ABSTRACT
The two scanners used in this study are adopting
two different scanning technologies: pulsed-time-
of-flight-PTOF-(obtaining the distance to an
object by timing the round-trip traveling-time of
the laser) and amplitude modulated continuous
wave-AMCW-(comparing the phases of emitted
and received signals for indirect measurement of the
laser traveling time). These two types of scanners
are the two major-stream terrestrial scanners widely
used in the construction industry.
