Barco’s Projector Alignment Tool
For easy and fast alignment
of complex multi-screen
projection systems to their
maximum capabilities, Barco
has developed its own
proprietary dedicated
software.
With an intuitive user
interface, Barco’s Polaris
software is driven by
multi-
pipe, multi-channel image
generators
to calculate and
generate user-specified pre-
distorted test patterns.

automatically adjusts

to obtain optimal geometry, edge matching and
convergence. This automated alignment process results
in a precise matching of a
djacent channels in the
blend areas
. Remote access is possible through a local
network.

is also a great help in performing a quick

Expert Alignment Software
The user enters the dimensions and shape of
the screen (flat, cylindrical, spherical,
toroidal, dome-shaped, conical) and
Polaris
calculates and generates the
pre-distorted geometry, gray scale
and color alignment patterns.
Camera settings and parameters for
each display channel can be specified in
coordinates or as field-of-view angles,
either symmetrical or asymmetrical.
When applicable,
patterns can be saved
independently
from the
graphics configuration of
the image generator.
Accurate
Reference Points
To enable the alignment of several projectors onto a
multi-channel display,
accurate reference points
must be
marked on the screen structure
.
To achieve the highest level of accuracy possible, Barco
has developed its own procedures and corresponding
hardware.
