I have a series of images (around 60) that need to be merged into a singular very large image. The images were taken from screenshots of a much larger map and so they just need to be stitched back together into a singular large image for a very large output.
So far I've tried a few options, but they all seem panoramic-centric and thus they all do not merge quite right in that they leave artifacts (strange bends and so forth). Even Photoshop's Photomerge isn't working out (it actually hangs each time with some kind of an apparent bug that's been around since 2013).
What would be the preferred method of stitching such images together that are simply one big set of randomly offset tiles and don't have to account for lens distortions or color correction?
I'm thinking that there may even be a solution via ImageMagick or another open source tool, but since the images do not have direct offsets and were captured in a semi-random fashion simple tiling doesn't work.
This can be done visually rather easily, but it's lengthy and tedious... and this is actually a relatively small project. I have more than a dozen of these to do with more than 100 tiles each after I get this first one under my belt.
