duplicate chunk (chunk.copy) & resetting alignment - bad results after new align

[mcstieg]

Hello Alexey,

for a code that

• duplicates a chunk for
• testing several match and
• alignment parameters

I need your help.

I'm duplicating a chunk to use my photos and masks again in some other chunks to test different parameters. But  I recognized, that the alignment results of my code are worse than using the same parameters in a new chunk (or via GUI), where I load the photos and masks manually.
So what am I doing wrong?

To make it short:   

Code: [Select]

chunk = chunk.copy(keypoints=False)
for camera in chunk.cameras:
                camera.transform = None
chunk.point_cloud.removeKeypoints()
chunk.point_cloud = None
chunk.remove(chunk.markers)
Then I match and align photos (reset matches = True).


Thank you!!!

Hello mcstieg,

Can you share the project with two chunks - results in new chunk (good), results in duplicated chunk (not so good)? If it is possible, please send the project (as PSZ of PSX+files folder) to support@agisoft.com.

Hello Alexey,

hopefully it will be a good new year for you!

Can you please tell me the currently best way to fully clear an alignment when duplicating a chunk? Still having problems some times when doing this.
Is it necessary to remove tiepoints, keypoints... or should "tranform=none" do the job?

Thank you very much!
