4 CONCLUSION
We have succeeded this time to produce
DI-1000, which can create ortho-image
from the measurement on the site and PI-
2000, which can create stereo-image.
And in order to assess their capacity and
applicability we made experiment on a
road intersection and a cliff side.
The result was quite rewarding. We
could obtain a satisfactory ortho-image
through the measurement and
supplement measurement operation of
DI-1000. And by making stereo-
matching with the points, which DI-1000
and GPT had measured and PI-2000 had
manually measured, as the initial values,
we succeeded to measure a complex and
irregular object with high speed and accuracy.
Thus, we were able to produce reliable ortho-images and various other image presentations so useful for diverse
purposes.
We are highly convinced of having able to prove the great utility of our newly developed system.
Our objective now is to prove its capability by multiplying its practical applications.
