title: 3D reconstruction -- How to create 3D model from 2D image?
body: <p>If I take a picture with a camera, so I know the distance from the camera to the object, such as a scale model of a house, <strong>I would like to turn this into a 3D model that I can maneuver around</strong> so I can comment on different parts of the house.</p>
  <p>If I sit down and think about taking more than one picture, labeling direction, and distance, I should be able to figure out how to do this, but, I thought I would ask if someone has some paper that may help explain more.</p>
  <p>What language you explain in doesn't matter, as I am looking for the best approach.</p>
  <p>Right now I am considering showing the house, then the user can put in some assistance for height, such as distance from the camera to the top of that part of the model, and given enough of this it would be possible to start calculating heights for the rest, especially if there is a top-down image, then pictures from angles on the four sides, to calculate relative heights.</p>
  <p>Then I expect that parts will also need to differ in color to help separate out the various parts of the model.</p>
