hi. has any more work been done on the sensor calibration recently?
16:46
alexML
intracube: I'm currently trying to calibrate a PLR preset; I captured a flat-field timelapse (500 pictures at 0.1ms, 1ms, 10ms and PLR 10ms/0.1ms, from clipping point until nearly dark frame)
16:46
alexML
if you have any ideas about how to process this dataset, you are welcome
16:50
alexML
so, at each data point, I have 4 matching pictures, captured at (roughly) the same moment
16:52
alexML
I know nothing about how bright was each "scene", other than the assumption that non-PLR images might have a somewhat linear response
17:02
Napejts
are there any bigger channels than #model_design ?
17:04
intracube
alexML: hi. unfortunately I think a lot of this colour science is beyond my knowledge
17:04
intracube
alexML: have the RGB sensor filters been profiled?
17:04
intracube
(spectrally)

intracube
so you'd be able to determine the purity/outer reach of the gamut
17:05
intracube
and the exact overlap between the RGB channels
17:08
intracube
I didn't see any info on the Cmosis datasheets regarding the colour filtering though
17:13
Spirit532
there's no overlap
17:13
Spirit532
it's a bayer mask
17:14
Spirit532
RGGB if I recall
17:14
intracube
Spirit532: I mean spectral overlap
17:14
Spirit532
there should be none
17:14
intracube
eg: http://www.fredmiranda.com/forum/topic/1361634/1#12987007
17:14
Spirit532
oh that
17:14
intracube
Spirit532: I'd have thought there would need to be overlap or else some wavelengths wouldn't register at all :)
17:15
Spirit532
it's in the sheet
17:15
Spirit532
page 60

I like that they specify a manual soldering profile too...
17:16
intracube
Spirit532: ah, thanks
17:16
Spirit532
if you can't find something via a description
17:16
intracube
where is the full doc? I haven't seen it on thier site

Spirit532
first link online
17:16
Spirit532
not sure if it's the latest revision
17:17
intracube
thanks
17:18
intracube
ah, that document. I'm sure I've got a copy of that... somewhere
17:18
Spirit532
And I'm sitting here, developing a new method of PCB prototyping whilst watching the autorouter cry out in tears of sodomy over an impossible board
17:18
intracube
:)
17:19
Spirit532
well, impossible parameters moreso
17:19
Spirit532
I told it to break out quite a number of SOICs w/ a 0.65mm track & 0.5 clearance
17:20
Spirit532
it'd crush this board at 0.3/0.5 width/clearance
