Hi guys, I need your help with next task:

  1. how to get top-down view from camera view.
  2. measuring real world distances in the picture (just on surface).

What i know or have:

  1. camera field of view (vertical, horizontal)
  2. camera picture resolution (vertical, horizontal)
  3. angle of camera view
  4. height of camera
  5. picture with compensated lens distortion.

I know, everything is about using next methods: warpPerspective(), getPerpectiveTransform, or similarly with affine transform.

But I really don't know how to correctly use it.

Thanks in advance David.

Hello Rogeeeer, first link, as you wrote, doesn't help to anything, because methods doesn't accept angle of camera. Unfortunately i am not able to solve it neither with the second hint. Believe me pls, I have read about it a lot.
