EXPERT PROJECTOR ALIGNMENT SOFTWARE
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.

Accurate
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.
Reference Points
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.
AutoAlign
After one source has been aligned, B
technology automatically adjusts the other sources
to obtain optimal geometry, edge matching and
convergence. This automated alignment process results
in a precise matching of adjacent channels in the
blend areas. Remote access is possible through a local
network.

is also a great help in performing a quick
UTO
LIGN
touch-up to maintain optimal multi-channel
geometry and convergence (including on green).
