Abstract| This paper presents a linear algorithm for recovering 3D a ne shape and motion from line correspondences with uncalibrated a ne cameras. The algorithm requires a minimum of seven line correspondences over three views. The key idea is the introduction of a one-dimensional projective camera. This converts 3D a ne reconstruction of line directions" into 2D projective reconstruction of points". In addition, a line-based factorisation method is also proposed to handle redundant views.
