3D reconstruction disparity mapping

Stereo vision is the extraction of 3D information from digital images, such as obtained by a CCD camera. By comparing information about a scene from two vantage points, 3D information can be extracted by examination of the relative positions of objects in the two panels. Stereo images tell us the information of the camera and its spacing by the different images that are captures using it. Stereo images use essential and fundamental matrices to estimate planar disparity between the images. The inliers between the images are calculated using the usual method of homography calculation. Estimation of the fundamental matrix helps us in knowing the disparity. Here in the
project we are trying to estimate the fundamental matrix and then based on that estimate the vertical and horizontal disparity maps.
