Para-catadioptric Camera Auto-calibration from Epipolar Geometry
Original language description
We present a method for a para-catadioptric camera auto-calibration from point correspondences in two views based on the epipolar constraint. Besides rigidity, no assumptions about the scene are made (e.g. presence of a calibration object). The method leads to a closed form solution - to a polynomial eigenvalue problem and therefore no iterative minimizing process has to be used. The closed form solution allows to apply a 9-point RANSAC robust estimation technique and thus use automatically establishedpoint correspondences contaminated by mismatches. As a result of the calibration method, the calibrated camera, the estimated essential matrix, and the outliers in point matches are obtained. We demonstrate our method in experiments with commercially available parabolic mirror. Moreover, we show that the para-catadioptric camera model can be used in RANSAC to solve correspondence problem for a larger class of catadioptric cameras.
