title: Opencv PNP in a Corridor
body: <p>I have reconstructed two frames using 5-point essential matrix, for sequential frames I am using PNP to get the camera pose before reconstructing the matches.</p>
  
  <p>When I use video frames progressing through a corridor the results of PNP are terrible?</p>
  
  <p>Is this a degenerate case?</p>
