Yeah, the scanner tutorial assumes actual images from a scanner, while I
assume you have a normal camera lens, but the procedure should be the
same. There are two projections to care about: input, which is whatever
your lens is (probably rectilinear), and output, where you can choose
freely, but you probably want rectilinear as well.
If things warp around the edges of your individual images, you may have
some lens parameters to optimise. That doesn't differ from any other pano.
There was a short thread on 15.2 where Thomas has explained the main
steps. If that doesn't help, you could post a few downsampled images so
we can see what's the matter.

https://hugin.sourceforge.io/tutorials/scans/en.shtml didn't say much - it
suggests "rectilinear" which gets warp-y as you go out towards the edges.

Is Hugin capable of this sort of thing or does it break the model?
I've got a downwards-facing camera taking pictures of a flat object (so I
don't have to worry as much about parallax). It moves in the X/Y
plane. A
bit like a scanner. I'd like to stitch the tiles into a single image. In
theory, this should be easy - right? Each image has an X/Y offset, and
maybe
a little rotation, but everything else is held constant.
The thing is, I'm not seeing a projection that works well with a flat
image,
all the projections are... well... projections. They assume a fixed
camera
that rotates.
Is there a way to do this?
Take a look at the tutorial on stitching flat scanned images, on the hugin
site.
It might be a help.
