project taking too long to export Ortho
« on: September 09, 2013, 10:23:42 AM »
Hello,

I have a project using stable version 0.9.1.
The project has exactly 1781 photos taken by UAV and the area is about 318 hectares.
The align was done in about 6 hours using high accuracy.
For the geometry it took another 12 hours or so using high setting and smooth.
When I try to export with default pixel size and with split in blocks 10.000 x 10.000 it took 14 hours just for 3%. 8 hours for 10.000 x 10.000 resolution.
This is not normal because  the PC I'm using has 64 GB of RAM, Core i7 3.2 and 2 Nvidia GTX 680 running in SLI.
Normally for a project like this it would take about 16 hours of total processing and to export another hour in full res or 20 minutes for 10K.
I don't know what the problem with the project is. I am waiting for a response from Agisoft but until then I decided to write here as well.
Please if anyone knows a similar situation reply. I have done about 20 projects before without having this issue.
Note that the project has some areas with water. I did other projects with water and it had no problem. I used version 1 before and I uninstalled it in order to have a stable one. I though maybe some settings could have messed up but I  already did another smaller project without any issues.

Thank you!

Hello gheflorian,

We suggest that there are wrongly positioned cameras looking in the near horizontal direction. Please check the project and disable such cameras before orthophoto export.
Best regards,
