop thematic analysis related to phases of construction, state of deterioration and structural features.
A GEODATABASE FOR MULTISOURCE DATA APPLIED TO CULTURAL HERITAGE: THE CASE STUDY OF VILLA REVEDIN BOLASCO
Authors: Guarnieri A. , Masiero A. , Piragnolo M. , Pirotti F. , Vettore A.
Published: June 2016

Abstract. In this paper we present the results of the development of a Web-based archiving and documenting system aimed to the management of multisource and multitemporal data related to cultural heritage. As case study we selected the building complex of Villa Revedin Bolasco in Castefranco Veneto (Treviso, Italy) and its park. Buildings and park were built in XIX century after several restorations of the original XIV century area. The data management system relies on a geodatabase framework, in which different kinds of datasets were stored. More specifically, the geodatabase elements consist of historical information, documents, descriptions of artistic characteristics of the building and the park, in the form of text and images. In addition, we used also floorplans, sections and views of the outer facades of the building extracted by a TLS-based 3D model of the whole Villa. In order to manage and explore these rich dataset, we developed a geodatabase using PostgreSQL and PostGIS as spatial plugin. The Web-GIS platform, based on HTML5 and PHP programming languages, implements the NASA Web World Wind virtual globe, a 3D virtual globe we used to enable the navigation and interactive exploration of the park. Furthermore, through a specific timeline function, the user can explore the historical evolution of the building complex.
REMOTELY SENSED DATA FUSION IN MODERN AGE ARCHAEOLOGY AND MILITARY HISTORICAL RECONSTRUCTION
Authors: Juhász A. , Neuberger H.
Published: June 2016

Abstract. LiDAR technology has become one of the major remote sensing methods in the last few years. There are several areas, where the scanned 3D point clouds can be used very efficiently. In our study we review the potential applications of LiDAR data in military historical reconstruction. Obviously, the base of this kind of investigation must be the archive data, but it is an interesting challenge to integrate a cutting edge method into such tasks. The LiDAR technology can be very useful, especially in vegetation covered areas, where the conventional remote sensing technologies are mostly inefficient. We review two typical sample projects where we integrated LiDAR data in military historical GIS reconstruction. Finally, we summarize, how laser scanned data can support the different parts of reconstruction work and define the technological steps of LiDAR data processing.
A SEMI-AUTOMATED POINT CLOUD PROCESSING METHODOLOGY FOR 3D CULTURAL HERITAGE DOCUMENTATION
Authors: Kıvılcım C. Ö. , Duran Z.
Published: June 2016

Abstract. The preliminary phase in any architectural heritage project is to obtain metric measurements and documentation of the building and its individual elements. On the other hand, conventional measurement techniques require tremendous resources and lengthy project completion times for architectural surveys and 3D model production. Over the past two decades, the widespread use of laser scanning and digital photogrammetry have significantly altered the heritage documentation process. Furthermore, advances in these technologies have enabled robust data collection and reduced user workload for generating various levels of products, from single buildings to expansive cityscapes. More recently, the use of procedural modelling methods and BIM relevant applications for historic building documentation purposes has become an active area of research, however fully automated systems in cultural heritage documentation still remains open. In this paper, we present a semi-automated methodology, for 3D façade modelling of cultural heritage assets based on parametric and procedural modelling techniques and using airborne and terrestrial laser scanning data. We present the contribution of our methodology, which we implemented in an open source software environment using the example project of a 16th century early classical era Ottoman structure, Sinan the Architect’s Şehzade Mosque in Istanbul, Turkey.
3D MODELING OF COMPONENTS OF A GARDEN BY USING POINT CLOUD DATA
Authors: Kumazakia R. , Kunii Y.
Published: June 2016

Abstract. Laser measurement is currently applied to several tasks such as plumbing management, road investigation through mobile mapping systems, and elevation model utilization through airborne LiDAR. Effective laser measurement methods have been well-documented in civil engineering, but few attempts have been made to establish equally effective methods in landscape engineering. By using point cloud data acquired through laser measurement, the aesthetic landscaping of Japanese gardens can be enhanced. This study focuses on simple landscape simulations for pruning and rearranging trees as well as rearranging rocks, lanterns, and other garden features by using point cloud data. However, such simulations lack concreteness. Therefore, this study considers the construction of a library of garden features extracted from point cloud data. The library would serve as a resource for creating new gardens and simulating gardens prior to conducting repairs. Extracted garden features are imported as 3ds Max objects, and realistic 3D models are generated by using a material editor system. As further work toward the publication of a 3D model library, file formats for tree crowns and trunks should be adjusted. Moreover, reducing the size of created models is necessary. Models created using point cloud data are informative because simply shaped garden features such as trees are often seen in the 3D industry.
USE OF IMAGE BASED MODELLING FOR DOCUMENTATION OF INTRICATELY SHAPED OBJECTS
Authors: Marčiš M. , Barták P. , Valaška D. , Fraštia M. , Trhan O.
Published: June 2016

Abstract. In the documentation of cultural heritage, we can encounter three dimensional shapes and structures which are complicated to measure. Such objects are for example spiral staircases, timber roof trusses, historical furniture or folk costume where it is nearly impossible to effectively use the traditional surveying or the terrestrial laser scanning due to the shape of the object, its dimensions and the crowded environment. The actual methods of digital photogrammetry can be very helpful in such cases with the emphasis on the automated processing of the extensive image data. The created high resolution 3D models and 2D orthophotos are very important for the documentation of architectural elements and they can serve as an ideal base for the vectorization and 2D drawing documentation. This contribution wants to describe the various usage of image based modelling in specific interior spaces and specific objects. The advantages and disadvantages of the photogrammetric measurement of such objects in comparison to other surveying methods are reviewed.
ADAPTATION OF INDUSTRIAL HYPERSPECTRAL LINE SCANNER FOR ARCHAEOLOGICAL APPLICATIONS
Authors: Miljković V. , Gajski D.
Published: June 2016

Abstract. The spectral characteristic of the visible light reflected from any of archaeological artefact is the result of the interaction of its surface illuminated by incident light. Every particular surface depends on what material it is made of and/or which layers put on it has its spectral signature. Recent archaeometry recognises this information as very valuable data to extend present documentation of artefacts and as a new source for scientific exploration. However, the problem is having an appropriate hyperspectral imaging system available and adopted for applications in archaeology. In this paper, we present the new construction of the hyperspectral imaging system, made of industrial hyperspectral line scanner ImSpector V9 and CCD-sensor PixelView. The hyperspectral line scanner is calibrated geometrically, and hyperspectral data are geocoded and converted to the hyperspectral cube. The system abilities are evaluated for various archaeological artefacts made of different materials. Our experience in applications, visualisations, and interpretations of collected hyperspectral data are explored and presented.
NON-DESTRUCTIVE SURVEY OF ARCHAEOLOGICAL SITES USING AIRBORNE LASER SCANNING AND GEOPHYSICAL APPLICATIONS
Authors: Poloprutský Z. , Cejpová M. , Němcová J.
Published: June 2016

Abstract. This paper deals with the non-destructive documentation of the “Radkov” (Svitavy district, Czech Republic) archaeological site. ALS, GPR and land survey mapping will be used for the analysis. The fortified hilltop settlement "Radkov" is an immovable historical monument with preserved relics of anthropogenic origin in relief. Terrain reconnaissance can identify several accentuated objects on site. ALS enables identification of poorly recognizable archaeological objects and their contexture in the field. Geophysical survey enables defunct objects identification. These objects are hidden below the current ground surface and their layout is crucial. Land survey mapping provides technical support for ALS and GPR survey. It enables data georeferencing in geodetic reference systems. GIS can then be used for data analysis. M. Cejpová and J. Němcová have studied this site over a long period of time. In 2012 Radkov was surveyed using ALS in the project “The Research of Ancient Road in Southwest Moravia and East Bohemia”. Since 2015 the authors have been examining this site. This paper summarises the existing results of the work of these authors. The digital elevation model in the form of a grid (GDEM) with a resolution 1 m of 2012 was the basis for this work. In 2015 the survey net, terrain reconnaissance and GPR survey of two archaeological objects were done at the site. GDEM was compared with these datasets. All datasets were processed individually and its results were compared in ArcGIS. This work was supported by the Grant Agency of the CTU in Prague, grant No. SGS16/063/OHK1/1T/11.

Published: June 2016

Abstract. The exploitation of high quality 3D models for dissemination of archaeological heritage is currently an investigated topic, although Mobile Augmented Reality platforms for historical architecture are not available, allowing to develop low-cost pipelines for effective contents. The paper presents a virtual anastylosis, starting from historical sources and from 3D model based on TLS survey. Several efforts and outputs in augmented or immersive environments, exploiting this reconstruction, are discussed. The work demonstrates the feasibility of a 3D reconstruction approach for complex architectural shapes starting from point clouds and its AR/VR exploitation, allowing the superimposition with archaeological evidences. Major contributions consist in the presentation and the discussion of a pipeline starting from the virtual model, to its simplification showing several outcomes, comparing also the supported data qualities and advantages/disadvantages due to MAR and VR limitations.

Abstract. Sometimes it is difficult to represent “on paper" the existing reality of architectonic elements, depending on the complexity of his geometry, but not only in cases with complex geometries: non-relief surfaces, can need a “special planar format” for its graphical representation. Nowadays, there are a lot of methods to obtain tridimensional recovery of our Cultural Heritage with different ranges of the relationship accuracy / costs, even getting high accuracy using “low-cost” recovery methods as digital photogrammetry, which allow us easily to obtain a graphical representation “on paper”: ortho-images of different points of view. This can be useful for many purposes but, for others, an orthographic projection is not really very interesting. In non-site restoration tasks of frescoed vaults, a “planar format” representation in needed to see in true magnitude the paintings represented on the intrados vault, because of the general methodology used: gluing the fresco on a fabric, removing the fresco-fabric from the support, moving to laboratory, removing the fresco from the fabric, restoring the fresco, gluing back the restored fresco on another fabric, laying the restored fresco on the original location and removing the fabric. Because of this, many times, an unfolded model is needed, in a similar way a cylinder or cone can be unfolded, but in this case with a texture included: UV unwrapping. Unfold and fold-back processes, can be especially interesting in restoration field of frescoed vaults and domes at: chromatic recovery of paintings, reconstruction of partially missed geometries, transference of paintings on surfaces, etc.

Abstract. An orthoimage is one of the basic photogrammetric products used for architectural documentation of historical objects; recently, it has become a standard in such work. Considering the increasing popularity of photogrammetric techniques applied in the cultural heritage domain, this research examines the two most popular measuring technologies: terrestrial laser scanning, and automatic processing of digital photographs. The basic objective of the performed works presented in this paper was to optimize the quality of generated high-resolution orthoimages using integration of data acquired by a Z+F 5006 terrestrial laser scanner and a Canon EOS 5D Mark II digital camera. The subject was one of the walls of the “Blue Chamber” of the Museum of King Jan III’s Palace at Wilanów (Warsaw, Poland). The high-resolution images resulting from integration of the point clouds acquired by the different methods were analysed in detail with respect to geometric and radiometric correctness.
OBJECT DEFORMATIONS FROM IMAGE SILHOUETTES USING A KINEMATIC FINITE ELEMENT BEAM MODEL
Authors: Jepping C. , Luhmann T.
Published: June 2016

Abstract. In this paper a method is presented which allows the measurement of deflections and torsion by means of the silhouette of an object in images. The method is based on a finite element description of a beam. The benefit of this method is the determination of the deformation out of the silhouette of an object in images without the need of signalization. The presented method is tested against simulated data as well as against real objects in laboratory tests. As an outlook the presented method can be further modified. By combination with a laser scanner it seems to be possible to replace the CAD model of an object with the point clouds of one or more kinematic laser scans.
TOWARDS THE INFLUENCE OF A CAR WINDSHIELD ON DEPTH CALCULATION WITH A STEREO CAMERA SYSTEM
Authors: Hanel A. , Hoegner L. , Stilla U.
Published: June 2016

Abstract. Stereo camera systems in cars are often used to estimate the distance of other road users from the car. This information is important to improve road safety. Such camera systems are typically mounted behind the windshield of the car. In this contribution, the influence of the windshield on the estimated distance values is analyzed. An offline stereo camera calibration is performed with a moving planar calibration target. In a standard procedure bundle adjustment, the relative orientation of the cameras is estimated. The calibration is performed for the identical stereo camera system with and without a windshield in between. The base lengths are derived from the relative orientation in both cases and are compared. Distance values are calculated and analyzed. It can be shown, that the difference of the base length values in the two cases is highly significant. Resulting effects on the distance calculation up to a half meter occur.
FINE REGISTRATION OF KILO-STATION NETWORKS - A MODERN PROCEDURE FOR TERRESTRIAL LASER SCANNING DATA SETS
Authors: Hullo J.-F.
Published: June 2016

Abstract. We propose a complete methodology for the fine registration and referencing of kilo-station networks of terrestrial laser scanner data currently used for many valuable purposes such as 3D as-built reconstruction of Building Information Models (BIM) or industrial asbuilt mock-ups. This comprehensive target-based process aims to achieve the global tolerance below a few centimetres across a 3D network including more than 1,000 laser stations spread over 10 floors. This procedure is particularly valuable for 3D networks of indoor congested environments. In situ, the use of terrestrial laser scanners, the layout of the targets and the set-up of a topographic control network should comply with the expert methods specific to surveyors. Using parametric and reduced Gauss-Helmert models, the network is expressed as a set of functional constraints with a related stochastic model. During the post-processing phase inspired by geodesy methods, a robust cost function is minimised. At the scale of such a data set, the complexity of the 3D network is beyond comprehension. The surveyor, even an expert, must be supported, in his analysis, by digital and visual indicators. In addition to the standard indicators used for the adjustment methods, including Baarda’s reliability, we introduce spectral analysis tools of graph theory for identifying different types of errors or a lack of robustness of the system as well as in fine documenting the quality of the registration.

Abstract. Monocular vision-based lane departure warning system has been increasingly used in advanced driver assistance systems (ADAS). By the use of the lane mark detection and identification, we proposed an automatic and efficient camera calibration method for smart phones. At first, we can detect the lane marker feature in a perspective space and calculate edges of lane markers in image sequences. Second, because of the width of lane marker and road lane is fixed under the standard structural road environment, we can automatically build a transformation matrix between perspective space and 3D space and get a local map in vehicle coordinate system. In order to verify the validity of this method, we installed a smart phone in the ‘Tuzhi’ self-driving car of Wuhan University and recorded more than 100km image data on the road in Wuhan. According to the result, we can calculate the positions of lane markers which are accurate enough for the self-driving car to run smoothly on the road.
DEVELOPMENT OF A NEW LOW-COST INDOOR MAPPING SYSTEM – SYSTEM DESIGN, SYSTEM CALIBRATION AND FIRST RESULTS

Published: June 2016

Abstract. For mapping of building interiors various 2D and 3D indoor surveying systems are available today. These systems essentially differ from each other by price and accuracy as well as by the effort required for fieldwork and post-processing. The Laboratory for Photogrammetry & Laser Scanning of HafenCity University (HCU) Hamburg has developed, as part of an industrial project, a lowcost indoor mapping system, which enables systematic inventory mapping of interior facilities with low staffing requirements and reduced, measurable expenditure of time and effort. The modelling and evaluation of the recorded data take place later in the office. The indoor mapping system of HCU Hamburg consists of the following components: laser range finder, panorama head (pan-tilt-unit), single-board computer (Raspberry Pi) with digital camera and battery power supply. The camera is pre-calibrated in a photogrammetric test field under laboratory conditions. However, remaining systematic image errors are corrected simultaneously within the generation of the panorama image. Due to cost reasons the camera and laser range finder are not coaxially arranged on the panorama head. Therefore, eccentricity and alignment of the laser range finder against the camera must be determined in a system calibration. For the verification of the system accuracy and the system calibration, the laser points were determined from measurements with total stations. The differences to the reference were 4-5mm for individual coordinates.
