Inner Surface Reconstruction of 3D Scanned Vessels

Stefan Spelitz

Abstract

We present an algorithm for reconstructing the inner geometry of polygonal models with one or more openings (e.g. vessels). Known inner surface parts act as constraints to be fulfilled as part of the resulting solution. The calculation is done in an iterative fashion in order to minimize the difference between expected and achieved object volume. The output is a closed manifold polygonal mesh suitable for calculating properties like its volumetric capacity or for manufacturing (e.g. 3D printing). The algorithm has been applied to 111 antique vessels to allow a comparative study of their filling volumes.
