Target Collection Guidance
3. TARGET-FREE SCANNING SETUP
Working principle:
• By adopting our built-in independent
photogrammetry in MARVELSCAN, we need to
take photos for scale bar firstly to ensure the
accuracy.
• After all the photos of the scale bar are token, we
will take photos of other places from this scale bar
and make sure to cover all targets in the pre-
calibrated room.
