Workflow for Creating High Resolution Panos

Tools used

• Darktable for raw processing
  • sudo add-apt-repository ppa:pmjdebruijn/darktable-release
  • sudo apt-get update
• Hugin for Stitching
• Gimp/Darktable for final post processing

Darktable

1. Default Processing (Rotation, Base Curve, Sharpening)
2. Lens Correction
3. White Balance according to conditions
4. Dust Removal when necessary
5. Equalizer when necessary
6. Apply to all images
7. Export all images as tif

Hugin

0. Create image stacks when necessary
   • find -name IMG*.tif -print | sort | xargs -t -n3 sh -c 'align_image_stack --gpu -t 1 -i -C $0 $1 $2 -o $0.hdr'
1. a) Add images or stacks to pto
   • pto_gen *.<tif|hdr> -s3 -o pano.pto b) Select Specific exposures out of a stack to be added to pto file
   • find -name IMG*.tif -print | sort | xargs -n3 sh -c 'echo $1' | xargs pto_gen {} -o pano.pto
2. PreAlign Images according to pitch and yaw of bot
   • pto_var --set="p=floor(i/16)*4,y=(i%16)*3" pano.pto
3. Freeze unconnected images
   • geocpset -o pano_var_set.pto pano_var.pto
