3d bounding box error

[simon.shan]

While generating synthetic data, I noticed that the 3D bounding boxes of some reconstructed assets are incorrect—the resulting bounding boxes are significantly larger than the actual objects. I’ve tried several approaches to resolve this, including:

1. Removing the extent attribute from the object mesh

2. Using bounding_box_3d instead of bounding_box_3d_fast in SDG

3. Combining both of the above methods

4. Using the compute_obb method

5. Rotate the object so that it aligns with the XY-axis. The bounding box of the original object and the rotated bounding box are as follows:

What should I do to fix this issue?
