Vector too long

[Carlos E]

How can I solve this error:

Vector too long

?

It appears doing when generating a 3D Model.

Thank you very much in advance.

Hello Carlos,

Please check, if you observe the same problem in 2.2.1 release version.

Also please specify if you really need 2.5D mesh model surface to be generated from the dense point cloud? Usually DEM is generated when 2.5D surface is requried.

Thanks for your answer. Actually, I have to downgraded to the 2.1 version because the 2.2 version hanged so often.

There is not need at all to generate 2.5D mesh model. I was not working in any particular survey. My idea is to know the influence of the processing parameters, the surface of the survey  and the PC configuration in the processing time (medium vs high quality / Key limit point 40000 - Tie point limit 10000 vs Key limit point 10000 - Tie point limit 1000; Surface type: 2.5D vs 3D... and so on). So, I created two Batch Process (High quality vs Medium quality) and sometimes that error appeared

Hello Carlos,

If the problem only occurs for 2.5D mesh generation, please specify the number of points in the source point cloud and, if possible, share the screenshot of the point cloud overview to understand better the type of the project.

And at 90% the programm crashs!

As I said before I am conducting several test just variying the parametres. When I process the FULL cloud point, (760117736 points) everything is fine, but when I select the points with a level of confdence greater than 3, is where the problems begin.

The description of the survey is an olive grove located on slightly sloping terrain

Hello Carlos,

According to the screenshot the point cloud is not referenced, this could happen due to the bug of some old Metashape version.
To fix the problem in the current version you need to input and execute the following code to the Console pane, having the problematic point cloud active in the active chunk:

Code: [Select]

Metashape.app.document.chunk.point_cloud.transform = Metashape.Matrix.Diag([1,1,1,1])

Thanks a lot for your help
