title: Measuring in Kinect
body: <p>I'm trying to get started with Kinect, and it has a depth sensing camera, but I've seen no guidance on measuring width/height/lengths.</p>
  
  <p>Is it a matter of working out the distance an object is away from the camera (depth sensor) and at that range the field of view of the Kinect, and then working out how many pixels your object takes up?</p>
  
  <p>I'd like to be able to do a mesh or something from a dot-cloud and I'm having troubles figuring where to start and how to get proper width/height measurements for objects.</p>
