Camera for proximity detection?

Hi folks

Is anybody aware of any work being done to use a camera (or perhaps two cameras) for proximity detection? I appreciate that ultrasonic sensors are more widely used for this application and, while that seems to work for bats, we humans seem to manage with eyes. The ultrasonic thingies aren't expensive, but I've already got a camera on board.

Best wishes
Kevin

While it is possible, it is actually rather difficult.
Basically as humans we process many images to work out distance, not just one.

There is a good discussion on the topic here:

Thanks. I guess it's a research topic, rather than a piece of drop-in-code.
