Abstract

For stereo imaging, it is a general practice to use two cameras of same focal lengths, with their viewing axis normal to the line joining the camera centres. This paper analyses the result of difference in orientations and focal lengths of two arbitrary prespective viewing cameras, by deriving the epipolar lines and its correspoinding equations. This enables one to find the correspondence search space in terms of focal length accuracies as well as camera orientation parameteres. Relevant numerically simulated results are also given.
