Bug Reports / Wrong masks generation

« on: September 16, 2022, 06:01:42 AM »

Masks generation to mask defocus areas is cool feature and in about 95% cases work correct, but in about 5% cases they are partially inverted. I've attached example screenshots. Images 1_wrong.jpg and 2_wrong.jpg show wrong masks, but images 1_right.jpg and 2_right.jpg in the same areas with some different angle show correct masks. I've tried to decimate and smooth 3d model - it made some wrong masks correct but also it made some right masks incorrect.

General / Strange test results on different GPU

« on: September 04, 2022, 01:21:40 AM »

I found articles comparing different GPUs in Metashape and results very strange.
https://www.pugetsystems.com/labs/articles/Agisoft-Metashape-1-6-4---NVIDIA-GeForce-RTX-3080-Performance-1884/
https://www.pugetsystems.com/labs/articles/Agisoft-Metashape-1-6-5---NVIDIA-GeForce-RTX-30-Series-Multi-GPU-Performance-2009/

By combining data from these two articles dual 3080 only 10% faster than single 1080ti - can't believe that. By floating point tests results difference about +400%, I think difference in Metashape should be about that, definitely not 10%.

Tests were done using Metashape 1.6, but that version already supported acceleration for most features. Quote from 1.6 manual - "Metashape supports accelerated image matching; depth maps reconstruction; depth maps based mesh, DEM and tiled model generation; texture blending; photoconsistent mesh refinement operation due to the graphics hardware (GPU) exploiting"

Can anyone confirm that these articles absolutely wrong? How they get so wrong results?
