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.
