Loop-closing: the process of correcting small tracking errors so that areas that are recorded more than
once in a single scan are properly positioned with respect to all the frames in the scan.
Registration: the process of positioning one or more scans so that points created from the same objects
are aligned with each other. (This is similar to the process of creating a large panorama from a collection
of smaller images.) If markers or targets are present in the scan, software can usually register scans
automatically—otherwise you must register them manually (also known as “placing” the scans).
Marker: an artificial target consisting of a special printed symbol that you can place in the scanning area
to help SCENE software register scans. Markers are especially helpful when you want to register a
Freestyle2 scan with a Focus
S
scan. For more information, see “Working with Markers” on page 48.
Point cloud: a 3D representation of an area or object made of millions of points created from one scan or
from several registered scans.
