Thank you Matt and Diego,
I will look into those. In the meanwhile, could either of you, or anyone else, explain the problems, if any, in simply "georeferencing" the images to the pixel coordinate space by assigning the calibration-derived coordinates of the fiducials, in ArcMap for instance, to the fiducials and exporting a rectified image? Is that basically the process in interior orientation? Although, automating that process for many photos, I presume, would require some kind of image recognition algorithm to find the fiducial marks?
On the other hand, I just ran some old photos though PS after only specifying the focal length and got much better results, maybe good enough. Perhaps that's all the pre-processing I have to do; I would have to run some tests.
