Here is one for you. @pierotofy @smathermather can I use ODM to create an orthomosaic of a building facade that I have taken photos of. 73 images of the front of the image with side and front overlap flown manually.
I want to basically just combine all the photos into one ortho and get webodm to totally ignore gps data and just stitch based on likeness between each photo.
I remember seeing this and apparently forgot to respond: you could absolutely do this: you would need to create ground control points. See this blog post and it’s siblings:
Absolutely possible. I use ODM to model 60’ shoreline bluffs on Lake Erie. Manual flight with 100-200 photos works great. The orthophoto isn’t very useful (as you might expect), but the models come out great. The default settings usually work fine if there’s enough overlap, but I generally run the 3D Model or High Resolution presets.

@wcarroll14 I ran your photos and only got part of the facade. I’m guessing this is more or less the result you got as well? I realize this post is from several months ago, so it may no longer be relevant.
The following isn’t a capability of ODM, unfortunately: “totally ignore gps data and just stitch based on likeness between each photo”
ODM checks for common points in the photo, then builds a 3d model, then flattens it to create the ortho. Finding seams between the photos and combining to create a big mosaic photo is something you’d need to do in a different tool. I tried to run your photos in Microsoft Image Composite Editor and got an architecturally interesting result:
More overlap and less sky in your photos might help. Just a guess. If this sort of panorama is all you need, Microsoft ICE or Hugin is probably a better fit. It’s a much faster process, too.
