title: How do I construct a 3D model of a room from 2 stereo cameras? What is the determining factor to an accurate construction?
body: <p>Currently, I have extracted depth points to construct a 3D model from 2 stereo cameras. The methods I have used are openCV graphCut method and a software from <a href="http://sourceforge.net/projects/reconststereo/" rel="noreferrer">http://sourceforge.net/projects/reconststereo/</a>. However, the generated 3D models are not very accurate, which leads me to question:
  1) What is the problem with pixel-based method?
  2) Should I change my pixel-based method to feature-based or object-recognition-based method? Is there a best method?
  3) Are there any other ways to do such reconstruction? </p>
  
  <p>Additionally, the depth extracted comes only from 2 images. What if I am turning the camera 360 degrees to obtain a video? Looking forward to suggestion on how to combine this depth information.</p>
  
  <p>Thank you very much :)</p>
