title: augmented reality measure size of objects - feasability
body: <p>I want to develop an app on android to measure the size of objects in a room. E.g. to measure the length of an edge of a table. For this purpose I would use "edge detection" either from imagej or from openCV. Then I would take this edge and define the length of a small part of it as a reference. With this part it is perhaps possible to calculate the whole length of the edge. Perhaps the vanishing point can help me with calculations of the length here.</p>
  
  <p>An example of what I roughly mean can be found here (at 1:19):

  <p>The Questions:
  1. Is there already an app like this?
  2. Would you rather recommend imagej or openCV (I know a little bit about NDK and native functions)
  3. It would be a project for a 3 month bachelor-thesis (means programming the stuff and in addition writing about 50 sites of text). What do you think about the feasibility concerning this fact AND feasibility in general?</p>
  
  <p>Any thoughts (also beside my questions) are greatly appreciated.
  Thanks in advance
