pr0ntools can be found at https://github.com/JohnDMcMaster/pr0ntools/

I also published a copy via PyPi for the heck of it but its probably out of date.

See Tutorial

pr0ntools has the following toolchain for image stitching:

• pr0nstitch: take in a list of .jpg's and an output .pto to produce a .pto with control points (features) between them. Expects row and col tagged images in. This makes stitching more accurate and much faster since the problem goes from O(n**2) to find control points to O(n) with large hints as to where it should be looking
• pr0nts: stitch an already optimized .pto file into tiles
• pr0nmap: create a Google Maps image from already existing tiles
• pr0npto: utilities to take care of some intermediate steps
