The correspondence problem in stereo vision is to calculate matches between pixels (points) or features (e.g., lines) in stereo images. The method of calculating these matches over an entire stereo image pair usually depends upon the application for which the resulting depth information will be used. Functional minimization and dynamic programming are two widely used techniques for selecting ma...

considered the case in which the images are in the same imaging plane and the optical axes of the two images are parallel. The triangulation error is inversely proportional to the product of baseline x focal length. At a given focal length, a wider baseline reduces triangulation error but increases both geometric and photometric distortions in images which in turn makes matching of these images...

We explore the geometric and algebraic relations that exist between correspondences of points and lines in an arbitrary number of images. We propose to use the formalism of the GrassmannCayley algebra as the simplest way to make both geometric and algebraic statements in a very synthetic and e ective way (i.e. allowing actual computation if needed). We have a fairly complete picture of the situ...

In this paper, the geometric relationship between mosaic images for concentric panorama acquired by slit cameras along circular paths is considered. A concentric epipolar constraint is derived for mosaic images. It is shown how the concentric epipolar constraint can be used to calibrate the slit camera using point correspondences in two mosaic images. The concentric epipolar constraint is furth...

In this paper, a new line matching approach for high-resolution array remote sensing images is presented. This establishes the correspondence of straight lines on two by combining multiple constraints. Firstly, three geometric constraints, epipolar, direction and point-line relationship, are used in turn to reduce number candidates. After this, similarity double descriptor distance, determine o...

Abstract We propose a novel multi-view camera model for line-scan cameras with telecentric lenses. The supports an arbitrary number of and assumes linear relative motion constant velocity between the object. distinguish two configurations. In first configuration, all move independent vectors. second are mounted rigidly respect to each other therefore share common vector. can lens distortions by...

The objective of this research is to estimate the gaze point of a driver using epipolar geometry. The system requires two video inputs from internal and external views of a vehicle. We use SIFT image descriptor with L-2 norm distance to find putative correspondences, and then we use RANSAC algorithm to estimate robust fundamental matrix between two views. Once the underlaying scene geometry is ...

The principle underpinning stereo vision—comparing like but disparate images—is essential for calculating distances in applications that include 3D recognition, aircraft navigation, and motion analysis. A critical component of such calculations is matching image features, in particular corners and edges, which simplifies search space by extracting essential information from complex data. But fe...
