title: Using the epipolar line in a search algorithm to find corresponding points in two camera images
body: <p>In computer vision, specifically computational stereo, we can easily write an algorithm to find corresponding points in the two camera images.  The algorithm can be written in pseudo-code like this:</p>
  
  <pre><code>Repeat for each feature point in the left image {
     calculate the epipolar line in the right image 
     if the epipolar line intersects only one feature point 
     then match those points and remove them from the lists
  }
  Until no feature point can be matched uniquely
  </code></pre>
  
  <p>My question is how can this algorithm be changed if three cameras are used instead of the standard two camera setup?</p>
  
  <p>Just some good ideas or some altered version of this pseudo code would be brilliant.</p>
  
  <p>Thank you.</p>
