Most easiest way is to use NI OCR from NI Vision (the OCR example is shipped together). If you haven't  NI VDM, then alternatively you can achieve this with OpenCV (but you will need to integrate OpenCV into LabVIEW, which non-trivial for beginners). What I would like to recommend is to learn basics of the machine vision - obviously you shall be able to open or acquire an image, then perform kind of segmentation to locate letters and digits, may be registration to locate the board, also some thresholding, etc. If you feel free with image processing, then OCR will be not very complicated.

If you will follow NI OCR, then I would like to recommend to use Vision Assistance first to train/adjust and test your characters before start with coding in LabVIEW:
