In a binocular vision system, the two cameras are identical (i.e., their parameters are the same). The position vector of the right camera relative to the left camera is (10.0, 0.0, 0.0) (cm) while there is no change of orientation between these two cameras. Given the coordinates (v=20, u=30) of a pixel in the image of the left camera, what is the equation of Epipolar line in the image of the right camera?
