Ok I see what you are saying. My only critique is that you lumped relative measurements (ratios) into the mix.
With relative measurements you also get down to the thousandths of an inch. Photo units are just as precise as any instrument you use in your business. These are the units for relative measurements. We are measuring the image not the actual object. The restoration of the object from 2-D to 3-D is the source of the error not the instrument precision. That is where the interpretation comes in. You need to track reliable body markers relative to surface features to estimate where the joints are on the guy in the suit. Then associate them wrt a 3-D model. Any results would be contentious but it all depends on what you are trying to determine. It is a waste of time unless you can establish an acceptable range of uncertainty. What is acceptable? The only things we might be able to establish through measurement are the relative dimensions of Patsy and compare those values against an average human of the same approximate height. The height itself can be roughly determined through other means. There does seem to be enough information for estimating various ratios X microns/Y microns * 100. The accuracy and the meaning of it all remains to be seen.

It didnt start off that way but it got convoluted somewhere down the line while I was proving my point and yes, for brevity, I did start lumping them together

I disagree to a point ( depending on how you mean that) If you mean the "relative measurement" can be accurate in and of itself- yes, if you mean then you can use that relative measurement in any manner to accurately gauge an object without any known to place the range at, then no ( and I have never seen a certifying authority that would accept such or allow me to stamp it or standard that would accept it)

to a point, yes and if enough pictures are taken- thats not the case with the PGF. They can be reasonably accurate but nowhere near "precision"

yes

That "interpretation" was the sole basis of my stance. When that comes in, accuracy and certifiability goes out.

I agree with that 100%. IF we could track markers yes. ( then again, if those markers were there with any degree of accuracy, I would never have voiced dissention and we wouldnt be discussing this now) Its funny, ( if you were to search all the threads he and I had on this) you just summed up my entire argument.

Preach it brother, I'm there- thats all I have been saying

Insert "estimated" height and I'm there too. ( I wouldnt expect you to try to find all the threads and posts on it, but if you did) See, from day one, I never disputed that but the "counter argument" started off as though the film DID contain all the elements to measure it with extreme accuracy that would stand scrutiny and it hasnt been done yet. ( or various themes revolving around that core)
It wasnt until I unzipped an ASPRS manual and posted pics and the literal wording did others all of a sudden become "enlightened" and agreed with my premise and started piling on straw. ( thats when it got convoluted)
