N pics, one non-interactive run, sane defaults

[Thomas Güttler]

Hi,

is there a way to get the following?

I give hugin a directory containing N images. All N images should be created
to one panorama. The directory does not contain other images.

hugin runs (for some minutes) and creates the panorama in a file called panorama.jpg.

I mean the run should be **non-interactive**. Hugin should choose sane
defaults.

If I am not happy with the defaults, I can still call hugin by hand.

Whatever you think "sane" is.

Hugin comes with a batch processor, see

Sane is for me democracy: Take 100 average users. If 20 want default value A, 40 want default value B, 30 want C, 10 are unsure,
then the sane default is value B.

Thank you.

Unfortunately you could not find a way to get my use case solved with this tool

The tool seems to be build for running several pto project files at once.

I don't have a pto file. I just have one directory with N pictures and the result should be one panorama.jpg.

Maybe I was blind, but I read your above link twice.

read chapter http://wiki.panotools.org/PTBatcherGUI#Image_sets_.28create_project_files.29
also http://wiki.panotools.org/Hugin_Panorama_Workflow provides some more informations.

or you could write a script to process all the images in the dir.

Thank you T. Modes for the links.

My script now looks like this:

{{{
#!/bin/bash
# Usage: panorama.sh dir_containing_images_to_stitch
set -x

cd $1

pto_gen -o project.pto *.jpg *.JPG
cpfind -o project.pto --multirow --celeste project.pto
cpclean -o project.pto project.pto
linefind -o project.pto project.pto
autooptimiser -a -m -l -s -o project.pto project.pto
pano_modify --canvas=AUTO --crop=AUTO -o project.pto project.pto
}}}

A project.pto gets created.

Now the stitching needs to be done.

If I call this now:

 PTBatcherGUI project.pto output_prefix

the GUI with the batch-jobs opens. But it does not start automatically.

How to start the processing via script?

[Thomas Güttler]

I found the option to start stitching ...

Here is the script.

Any suggestions for improvements?

{{{
#!/bin/bash
# Usage: panorama.sh dir_containing_images_to_stitch
set -x

cd $1

basename=$(basename $PWD)
pto_gen -o ${basename}.pto *.jpg *.JPG
cpfind -o ${basename}.pto --multirow --celeste ${basename}.pto
cpclean -o ${basename}.pto ${basename}.pto
linefind -o ${basename}.pto ${basename}.pto
autooptimiser -a -m -l -s -o ${basename}.pto ${basename}.pto
pano_modify --canvas=AUTO --crop=AUTO -o ${basename}.pto ${basename}.pto
PTBatcherGUI ${basename}.pto $basename --batch
notify-send "Created panorama $basename"

You could call hugin_executor.
An example script is attached, modify as appropriate, and see if this
approach helps.

[Thomas Güttler]

Hi,

hugin_executor is not installed on my laptop. I use ubuntu 14.04.

I uploaded my script here:

https://github.com/guettli/panorama

It takes a directory containing jpg-files and outputs a file called
panorama.jpg.

All in batch, not interactive.

Feedback welcome.

Sorry, I assumed you were running Hugin-2015.0.0.
To use the makefile stitching system ( pre hugin-2015.0.0) simply replace
calls to hugin-executor with...

pto2mk -o project.mk -p $Prefix project.pto
make -j 2 -f project.mk all

My understanding of python code isn't the best.
What are the advantages of your python script over using using Hugin's
command line tools in a shell script or a batch file?

I booted my Ubuntu 14.04 partition and checked. It offers only Hugin 2013.

You can download hugin 2015.0 for all active Ubuntu versions from
https://launchpad.net/~hugin/+archive/ubuntu/hugin-builds

If you feel brave, you can even use
https://launchpad.net/~hugin/+archive/ubuntu/nightly
for the current development version.

With kind regards

Hi Tduell,

I use the shell daily, but only for interactive usage.

I stopped scripting with the shell some years ago. I don't like the shell for scripting

since:

 - The shell does not know the concept of exceptions or stacktraces.

 - The shell goes to the next line if something is wrong. I want the programm to stop, not to proceed.

 - The shell has major problems handling filenames which contain special characters.

does this answer your question? Feel free to ask more details :-)

[David W. Jones]

Thanks, I only mentioned what version Ubuntu 14 offers because that's
what the OP mentioned he was using. My Ubuntu partition is mostly there
because the manufacturer put it there and my laptop's webcam only
appears to work under Ubuntu. Everything else I use on my laptop is
Debian Sid.

It knows about exit statuses (see next)

Use the -e flag.

-e Exit immediately if a pipeline (which may consist of a single simple command), a list, or a com‐
pound command (see SHELL GRAMMAR above), exits with a non-zero status.

Use quotes.
