Hi Thomas,

I use Hugin since version 2009 - and I never saw that :-/

But we are talking from different things: this is the angle per pixel, but
> HFOV is the angle for the full pano. If you pano is not only 10 pixels wide
> the resolution per pixel is better then a hundredth of a degree given the
> precision of HFOV  by a tenth of degree.
> To play with your numbers: 3.5 m on 20 km correspond to 0.01 deg/pixel,
> with 10000 pixels wide this is a hfov of 100 deg. Taking a hfov of 101 deg
> (+1 deg)  changes to resolution by 0.0001 deg/pixel or 3 cm on 20 km (or
> with the current precision of 0.1 deg 3 mm on 20 km).
> Sorry, but you did not convince me.


You're right but the farthest I see, the greatest the error : report an
error of 3cm per pixel at 20km on a 10k px wide pano , and you'll get a
difference of 300 meters for the whole distance represented by the v/hfov .
While working with 0.01 it would only represent 30 meters, which is
negligible for such distance, from my point of view ...
