5 Conclusion 
The photogrammetric methods bring without a shadow of doubt 
an considerable new dimension in industrial metrology. The use 
of the various types of processes, and particularly the aspects of 
integration for a better definition of the adjustments, is most 
helpful for several reasons in mechanics, particularly in CADM 
(Computer-assisted Design and Manufacture). 
For the sample test described, one is interested in the precision 
of acquisition and in the approach of observation of the images 
of objects in a previously defined space to allow a construction 
of a prototype (scale model) and to envisage simulations 
(design) . The degree of precision reached will be modest for 
applications requiring a great exactitude, but this does not pose 
a problem as to the handling of equations of observations. 
The complementarity with other methods of measurements such 
as MMT is a good approach which can find applications in the 
comparison and inverse engineering.
