title: 3D scanning possible with OpenCV?
body: <p>this is a general question where I'm just looking for a starting point, not for a complete solution.</p>
  
  <p>I plan to do some 3D-scanning, means checking a surface and generationg a 3D model out of it. AFAIK there are two methods for it: one with a laser raster-scanning the whole surface and one with a camera where a grid is projected over the surface (not sure if one picture with this grid is enough or if more of it have to be done).</p>
  
  <p>My question: does OpenCV support the second method using the camera? If yes: which classes/functions are involved?</p>
  
  <p>All hints are welcome :-)</p>
