An effort towards heritage preservation

Introduction

• An approach of digitally mapping of geometry of
  sculpture is unique in our country.
• Information Technology in India has come a long
  way during last decade but its applications are
  yet to reach different areas of our society and
  one such area is heritage preservation.
• Sculpture in any museum or in art gallery is the
  heart of the cultural-heritage of a country.

Contd

• It is always found that cultural-heritage is in
  constant danger due to environmental aging and
  man made disasters.
• So a new need has been felt for the documentation
  and obtaining the geometrical models in this
  field.
• Advancement of new Scanning Technologies combined
  with advanced Reverse Engg. tools and Rapid
  Prototyping has offered us an opportunity to do
  this.
• Info-Sculpture project is an effort of
  IIT-Kanpur towards this direction.

4
Objective

• To record and archive the morphological features
  of heritage artifacts from the past culture,
• Process these features using modern software
  tools and to create a knowledge based information
  system,
• Exploring the potential of 3D vision for
  application in heritage or as input to virtual
  reality environment, and
• Geometric modeling for reconstruction and
  regeneration of artifacts.

Kausambi School of Art Department of Ancient
History, Allahabad University

• Kausambi was the capital of Vamsa and the scene
  of several important events in the Buddha's life.
  It has one of Asoka's pillar and a little further
  on the ruins of the Ghositarama, first built
  during the Buddha's lifetime. The huge ancient
  ramparts of the city though now all in ruins are
  also interesting.
• Department of Ancient History, Allahabad
  University, has an extensive collection of the
  minor antiquities found at Kosambi.

Mathura Museum

• The museum enjoys an enviable position among
  the museums of India.The rich collection of art
  preserved in the galleries of this museum,
  furnishes Indian cultural ethos and aesthetic
  excellence.
• Mathura museum is situated in Uttar Pradesh,
  150 Kms from New Delhi.

Methodology

• Point cloud capturing using digital optical
  scanner
• Point cloud processing Alignment,
  polygonization, hole filling, healing, etc,
• Prototyping using Rapid prototyping technology

Effect on Society

• The database of artifacts in digital form can be
  used in future modification work and replication.
• The technology under study will allow artists,
  sculptors, archaeologists, and researchers to
  view, analyze, and even reproduce artifacts
  digitally.
• The models thus created can form archives, which
  could be manipulated at any time to view, edit or
  fabricate.

21
Contd

• The future generations will have the records in
  digital form which is not subject to environment
  decay and vulnerable for deterioration as
  original sculpture is and thus it would be a
  permanent record in years to come.
• The work of this kind will be immensely helpful
  to the researchers in history and archeology now
  and in future.

Research issues

• How do you store 1000 Giga Bytes?
• If we take cost Rs. 100 per GB
• Total cost to store, let us say 1000 GB will
  be
• 1000 GB Rs 100 per GB
• Rs. 1,00,000
• And no library can afford to spend so much
  money for single
• work. So it is proposed that 3D data must
  be stored centrally with Government aid.

23
Contd

• How should the 3-D work be catalogued?
• In case of 2D Images indexing may be done by
  catalogue
  
• containing thumbnail images. But in case of
  3D,thumbnails
• should be interactive allowing the library
  user to examine the
• work from all the angles.

24
Contd

• Can bytes live longer than marbles?
• In case of 2-D works the images can be
  printed on paper at
• high resolution. In the event the digital
  archive becomes un-
• readable, it can be re-constructed.
• 3-D models have no natural printed
  representation. RP technology
• could be used to make physical replica but
  cost of such
• replica is high and size of large
  prototype is limited also.Thus it
• is important to preserve model digitally .

25
Contd

• 3D digital watermarking
• There is small growing body of literature on
  3D digital
• watermarking as proposed for 2D images.

26
Contd

• Piracy detection
• If we have technology that will search for
  specific 3D
• models on the web and 3D watermarking
  technique is
• available, piracy for 3D models can then be
  detected.
