Hey everybody,
I'm trying to get OCR to work but no luck so far.
I want to try the OCR function to read all 4 numbers in the attached image but whatever I try, the OCR-Result don't show me any number.
Anybody out here that can help me to get going with this? Any help would be appreciated.
Thanks in advance,

Lucky,
You will have to use very sharp lighting from the sides to highlight those particular numbers. Frontal lighting on very small depressions/elevations will not work reliably. You can see similar lighting adjustments when trying to identify coins:

One the lighting is corrected you can apply various modules to segment the edge components which would be a pre-filter to actual OCR.
