I am creating an interface for a pulse duplicator. Part of this involves measuring the viscosity and inputing the value as a user input. Our requirement is to automatically incorporate viscosity. One possibility is to use a viscometer with an output however, we do not have one so our other option is to use a webcam to take photos of the screen and use optical character recognition to detect the value. I was wondering if there is a way to do this on Labview and if I could get possible assistance on that. The viscometer can display a maximum of 4 numbers. Thank you

I have never done it in LabVIEW, but I know there are some dll packages out there for OCR in C++. You could easily use them in LabVIEW.

Hi F.N,
You can easily do OCR in LabVIEW.
If you have Vision Development Module (VDM) installed in LabVIEW you should see the following OCR examples:
You can also do OCR from within Vision Builder for Automated Inspection (VBAI), or from within the Vision Assistant in LabVIEW.
I am sure you can find more information and OCR examples if you search ni.com.
