What is the best way to acquire the image and process it is what we are looking for. Should we focus on Grip running on the Rio? Should we focus on maybe RaspberryPi? Can the code be integrated into the robot code using OpenCV?

It depends on how in depth you want to go. I believe there was some toying to get GRIP running on a co-processor on the robot, but I'm not sure if that ever turned into anything. We are using a raspberry pi to grab images from a usb camera, and process them there in openCV. We set up MJPG streamer on the pi to grab images, and then accessed them in OpenCV like they were from an axis camera, as we had latency problems accessing the camera directly. I will probably be posting our code with an explanation after I have a chance to do some more testing, as we have yet to actually mount our system on our bot and use it for auto aiming.
