Perhaps this link might help … I had to read it very carefully a few times … even though English is my first language. The picture in the link is from the perspective of someone looking down on you standing at the origin 0,0,0. >From your camera's point of view taking the picture looking at the “Projection >Plane”: X is the camera moving left-right (-ve to +ve), Y is the camera moving >down-up (-ve to +ve), and Z is in-out (-ve to +ve … “in” being closer to the >projection plane) If you’re in a plane taking a picture straight down just think from you point of view as laying down pointing the camera straight down … so Z is “in” to the ground (it’s always relative to what your camera is looking at). I believe from this then that TRx of 0.521 being 30cm is relative to the “Projection Plane” at Z=-1 (and the panosphere radius r=1); r must be at about twice (1/0.521=1.919) 30cm or 57.6cm.
