11. Operating AutoGeometry: Faceted display
11. OPERATING AUTOGEOMETRY: FACETED DISPLAY
About this chapter
The Faceted display AutoGeometry is available for systems having hard edged channel screens like multi facet screens where the
physical screen boundaries can be used as reference points.
The goal of AutoGeometry is to determine the position of the screen corners in relation to the panel of the corresponding projector (X
and Y projector pixel coordinates), where deviations between the captured and realigned state are returned to the Image Generator
in order to make corrections. This chapter describes how to capture this data.
Overview
• AutoGeometry Capture
See “R5977056 6 — API Com m ands f or XD S RACU Software” for the AutoGeom etry comm ands that can be
initiated through the API.
CAUTION: In order to use the camera functionality of the AutoAlignment Head, one should either boot the
MCU and s tay logged out of Windows or permanently stay logged in on Windows during usage of the Au-
toAlignment Head. A limitation of the camera d river m akes it inacc
essible after a Windows logoff event on the
MCU. One sh ould reboot o r re-login to be able to use the cam era functionality again after a Windows logoff.
11 .1 A utoGeometry Capture
AutoGeometry Capture
The AutoGeometry Capture function retrieves the X and Y projector pixel coordinates of the visible corners of each display channel.
During the capturing process, a sequence of patterns will be displayed, depending on the positioning data defined on the Positioning
page.
AutoGeometry Capture is to be run only when the camera position is defined for each projector channel corner on the Positioning
page. During Capturing process no stray light is allowed. All light on the screen other than the projector light must be eliminated.
AutoGeometry Capture process can be run for both standard channels or a Head-Up Display projector.
Make sure that the AutoGeometry position is defined for each projector channel corner in the selected group
whose coordinates need to be measu red.
By default, the patterns o n which the m easu remen ts for AutoGeometry are performed are generated in the
projectors. It is ho wever possible to use the AutoGeom etry IG testpatterns thro ugh API command s. S ee
“R59770566 — A PI Commands for XDS RACU Software”.
The best practice is to capture the Au toGeomet ry value for all the p rojectors in the selected group at o nce.
How to start the AutoGeometry capture process?
1. Open the AutoGeometry page.
