same here just did a ground classification on v. 2.0.1 and low points are wrongly classified (under roofs or over hangs, along walls). Definitely this did not occur with 1.8...

I'm getting the same problem.

Lets hope they found a fix.

Hello JM,

Thank you for additional information regarding the texturing issue, we will try to reproduce it on our side on a similar configuration and analyze the problem.

As for your question about GPU initialization line output, for OpenCL devices Metashape gets the "compute units" number from the driver reply upon CL_​DEVICE_​MAX_​COMPUTE_​UNITS call. It seems that for modern ADM graphic cards with RDNA architecture the command returns number of WGP (so-called "workgroup processors") which are actually dual compute units.
Additional information on this matter can be found here:
https://www.amd.com/system/files/documents/rdna-whitepaper.pdf
https://en.wikipedia.org/wiki/RDNA_(microarchitecture)#Differences_between_GCN_and_RDNA

However, Metashape is not relying on this output, the task of parallel computations on all available compute units is performed by GPU driver. You can check GPU load using dedicated utilities, such as GPU-Z, for example.


Alex thank you for the explication.

Regarding the 'Texturing' problem, if it reduce the pixel size from the original 0.0037561 to, for example pixel size = 0.006, i dont get constantly the error (just a 1 or 2 times).

Hope it helps!


best regards,
JM

Gonna use this thread to another problem:

Quote
[GPU 1] Using device: AMD Radeon RX 7900 XTX (gfx1100), 48 compute units, free memory: 24557/24560 MB, OpenCL 2.0

The 48 Compute Units are 'wrong' (?), It says 'Compute Units 96' https://www.techpowerup.com/gpu-specs/radeon-rx-7900-xtx.c3941


Could it be a bug?

edit. its because they are 2 chiplets with 48 in each one. But agisoft only saw 1 chip (48 cu) rather then the 2 chips (96 cu).

Any idea how to fix this, if possible?

Hello JM,

Can you please share the log from the beginning of Build Tiled Model task (or at least its texturing phase) and also the starting lines of Metashape from the Console pane?

Hi ALex,

Here it is the log

Hi,

So i'm getting the error following error doing texture blending in tiled model:

Currently using a 7900xtx with the latest drivers.


Any ideas why?

Camera Calibration / Re: Rolling shutter
« on: July 31, 2022, 06:03:36 PM »
Any news regarding this?
https://www.agisoft.com/forum/index.php?topic=14671.msg64383#msg64383

Regularized model is suitable for the case when the drone flies without turning the camera, i.e. during the shooting to a new route, the camera does not turn and the drone moves in parallel.
When using a Regularized, only two parameters are optimized for each frame: axis shift XY in the plane of the photo. When using the Full model, 6 parameters are optimized for each frame: shift along the XYZ axes and rotation along the XYZ axes.


Thank you for the explanation. Perfect!

« on: June 19, 2022, 06:06:57 PM »
Hello JM,

Can you send the mesh models exported with UV parametrization from both version projects to support@agisoft.com?

Sure, Alexey.


Thank you for the reply.

Bug Reports / Bad Texture Blending (1.8.3 vs 1.7.5)
« on: June 16, 2022, 12:03:41 PM »
Hi!

So i'm having some wierd bugs with texture blending in the latest version (1.8.3), only in some parts of the model, as you can see in the attachments. This doesnt happen in the 1.7.5 version.

Any ideas what could this be? A bug?


Its a 3D project (church) with around 1600 photos from various angles.


Thank you for the best photogrammetry software ever!  8)

Best regards,
JM
