Yet Another Vision Processing Thread

How do you intend to coordinate the image processing over the multiple nodes? Do you already have a multi-node OpenCV library? As far as I know,
OpenCV doesn't have an MPI-enabled version, only multithreaded.

Well, 1706 loves using the Kinect, and they say that they will use 3 cameras. I guess that there will be one for each camera and one for the kinect. Maybe one of them does the data manipulation, or maybe it is done on the cRIO.

By the way, Hunter, how do you prevent your ODROIDs from corrupting from the rapid power-down? Do you have a special mechanism to shut down each node? Also, which converter are you using to power the Kinect? I don't think it would be wise to connect it directly to the battery/PDB, etc. You'd need some 12v-12v converter to eliminate the voltage drops/spikes!

As for your query of multi-noded, I think you are misunderstanding what he is doing, having a computer for each of the 3-4 cameras onboard the bot. Hunter will probably just use regular UDP sockets, as he said in his post. Either one UDP connection per XU can be used to the cRIO, or maybe there can be a master XU, that communicates with each slave XU, processed what they see, and beams the info to the cRIO!

However, I think it is still overkill to have more than 2 onboard computers, except the cRIO!
