In this paper we present a new approach to robust 3D rigid body motion estimation and scene structure recovery using an epipolar corridor. In comparison to traditional two stage approaches we do not rely on independent establishment of feature point correspondences and subsequent computation of 3D motion parameters, but iteratively feed the motion parameters back to the point correspondence est...

In this paper, we present results of a comparative study on disparity analysis of convergent stereo systems. If the epipolar geometry is known, disparity analysis can be performed by computing the disparity along the epipolar line in the original views. Using a parallel stereo algorithm, the convergent views have to be rectified in order to have horizontal and parallel epipolar lines. In this s...

Many traditional stereo correspondence methods emphasized on utilizing epipolar constraint and ignored the information embedded in inter-epipolar lines. Actually some researchers have already proposed several grid-based algorithms for fully utilizing information embodied in both intraand inter-epipolar lines. Though their performances are greatly improved, they are very time-consuming. The new ...

Knowledge of the epipolar lines is of utmost importance in stereo vision since they describe the geometrical relationship between the world points and their projections on the imaging sensors. In this paper we propose a two-phase method to solve the epipolar geometry. Firstly, we extract the corners from a stereo pair and their correspondences are determined by imposing a number of matching con...

This paper presents the 3-D terrain reconstruction with aerial photography. The results of 3-D reconstruction using intensity-based matching and hybrid intensity-based and epipolar geometry approach matching are shown and compared. The intensity-based image matching uses maximum normalized cross correlation to find the displacement vector between two images. This method can overcome the effect ...

We take a fresh look at the problem of removing occluders in an image using inpainting. We examine a geometric method that utilizes a second image of the scene from a different viewpoint, to identify the occluded objects. We recover the missing intensities by using the geometric relationship between corresponding points in the two images. The relationship is generally specified by the “epipolar...

Binocular stereo is the process of obtaining depth information from a pair of left and right views of a scene. We present a new approach to compute the disparity map by solving a global optimization problem that models occlusions, discontinuities, and epipolar-line interactions. In the model, geometric constraints require every disparity discontinuity along the epipolar line in one eye to alway...

In this study, a new reconstruction approach is proposed for the line segments that are nearly-aligned (≤ 10o) with the epipolar line. The method manipulates the redundancy inherent in line pair-relations to generate artificial 3D point entities and utilize those entities during the estimation process to improve the height values of the reconstructed line segments. The best point entities for t...

Epipolar geometry between two images is normally computed by matching feature points between the images. When not enough feature points can be found, e.g. when the camera viewpoints vary greatly, epipolar geometry can be computed from video sequences showing moving objects visible in the two videos. We present a temporal signature for lines: a binary temporal sequence, indicating for each frame...
