Getting Ready to Scan
Scanning Technique Guidelines
We highly recommend reading this section, before you start scanning in order to
ensure the best scanning technique for achieving optimal results.
This section describes the proper techniques for achieving the best scanning
results using the Imager:
Co-coverage
Both ends of the Imager (camera and projector) must have a clear line-of-
sight to the subject at all times. Video frames that do not contain the
projected pattern cannot be developed into 3D point-clouds. For
example, 3D data cannot be reconstructed from a video taken while the
projector is turned off or blocked.
Angles
Rotate the Imager around the object to cover it from all sides and
directions. Try to include shots where the Imager is parallel to the object’s
surfaces from all angles (for optimal accuracy). Avoid covering any facet
with only acute- angled shots.
Distance
Record specific objects from a distance of 1.0 m – 1.5 m (40” − 60”) for
the best accuracy.
Do not film at distances of less than 0.5 m (20”) or greater than 4 m
(13’).
For larger scenes, increase the range to 1.5 m (60”) or up to 2 m (80”)
to capture more of the scene per frame of video.
Speed
Move the Imager around the subject at a speed of approximately
50−75 cm/sec (20−30 inches/sec). This is similar to the recording speed
of a home camcorder. Moving too fast may cause motion blur, which
reduces the quality.
