It might be more like a computer vision question.
Assuming you have an essential matrix E for a stereo system,
I would like to know the geometric interpretation of u, s, v' in term of the stereo system (e.g. epipole, baseline, ...),
once you decompose E using SVD.
I tried to dig in to the geometric interpretation of SVD, and it seems that u, v' are the rotation matrix, while s are the scale. Though I cannot really related them to the geometric of the stereo system.
Thank you. Thu, 12 Feb 2015 02:33:35 -0600http://answers.opencv.org/question/55031/single-value-decomposition-of-an-essential-matrix/
