I'll suggest that you to run the existing vision examples and try the vision processing on the roboRIO. The roboRIO is many times faster than the PI2 and doesn't require you to coordinate several processors, different implementations of network tables, etc. Once you have some experience with that, you can run a similar experiment on the PI2.

Also, keep in mind that fps is not necessarily a good measure of how well a vision system is working. Most of the time, it is a good idea to use the camera as a slow sensor and close the loop on trajectory or orientation using a different sensor.
