Detect if a camera angle changed

I have a fixed camera and I need to check if its position or orientation has been changed. I am trying to use OpenCV (calculating diiferencies between a reference image and a new one) for this, but I am pretty new to OpenCV (and image processing in general) but I am not really sure what specific algorithm would be the best to use for this, or how to interpret the results to find if the camera has been moved/rotated. Any ideas? Please help,

You can use Canny or HoughLinesP to find lines,From this you can get two lines,compare it.Maybe this will be effective in some simple background.if some object in your picture,try sift or other feature extractor,you can take features to find the relationship from two frames.

One way to do it would be to register the two frames to each other using affine image registration from openCV. From this you can extract the rotation and displacement difference between the two frames. Unfortunately this will only work well for in-plane rotations but I still think it is your best bet.

If you post some sample code and data I would be happy to take a look.
