From the study of it is 
that the results obtained from a typical 
close range application are compatible 
with the simulated ones given that the 
application 
pre-marked 
control-check points of the 
are natural points and not 
well defined points. 
4. CONCLUSIONS 
obtained in the described 
application using the ASTRI proved that 
this new low cost system is a possible 
alternative for application with low to 
medium accuracy requirements. Improve- 
ments may be acquired with  pre-marked 
control points and larger photo scales. 
The results 
  
    
The amateur cameras may be freely used 
when combined with a system such as  ASTRI 
The whole combination constitutes an ex- 
tremely cost effective solution, which 
easily brings Photogrammetry to the hands 
of even a non-expert.
