3D-Messen groĂźer Volumen bzw. groĂźer Bauteile

Leitfaden zur optischen 3D-Messtechnik

GroĂźe Bauteile entstehen im Fahrzeugbau (PKWs und LKWs in der Automobilproduktion, Flugzeugrumpfschalen oder
Turbinenmodule im Flugzeugbau, Rahmen und Außenhaut an Schienenfahrzeugen), im Schiffbau, im Anlagenbau oder bei der Produktion von Energieerzeugungsanlagen (Windenergieanlagen, Großturbinen, usw.). An sie werden hohe Anforderungen hinsichtlich Maßhaltigkeit und Ausführungsqualität gestellt. Typische, sich daraus ergebene Messaufgaben sind das Prüfen geometrischer Merkmale in einem großen Messvolumen (z. B. Maß- und Formabweichungen über mehrere Meter) sowie das dimensionelle Erfassen einer lokalen Bauteilgeometrie oder das Prüfen eines lokalen Montagezustands in einem global registrierten Bauteilkoordinatensystem.
Dazu kommen Sensoren zum Einsatz, die nur in einem lokal begrenzten Messvolumen, typischerweise kleiner 1m, Bild und
Geometrieinformationen erfassen können. Da die Abmessungen der Großbauteile mehrere Meter bis mehrere zehn Meter
betragen, mĂĽssen die lokal erfassten PrĂĽfmerkmale fĂĽr die sich anschlieĂźende Auswertung in ein globales Koordinatensystem, ĂĽblicherweise das Bauteilkoordinatensystem, transformiert werden.

Journal of Electronic Imaging

Abstract.  Accurate recognition of airborne pollen taxa is crucial for understanding and treating allergic diseases which affect an important proportion of the world population. Modern computer vision techniques enable the detection of discriminant characteristics. Apertures are among the important characteristics which have not been adequately explored until now. A flexible method of detection, localization, and counting of apertures of different pollen taxa with varying appearances is proposed. Aperture description is based on primitive images following the bag-of-words strategy. A confidence map is estimated based on the classification of sampled regions. The method is designed to be extended modularly to new aperture types employing the same algorithm by building individual classifiers. The method was evaluated on the top five allergenic pollen taxa in Germany, and its robustness to unseen particles was verified.

COSCH e-Bulletin

The paper presents different forms of documentation of a Late Antique and Early Byzantine water-powered workshop and milling complex in what is commonly known as Terrace House 2 in Ephesos, Turkey. The entire complex was documented by means of 3D laser scanning in 2009 and 2010. Geometrical data were processed and used in the form of a point cloud in the archaeological analysis. Narrow parts, complex structures, and small rooms of the well-preserved feature were surveyed efficiently using a 3D laser scanner. Additionally, panoramic images were captured. They offered the possibility to colour the point cloud, thus helping to identify and understand the feature better in the model. The developed consistent 3D point cloud of the entire feature provided the spatial data for analyses, reconstructions and technical drawings, such as ground plots and sectional views for publications.
In order to address specific questions, e.g. to determine the course of the chute, or the size and position of the water-wheels, it was essential to be able to work with complete geometric data. For that purpose the data were exported from original files, using a free software plugin, and made usable in an internet browser. The interface is easy to operate and allows measurement and marking of 3D distances and coordinates of single points, within one scanner position. These can be saved and exchanged. In addition, using this technique a selection of the 3D data will be made available to the general user.

ISPRS Technical Commission V Symposium

This paper documents the formulation of an international, interdisciplinary study, on a concerted European level, to prepare an innovative, reliable, independent and global knowledge base facilitating the use of today’s and future optical measuring techniques for the documentation of  cultural heritage. Cultural heritage professionals, color engineers and scientists share similar goals for the documentation, curation, long-term preservation and representation of cultural heritage artifacts. Their focus is on accuracy in the digital capture and remediation of artefacts through a range of temporal, spatial and technical constraints. A shared vocabulary to interrogate these shared concerns will transform mutual understanding and facilitate an agreed movement forward in cultural heritage documentation here proposed in the work of the COST Action Color and Space in Cultural Heritage (COSCH). The goal is a model that captures the shared concerns of professionals for a standards-based solution with an organic Linked Data model. The knowledge representation proposed here invokes a GUI interface for non-expert users of capture technologies, facilitates, and formulates their engagement with key questions for the field.

5th International Conference, EuroMed 2014, Limassol, Cyprus, November 3-8

The paper introduces some key interdisciplinary questions concerning the development of optical measuring techniques and electronic imaging applied to documentation and presentation of artefacts, as identified through the work of Colour and Space in Cultural Heritage (, a trans-domain European Action (TD1201) in the area of Materials, Physics and Nanosciences (MPNS) supported, since 2013, by the European Cooperation in Science and Technology TD1201. Some 125 international researchers and professionals participate in COSCH activities which have been organised around six main subjects: (1) spectral object documentation; (2) spatial object documentation; (3) algorithms and procedures; (4) analysis and restoration of cultural heritage surfaces and objects; (5) visualisation of cultural heritage objects and its dissemination; and (6) the semantic development of the COSCH Knowledge Representation.

The Authors outline and illustrate the approaches adopted by COSCH. They indicate future work that is needed to resolve the identified scientific, technical and semantic questions, as well as challenges of interdisciplinary communication, to ensure a wider adoption of specialist technologies and enhanced standards in 3D documentation of material cultural heritage — being a basis for its understanding, conservation, restoration, long-term preservation, study, presentation and wide dissemination.


Millstones of Aswan red granite found on the island of Elephantine, Egypt.


S. Wefers,
F. Mangartz



In 2011, the millstones of Elephantine Island were documented. Elephantine belongs to the area of red granite at Aswan (the old city of Syene), which is mainly famous for its monumental building stones – e.g. the unfinished obelisk – but also provided a hard rock that served for making millstones. Therefore, it is not surprising that all the Elephantine millstones are made from red granite. There are signs of quarrying on Elephantine, but no special millstone extraction sites could be identified. However, the presence of roughouts within the documented millstones proves their production on the site, maybe also from thereabouts. Seven Olynthiantype top stones, of which two are roughouts and two are stones left in an early stage of work, were recorded – Olynthian-type lower stones have not been found. Amongst the rotating millstones, there is a type not yet described for Egypt: we call them pseudo-Pompeian-type millstones. Their cylindrical top stones reach up to 60 cm in diameter, amongst the five bell-shaped lower stones, there is only one roughout. For the reconstruction, we suggest a design similar to the German “Haltern-Rheingönheim” millstones. The pseudo-Pompeian-type millstones seem to date from Late Antique to early medieval times but could have been in use for a much longer period. Only one rotary quern was found on Elephantine. Two top stones of edge-runners served as mills for crushing olives and three huge granite beams were used as foundations for oil presses.
