Our team used a beaglebone during competition season and tested out a raspberry pi at two off season events. Both of them work well enough, having a low frame-rate but fast enough to get back accurate data. The main problem with these boards if you don't get a high end board is the lack of fast enough USB drivers to allow for large or fast frame-rates from usb webcams. Even though using the network camera can get around this, pyopencv uses ffmpeg for network streaming of video which has a very slow connection and is a major bottleneck, iirc C and C++ implementation can get around this by using their own image acquisition functions. Take your video source into account when picking the board. Of course your best option is offloading processing to a fast Driver Station.
