Epipolar Geometry — OpenCV 3.0.0-dev documentation
Goal In this section, We will learn about the basics of multiview geometry We will see what is epipole, epipolar lines, epipolar constraint etc. Basic Concepts When we take an image using pin-hole camera, we loose an important information, ie depth of the image. Or how far is each point in the image from the camera because it is a 3D-to-2D conversion. So it is an important question whether we can find the depth information using these cameras. And the answer is to use more than one camera.
