dc.description.abstracten	We introduce a new hybrid minimal solver that admits combinations of radially-distorted conjugate translations and radially-distorted parallel lines from the common scene plane to jointly estimate lens undistortion and afﬁne rectiﬁcation. The solver is the ﬁrst to admit complementary geometric primitives for rectiﬁcation purposes. In addition, a novel solver admitting three pairs of imaged parallel scene lines for the same problem is introduced. The proposed solvers are used with the Manhattan scene assumption to auto-calibrate cameras from a single image. Thesolversaregeneratedusingelementarymethodsfromalgebraicgeometry. As a result, they are simple, fast and robust. The solvers are used in an adaptive sampling framework that favors the feature combinations that are most frequently consistent with accurate scene plane rectiﬁcations. Auto-calibrations are recovered from challenging images that have either a sparsity of scene lines or scene texture. The method is fully automatic.	uk
