1. You probably should read the technical paper: On the Necessary Number and Optimum Location of Fiducial Marks in an Aerial Photographic Appearance http://stinet.dtic.mil/oai/oai?verb=getRecord&metadataPrefix=html&identifier=AD0783834
2. If you are asking which algorithm to use to align digital aerial photographs to make a map, then there are many. I don't think in most cases fiducial marks are necessary because actual features of the land act as registration points. You might have some trouble in places like desert where the scenery from one frame to the next seems identical to the human eye, but I suspect software can correct for that. There are many, many, many scientific papers written on this topic. Here is one about using subsequent frames of video to stitch together a panorama: http://www.springerlink.com/content/ngjh3xx2jh5u3bbc/ I suggest going to scholar.google.com and typing something like "image mosaicing algorithm."
