title: Is it possible to measure distance to object with camera?
body: <p>Is it possible to measure distance to object with phone camera?</p>
  
  <p>I mean, in my application I start the camera, facing the camera to the object (lets say house) and then press the button and it calculates the distance and shows me in screen. </p>
  
  <p>If it's possible where I can find some tutorial or information about it?</p>
