I am a complete novice at using the Raspberry Pi but I have a project that requires me to perform skeleton detection using an Xtion Pro (PrimeSense 3D sensor). I need to keep the Pi standalone. I have installed OpenNI2 and OpenCV 2.3.1. The sample programs for them work. First off, how do I configure OpenNI/OpenCV to work together. And then, how do I actually start programming? What do I have to use? What libraries should I add?
