Hello, I use a device to measure the reflectance from 344 to 1045
wavelength,
How could I convert these measured data into Radiance RGB, and how could I
calculate the overall reflectance from the measurement?
I try to use weights of RGB channels in Radiance, but which wavelength out
of 344 - 1045 should I select for each channel?
Note that you have to decide the number of wavelengths ahead of time, and they must be evenly spaced.
I've arbitrarily set the overall Y value to 0.5, but of course you set it to what you need. I can't help you with that part.
Cheers,
-Greg

I have been using mgfilt to convert from spectrally resolved reflectance to rgb.
