Abstract
In the conventional education and training of photogrammetry,
a stereo-mirror scope and a parallax measurement bar are used,
which has limitation to obtain precise orientation and
accuracy.
In the computer age, it becomes very easy to develop a low
cost digital photogrammetry system with' a similar performance
as an analytical plotter if a personal computer, a digitizing
table with two cursors attached to stereoscope and software
of bundle adjustment with selfcalibration are combined
together as shown in Figure.
In cooperation with TOPCON, the author has succeeded to
obtain a patent from European Patent Office for the above
system on June 27, 1989.
