Hi Alexey,

I've been re-running a few old projects through version 1.4 and noticed that after doing the initial alignment, the project files are MUCH larger than what is produced in previous versions of Photoscan.

One set of project files which weighed in at 10's of megabytes now comes in at 2.9Gb. Smaller  projects are also an order of magnitude larger.

It looks like the points0.zip object in the project file tree which I presume stores the sparse point cloud is taking up all the space. These projects have only 1 chunk, <900 photos each and have been aligned once on high before saving the whole project.

Any ideas on why this file is so huge?

Cheers,

J

Hello jbak9141,

Which processing settings you are using? Also is "keep key points" option checked on in the Advanced tab of the Preferences window?

Hi Alexey,

Apologies for the slow reply, we've checked the application config file and the relevant settings under preferences and can confirm that keep key points is not toggled on. We notice that the points_0.zip is consistently the largest component of the project files and often up to 7 GB for datasets with ~1000 photos.

Is there any other way to confirm that the key point descriptors are being kept?

Cheers,

J

Hello jbak9141,

Can you please then provide the Chunk Info information via the screenshot or processing parameters page from the Report file generated from this project?
