Abstract:Structured-light illumination is a process of
three-dimensional imaging
where a series of time-multiplexed, striped
patterns are projected onto a
target scene with the corresponding captured
images used to determine
surface shape according to the warping of the
projected patterns around the
target. In a real-time system, a high-speed
projector/camera pair is used
such that any surface motion is small over the
projected pattern sequence,
but regardless of acquisition speed, there are
always those pixels near the
edge of a moving surface that capture the
projected patterns on both fore-
and background surfaces. These edge pixels
then create unpredictable results
that typically require expensive
processing steps to remove, but in this
Letter, the authors introduce a
filtering process that identifies motion
artifacts based upon the discrete
Fourier transform applied to the time axis
of the captured pattern
sequence.
Thank you
