Your question seems to exceed the scope of this community. The Q&A community can help you answer questions about the OpenCV library, but it won't comment on complete applications. Specific questions are welcome.

OpenCV can certainly be used to solve a part of your problem - it will interact with USB cameras on Raspberry Pi, and the Pi can display video or interact with remote desktop. The specifics of this, and any processing, CSV files, and networks, are really up to the application.

Are you able to do programming? There are many examples of displaying live video from a camera in the OpenCV source code samples area, and many online tutorials too. Check out opencv.org, use a search engine with your question, maybe pick up a book on opencv programming, and give it a go!
