Vision: what's state of the art in FRC?

[yash101]

What is the purpose? Do you want to process a handful of images at the beginning of the match, or do you want to continually process images and perform AI like pathfinding? Those questions are extremely important for answering many of your questions. The first option should not require more power than the RoboRIO offers. The second option would probably benefit from a coprocessor. These tiny boards can offer a lot of power, easily many times the available oomph of the RoboRIO.

Running OpenCV on the RoboRIO is far from realistic. The hard disk space is quite limited, and as it seems to me, there will be missing pieces of linux which will make it extremely difficult to compile all the dependencies of OpenCV.

Also, I think OpenCV can be a tad inefficient in general. I was running a small test and OpenCV's windows maxed out one of my system's cores (i3)!

I really think converting color spaces, thresholding and some of these relatively simple transformations should be much faster, especially because the formula should be constant.
