Can I process scanned negatives with WebODM?

Lupo

I have a set of old scanned images from the public archive of our national surveying service. I was able to reconstruct these image with very early versions of ODM, but as of now, it fails at the openmvs DensifyPointCloud step.

The images I use can be downloaded as tiffs, which includes the full scan of the negativ. I'm cropping to images to the marks, convert them to JPG and inject exif for the Make, Model, and focal length, and I also created a cameras.json file.

I goes past the matching (opensfm), but it always fails at the openmvs DensifyPointCloud command. I'm attached my console output.

I can also share the images if someone wants to give it a try.

Btw, this is the source of the photos: https://www.fentrol.hu/hu/legifoto/115395

I'd try passing fast-orthophoto to skip the densification entirely
