General / Re: mesh generation extremely low cpu and gpu usage
« Last post by Bzuco on August 04, 2022, 05:37:34 PM »
30-40MB/s is exactly limit of USB2.0 .But if you already have that disk connected in USB 3.0, then it should not slow the process much. Also generating mesh from depthmaps is not 100% multi threaded, there are also few tasks single threaded.
Can you describe a little bit more about your project and settings you are using? ...resolution of depth maps?, it is drone top down photorammetry? from how large area are you trying generate the mesh?...

Hi, like you said - it seems to be Input/Ouput-bound (i.e. IO is slow - see also 98% IO in logs). Can you transfer your project from external drive (WB My Book) to local internal disk for processing? (to SSD ideally)

General / Hiding camera groups
« Last post by 2tall3ne on August 04, 2022, 06:57:34 AM »
Is there a way to hide camera groups? I have organized my chunk with multiple camera groups based on runlines and area. I want to view a certain group with another and no others...is that possible?

General / Problems aligning big Dataset in one aligment
« Last post by 4DS Niklas on August 03, 2022, 11:16:29 PM »
Hello everyone,

i have a dataset of ~2400 images capturing a schoolbuilding.

When trying to align these images, only 1750 got aligned in one attempt. I aligned the others in 2 seperate chunks, which worked fine.
I planned to try to align the chunks together using Align Chunks point based, but it also did not seem to work.

I have 2 chunks containing images capturing the buildings facades at low distances at mostly 0°, and one chunk capturing the building from above at -90° to roughly -50°.
In my experience, the overlapping areas should be more than enough to get the images to align in one go, but i cannot seem to get it working.
Any ideas what i could do differently to get these images to align in one go?
I attached images of the chunks where i marked the same facade in each for better orientantion.

Python and Java API / Filter photos by marker using Python API
« Last post by aniket@aus.co.in on August 03, 2022, 09:31:15 PM »
The filter photos by marker work very well on GUI. I need to get the same result of filtering photos using the python API. Is there any way to do it?

and also is there any way to find the approximate positions for the markers on the images?

General / mesh generation extremely low cpu and gpu usage
« Last post by bassistas on August 03, 2022, 05:44:24 PM »
Hi guys,
I'm trying to create a mesh from 50 laser scans and 2788 (50mpixel) photos but after the generation of the depth maps the CPU and GPU usage is dropping to almost 0-3% and only the disk usage activity hovers around 30-40mb/sec as you can see in this screenshot. If I leave it like that the estimated time starts to explode and shows 8 to 10 days or more which is extreme for such an amount of data and the hardware I use. Is this a metashape bug? I'm using the latest 1.8.4 build.

General / Re: Camera recommendations still up-to-date?

The Canon EOS R is a great bit of kit, I captured this cube with it on a turntable. I used an EF 100mm L lens.
The turntable setup was a Foldio3.

Thank you very much, that cube looks great. The EOS R seems to be quite a bit more expensive than the Sony A6000 - is it worth the extra money?

Bug Reports / Re: Texture missing when using GPU
« Last post by Daniele on August 03, 2022, 05:10:45 PM »
Dear Alexey,
just to inform you that after getting in touch with your support team, I solved my problem which was not related to the last version of Metashape but to bad NVIDIA drivers.

So I have totally uninstalled the NVIDIA driver with Display Driver Uninstaller and manually installed one old driver from here: https://www.nvidia.com/Download/Find.aspx
Now texture blending works again with GPU enabled. Also works fine with the last version 1.8 of metashape. 

Thanks for your support, and sorry for the trouble.

Best regards,
Daniele

General / HDD vs SSD - data processing time
« Last post by pttpx2 on August 03, 2022, 04:45:31 PM »
Hello,

I'm using Metashape which is installed on HDD and now I'm planning to buy a new disk. I'm thinking about buying SSD. Of course it's more expensive so please tell me if I installed Metashape on SSD would it shorten time of data processing?

I have once seen Metashape on SSD computer and I've noticed that photos are imported into the program way faster but I'm wondering if it will also impact data processing time.

My computer specification:
CPU: AMD Ryzen 5 2400G with RADEON Vega graphics
graphics: NVIDIA GeForce GTX 970
RAM: 16 GB

Cheers!

Bug Reports / Re: Build Mesh: Custom Face Count (Pro version) - being ignored
« Last post by sibmaster on August 03, 2022, 02:56:51 PM »
Hey Alexey! Thank you for the fast reply.

I used Metashape Professional Version 1.8.3 build 14331. And I put the custom face count into the GUI.
