Generally contour matching is diicult, and the problem becomes more diicult when the motion between successive image frames is large. When the image frames are obtained while the camera is in motion, we can use constraints about the scene and the camera. In this paper we propose a contour matching algorithm which guarantees an accurate matching result, even for large motion contours. The key id...

This paper presents an algorithm for interpolating intermediate views along a chain of cameras. There is no restriction on the camera placement as long as the distance between successive cameras is not too large. The interpolated views lie on a virtual poly-line defined by the (ordered) set of cameras. Our algorithm requires no strong camera calibration as the necessary epipolar geometry is est...

These lines are the intersections of the plane through the point p in the world and the centres of the left and right cameras with the two camera focal planes (see Figure 1). These epipolar lines are formed by the intersections of the pencil of planes through the line joining the image centres with the camera focal planes. Hence such lines form a pencil passing through the point of intersection...

This paper proposes polycentric panoramas as a general model of panoramic images. The model formalizes essential characteristics of panoramic geometry. It is able to describe a wide range of panoramic images, including those potentially of future interest, or previously introduced such as single-center, multi-perspective, or concentric panoramas [1, 5, 13, 16]. This paper presents geometrical f...

The problem of determining the camera motion from apparent contours or silhouettes of curved three-dimensional surfaces is considered. In a sequence of images, it is shown how to use the generalised epipolar constraint on apparent contours. One such constraint is obtained for each epipolar tangency point in each image pair. Thus in theory the motion can be calculated from the deformation of a s...

We propose a new rectification method for aligning epipolar lines of a pair of stereo images taken under any camera geometry. It effectively remaps both images onto the surface of a cylinder instead of a plane, which is used in common rectification methods. For a large set of camera motions, remapping to a plane has the drawback of creating rectified images that are potentially infinitely large...

In order to achieve a 3D, either Euclidean or projective, reconstruction with high precision, one has to consider lens distortion. In almost all work on multiple-views problems in computer vision, a camera is modeled as a pinhole. Lens distortion has usually been corrected off-line. This paper intends to consider lens distortion as an integral part of a camera. We first describe the epipolar ge...

Image resampling according to epipolar geometry is a prerequisite for a variety of photogrammetric tasks such as image matching, DEM and ortho-photo generation, aerial triangulation, map compilation, and stereoscopic viewing. The resampling process of imagery captured by frame camera has been established and implemented in current Digital Photogrammetric Workstations (DPW). Scanning analogue im...

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...

In this paper we show some results on Epipolar Geometry applying on various images using MATLAB. The Fundamental matrix is give to the depth information on the images we get the critical view of images that can be transfer in to the Grayscale image in to binary image. Matlab is an ideal tool for simulating digital communication system, its gates easy scripting language and excellent data visual...
