OCV Tool Overview

The OCV tool performs optical character verification (OCV), a process for verifying that each character in a text area is the expected character in the expected location. The OCV tool tolerates variations in

lighting
image quality
font stroke width
character position, rotation, and scale

The OCV tool’s primary application is to verify date and lot codes printed on product labels, but you can use it with any vision application that requires verifying letters, numbers, or symbols.
