TRAFFIC LIGHT DETECTION USING CONIC SECTION GEOMETRY [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 Traffic lights detection and their state recognition is a crucial task that autonomous vehicles must reliably fulfill. Despite scientific endeavors, it still is an open problem due to the variations of traffic lights and their perception in image form ...

Exact conic section arc elements in 2D and 2.5D FEM using a coordinate transformation [PDF]
IET Microwaves, Antennas & Propagation, 2021 This study introduces the conic section arc elements in 2D and 2.5D finite element method (FEM). Elements are obtained by deforming an edge in a standard triangular element through a coordinate transformation.

A sylvester theorem for conic sections [PDF]
Discrete & Computational Geometry, 1988 As a generalization of the Sylvester theorem for a set of n-points in the Euclidean or projective plane it is proved: if S is a finite set of points in the plane and no conic contains all points of S, then S determines a conic which contains exactly 5 points of S.

A novel camera calibration method for fish-eye lenses using line features [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 In this paper, a novel method for the fish-eye lens calibration is presented. The method required only a 2D calibration plane containing straight lines i.e., checker board pattern without a priori knowing the poses of camera with respect to the ...

Equivariant adjusted least squares estimator in two-line fitting model
Modern Stochastics: Theory and Applications, 2016 We consider the two-line fitting problem. True points lie on two straight lines and are observed with Gaussian perturbations. For each observed point, it is not known on which line the corresponding true point lies.
