Importing images by looping through multiple folders

[akasch]

Hi,

Has anyone written a Python script that accesses images stored in different folders? I want the images in each folder to be placed into its own chunk.

So:

Folder A (with images 1, 2, 3) translates to Chunk A containing images 1, 2, 3
Folder B (with images 4, 5, 6) translates to Chunk B containing images 4, 5, 6

Does anyone have script that accomplishes this? Any help would be amazing.

Thanks!

I have a script which creates multiple documents using photos in multiple folders. You may be able to adapt it to create chunks instead.

Hi John,
would you be so nice to reupload the script?
It would be greatly appreciated!
Cheers!

Oh sorry, I'm moved it to a github repository. Here it is: https://github.com/notoes/PhotoscanWorkflow/blob/master/workflow.py

You'll be most interested in the section called "Project functions". The functions there iterate through folders and create new projects for each folder. You could do something like pass in a document to make_project() and comment out the lines where it creates a new document. The function creates a new chunk and adds photos to it.

All the best,
John

Hey John,
thank you very much! If you should be in my region of the map, I'll buy you a beer or two.
Cheers!

Hi again,
sorry to bother you but I've been trying to adapt your script to loop through already existing projects for decimating, retexturierung and exporting the models.
This works so far great but when applying this to a referenced chunk, I get "ERROR: Chunk is None".

I've been dabbling around for hours but am kind of stuck.
Any hints on what to change?

Here the output from console:

Hi Arie,

That was a lot of code to throw at you I've created a simpler script which will create a new PhotoScan document and add chunks containing photos from subdirectories.

https://raw.githubusercontent.com/notoes/PhotoscanWorkflow/master/example_multichunk.py

I've added comments to (hopefully!) make it easier to understand.

Have a look at the bottom of the file to see how the chunks are processed. I've added some example steps that you could uncomment. Or you could add your own steps here, like decimation. Check the PhotoScan.Chunk section Python API doc for examples of what you can do.

Best of luck!

John,
thank you so much. That's greatly appreciated. 
Can't wait to try that script tomorrow!
Cheers!
