Any other teams considering an ODROID U board for on-robot image processing?
I came across this board yesterday, and am wondering if it will be viable for image processing. It has a quad core ARM CPU, and is very much like a Raspi or Cubieboard in usage.

Great! I'll suggest this board to my team.

We've gotten one and are experimenting with it. Right now our Odroid-U2 is configured with a 32GB Class 10 uSD, Ubuntu Linux, OpenCV, and a Logitech C615 webcam. We're going to experiment with that camera and the axis camera.
It is sort of fun that the only monitor which we have that has an HDMI port is the CAD workstation's 27" beast. |

Re: Any other teams considering an ODROID U board for on-robot image processing?
Here is an image that my vision programming team generated from using OpenCV under Ubuntu on an Odroid-U2. Programming language is C++ (g++ compiler).
This is actually a screenshot of the Odroid picking out the letters on a student t-shirt in real time from a video stream. Obviously not precisely what we need...but definitely showing the power of the Odroid and OpenCV. It was very impressive to watch this happen live on the screen.

Re: Any other teams considering an ODROID U board for on-robot image processing?
How much faster would this be than using image processing on the driver station? Ours has a 1s lag for some reason. I saw a video on youtube of someone's frisbee tracking program that had almost 0 lag, it was crazy!
And what are some of the pros to this compared to the driver staton? Will the latency times be lower and will it be faster or what? |

If you have no idea how long it takes to process an image, I'd encourage you to measure it and then ask the camera for about that many frames. That eliminates the problem since there is little need to skip and you can leave enough headroom to catch up if you do fall behind. You an also combine the two, skip and avoid asking for more images than you need in a given time period. Greg McKaskle |

Dial back the frame rate. At 30 fps, there's more than a half second of delay on our Dashboard image. At 10 fps, we get no noticeable lag.

A little late, but...
my team has on. We 3d printed a case for it that has a heat sync in the case. It runs my program at a surprising 25 fps (granted, I have been optimizing my program for the past 3 weeks now). It runs ubuntu 12.10 and I use the microsoft kinect. |

Re: Any other teams considering an ODROID U board for on-robot image processing?
How did you install OpenCV? The website's installation instructions references things which are pretty vague. Also (you don't have to answer this), how do you actually get the C-RIO to communicate with the board (i.e recieve commands/values and tell the robot to do something)?
