Answer 1

You can use the technique used by our eye to get perspective of depth and distance.

1) Get 2 images of the same object from two different camera positions.

The implementation is available at https://github.com/agnelvishal/Distance-between-camera-and-object Here is the research paper http://dsc.ijs.si/files/papers/S101%20Mrovlje.pdf
