I am using Hugin to create a mosaic of photos shot by a UAV. I have 60
photos organized in regular strips. The UAV flew at a constant height (70
m) on an area mostly flat. I have the necessity to georeference the
mosaic
obtained so I have to track the location of the shooting center in the
mosaic. Hugin records these coordinates but I do not understand in which
measurement unit ... how can I go back to the coordinates of the shooting
centers in terms of pixels? I don't have control points so I have to
georeference the mosaic using the UAV positions.
I don't know all of what is necessary to answer your question, but suspect
that the command line tool pano_trafo may be of assistance to you.
pano_trafo transforms image coordinates. You can provide a pair of image
coordinates (x,y) as input and it emits the corresponding panorama/mosaic
coordinates. Reverse transformation is also available.
If you know know the gps coordinates of the image centres, pano_trafo will
provide the corresponding coordinates in the mosaic, which should allow
you to georeference the mosaic, but there may be more to this than is
immediately obvious.
pano_trafo -h shows help.
Cheers,
