stereoscope, while the visopret 20 uses a 
reflecting stereoscope. They are equipped with 
a two-way illumination mechnism, which allows 
measurements using film and prints. 
4.2.10 Comparision of Systems with 
Stereoscopic Image Measurement 
Comparing the above mentioned systems, one can 
see that they all differ from each other quit a 
bit. It is therefore difficult to consider one 
system better than the other, Nevertheless the 
subdivision into stereocomparators, image- 
space- and object-space plotters should be 
noted. Especially the evaluation of 
contourlines is done in the simplest way with 
an object-space-plotter. In general the choice 
of a system depends on the application one has 
to do. But all systems have one thing in 
common. Due to their low prices they make 
photogrammetry affordable for people who are 
not able to pay the price of a standard 
analytical plotter. In Table 4.2.1 they are 
listed in alphabetical order with some 
important characteristics. The prices include 
hardware and basic software to run the systems.
