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.
An example of what I roughly mean can be found here (at 1:19):

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?
Any thoughts (also beside my questions) are greatly appreciated.
Thanks in advance

Take a look at the answer to this.
How can I determine distance from an object in a video?
