   Adventures in stereo photogrammetry..
  Hey-I'm attempting to generate pixel displacement maps for a set of stereo images with NO user input or projected grid/pattern on the subject..lots of dark areas, focus issues, etc.I've found lots of info, mostly GIS-related, nothing exceedingly helpful..I've gotten over the "basics" of the problem and can generate reasonable depth maps from 'good' stereo images (no solid areas, lots of detail), but the process is far from perfect and I dion't want to re-invent too many wheels..I know John Schultz and maybe a few others around here have dealt with things like this before, I was hoping someone might have some suggestions, links, etc.I'm probably going to purchase a book or 2 (found a few on Amazon that look promising), if anyone can recommend anything I would appreciate it..Thanks in advance for anyone who can pitch in :)-MM
