Abstract The discrete epipolar line, a discrete version of the epipolar line, is recently proposed to give geometric relationships between pixels in two different views so that we can directly deal with pixels rather than points in digital images. A method is then proposed to determine the discrete epipolar line providing that fully calibrated images are available. This paper deals with weakly ...

We exploit the following observation to directly find epipolar lines. For a pixel p in Image A all pixels corresponding to p in Image B are on the same epipolar line, or equivalently the image of the line spanning A’s center and p is an epipolar line in B. Computing the epipolar geometry from feature points between cameras with very different viewpoints is often error prone as an object’s appea...

In this paper we are interested in the calculation of the equation governing pairs of epipolar lines for unregistered images, i.e. when the image acquisition parameters are unknown or no calibration object is available. First we do a thorough analysis of the mathematics required to nd the epipolar line equations in the classical sense. Thereafter we show that for a broad class of stereo images ...

Area-based stereo algorithms, as the most universal of all stereovision methods, have the potential to become widely used in many industrial sectors, but their relatively low speed halt the usage. This paper describes the method which can significantly increase computing speed. This new method is called false epipolar constraint. It is an addition to epipolar constraint which can reduce the set...

-Line segments are ordinary in industrial scene, accurate line segments matching is a key step for many applications, such as 3-D reconstruction. A matching method based on epipolar-line constraint and line segment features is proposed. Firstly, the points on line segments between image pairs are matched by epipolar-line constraint. Secondly, geometric descriptor and gray value descriptor are u...

High-resolution satellite imagery is expected to be a major source of 3D measurement of ground, especially automatic stereo plotting to generate DEM by stereo matching technology is highly required. Epipolarity is a very useful concept in processing stereo imagery, and it has been widely used in process images captured by frame cameras. Different from perspective image, every scan line of linea...

In this paper, we are going to answer the following question: assuming that we have estimates for the epipolar geometry and its uncertainty between two views, how probable it is that a new, independent point pair will satisfy the true epipolar geometry and be, in this sense, a feasible candidate correspondence pair? If we knew the true fundamental matrix, the answer would be trivial but in real...
