WebbTo get the overall error, we add up these errors. we don't take a simple arithmetic mean, but use an RMS of these errors. There are many scientific reasons for this, but my … WebbThe matrix of intrinsic parameters does not depend on the scene viewed. So, once estimated, it can be re-used as long as the focal length is fixed (in case of zoom lens). The joint rotation-translation matrix [R t] is called a matrix of extrinsic parameters.
