...It was later shown by the present author in Hartley (1993, 1994b) to be equally applicable to projective scene reconstruction from 13 lines in the uncalibrated case....

...This tensor may be computed linearly from a set of line correspondences in three images, and as shown previously in Hartley (1993, 1994b), leads to an algorithm for projective reconstruction from line correspondences in three views....

...These fundamental matrices have a very simple expression in terms of the camera matrices, as follows Hartley (1994): F12 = a4 × A; F13 = b4 × B (14) where notation such as a4 × A means the matrix made up by forming the vector product of a4 with each of the columns of A separately....

...The importance of this result is that it allows an amalgamation of the linear algorithms for points (Shashua, 1995) and for lines (Hartley, 1994b)....

...The previous algorithm published in Hartley (1994b) for retrieving the camera matrices, and hence projective structure, from the trifocal tensor was not very stable numerically....
