cloud deformation after "Optimize camera alignment"

[barrubba]

1. i've aligned photos with check on.
2. uncheck all photos
3. import 8 gps gcps coordinates and pin all markers on all photos,
4. click on optimize and result is a distorted cloud

why?

any other advice, reading photo data in attached file?

Hello barrubba,

Have you selected the coordinate system that corresponds to the GCPs in the Reference pane setting dialog before the optimization?

thanks.. wrong wgs84 !
now i've checked right system and is fine i think..
At this point, how i can evaluate precision of referencing?
is error  in tab acceptable?
