What is stereo matching algorithm?
Stereo matching or disparity estimation is the process of finding the pixels in the multiscopic views that correspond to the same 3D point in the scene. The rectified epipolar geometry simplifies this process of finding correspondences on the same epipolar line.
What is a disparity map?
A disparity map, often referred to as a depth map, is an image which contains depth information of every pixel stored in it. The term disparity in stereo vision refers to the apparent shift in pixel or motion in a pair of stereo images.
