Estimate distance using camera #2132

Track both the point of interest and device rotation to estimate distance using parallax. More research needed.

This might be able to estimate object size as well if distance can be estimated automatically (clinometer)

Potentially leverage stereo cameras if the device reports distance between cameras

Another idea by @RandomGuy0400 could be to leverage the autofocus system / IR rangefinder if this is possible.
