when warping can be done on the projector
Selecting projector warping is best option, where warping done on the IG is not sufficient.
8.6.3.2 Defining AutoGeometry position: standard channels
Introduction
AutoGeometry is used to calculate the X and Y projector pixel coordinates of the required image corners of each channel in a display
system. This can be done by aiming your AutoAlignment Head camera to the required corner(s). For this purpose, AutoGeometry
positions must be defined to learn XDS RACU where to look for the corners.
Choose AutoGeometry position subtype Without Blend Zone if there is no overlap between channels or choose With Blend Zone
if there is overlap between channels.
It is good practice to include as much corners as possible in one position, however this depends upon the
channel size in the display. Both multiple corners of a single channel or corners of different channels are
allowed within a single AutoGeometry position.
Mechanically blocked the overshoot or stray light coming from one channel into the other channel.
AutoGeometry requires full colored test patterns. Remove any color filters from theprojector light path during
execution of AutoGeometry, including from the Head -Up Display.
A Head-up Display is not co nsidered as a standard channel.
Measuring corners in single channel setup
Consider a display system where you have a projected image consisting of one single channel. In this case four corners in total
need to be included in the set of positions to be defined.
