MediaLab at the European Researchers’ Night event

renlogoweb
MediaLab participated in the European Researchers’ Night event as part of the Athena Research Centre’s science and technology exhibition at the NCSR Demokritos. Fortunately the weather was great and the event was really crowded till midnight!

MediaLab’s exhibition theme was “Three-dimensional (3D) digital recording and printing: application to Cultural Heritage” and was briefly described as follows:

Digital recording of objects (or digitisation or scanning) in 3 dimensions is now a widespread practice that enables us complete visual recording of the objects of our world. The digital copies that 3D digitisation produces give us the opportunity of examining the objects from any desired angles, surpassing viewing a conventional picture that simply attaches an angle.
Particularly in the cultural heritage domain, 3D digitisation has been applied with great success to accurately record the geometry and colour of objects or monuments with multiple objectives: taking a snapshot of the current situation (visual documentation), promoting the study, restoration, education, dissemination and replication even production of real world copies with 3D printing.
MediaLab shows in this event how is currently feasible to capture in 3D objects of cultural value with photographic techniques, to present them to the Internet or on 3D displays and to reproduce them with 3D printing.

Here is a gallery of photos of MediaLab’s exhibition at the event:

3D digital cultural heritage A to Z

3D digital cultural heritage begins its life with 3D digitisation as part of a complete 3D recording approach and completes with the 3D applications and reproduction. 3D physical reproduction has gained momentum in the recent years as 3D printing technologies are becoming more and more accessible, mainly due to the reduction of cost both in hardware and in consumables used for printing.
Recently our lab acquired one such 3D printing system, the CubeX by 3D Systems. With this system our lab has now completed the puzzle of 3D digital cultural heritage, covering all aspects involved. With an Arius 3D laser scanning system, a customised structured light scanner based on the David 3D scanning system, a shape from silhouette scanning system and a Structure-From-Motion-Dense Multi-View 3D Reconstruction method with a turntable, along with an Optech Ilris 3D time-of-flight laser scanning system for large structures and open spaces, we are able to cover a diversity of 3D digitisation projects. With a long experience in data structures, cultural documentation and work for Europeana we are able to support any cultural documentation project. Our even longer experience in multimedia applications for cultural heritage in many forms and platforms covers numerous possibilities for digital delivery, scientific study, education and entertainment. Now with the addition of the CubeX 3D printing system we are able to cover the aspect of physical reproduction.

Our newly acquired CubeX system characteristics in brief:
Z axis resolution:
0.100mm (0.004” / 100 microns)
X-Y resolution:
+/- 1% of object dimension or +/- 0.2mm (0.008” / 200 microns) whichever is greater
Maximum build size:
275mm (w) x 265mm (l) x 240mm (h) or 10.75” x 10.75” x 9.5”

Here are a few draft 3D printed models from our previous work on monument digitisation:

Invited talks at AUTH seminar

Anestis Koutsoudis and George Pavlidis participated in the Seminar “Diagnostic techniques in the science of artworks curation” organized by the Crossdisciplinary Postgraduade Programme “Protection, Conservation and Restoration of Cultural Monuments” of the Aristotle University of Thessaloniki, held 17th-19th Feb. 2012.

This included invited talks at Aristotle University of Thessaloniki and a visit at the Multimedia Department of the Athena Research Center in Xanthi.

Here is the seminar program (greek).
Here is a simplified PDF version Dr. Koutsoudis’ talk (greek) and a simplified PDF version of Dr. Pavlidis’ talk (english).

Here are a couple of photos from the 3D technologies demonstration @ the Multimedia Department.
