Commentary


The Vivid 910 scanner from Konica Minolta [
16] uses
a single
camera and laser stripe, and acquires
3D data
using
triangulation.


This scanner is not
designed specifically
for
faces as
the subject
must remain motionless during
that time
or a poor scan will
result.


There are
three different
zoom lenses available and an automatic
focus system
that allows scanning at a wide variety
of distances
from the camera (there is a tradeoff
between image
resolution and
standoff
)


It is
somewhat sensitive
to lighting conditions, but generally
operates well
indoors away from sunlight
.


Hence, It’s an excellent accuracy device, but can improve more
based on its cost of $40,000.
