One-sided Radial-Fundamental Matrix Estimation

Unknown Radial Distortion Centers in Multiple View Geometry Problems

The radial undistortion model proposed by Fitzgibbon and the radial fundamental matrix were early steps to extend classical epipolar geometry to distorted cameras. Later minimal solvers have been proposed to find relative pose and radial distortion, given point correspondences between images. However, a big drawback of all these approaches is that they require the distortion center to be exactl...

An easy non-iterative method for correcting lens radial distortion from point correspondences

This paper presents a new method for calibrating and correcting large radial distortion. It makes use of a number of image point correspondences from two views only. No knowledge of the scene structures, nor camera intrinsic parameters, is required. By using two singularity conditions, the method successfully decouples the estimation of the radial distortion from the estimation of fundamental m...

A Non-iterative Method for Correcting Lens Distortion from Nine Point Correspondences

یک روش کارآمد برای تخمین حالت مؤلفه اصلی و هارمونیکی در شبکه های توزیع شعاعی

In this paper an effective method for the purpose of state estimation of fundamental and harmonics signals in the radial power distribution network is presented. In Addition, the application development of this method to the network observability and data processing is considered and analyzed. One of the most advantages of this method is capability of bad data detection and process of them and ...
