stitch the images together (sift,orb) and apply a perspective transform.
if the images are uniform enough in style you can then probably crop them all at once with mask coordinates.
opencv/imagemagick will handle all of it.
if the images aren't uniform enough to crop them all at once, consider the use of a 'lazy susan' style vertical rotisserie, take all the photos from the same plane, easy post-processing.
