Inconsistent voxel scale #2

Closed Trainingzy closed 2 years ago

Trainingzy commented 2 years ago

Thanks for your code!

I am new to point clouds processing and I find the voxel scale used in VSS (10) is different from that in elastic (50). Will this inconsistency cause some problems?

Dingry commented 2 years ago

Hey, it doesn't cause a problem since voxelization in VSS just helps to detect non-object occupied positions as camera candidates. It does not need to be too precise, so a larger voxel size is sufficient for fast processing.

Thanks for the reply. I have one more question about voxelization. The voxel size is not fed to the voxelization function. How does it know the voxel size?

Dingry commented 2 years ago

Hi, the xyz is already scaled by the voxel size in the augmentation stage. https://github.com/CVMI-Lab/DODA/blob/master/dataset/augmentor/data_augmentor.py#L172.

Oh, I understand it now. Thanks!
