Quan : Affine Structure from Line Correspondences 3

| This paper presents a linear algorithm for recovering 3D aane shape and motion from line correspondences with uncalibrated aane cameras. The algorithm requires a minimum of seven line correspondences over three views. The key idea is the introduction of a one-dimensional projec-tive camera. This converts 3D aane reconstruction of \line directions" into 2D projective reconstruction of \points". In addition, a line-based factorisation method is also proposed to handle redundant views. Experimental results both on simulated and real image sequences validate the robustness and the accuracy of the algorithm.
