Re: Is the crio powerful enough?
The cRIO is powerful enough so that a few trig functions make absolutely no difference. We used a couple dozen of them for our drive routine with no noticeable slow-down at all. Using them in the vision routine should be no different. The main thing that will be slow is image processing, which is mostly affected by the camera resolution.
In addition, I imagine that the existing trig functions are already highly optimized for real-time applications, as that's what the cRIO is for. The cRIO has a floating point processor, so that should work pretty well.
Also, in my experience, one camera is good enough for range finding, provided you know the physical dimensions of the target, which has been the case in the last few games.
