title: Libraries to get depth map from stereo images?
body: <p>I'm going to set up some devices to perform real-time 3D motion tracking. My first idea to do so is to use a pair of cameras to take stereo image and calculate the depth map to get the 3D data I needed.</p>
  
  <p>Are there any good open source libraries (C/C++) available and is fast enough for real-time(~12-24fps)?
  I've found <a href="http://sourceforge.net/projects/reconststereo/" rel="nofollow noreferrer">3D Reconstruction using Stereo Vision</a> and <a href="http://sourceforge.net/projects/estereo/" rel="nofollow noreferrer">EStereo</a> in SourceForge, have anyone tried them?</p>
  
  <p>Or any algorithm suggestion that I can implement?</p>
