Quasi-Euclidean Epipolar Rectification
نویسنده
چکیده
The standard setup in reconstructing the three-dimensional geometry of a scene from a pair of stereo images is to have them rectified, in which case the apparent motion of points is horizontal. With pinhole cameras, it is always possible to find two homographies that rectify the images. The method of Fusiello and Irsara assumes that both cameras are the same with principal point at the center, but keeps the focal length as an unknown. The virtual rotations of the two cameras are then evaluated to minimize the vertical motion of points. Source Code C++ source code of the full pipeline (containing SIFT point detection and matching, ORSA, rectification) is provided on the IPOL web page of this article1.

Camera array image rectification and calibration for stereoscopic and autostereoscopic displays
This paper presents an image rectification method for an arbitrary number of views with aligned camera center. This paper also describes how to extend this method to easily perform a robust camera calibration. These two techniques can be used for stereoscopic rendering to enhance the perception comfort or for depth from stereo. In this paper, we first expose why epipolar geometry is not suited ...
متن کاملA super depth of field height measurement based on local disparity
A super depth of field height measurement method is proposed to measure the object height with the optical stereoscopic microscope. The quasi-Euclidean epipolar rectification algorithm is utilized on the original stereoimage to obtain rectified stereoimages and calibrate two camera parameters. Then, feature points are obtained by the SURF (speed up robust feature) algorithm and their correspond...
متن کاملMirror symmetry => 2-view stereo geometry
We address the problem of 3-D reconstruction from a single perspective view of a mirror symmetric scene. We establish the fundamental result that it is geometrically equivalent to observing the scene with two cameras, the cameras being symmetrical with respect to the unknown 3-D symmetry plane. All traditional tools of classical 2-view stereo can then be applied, and the concepts of fundamental...

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...
