This project has been funded with support from the European Commission‘s CIP ICT PSP programme
Click to edit Master 1tle style Introduc1on
! Funded under the European Commission’s ICT Policy Support Programme
! Built on the results of CARARE and 3D-‐COFORM EU
projects ! 16 partners from across Europe (11 countries) with
relevant exper1se in 3D modelling and digi1za1on.
Click to edit Master 1tle style The 3D-‐ICONS Project
! 3D-‐ICONS provides Europeana with 3D models of architectural and archaeological monuments of remarkable cultural importance (World Heritage)
! Purpose of the project: to produce around 4000 accurate 3D models, to be processed into a simpler form in order to be visualised also on low end personal computers and on the web.
! Challenge for Cultural Heritage sector to bring their 3D models used for scien1fic & research purposes into the public domain
Click to edit Master 1tle style What is Europeana? h<p://www.europeana.eu
! A huge database of informa1on about digital content
(metadata) held by European cultural heritage ins1tu1ons
– Funded by the European Commission – Supplied by a range of Best Prac1ces and other Pilot Projects as well as
directly by (larger) ins1tu1ons
! Catalyst for new content services
– Europeana services and tools, standards, Linked Open Data, … – Hackathons – new content-‐based apps – Europeana Research, next stage
! Source of on-‐line exhibi1ons (engaging the public) ! Network of cultural heritage organisa1ons and exper1se
Click to edit Master 1tle style Guidelines:
! The 3D-‐ICONS project exploits exis1ng tools and methodologies and integrates them in a complete supply chain of 3D digi1sa1on.
! Creates a complete pipeline which covers all technical and logis1c aspects to create 3D models of cultural heritage objects with a variety of digi1sa1on techniques.

Click to edit Master 1tle style 3D Data Capture Techniques:
Non-‐invasive
and
Non-‐destruc0ve
Non-‐contact systems (means that they do not require physical contact with poten1ally fragile artefacts and structures):
-‐ ac1ve
-‐ passive
Click to edit Master 1tle style 3D Data Capture Techniques:
l Short Range Techniques
-‐ Laser Triangula1on (LT)
-‐ Structured Light (SL)
l Long & Mid Range Techniques
-‐ Time of Flight (TOF)
-‐ Phase shig laser scanning (PS)
l Mul1 Scale Image based Techniques
-‐ Tradi1onal Photogrammetry
-‐ Semi Automated Image Based Methods
Click to edit Master 1tle style Post Processing of 3D Content: • A sequence of steps that result in the
direct improvement of acquired 3D data and its transforma1on into visually enriched geometric representa1ons.
• It allows the crea1on of mul1ple 3D
models star1ng from the same gathered data according to the desired applica1on, level of detail and other addi1onal criteria.
• The results are 3D geometric
representa1ons accompanied by complementary 2D media, which are the digital assets ready to be converted (or embedded) into the final web publishing formats.
Click to edit Master 1tle style Post Processing of 3D Content: Processing of point clouds data: involves cleaning and the alignment phases. Processing mesh data: transforma1on of point cloud data into a surface of triangular
meshes. Mesh Cleaning: filling holes, remove spikes, unreferenced ver1ces, and non-‐manifold edges. Mesh Simplifica1on: reduce the amount of data required to describe the surface of an
object while retaining the geometrical quality of the 3D model. Mesh retopologisa1on: generate a simpler version of the original dense model, by u1lising
the original topology as a suppor1ve underlying layer. Texture mapping: topological enhancement of low complexity geometry with special 2D
relief maps, that can carry high frequency informa1on about detailed topological features.
Click to edit Master 1tle style Post Processing of 3D Content:
• Digital restora1on: -‐ Reconstruc1on of missing details based on the predic1on of their shape • Hypothe1cal reconstruc1on:
-‐ Modeling based on addi1onal sources -‐ Valida1on by a range of different experts -‐ Document reconstruc1on process and uncertain1es
Click to edit Master 1tle style 3D Publishing Methodology:
Op1mal delivery and display of rich and complex 3D assets online.
-‐ 3D PDF
-‐ HTML5/WebGL Solu1ons
-‐ Unity -‐ Serious Games Solu1ons
-‐ Pseudo-‐3D (ObjectVR) solu1ons
-‐ 3DHOP (3D Heritage Online Presenter)
→ 3D Streaming
Click to edit Master 1tle style Metadata: The metadata provides key informa1on and
context data to five key areas: • It describes in detail the artefact or monument and
its provenance
• It describes in detail the digital representa1on of the artefact or monument and its online loca1on
• It provides informa1on on technical methods u1lised in the digi1sa1on and modelling of heritage objects
• It provides informa1on on the access, licensing and reuse of the created 3D models and any associated digital content
• It enables the search and discovery of content through the mapping of metadata based on the Europeana Data Model (EDM)
Click to edit Master 1tle style Licensing & IPR Considera1ons:
In order for the effec1ve sharing and reuse of 3D content of heritage objects a common framework is required.
