Chilean configuration of conics, lines and points

چکیده
Using the theory of rational elliptic fibrations, we construct and discuss a one parameter family configurations $12$ conics $9$ points in projective plane that realizes an abstract configuration $(12_6,9_8)$. This is analogous to famous Hesse lines forming $(12_3,9_4)$. We also show any Halphen fibration index $2$ with four triangular singular fibers arises from such conics.

The projective reconstruction of points, lines, quadrics, plane conics and degenerate quadrics using uncalibrated cameras
In this paper we present an algorithm for the simultaneous projective reconstruction of points, lines, quadrics, plane conics and degenerate quadrics using Bundle Adjustment. In contrast, most existing work on projective reconstruction focuses mainly on one type of primitive. Furthermore, for the reconstruction of quadrics (both full-rank and degenerate) and plane conics, a novel algorithm for ...
متن کاملFitting conics to paracatadioptric projections of lines
The paracatadioptric camera is one of the most popular panoramic systems currently available in the market. It provides a wide field of view by combining a parabolic shaped mirror with a camera inducing an orthographic projection. Previous work proved that the paracatadioptric projection of a line is a conic curve, and that the sensor can be fully calibrated from the image of three or more line...
متن کاملThe Intersection Conics of Six Straight Lines
We investigate and visualize the manifold M of planes that intersect six straight lines of real projective three space in points of a conic section. It is dual to the apex-locus of the cones of second order that have six given tangents. In general M is algebraic of dimension two and class eight. It has 30 single and six double lines. We consider special cases, derive an algebraic equation of th...
متن کاملAlgorithms for projecting points onto conics
We study the problem of projecting 2D points onto quadratic curves (ellipses, hyperbolas, parabolas). We investigate various projection algorithms focusing on those that are mathematically proven to produce (or converge to) correct results in all cases. Our tests demonstrate that thosemaybe still unfit for practical use due to large computational errors. We present two new algorithms that are n...
متن کاملParameter and Configuration Analysis for Non-linear Pose Estimation with Points and Lines
In markerless model-based tracking approaches image features as points or straight lines are used to estimate the pose. We introduce an analysis of parametrizations of the pose data as well as of error measurements between 2D image features and 3D model data. Further, we give a review of critical geometrical configurations as they can appear on the input data. From these results the best parame...
