the output mesh and point cloud are not oriented in the same way

[dorothea-n-1]

Hello, I'm new to using Meshroom.

I'm trying to model bunches of grapes so that I can then calculate the volume of these bunches and thus estimate the yield.

When I open the texturedMesh from "Texturing" or the point cloud from "ConvertSfMFormat" in Cloudcompare or Meshlab, the two models (mesh vs point cloud) are not in the same orientation. One is right side up and the other is 'on its head'.

Here is an image of the point cloud in cloudcompre :

Here is an image of the mesh in cloudcompre :

I use :

• win 10
  • Python version 3.7.4
  • Qt/PySide version : I don't know where to find the information ?
  • Meshroom realse version: 2023.2.0
  • Binary version : I don't know where to find the information ?
  • Commit reference : I don't know where to find the information ?

Thank you for your help. I hope my information has been complete enough. Beste regards Dorothea

Hi. Is there any progress about this problem? I'm sorry to trouble you again. I encounter the same question and I would be extremely grateful if you could help me. @natowi

I think internally point cloud and mesh use different coordinate system orientations. Use the SfmAlignment or SfmTransform node to align them. This may be a version specific issue.

Thanks. I think this is surely caused from different coordinate system, a post-process can handle this problem.
