I have bounding boxes detected in RGB images, but no information about the camera's intrinsic properties. Using deep learning (preferably) can I find the distance to the object from the camera in real world (meters or cm)? If I find the camera pose (using PoseNet) does that help?

  • $\begingroup$ What exact information are you going to have available using PoseNet? Their cambridge project has a wide margin of error. Also, have you got anything in your image whose exact size you know? $\endgroup$ – Lefty G Balogh Mar 11 '18 at 17:02
  • $\begingroup$ MonoDepth was published last year which uses stereo images to train the depth estimator. You could use their pre-trained models to estimate the depth of your image, and then only care about the objects you detected: visual.cs.ucl.ac.uk/pubs/monoDepth $\endgroup$ – Parker Lusk Mar 14 '18 at 17:47
