Radiometric Calibration of DJI P4 Multispectral Images

Can opendronemap do radiometric calibration of DJI P4 Multispectral images?

It should. If not, share a dataset for the developers to test?

Thank you! I have some raw images in a Google Drive folder I could share.

Not sure if the share is on here, please let me know. But, the .tif images are of the multispectral bands that need to be radiometrically calibrated. The .jpg is the rgb image

The .tif images are in the 100m folder.

Can you also share a few details of how are you processing them? (All at once? Just the tiffs?) Did you tweak any settings?

Im very new to opendronemap as am considering to purchase a DJI P4 Multispectral only if can do orthometric maps and radiometric calibration free.

As am new, I started simple with just the rapid orthometric (all else default). I tried all images, then just a set of 5 images, then just 5 RGB, then just 5 .tiff same band and all gaive the same error.

I had another set of 6 .jpg from esri from a mavic and it created a generic rapid othromosaic (all else default) just fine. My goal in opendronemap is to forest make an orthomosaic map of all images (can be a small subset) and the conduct a radiometric calibration. I saw that in 2019 someone also sent a sent of DJI P4 Multispectral images wanted to do a radiometric calibration. That member of the community send the band widths correct in that string. Thank you!

Just the .tifs and still get the error?

I haven’t had time to look at this yet; I’m hoping to find some time in the upcoming weeks. :pray:

OK, thanks! I havent heard from other users if had success or not. Will check regularly.

Sorry to bother, but to help me trouble shoot are there other files opendronemap may be expectiving besides the .tif images? For example is it looking for a CAM, CSV, TXT with camera specs for example that might be causing the images? I was going to start by ensuring everything was in the folder it is expecting. Thanks!

Nop, should just work™ with the images.
