General / How to update point cloud if i remove images ?
« on: March 12, 2024, 06:16:18 PM »
i'm doing some test to combine the use of Metashape and gaussian splatting.
Exporting camera algignement data with the python script is working well.

But if i remove cameras from the project (because for gaussian splatting need all cameras to be the same and same focal lenght) and make the export, the exported points still contains points from the removed cameras and this is create errors in gaussian splatting training.

Is there a way to "clean" the point cloud after having removed the cameras ?

Hi, i just tried the script but the sparse/0 folder is empty, no .bin files.

any idea ?

Does anybody know i can export the alignment result for gaussian splatting ?

I’m using Postshot :

Thanks for your reply,

how do i do this:
"If you know camera positions you can import them as reference."

General / Alignement issue with convex subject
« on: December 07, 2023, 11:37:33 AM »
I'm working on a convex surface and when i try to align, metashape si trying to make the tie points planar and the camera position gets convex itsefl instad of staying on the same plane.
Is there a way so taht metashape will align correctly in such a case ?

can you explain a little more how to do this:
 Save the exterior orientation information to CSV/TXT file and import it as a reference data after adding images to Metashape project ?

I'm using a robotic arm to take pictures in row/column. All images are perfectly :
* on the same plane
* have the same orientation

How can i use this information to help alignment ?
So far some time when overlap is to small the images are aligned on a round surface instead of a plane.
I would like to make the orientation fixed and if possible put them all on the same plane.


unfortunately, the link that you shared is behind a Weiss-Login-Wall, and is not accessible by the public. I'm referring to this link:

Could you please upload in a public location? Thanks!


i'm taking pictures using a robotic arm, so i know exactly the position of the camera for each photo.
How can i add this information to the pictures so that metashape can retrieve it ?

General / Mask issue (mask is small while processing and the bigger....)
« on: October 06, 2023, 04:32:57 PM »
Hi i have an issue with mask generation.

I try to make masks but when i select only one picture, i see the mask area being big or small depending on the defocus value while the mask is being generated but at the end when it's over, the mask get smaller leaving lot of unfocus area not masked.

don't know if it's clear...

it's the same if i select "current" or "selection".

What's happening?

Hi, how can i get the processing log if the computer crashes ?

General / Build Mesh is crashing my computer
« on: September 07, 2023, 12:57:04 PM »
i'm working on a 37500 images project.

When i try to build mesh, after a while i found my computer reset. As it's a big project, i never saw the crash live so i don't have any idea what's happening.

It's happening even if the region chosen is just a small part of the whole project.

Any idea to find the problem ?
