We propose an approach for estimating the relative pose between calibrated image pairs by jointly exploiting points, lines, and their coincidences in a hybrid manner.

We tackle the problem of estimating a Manhattan frame, i. e. three orthogonal vanishing points, and the unknown focal length of the camera, leveraging a prior vertical direction.

Moreover, we derive a new minimal solver for homography estimation, requiring only a single affine correspondence (AC) and a gravity prior.

The minimal case for reconstruction requires 13 points in 4 views for both the calibrated and uncalibrated cameras.

The hard minimal problems arise from relaxing the original geometric optimization problem into a minimal problem with many spurious solutions.

It is a particular variation of multibody structure from motion, which specializes to two objects only.
