Introduction

• A problem of reconstruction of artifacts from a
  collection of fragments appears very important
  for archaeological studies. But it requires a
  tedious and laborious work.
• Purposes
• To relieve archaeologists from the tedious work
• To boost reassembling efficiency, join
  archaeologists intelligence.
• A computer aided and collaborative approach is
  required

Introduction

Data Acquisition

• Image-based 3D modeling
• Particularly, a commercial software PhotoModeller
  is used to create 3D models in our project
• PhotoModeller supports exporting various types
  data
• VRML 2.0 is a suitable type for 3D representation
  of fragments
• Curves are exported as line segments, then it can
  be used as the source of curve matching.

6
Matching Estimation

• 3D curve fitting is employed to find most similar
  pair of fragments
• Curves are represented by curvature and torsion
  string
• Strings are compared and computed to obtain
  matching scores that stand for the similarity of
  curves

7
Interactive and Collaborative Reconstruction

• Collaborative work trough Access Grid
• Access Grid Shared application
