We used vision tracking this season, but we want to port it to a Raspberry Pi and OpenCV.

I'm curious why people seem to want to use an IP camera or a USB camera with the PI. What's wrong with the Pi camera module?

I know that it has a bit of a "fish eye" issue, but that's correctable with camera calibration. From what I've read, USB cameras with the PI are significantly slower, but I haven't verified that myself, and I just read it on the internet, so take that for what it's worth
