If you can live without the curve of the wall, I would do this: - In a drawing program like gimp, create a line drawing of a stripe with sections having the same aspect ratio as the individual images on the wall - imagine a ladder put down horizontal with rungs upright - Mask the individual normal shots so that there is some of the left and right neighbouring image visible; enough to let the blending software create an invisible blend. - 'pin' the four corners of each image to the corresponding points on your skeleton drawing (the ladder) - use the ladder drawing as reference and optimize the other images for r, p, y, x, y and z. If the otimization fails, you could try adding line control points along the ladder's lines; in my experience with stitching mosaics from handheld shots this has always helped getting the optimization to work and achieving a good result. - leave the placement of the seams to enblend; the curvature might be slight enough not to create too much parallactic error This process might be less work than processing each individual image to be perfectly normal and of the right size and then mosaicing them together. And making a trial with just a few images won't cost you too much time.
