General / Split chunk and cameras for cloud processing

« Last post by Fabio Cassinelli on November 28, 2022, 01:41:48 PM »

Hi
Me and my team need to process a very large dataset using Agisoft Cloud.
We would like to align the cameras overall (to have a homogeneous alignment) and, after the alignment phase, split the data into several parts for processing.
We have managed to do this using the "split_in_chunks_dialog.py " script, but every chunk has in it all the cameras, so we have to upload on the cloud all the cameras for every chunk processing.
Is there an automatic way to not uploading all that data every time?

I always use Wavefront for the export format. I've never had a problem importing into Blender (v. 2.90.1).

Hello Agisoft Team

I use civil engineering, so i often use measure profile

but I want to use cross profile only one click.

Can I use this profile measurement?

General / Aerial Lidar data merge Terrestrial laser scan data

« Last post by TJ Jeong on November 28, 2022, 11:02:10 AM »

Hello Agisoft Team

I want to merge Aerial Lidar data(.las) with Terrestrial Laser scan data(ex. pts, ptx, e57...etc)

Las data has coordinate. but TLS data does not have coordinate(no georeference)

So how can i do this?

General / Re: Thermal Image Alignment using RGB Images

Hi Corensia,

just an idea, what about processing as camera rig, where the RGB photos are used for alignment?

General / Re: Standard Panorama stich

Hi bruno.camp,

search in the help of Metashape for the term 'station', you'll find:

Building panorama
Metashape is capable of panorama stitching for images taken from the same camera position - camera station. To indicate for the software that loaded images have been taken from one camera station, one should move those photos to a camera group and assign Camera Station type to it. For information on camera groups refer to Loading images to the project section.

To build panorama

1. Select the Build Panorama command from the Workflow menu.
2. Setting parameters for building panorama in the Build Panorama dialog.
3. Click OK button for starting generate panorama.
4. The progress dialog box will appear displaying the current processing status. To cancel processing click Cancel button

...

You might have a look at this tutorial too:

General / Model export quality

« Last post by adrian-var on November 28, 2022, 04:08:07 AM »

Hello everyone,

The model built in Metashape is very clean and wonderful (fig.1).

However, when I export the model and import it to blender/unreal. The UV seems broken (fig.2). The white walls messed with black triangles and became uneven.

Am I using the wrong export setting or any tips for this? Thanks.

General / Re: Building a mesh from Dense Cloud vs Depth Maps vs Tie Points

« Last post by cbnewham on November 28, 2022, 03:38:45 AM »

It's a lot faster without the extra step of generating a dense cloud and the results are superior - at least in my usage. I haven't used a dense cloud since Metashape standard edition was released with depth map capability.

General / Re: Metashape errors on NVIDIA A100X with CUDA 11.6

« Last post by djyoung on November 27, 2022, 11:53:41 PM »

Hi Alexey,

I only started using this system for Metashape about 2 months ago, and I've always gotten the same errors; it has never worked correctly.

I do not get these errors in the image matching stage, only dense point cloud stage. However, in the image matching stage, the GPU utilization, according to nvidia-smi, is usually only around 3%. During dense cloud (when the problems occur) utilization is usually around 50-75%.

I just ran a GPU stress test for 24 hours (https://github.com/wilicc/gpu-burn) on the same system. GPU utilization was around 99% and I got no errors.

Unfortunately I don't have the option of installing older drivers. I tried and it caused many package conflicts and I was unable to run nvidia-smi, and the system support told me it's not possible because of the way the vGPU system works (the driver needs to be set by the hypervisor, which allocates GPU slices to the VMs).

Is there any form of Metashape logging I can turn on that might help diagnose this problem?

Based on a suggestion in another thread (https://www.agisoft.com/forum/index.php?topic=11771.15), I tried to set the tweak "main/depth_max_gpu_multiplier" to "1", but it did not change anything. During the depth map/dense cloud stage, the terminal still says
[GPU 1] ...
[GPU 2] ...
[GPU 1] ...
[GPU 2] ...

and this is the stage where the problems occur. The way I tried to set the tweak using the python API is:
    Metashape.app.settings.setValue("main/depth_max_gpu_multiplier", 1)
Is this correct? Even when I do this, I still get [GPU 1] ... [GPU 2] ... , but I suspect the tweak is supposed to eliminate the [GPU 2] computations.

Any help would be much appreciated! Thank you.
