title: Reconstruction a 3D point from two 2D points?
body: <p>OpenCV contains a lot of support for 3D reconstruction from stereo cameras. In my case i have two cameras, and I want to know 3D coordinates of some point. </p>
  
  <p>What i have:</p>
  
  <ol>
  <li>pixel coordinates of point on both images</li>
  <li>Known intrinsic and extrinsic  camera parametres</li>
  </ol>
  
  <p>What I want to get:
  Coordinates this point in 3D</p>
