4. CONCLUSIONS 
3D shape of a static object or to measure the deformations of an 
object undergoing some 3D surface model have been presented 
a binocular correlation-based stereovision technique.

In photogrammetric process, industrial cameras have been 
calibrated in the test field and used the industrial applications. 
Industrial digital cameras have more advantages than the other 
digital cameras. The sensors of the industrial cameras have 
been fixed to the camera body without any inclination. This is 
the main advantages of the industrial cameras. The other 
advantages is that CCD camera can be understood as a metric 
camera because of its solid CCD matrix. It is assumed that the 
lens is stably interconnected with the camera body and the focal 
length is fixed.

Differences between the results of LVDT and photogrammetric 
process are that interconnected with the rotations. The rotations 
of the point which has measured by LVDT (Linear Variable 
Differential Transducer) are affected to the coordinate directly. 
However, in photogrammetric process the least square matching 
from second image coordinates directly from the epipolar lines. 
This is the restriction in this measurement algorithm for stereo 
imaging. This handicap would be eliminated with third or more 
camera station in this algorithm.
