5. FUTURE DEVELOPMENTS
All described software is still under development. This is
an advantage, because all user requests and also critical
functions in education and training can be considered in
the last upgrade.
5.1 Functionality
Based on user requests the projective transformation
BPROTRA will be converted to MS-Windows. During the
education there were some problems fixed with the
display tool VIEWPL. The new version will be extended
with functions for subpixel measurements, new zoom and
roam functions and on-line rectification methods.
The on-scren digitizing tool ONSCRE will contain
additional functions for object attribute definitions and
accumulating mosaicing functions.
5.2 Conclusions
Today it is always advisable to develop individual
software for image processing and digital
photogrammetry. Only then it is possible to include all
features a user requests. A growing modular software will
lead educational projects as well as research projects to
good results.
Of course, there exist a lot of commercial software
installations for operational production, but with standard
software not all problems can be solved.
A toolbox which can grow with the requirements of a
project is the best solution. This task can be covered by
individual software and by flexible processing systems,
which are open for the integration of additional own
modules.
