Small LB camera demo, how I check the repeatability.
The values for X and Y I have found by testing and averaging the values afterwards. Interestingly, there is almost no margin of error on X but a small deviation on Y. It could be inaccurate testing procedure or just camera lens which should almost function as a fisheye.
But with 0.2mm deviation in a few places of my work area, I can live with it. 
, and when super accuracy is needed I fine tune anyway.
