DJI 4 Multispectral

I would like to ask you about some specific parameters of the DJI 4 Multispectral camera (FC6360 camera). Does ODM take into account:

  1. calibrated sunlight sensor value

  2. Vignetting data

  3. distortion calibration parameters.

I haven’t done a whole lot of testing with that DJI camera, so I’m unsure whether that information is pulled in. We mostly tested with https://docs.opendronemap.org/multispectral.html#hardware.

We do have experimental support for 1 and 2 see ODM/multispectral.py at master · OpenDroneMap/ODM · GitHub and ODM/multispectral.py at master · OpenDroneMap/ODM · GitHub.

3 doesn’t really apply because we compute distortion parameters via structure from motion.

Dear all, I would also like to support this question or request for feature. Does ODM’s feature “–radiometric-calibration” supports “camera+sun” parameter of DJI Phantom 4 Multispectral? If it helps, here is the document from DJI outlining the specs for the image calibration: https://dl.djicdn.com/downloads/p4-multispectral/20200717/P4_Multispectral_Image_Processing_Guide_EN.pdf
And another dataset form me to play with:
