  annote = {In this paper we present a new efficient solution to the
    absolute pose problem for a camera with unknown focal length and
    radial distortion from four 2D-to-3D point correspondences. We
    propose to solve the problem separately for non-planar and for
    planar scenes.  By decomposing the problem into these two
    situations we obtain simpler and more efficient solver than the
    previously known general solver.  We demonstrate in synthetic and
    real experiments significant speedup as our new solvers are about
    40x (non-planar) and 160x (planar) faster than the general
    solver. Moreover, we show that our two solvers can be joined into
    a new general solver, which gives comparable or better results
    than the existing general solver for of most planar as well as
    non-planar scenes.},
