The model moves and rotates during creation.

[Helimax]

Hello,

When generating a model from the imported point cloud, it does not have the same position as the point cloud. It undergoes translation and rotation.

Hello Maxime,

What version of Metashape (including the build number) you are using?

Also please specify the coordinate system used for external point cloud import and coordinate system of the chunk set in the Reference pane settings dialog.

Hi,

Version is 2.1.0 build 17532. It seems to me that I have encountered this problem with older versions. But especially on small areas. On large areas this does not seem to happen.

When I import the point cloud, Metashape automatically detects the correct system : RGF93 v1 / Lambert-93 (EPSG::2154).

Then, in the parameters of references, I find the same system.

Thanks

Maxime

Hello Maxime,

We will try to reproduce the problem, but if you have a possibility to test it in 2.1.3 version, please let me know, if the same issue is observed for the same project.

The problem persists with version 2.1.3. build 18946...

Good evening

Hi
I get the same issue on this very large job. The whole job has moved and rotated.....Very strange , a bug Id say.
Thanks

Hello Allan,

Please describe the steps to follow.

Do you import point cloud to the empty chunk and generate model from it? If so, please specify, if you set the chunk's coordinate system before or after point cloud import, whether you import the point cloud as laser scans or not (or it you switch this property after import) and any additional information that could help to reproduce the problem on our side.

Hi Alexey,
I import the las files (100) then I merge them into 1. Remove all the others not useful. I then save the job, classify, build model from ground points, then i hit this issue....
Hope this helps.
Thanks
Allan

Please not I can create the model in the right place from a DEM, but get the error creating from the point cloud.

[Alexey Pasumansky]

Hello Allan,

Is the coordinate system of the chunk set to the same system used for the imported point clouds in the Reference pane settings dialog?

If the problem can be reproduced with 2 LAS files only, please send them via any convenient file transfer service to support@agisoft.com.

Hello Alexey,

A send you a small project as well as the corresponding LAS file.
This problem appears on all our small projects, but if we check the "split in blocks" option, this does not happen.

Thanks

Maxime

Hello Maxime,

Please confirm, if the issue is resolved in the latest 2.2.0 release version.
