enblend: warning: unable to run Dijkstra optimizer

[Hans Hermans]

Hello,

I am getting the following error by processing panoramic images with a bash script and the resulting image is missing some parts (see attached image):

enblend: info: loading next image: panorama0000.tif 1/1
enblend: info: loading next image: panorama0001.tif 1/1
enblend: warning: unable to run Dijkstra optimizer

The script is as followed:

#!/bin/bash

cd ~/Afbeeldingen/eyefi
count=$(ls -1 --file-type | grep -v '/$' | wc -l)

if [ "$count" -ge 5 ]; then
echo "start stichting"

cd ~/Afbeeldingen/eyefi

done

Any idea what is going wrong or how i can optimize the script?

I would first check to see if the autooptimiser stage had placed one of the photos in a position that was unstitchable. Look for something weird in the individual remapped output images from the nona step.

If you really want this script to always succeed, then you can turn off seam optimisation with the enblend --nooptimize parameter. Seam optimisation is only useful if you have moving objects in the scene.

adding --no-optimize works for the error in the output, but not for the black area.

The solution in the post "Enblend problem" dit the trick (--primary-seam-generator=nft)
