Re: Finding where you are in the field
Vision tracking using Java this year will be more difficult than in the other languages, unfortunately. Unless there is an update released soon, not all of the NIVision capabilities useful for rectangle tracking have been wrapped by WPILibJ (whereas in C++, they are all available).

It is unfortunate that despite the supposed "equal" capabilities of each officially supported language, in 2012 there are very unequal capabilities when it comes to vision processing.

We are looking into offboard (Driver Station laptop or separate single board computer on the robot) solutions to vision processing, but these capabilities are very poorly documented at the moment. We have written/modified JavaCV/OpenCV code to reliably track the goals, and are now playing around to find a way to get that code to send back it's "answers" to the cRIO, using either NetworkTables or a separate socket interface.
