Point Cloud change position when filtered
« on: December 19, 2025, 05:24:30 PM »
When I filter my dense point clouds to ajust the point spacing for example, the whole dense cloud is moved and rotated.
I tried with and without having an action on the coordinates system but with no success.
Here's a video of my issue :

Thanks in advance.

Hello Cyril,

What version of Metashape you are using? Can you also make the screenshots from the same point of view of the original point cloud and of the tie points?

Hi and thanks for your answer.
I'm running Metashape Pro 2.2.3.21752
Here are screenshots from the same point of view.
Also a video capture of what happens (on another site)

Hello Cyril,

Can you please specify, what datasource you are using for the initial point cloud generation? Depth maps or tiled model?

On this example, I used Tiled model as source.

Thank you, Cyril, I was able to reproduce the issue for the point cloud based on the tiled model. I think we'll fix it in the upcoming update.

If it is common to work with the tiled model based point clouds, I can suggest a script for fixing the issue in the current version.

That's so very kind Alexey, I thank you much for your proposal.
It won't be necessery to do this for me as I haven't so much work of this kind to do and my simple turnaround is to generate directly from Tiled Model different PC in different resolutions.
Best regards and thanks for your answer, help and support.
Happy Christmas and happy new year.
