Abstract
The iterative closest point (ICP) algorithm is a
popular method for modeling 3D objects from range data. The classical
ICP algorithm rests on a rigid surface assumption. Building on recent
work on nonrigid object models, this paper presents an ICP
algorithm capable of modeling nonrigid objects, where individual scans
may be subject to local deformations. We describe an integrated
mathematical framework for simultaneously registering scans and
recovering the surface configuration. To tackle the resulting
high-dimensional optimization problems, we introduce a hierarchical
method that first matches a coarse skeleton of scan points, then
adapts local scan patches. The approach is implemented for a mobile
robot capable of acquiring 3D models of objects.
