Is Chunk Aligned?

[DrewFulton]

I am writing a batch script in Python to process a whole bunch of big projects while I am traveling over the next few weeks and don't need my computer.  I am new to the PhotoScan API so thought I'd ask here.  Is there a way to determine if matchPhotos and/or alignCameras has previously been run on the active chunk?  I don't want to have to rerun them if I have already done them previously.  I can check to see if things like a model exist to prevent rerunning those files but not sure about the align cameras functions.

Thanks!

Hello DrewFulton,

You can check if there is at least one aligned camera in the chunk (providing that you are not using Import Cameras function).

Checking if camera is aligned can be done in the following way:

Code: [Select]

flag = False
for camera in chunk.cameras:
      if camera.transform:
            print("Found first aligned camera")
            flag = True
            break
if not flag:
      print("no aligned cameras found")

Thanks Alexey!

I was trying something similar and looking for a camera that had a center location value.  I like yours better.

Any ideas on how to check if buildUV or buildTexture has been run?  Those are the last two steps I need to verify if possible.

Thanks!

Hello Drew,

I think you can check if chunk.model.tex_vertices and chunk.model.texture() are not None.

Thanks!  I'll give it a try.
