We present a non-rigid alignment algorithm for aligning
high-resolution range data in the presence of low-frequency
deformations, such as those caused by scanner
calibration error. Traditional iterative closest points
(ICP) algorithms, which rely on rigid-body alignment, fail
in these cases because the error appears as a non-rigid
warp in the data. Our algorithm combines the robustness
and efficiency of ICP with the expressiveness of thin-plate
splines to align high-resolution scanned data accurately,
such as scans from the Digital Michelangelo Project [The Digital Michelangelo Project: 3-D scanning of large statues]. This application is distinguished from previous uses of the
thin-plate spline by the fact that the resolution and size of
warping are several orders of magnitude smaller than the
extent of the mesh, thus requiring especially precise feature correspondence.
