How did you install WebODM (docker, installer, etc.)?

both standalone on linux and lightning. linux version: WebODM 2.4.1

What's your browser and operating system? (Copy/paste the output of https://www.whatismybrowser.com/)

Edge 120 on Windows 10

What is the problem?

When processing a full DJI M3E Multispectral dataset, the RGB orthophoto is blue

How can we reproduce this? (What steps trigger the problem? What parameters are you using for processing? Include screenshots. If you are having issues processing a dataset, you must include a copy of your dataset uploaded on Dropbox, Google Drive or https://dronedb.app)

process these datasets to reproduce https://e38surveysolutions.com/blogs/news/mavic-3-multispectral-data https://www.pix4d.com/dji-mavic-3-multispectral-dataset/

Seems the same issue as #1445

danieldobosi commented 5 months ago

That was my first impression intially too, so I started another job to process only the Multispectral TIFF files without the JPG's and I got the same blue results: image

pierotofy commented 5 months ago

Yes, that's because ODM will currently drop the JPG images and only keep G, R, NIR and Re.

I'm working on a potential fix, I will share in the upcoming days..
