I have zero doubts about surveillance cameras being able to estimate person’s height.
Obviously, you can use statistics to get a very close approximation. What I meant is that you can’t calculate her height using purely geometry because you don’t see her whole body. And the 1% error margin suggests a very precise calculation, not a statistical approximation.
Sorry, I got too single minded about my own uh, more broad attempt to answer your questions.
Ok, uh, yes, I also think a +/-1% margin or error based on just one ‘ruler’ (the phone) and then one angle… yeah, thats probably narrow to a silly degree, mainly because … there’s no actual explanation of how they determined the phone model/size.
But maybe I’m not explaining what I mean by body proportions.
If you know her upper arm length, her lower arm length, her hand/palm size, her head size, her neck to waist length, her waist width, her chest width, shoulder width, upper leg to knee length…
You can actually map all that onto an anatomical map that matches the rest of her fitness level, and you can get a pretty darn good guess how long her leg under the knee is.
I am of course assuming something like that was done, though that was not expliclitly shown.
She could be wearing platforms, that could throw that off, and if I had to guess just by eyeballing, she may be wearing roughly 1 to 2 inch heels, as I at least think she has a bit of forward pelvic tilt going on, and that could possibly explain the kind of staggered, leaning, off center stance… but again thats basically just an educated guess from having spent a good deal of time around ladies in boots and heels, lol.
I dunno, I guess I am trying to say there is probably more to this than what the image expliclitly shows, but that could very well be just… me projecting my own way that I would try to do this, into the image.
Guess I’m trying to say there’s more to it than this all being total bullshit, but also, yeah, … hard to say precisely how accurate this presented estimate actually is or isn’t.
Yeah, I get what you mean about proportions and I agree with everything you say. I just didn’t do a very good job of precisely explaining my thoughts in the original comment.

Hey no problem, it seems we eventually both ended up understanding each other’s ideas a bit better =P
