6. CONCLUSION 
Technology is moving on all fronts with the potential to make 
photogrammetric image processing a reality; in particular real-time video 
systems for photogrammetric control of dynamic processes, and also systems 
for measuring, altering and analysing photo-based data via video windows. 
Not only can traditional concepts be improved upon, but entirely new ones 
are possible in ways that cannot yet be fully imagined.
