Using a webcam, I will be capturing frames of an object of known size. The object is rectangular in shape. I would like to be able to determine my position in space relative to the object.

The object which I will be looking at has key features that I know how to identify to get the 4 corners of the rectangle. The points will be distorted based on my location and I'd like to be able to figure out where I am relative to the object from doing some sort of transformation.

How do I go about doing this? It is for a robotics project running on a Raspberry Pi so performance is somewhat important and I don't need pinpoint accuracy.

Welcome to OpenCV! The tutorial you want is called Real Time pose estimation of a textured object. There all all kinds of useful tutorials, examples, and documentation at that site. Give them a read, try some out, and if you still don't understand you'll be able to ask much better questions.
