Issue when exporting a tiled model in 1.8.2

[Grischa Hahn]

This error occurs as of version 1.8:

- Align images (128 x 12MP images/high)
- Save project
- Calculate tiled model (Medium, Tile size 1024, Smooth)
- Save project
- Export tiled model (Agisoft Tile Archive (*.zip)/PLY)

--> Export function stops at 100% and the memory runs completely full (up to 108GB RAM). After 20 minutes the export function is ready. Agisoft viewer crashes while loading the resulting zip file.

Version 1.7.6 works correctly.

Hello Grischa,

Can you please specify the number of levels in the tiled model, tiled model resolution and reference coordinate system used?

I use Windows 10 Pro.

I setup a Metashape project with 128 images in version 1.8.2 and save it as test.psx.

I open text .psx in version 1.7.6 and export the tiled mesh as Agisoft Tile Archive "test_1_7_6.zip" (Format PLY).
The file size is 128 MB. 7 second duration.

I open text .psx in version 1.8.2 and export the tiled mesh as Agisoft Tile Archive "test_1_8_2.zip" (Format PLY).
The file size is - after 7 seconds - 128 MB. Progress bar at 100%. Now the memory runs full and after 20 minutes the export is ready. The file size is now 5.9 GB.

I unpack both archive files. *.ply/*.jpg and *.dat are equal. But not the tiles.xml: 146 kB in 1.7.6 but 5785012 kB in 1.8.2! I am not able to open such a large xml file.

Attached the project information (Project settings 1_7_6.txt); the *.dat and *.xml of the "test_1_7_6.zip" archive.

Hello Grischa,

Thank you for sharing additional details, it seems that we were able to reproduce it on our side, so hopefully the fix will be included to the 1.8.3 version update.

Too late...


I have set up a smaller project with 3 images.

Attached are the tiles.xml files in the different Metashape versions.

The tiles.xml of version 1.8.2 is shortened, but shows the problem.

Hello Grischa,

Please try Metashape Pro 1.8.3 build 14176 pre-release:
https://s3-eu-west-1.amazonaws.com/download.agisoft.com/metashape-pro_1_8_3_x64.msi                             Windows
https://s3-eu-west-1.amazonaws.com/download.agisoft.com/metashape-pro_1_8_3.dmg                                    macOS
https://s3-eu-west-1.amazonaws.com/download.agisoft.com/metashape-pro_1_8_3_amd64.tar.gz                    Linux

Let me know, if the issue with Agisoft Tiled Archive export is resolved now.

Works perfectly now. Thanks!
