InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
Now, I know everyone else in this thread so far is ignoring your question and looking for alternatives, but since I've given you at least an answer, I'm going to suggest that instead of all that, you give Greenshot a try. It's a great screenshot software and it has a plugin for OCR. It might just do what you want with that plugin.
I think OpenCV is probably not the right application for what you're trying to do. You might try Tesseract OCR. In my experience OCR can be great at recognition when it's based on a crisp screenshot (usually it starts to struggle with scanned/photographed images).
