Ah ok thanks, I'd use a Prime lens because of the fixed focal length with a large depth of field because I have to identify the distances of multiple pedestrians at the same time. I'd know the focal length, field of view (angle of view), pixel density of the CCD, height of the camera above the...

The method I am trying to use assumes you know the height of the camera...
