On the Probabilistic Epipolar Geometry
In this paper, we are going to answer the following question: assuming that we have estimates for the epipolar geometry and its uncertainty between two views, how probable it is that a new, independent point pair will satisfy the true epipolar geometry and be, in this sense, a feasible candidate correspondence pair? If we knew the true fundamental matrix, the answer would be trivial but in real...
متن کاملOn the Epipolar Geometry in Stereo Vision
In this paper we are interested in the calculation of the equation governing pairs of epipolar lines for unregistered images, i.e. when the image acquisition parameters are unknown or no calibration object is available. First we do a thorough analysis of the mathematics required to nd the epipolar line equations in the classical sense. Thereafter we show that for a broad class of stereo images ...
متن کامل3D Reconstruction Based on Epipolar Geometry
In this paper, we propose a new method for 3D reconstruction from three cameras based on the projective geometry. If the subject is just synthesizing images from new viewpoint, 3D shape reconstruction in Euclidean space is not required, and projective reconstruction gives enough information to synthesize new viewpoint images. This means that full calibration is not needed but recovery of epipol...
متن کاملCheirality in Epipolar Geometry
The image points in two images satisfy epipolar constraint. However, not all sets of points satisfying epipolar constraint correspond to any real geometry because there can exist no cameras and scene points projecting to given image points such that all image points have positive depth. Using the cheirality theory due to Hartley and previous work on oriented projective geometry, we give necessa...
متن کاملIs Epipolar Geometry Necessary?
We examine and contrast the projective properties of two simple 3D configurations. The first consists of six points, four of which are coplanar. We prove that epipolar geometry and the essential matrix can be recovered uniquely for this structure and give a constructive algorithm for this. The second configuration has four coplanar points and a single non-coplanar line. In this case it is not p...
