Is it possible to add a option to dial in manually the conversion factor pixels to mm?
Most of the time in our lab there is no scale or grid in the image to obtain the correct displacement of the object.
Thanks,

I can think of two ways to do that:
If you add a line anywhere and do "display measure", it's going to be in pixels. So if you know your scaling factor you could compute the true size of that line and input it manually in the calibration dialog.
The second way is to open and modify the KVA file directly (You have to "save" it at least once first). Look for the node Calibration > CalibrationLine > Scale. This value is the number of real world units per pixel.
