Hi,
I’m trying to use dispread to characterize a projector that’s part of a procam
system used for 3D surface scanning. The projector and camera both point at the
(white) floor, which is the stage where the object-to-be-scanned is placed. I’m
using a ColorMunki Photo to do the characterization. In addition to its normal
“reflection/transmission” hole on its bottom the CM has a “telephoto” hole on
its side (covered by a lens), and an “illuminance” hole on it’s top (covered
with a white diffuser). I know can use the -p flag with dispread and the CM in
the telephoto position to measure the light reflected off the floor/stage, but
it seems like it would be better if I could use the CM with the sensor in the
illuminance position and just place the CM on the floor/stage in the
projector’s FOV. The dispread documentation lists a -a flag for “ambient” mode,
but when I try to use this (with the CM in the illuminance position, the
software complains that “the sensor is in the wrong position”.
Is there some way for me to do what I’m proposing using Argyll and the CM?

Thanks in advance for any help.
