analogic or analytic.Moreover, it opens some 
interesting new aspects such as digital image 
processing, observing false color stereomodel, graphic 
and image superimposition, and digital surface model 
(DSM) automatic generation. 
(3) A electron microscope digital image 3D processing 
system can be developed as a subsystem of a mature 
and general digital photogrammetric processing 
system. But it has practical significance to design a 
special microcomputer-based electron microscope digital 
image 3D processing system, since mostusers of this 
system are those scientists and engineers whose tasks 
are to research or analyse electron microscope 
photographs instead of other types. 
(4) EM3DPS is just a fundamental system. 
SinceEM3DPS has been designed in the structure of 
modularity, the electron microscope users can develop 
more functions according to specific requirements in 
the application.
