title: Is there a way to generate real time depthmap from single camera video in python/opencv?
body: <p>I'm trying to <strong>convert single images into it's depthmap</strong>, but I can't find any useful tutorial or documentation.</p>
  <p>I'd like to use opencv, but if you know a way to get the depth map using for example tensorflow, I'd be glad to hear it.</p>
  <p>There are numerous tutorials for stereo vision but I want to make it cheaper because it's for a project to help blind people.</p>
  <p>I'm currently using esp32 cam to stream frame by frame and receiving the images on python using opencv.</p>
