Differance in point cloud from old Agisoft and Metrashape
« on: February 26, 2021, 12:11:18 PM »
Hi

I noticed an differance in point cloud from old Agisoft and new metashape.
Im creating point clowk over an low forest area <5meters height of trees, and the tops of trees gets shopped off/rounded in metashape.
I'm running the same settings, well there arent that many settings to choose from more thatn qualety and filtering.
I have run both in meduim and mild.

Metashape produced a whole lot less noice than old agisoft witch is good.

Any ideas? Whats should I do differant?

Allign photos, medium, reference, Key 40'000, Tie 4000. Photo accuracy 0,1meter.
Optimize cameras
Build dense clud, medium quality, mild depth filtering.

I get differant output with lower height on trees in Metashape.

you have 15 million points on one cloud and 101 million on the other - maybe that's the difference

The difference in points count is huge. Are you sure you didn't use high quality settings in the old Agisoft? Also, which version is the old Agisoft and which the Metashape that you tried?

Nope same settings in both..
The Agisoft version was Agisoft 1.2 and Metshape 1.7.

Hello Invaidor,

If possible, please share the original image set that you are using for this project (or any other project where the difference is considerable) to support@agisoft.com, so that we could reproduce the difference and investigate the source of it. Additionally please share the PDF reports exported from both projects.
Best regards,
Alexey Pasumansky,
Agisoft LLC
