Hmm, I think we are talking about two aspects of the same issue. I was
thinking about calibrating a particular lens extents so to able to measure,
say, your flagpole. If on the other hand you know the flagpole is 10m high
and 100m away, then the lens calibration process is not required.

Good. Then we are in agreement. :-)
Your comments on spatial calibration are spot on.
