Triangulation for Points on Lines
Triangulation consists in finding a 3D point reprojecting the best as possible onto corresponding image points. It is classical to minimize the reprojection error, which, in the pinhole camera model case, is nonlinear in the 3D point coordinates. We study the triangulation of points lying on a 3D line, which is a typical problem for Structure-FromMotion in man-made environments. We show that th...
متن کاملThe 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 کاملDelaunay Triangulation of Moving Points
Delaunay triangulation and its dual structure Voronoi diagram represent a multi-purpose data structures which are widely used in computational geometry. Using these structures for sets of moving data is also relatively well-known and the general approaches have already been discovered. This paper focuses on the rarely discussed problem computing of the topological events e.g. the exact times of...
