G'day Ulhas,
        I've been using it for a while now. To get decent results you need to
be
using a camera fixed to the tester so that there is no relative movement
between them. I take a sequence of around 20 pictures starting with an
offset of around 7mm inside the ROC to around 13mm outside the ROC. You
need to make sure that when the pictures are loaded in to the program that
you also put in the correct offset for each picture. Also, are you
adjusting the position of the area to be measured for each photo. If there
has been any movement between the camera and tester this will show up as
misalignment in the measuring area.

Cheers
