General / Tie points checkbox disabled in Merge chunk workflow

« on: October 30, 2023, 11:43:16 AM »

Merge Tie Points checkbox is disabled even when chunks have tie points. My understanding of it is that Merge Tie Points option requires key points to be present in the chunks that you are planning to merge.
I have tried with the following:
Merging chunks that were processed till Align Photos
Merging chunks that were processed till Dense Cloud
In both cases, Merge Tie Points checkbox was disabled.
Why is this happening and how to enable it?

What do the Merge Tie Points do in the Merge Chunks workflow? This option is disabled on every occasion even in the manual provided by Agisoft. Why is the option always disabled? On what condition is the option enabled?

General / How metashape divides tasks among network nodes?

« on: February 15, 2023, 12:26:08 PM »

I have a few questions on how the task distribution happens between nodes:
1. for different steps starting with Matching photos -> Aligning cameras -> Building dense cloud -> Building Mesh -> DEM -> ortho how these are bifurcated to smaller task?


If you have any article on this works under the hood because we need to understand how resource allocation works for different task.


While running workloads over network processing I've noticed that some of the nodes complete their tasks and sit idle. We can't move forward in the processing because we need to wait for that step to complete.

2. if the capabilities of different nodes are different then will metashape take that into account and give bigger tasks to bigger nodes and smaller tasks to smaller nodes?

Example:
Node 1
16 core CPU
8 core GPU
16 GB ram

Node 2
4 core CPU
1 core GPU
8 GB ram

will both the node be considered to be at par for running the small tasks provided or bigger tasks will be assigned to Node 1

Python and Java API / Getting error on nodes in Network Processing

« on: February 07, 2023, 11:47:10 PM »

Distro info:

Code: [Select]

Distributor ID: Ubuntu
Description:    Ubuntu 20.04.5 LTS
Release:        20.04
Codename:       focal

I'm using ubuntu 20.04 as server using the command:

Code: [Select]

./metashape.sh --server --control <server-ip> --dispatch <server-ip>
and two nodes running ubuntu 20.04 using commands:

Code: [Select]

./metashape.sh --node --dispatch <server-vol> --root <shared_storage_path> --platform offscreen

Then I use python script to connect to the server and send tasks to it, from the server itself.
Here are the python scripts:

Code: [Select]

client = Metashape.NetworkClient()
client.connect(socket.gethostname())
batch_id = client.createBatch(path[len(root):], network_tasks)
client.setBatchPaused(batch_id, False)


Just when this process starts the nodes start to throw error given below in infinite loop:

Code: [Select]

Python and Java API / Error while network processing

« on: February 02, 2023, 05:39:07 AM »

While running the script it mount the nfs and opens the project fine but it errors out in add photos.

Just FYI. The server VM is amazon linux and the nodes are ubuntu.
Logs:
[172.32.33.0:50080] failed #0 AddPhotos: Unexpected process termination

Python and Java API / How agisoft gets the origin for a 2D image

« on: April 12, 2022, 10:47:46 AM »

I'm trying to put gcp tagging information using the python api but for agisoft origin starts from different edges for different images. Which is the parameter that decides where this origin will start?

I've attached three images in which origin are at Bottom right, Top left and Top right respectively.

General / Addition of GCP images data using Python API

« on: March 08, 2022, 02:15:20 PM »

We want to first load GCP data in the form of comma separated values,

GCP label, X, Y, Z

here X, Y, Z are longitude, latitude and altitude.

And further we want to add GCP points to the chunk using the API in form of CSV again.

GCP label, Image label, X, Y

here X and Y pixel coordinates of the GCP in image.


What is the best possible way to do it?

This all takes too long than expected.

Bug Reports / std: bad_alloc error inside a ubuntu docker container

« on: December 01, 2021, 09:34:14 PM »

I'm trying to run metashape cli on an ubuntu docker container with 68 GB of RAM. I'm not sure if it is an out of memory error or not. I've also added 20 Gb swap also. Even then it fails with the same error. The dataset has 250 images. Looking at the memory usage profiles it doesn't seem to be a out of memory issue. Any ideas for the possible cause of failure.
