Title: reset_alignment
Post by: LDBL on December 22, 2018, 01:49:51 AM

Hello collective,

I'm trying to emulate the "reset current alignment" option in the GUI.

Essentially, I have a 'base' model I need to rebuild multiple times with different setting via python, but to do so, I need to be able to reset the current alignment each time.

My code thus far is;

Code: [Select]

import PhotoScan
doc = PhotoScan.app.document
doc.open('XXX.psz')
chunk = doc.chunk
chunk.matchPhotos(accuracy=PhotoScan.HighAccuracy, generic_preselection=True, reference_preselection=False, keypoint_limit=40000, tiepoint_limit=4000)
chunk.alignCameras(reset_alignment=True)
doc.save('XXX.psz')
But this fails. Selecting to reset alignment in the GUI works fine.

Any help please?

Thanks,

Leon

Hello Leon,

If reset_alignment parameter doesn't work, please try to use the following code:

Code: [Select]

for camera in chunk.cameras:
    camera.transform = NoneBut please specify, which version of PhotoScan you are using?

Hi Alexey,

Thanks for your quick reply, and apologies for my slow response.

To confirm, I'm using 1.4.3.

Will try the amended script now.

Cheers,

Leon

OK, so I've amended the code and tried running it and I'm still not getting a rebuild in the same way as with the GUI.

Is there something else I'm missing?!

Code is;

Code: [Select]

import PhotoScan
doc = PhotoScan.app.document
doc.open('/mnt/w/Coverack_PP/C1/C1_base_MA_TPA.psz')
chunk = doc.chunk
chunk.matchPhotos(accuracy=PhotoScan.HighAccuracy, generic_preselection=True, reference_preselection=False, keypoint_limit=40000, tiepoint_limit=4000)
for camera in chunk.cameras:
    camera.transform = None
doc.save('/mnt/w/Coverack_PP/C1/C1_40k_4k.psz')
Cheers,

Leon

Hello Leon,

Please try this:

Code: [Select]

import PhotoScan
doc = PhotoScan.app.document
doc.open('/mnt/w/Coverack_PP/C1/C1_base_MA_TPA.psz')
chunk = doc.chunk
chunk.point_cloud = None
chunk.matchPhotos(accuracy=PhotoScan.HighAccuracy, generic_preselection=True, reference_preselection=False, keypoint_limit=40000, tiepoint_limit=4000)
for camera in chunk.cameras:
    camera.transform = None
chunk.alignCameras(adaptive_fitting = False)
doc.save('/mnt/w/Coverack_PP/C1/C1_40k_4k.psz')

That's fixed it.

Legend, thank you!
