After looking into a few of the vision solutions (briefly for each), it sounds like OpenCV on a daughter board is the most popular. However, I would like to know the pros and cons of the three "main" solutions: OpenCV, NI Vision, and RoboRealm.
- Which has your team used in the past?
- Which worked best?
- Which is the best for beginners in vision?
- Which one is more accurate?
I'm finding that RoboRealm is awesome to use! And quite simple. The only down-side (a pretty big one), is if we want good results, we would need an onboard laptop to run it.
I've played around with OpenCV very briefly and the first thing I've noticed is that there are very few tutorials out there for FRC specific tasks (past challenges, etc.) It seems very "learn-by-yourself".
We've used NI's Vision Assistant before, but we didn't end up using it. We didn't really explore it that much.
Finally, to leave off, I know that GRIP is coming soon, and I've played around the Alpha stage, and it seems pretty legit! What I don't know is how it will be used in FRC. Will it be a script that runs on the RoboRIO or Daughter-board? Does it run on a laptop with NetworkTables? They say they will release the final version "in time for kickoff", so maybe we just wait until then.
Anyway, to make a long post short: we want to start vision, and I, as the mentor, have played around with all of them at least for a little bit, and I would like to know what other teams do.
Thanks,
Joe
