Given this formula for calculating the distance to an object as long as you have a picture of the object and know the actual height of the object...
distance to object (mm) = focal length (mm) * real height of the object (mm) * image height (pixels)
---------------------------------------------------------------------------
object height (pixels) * sensor height (mm)
What would be an accurate range of ratios of Focal Length and Sensor Height to approximate a human eye?
I think this question is sufficiently different from this one... and this one...
