How to rotate all my measurements of an object to a single reference line fixed in the object.

Hello all I have a motor tooth which i am using for imaging. I used shape drive camera system to measure the tooth and analyse it in matlab. The problem is i have to move the tooth several times and hence cannot manipulate the same point from two different measurements. How do I fix a reference in my object and ensure that all the measurements are translated to this reference right before by analysis in matlab? Is there a translation matrix available which can be applied commonly to most cases? would be happy to have help as this is very new for me.

I don't know what a "motor tooth" is or what a "shape drive camera" is. And I don't know the layout or components in your system. Can you give a diagram of the rig, and a sample image that it creates?

Hello Snehalatha,
Can you share more details - like a sample image, code etc. ?
I assume you have to find the gear axle point as a reference, and use a MATLAB function from Image processing toolbox to find your affine transform the works for you.
See, http://www.mathworks.com/help/vision/geometric-transformations.html and the link http://www.mathworks.com/help/images/ref/affine2d-class.html

Sorry I'm not able to give you more detailed inputs beyond my initial suggestions.
