Abstract
We estimate the accuracy of a 3D-range scanner in terms of its
spatial frequency response. We determine a scanner's modulation
transfer function (MTF) in order to measure its frequency response.
A slanted edge is scanned from which we derive a superresolution
edge profile. Its Fourier transform is compared to the Fourier
transform of an ideal edge in order to determine the MTF of the
device. This allows us to determine how well small details can be
acquired by the 3D-scanner. We report the results of several
measurements with two scanners under various conditions.
