Abstract : We prove that 3D affine reconstruction of lines with uncalibrated affine cameras is subject to a two way ambiguity. The key idea is to convert 3D affine reconstruction of "lines" into 2D projective reconstruction of "points". Then, the ambiguity of 2D projective reconstruction is analyzed by using the full tensorial representation of three uncalibrated 1D views.
