Epipolar geometry of opti-acoustic stereo imaging
Europe Oceans 2005, 2005Optical and acoustic cameras are suitable imaging systems to inspect underwater structures, both in regular maintenance and security operations. Despite high resolution, optical systems have limited visibility range when deployed in turbid waters. In contrast, the new generation of high-frequency (MHz) acoustic cameras can provide images with enhanced ...

A GA-BASED APPROACH FOR EPIPOLAR GEOMETRY ESTIMATION
International Journal of Pattern Recognition and Artificial Intelligence, 2013In this paper, a genetic algorithm (GA)-based approach to estimate the fundamental matrix is presented. The aim of the proposed GA-based algorithm is to reduce the effect of noise and outliers in the corresponding points which affect the accuracy of the estimated fundamental matrix.

3D reconstruction with projective octrees and epipolar geometry
Sixth International Conference on Computer Vision (IEEE Cat. No.98CH36271), 2002In this paper, the problem of generating a 3D octree-like structure with the help of epipolar geometry within a projective framework is addressed. After a brief introduction on the basics of octrees and epipolar geometry, the new concept called "projective octree" is introduced together with an algorithm for building this projective structure. Finally,

Refractive Epipolar Geometry for Underwater Stereo Matching
2011 Canadian Conference on Computer and Robot Vision, 2011A fundamental component of stereo vision is that of epipolar geometry. It tells us that the corresponding point of a pixel in one image is restricted to a line in another image. This constraint reduces both the complexity of finding stereo correspondences and also the chance of making incorrect matches. When a refractive surface is introduced, which is

Epipolar Geometry Via Rectification of Spherical Images
2007For computation of the epipolar geometry from central-omni-directional images, the use of the spherical camera model is essential. This is because the central-omnidirectional cameras are universally expressed as the spherical camera model when the intrinsic parameters of the cameras are calibrated.
