Unknown Radial Distortion Centers in Multiple View Geometry Problems
Brito, José Henrique; Angst, Roland; Köser, Kevin; Zach, Christopher; Branco, Pedro; Ferreira, Manuel João; Pollefeys, MarcThe 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 exactly known. In this ...
One-sided Radial-Fundamental Matrix Estimation
Brito, José Henrique; Zach, Christopher; Köser, Kevin; Ferreira, Manuel; Pollefeys, MarcFor modern consumer cameras often approximate calibration data is available, making applications such as 3D reconstruction or photo registration easier as compared to the pure uncalibrated setting. In this paper we address the setting with calibrateduncalibrated image pairs: for one image intrinsic parameters are assumed to be known, whereas the second view has unknown distortion and calibration parameters.
