Loop Closure - Paracosm PX-80 Field Manual

Loop Closure:

What does it
mean?
A loop closure is when the
Paracosm SLAM software
recognizes a place that it's been
to before. When it recognizes the
same place, it looks to see if there
was significant drift between
those captured locations.
If there was significant drift, then
it closes the loop and corrects the
error throughout the entire scan.
If there is no significant drift, then
nothing happens.
