4.6 In Line Quality Control of Stamped Parts 
Applying a large number of single spot lasers projected 
onto a surface, MNS can map any deviation from the 
CAD model within a few seconds. 
5 CONCLUSIONS 
MNS is the only on-line photogrammetry based coordi- 
nate measurement system fulfilling the accuracy specifi- 
cations given by the automotive industry for car body 
measurements. This high accuracy, as well as the porta- 
bility of the system, makes it into a unique tool for a 
number of applications beyond the reach of present 
coordinate measurement systems.
