# Epipolar geometry estimated using the matches from the calibration apparatus

If we use the matched points of the calibration apparatus to
compute the fundamental matrix, as you can try here, the result
is much more reasonable than that obtained with the classical
calibration terchnique. *However, if you click on a point in the
background, you will find that the epipolar line does not go
through the corresponding point in the other image.* The
estimated fundamental matrix is available HERE, which can be computed either by `image-matching` or `FMatrix`.
What follows is Java applet which illustrates the estimated
epipolar geometry. *By clicking in one of the two images, the
corresponding epipolar line of this point in the other image
will be shown.* (For better visualization, you'd better to
enlarge the height of your browser such that both images are
visible simultaneously.)
